The name of this company is Datadog, Inc. (the “Company”).

The address of the registered office of the Company in the State of Delaware is 251 Little Falls Drive, City of Wilmington, County of New Castle, 19808 and the name of the registered agent of the Company in the State of Delaware at such address is Corporation Service Company.

III.

The purpose of the Company is to engage in any lawful act or activity for which a corporation may be organized under the General Corporation Law of the State of Delaware (“DGCL”).

IV.

A. The Company is authorized to issue three classes of stock to be designated, respectively, “Class A Common Stock,” “Class B Common Stock” and “Preferred Stock.” The total number of shares that the Company is authorized to issue is 2,330,000,000 shares, 2,000,000,000 shares of which shall be Class A Common Stock (the “Class A Common Stock”), 310,000,000 shares of which shall be Class B Common Stock (the “Class B Common Stock” together with the Class A Common Stock, the “Common Stock”) and 20,000,000 shares of which shall be Preferred Stock (the “Preferred Stock”). The Preferred Stock shall have a par value of $0.00001 per share and the Common Stock shall have a par value of $$0.00001 per share. From and after the Effective Time (as defined herein), each share of common stock, par value $$0.00001 per share, of the Company (“Pre-IPO Stock”) issued and outstanding immediately prior to the Effective Time shall automatically be reclassified as and become one share of Class B Common Stock. Certificates representing shares of Pre-IPO Stock prior to the Effective Time shall, from and after the Effective Time, no longer represent shares of Pre-IPO Stock and shall represent only the number of shares of Class B Common Stock into which the shares of Pre-IPO Stock previously represented by such certificate were reclassified pursuant hereto.

B. The Preferred Stock may be issued from time to time in one or more series. The Board of Directors of the Company is hereby expressly authorized by resolution or resolutions to provide for the issue of all or any of the shares of the Preferred Stock in one or more series, and to fix the number of shares

of such shares and to determine for each such series, such voting powers, full or limited, or no voting powers, and such designation, preferences, and relative, participating, optional, or other rights and such qualifications, limitations, or restrictions thereof, as shall be stated and expressed in the resolution or resolutions adopted by the Board of Directors providing for the issuance of such shares and as may be permitted by the DGCL. The Board of Directors is also expressly authorized to increase (but not above the authorized number of shares of Preferred Stock) or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series subsequent to the issuance of shares of that series.

C. The number of authorized shares of Preferred Stock, Class A Common Stock or Class B Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of all of the outstanding shares of stock of the Company entitled to vote thereon, without a separate vote of the holders of the Preferred Stock, or of any series thereof, Class A Common Stock or Class B Common Stock unless a vote of any such holders is required pursuant to the terms of any certificate of designation filed with respect to any series of Preferred Stock.

Except as permitted in Section 2(b), any dividends paid to the holders of shares of Class A Common Stock and Class B Common Stock shall be paid pro rata, on an equal priority, pari passu basis, unless different treatment of the shares of each such class is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A Common Stock and a majority of the outstanding shares of Class B Common Stock, each voting separately as a class.

4. Voting Rights.

(a) Class A Common Stock. Each holder of shares of Class A Common Stock shall be entitled to one vote for each share thereof held.

(b) Class B Common Stock. Each holder of shares of Class B Common Stock shall be entitled to ten votes for each share thereof held.

(c) Voting Generally. Except as required by law, the holders of Preferred Stock, Class A Common Stock and Class B Common Stock shall vote together and not as separate series or classes. Except as otherwise required by applicable law, holders of Class A Common Stock and Class B Common Stock, as such, shall not be entitled to vote on any amendment to the Certificate of Incorporation that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Certificate of Incorporation or applicable law.

5. Optional Conversion.

(a) Optional Conversion of the Class B Common Stock.

(i) At the option of the holder thereof, each share of Class B Common Stock shall be convertible, at any time or from time to time, into one fully paid and nonassessable share of Class A Common Stock as provided herein.

(ii) Each holder of Class B Common Stock who elects to convert the same into shares of Class A Common Stock shall surrender the certificate or certificates therefor (if any), duly endorsed, at the office of the Company or any transfer agent for the Class B Common Stock, and shall give written notice to the Company at such office that such holder elects to convert the same and shall state therein the number of shares of Class B Common Stock being converted. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the certificate or certificates representing the shares of Class B Common Stock to be converted, or, if the shares are uncertificated, immediately prior to the close of business on the date that the holder delivers notice of such conversion to the Company’s transfer agent and the person entitled to receive the shares of Class A Common Stock issuable upon such conversion shall be treated for all purposes as the record holder of such shares of Class A Common Stock at such time.

6. Automatic Conversion.

(a) Automatic Conversion of the Class B Common Stock. Each share of Class B Common Stock shall automatically be converted into one fully paid and nonassessable share of Class A Common Stock upon a Transfer, other than a Permitted Transfer, of such share of Class B Common Stock. Such conversion shall occur automatically without the need for any further action by the holders of such shares and whether or not the certificates representing such shares (if any) are surrendered to the Company or its transfer agent; provided, however, that the Company shall not be obligated to issue certificates evidencing the shares of Class A Common Stock issuable upon such conversion unless the certificates evidencing such shares of Class B Common Stock are either delivered to the Company or its transfer agent as provided below, or the holder notifies the Company or its transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Company to indemnify the Company from any loss incurred by it in connection with such certificates. Upon the occurrence of such automatic conversion of the Class B Common Stock, the holders of Class B Common Stock so converted shall surrender the certificates representing such shares (if any) at the office of the Company or any transfer agent for the Class A Common Stock.

(b) Conversion upon Death. Each share of Class B Common Stock held of record by a natural person, including a natural person serving in a trustee capacity, other than a Founder (including a Founder holding shares in a trustee capacity) or a Permitted Transferee of such Founder, shall automatically, without any further action, convert into one fully paid and nonassessable share of Class A Common Stock upon the death of such natural person. Each share of Class B Common Stock held of record by a Founder (including a Founder holding shares in a trustee capacity) or a Permitted Transferee of such Founder shall automatically, without any further action, convert into one fully paid and nonassessable share of Class A Common Stock nine months after the date of the death of such Founder.

(c) Final Conversion. On the Final Conversion Date, each issued share of Class B Common Stock shall automatically, without any further action, convert into one share of Class A Common Stock. Following the Final Conversion Date, the Company may no longer issue any additional shares of Class B Common Stock. Such conversion shall occur automatically without the need for any further action by the holders of such shares and whether or not the certificates representing such shares (if any) are surrendered to the Company or its transfer agent; provided, however, that the Company shall not be obligated to issue certificates evidencing the shares of Class A Common Stock issuable upon such conversion unless the certificates evidencing such shares of Class B Common Stock are either delivered to the Company or its transfer agent as provided below, or the holder notifies the Company or its transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Company to indemnify the Company from any loss incurred by it in connection with such certificates. Upon the occurrence of such automatic conversion of the Class B Common Stock, the holders of Class B Common Stock so converted shall surrender the certificates representing such shares (if any) at the office of the Company or any transfer agent for the Class A Common Stock.

(d) Procedures. The Company may, from time to time, establish such policies and procedures relating to the conversion of Class B Common Stock to Class A Common Stock and the general administration of this dual class stock structure, including the issuance of stock certificates (or the establishment of book-entry positions) with respect thereto, as it may deem reasonably necessary or advisable, and may from time to time request that holders of shares of Class B Common Stock furnish certifications, affidavits or other proof to the Corporation as it deems necessary to verify the ownership of Class B Common Stock and to confirm that a conversion to Class A Common Stock has not occurred. A determination by the Secretary of the Company as to whether a Transfer results in a conversion to Class A Common Stock shall be conclusive and binding.

(e) Immediate Effect. In the event of a conversion of shares of Class B Common Stock to shares of Class A Common Stock pursuant to this Section 6, such conversion(s) shall be deemed to have been made at the time that the Transfer of shares occurred or immediately upon the Final Conversion Date, as applicable. Upon any conversion of Class B Common Stock to Class A Common Stock, all rights of the holder of shares of Class B Common Stock shall cease and the person or persons in whose names or names the certificate or certificates (or book-entry position(s)) representing the shares of Class A Common Stock are to be issued shall be treated for all purposes as having become the record holder or holders of such shares of Class A Common Stock.

7. Redemption. The Common Stock is not redeemable.

8. Reservation of Stock Issuable Upon Conversion. The Company shall at all times reserve and keep available out of its authorized but unissued shares of Class A Common Stock, solely for the purpose of effecting the conversion of the shares of the Class B Common Stock, as applicable, such number of its shares of Class A Common Stock as shall from time to time be sufficient to effect the

conversion of all outstanding shares of Class B Common Stock; and if at any time the number of authorized but unissued shares of Class A Common Stock shall not be sufficient to effect the conversion of all then-outstanding shares of Class B Common Stock, as applicable, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Class A Common Stock to such numbers of shares as shall be sufficient for such purpose.

9. Prohibition on Reissuance of Shares. Shares of Class B Common Stock that are acquired by the Company for any reason (whether by repurchase, upon conversion, or otherwise) shall be retired in the manner required by law and shall not be reissued as shares of Class B Common Stock.

For the management of the business and for the conduct of the affairs of the Company, and in further definition, limitation and regulation of the powers of the Company, of its directors and of its stockholders or any class thereof, as the case may be, it is further provided that:

A. Board of Directors.

1. Generally. Except as otherwise provided in the Certificate of Incorporation or the DGCL, the business and affairs of the Company shall be managed by or under the direction of the Board of Directors. The number of directors that shall constitute the Board of Directors shall be fixed exclusively by resolutions adopted by the Board of Directors.

2. Election.

(a) Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, the directors shall be divided into three classes designated as Class I, Class II and Class III, respectively. Each class shall consist, as nearly as possible, of one-third of the total number of such directors. The Board of Directors is authorized to assign members of the Board of Directors already in office to such classes at the time the classification becomes effective. At the first annual meeting of stockholders following such initial classification of the Board of Directors, the initial term of office of the Class I directors shall expire and Class I directors shall be elected for a full term of three years. At the second annual meeting of stockholders following such initial classification of the Board of Directors, the initial term of office of the Class II directors shall expire and Class II directors shall be elected for a full term of three years. At the third annual meeting of stockholders following such initial classification of the Board of Directors, the initial term of office of the Class III directors shall expire and Class III directors shall be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors shall be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting.

(b) No stockholder entitled to vote at an election for directors may cumulate votes.

(c) Notwithstanding the foregoing provisions of this section, each director shall serve until his successor is duly elected and qualified or until his or her earlier death, resignation or removal. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

(d) Election of directors need not be by written ballot unless the Bylaws so provide.

3. Removal of Directors. Subject to any limitations imposed by applicable law, removal shall be as provided in Section 141(k) of the DGCL.

4. Vacancies. Subject to any limitations imposed by applicable law and subject to the rights of the holders of any series of Preferred Stock, any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other causes and any newly created directorships resulting from any increase in the number of directors, shall, unless the Board of Directors determines by resolution that any such vacancies or newly created directorships shall be filled by the stockholders and except as otherwise provided by applicable law, be filled only by the Board of Directors by a majority of the directors then in office, although less than a quorum, or by the sole remaining director, and not by the stockholders. Any director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the director for which the vacancy was created or occurred and until such director’s successor shall have been elected and qualified.

5. Preferred Directors. Notwithstanding anything herein to the contrary, during any period when the holders of any series of Preferred Stock, voting separately as a series or together with one or more series, have the right to elect additional directors, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Company shall automatically be increased by such specified number of directors, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions; and (ii) each such additional director shall serve until such director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, resignation, retirement, disqualification or removal. Except as otherwise provided by the Board of Directors in the resolution or resolutions establishing such series, whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of such stock, the terms of office of all such additional directors elected by the holders of such stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate and the total authorized number of directors of the Company shall be reduced accordingly.

B. Stockholder Actions. No action shall be taken by the stockholders of the Company except at an annual or special meeting of stockholders called in accordance with the Bylaws and no action shall be taken by the stockholders by written consent. Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the Company shall be given in the manner provided in the Bylaws of the Company.

C. Bylaws. The Board of Directors is expressly empowered to adopt, amend or repeal the Bylaws of the Company. The stockholders shall also have power to adopt, amend or repeal the Bylaws of the Company; provided, however, that, in addition to any vote of the holders of any class or series of stock of the Company required by law or by the Certificate of Incorporation, such action by stockholders shall require the affirmative vote of the holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of the capital stock of the Company entitled to vote generally in the election of directors, voting together as a single class.

VI.

A. The liability of the directors of the Company for monetary damages for breach of fiduciary duty as a director shall be eliminated to the fullest extent permitted under applicable law.

B. To the fullest extent permitted by applicable law, the Company may provide indemnification of (and advancement of expenses to) directors, officers, and other agents of the Company (and any other persons to which applicable law permits the Company to provide indemnification) through Bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise.

C. Any repeal or modification of this Article VI shall only be prospective and shall not affect the rights under this Article VI in effect at the time of the alleged occurrence of any action or omission to act giving rise to liability.

D. Unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (A) any derivative action or proceeding brought on behalf of the Company; (B) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any current or former director, officer or other employee of the Company or any stockholder to the Company or the Company’s stockholders; (C) any action or proceeding asserting a claim against the Company or any current or former director, officer or other employee of the Company or any stockholder arising pursuant to any provision of the DGCL, the Certificate of Incorporation or the Bylaws of the Company (as each may be amended from time to time); (D) any action or proceeding to interpret, apply, enforce or determine the validity of the Certificate of Incorporation or the Bylaws of the Company (including any right, obligation or remedy thereunder); (E) any action or proceeding as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; and (F) any action asserting a claim against the Company or any director, officer or other employee of the Company or any stockholder, governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. This Article VI shall not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934 or any other claim for which the federal courts have exclusive jurisdiction.

E. Unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, subject to and contingent upon a final adjudication in the State of Delaware of the enforceability of such exclusive forum provision.

F. Any person or Entity holding, owning or otherwise acquiring any interest in shares of capital stock of the Company shall be deemed to have notice of and to have consented to the provisions of this Article VI.

VII.

A. The Company reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, except as provided in paragraph B. of this Article VII, and all rights conferred upon the stockholders herein are granted subject to this reservation.

B. Notwithstanding any other provisions of this Certificate of Incorporation or any provision of law that might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote required by law or by this Certificate of Incorporation, the affirmative vote of the holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of capital stock of the Company entitled to vote generally in the election of directors, voting together as a single class, shall be required to alter, amend or repeal Articles V, VI, and VII.
