REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM




Shareholders and Board of Trustees
Renaissance Capital Greenwich Funds
Greenwich, Connecticut

In planning and performing our audits of the financial
statements of The Global IPO Fund, the Renaissance
IPO ETF and the Renaissance International IPO ETF,
each a series of shares of Renaissance Capital
Greenwich Funds ("the Trust"), as of and for the year
ended September 30, 2017, in accordance with the
standards of the Public Company Accounting Oversight
Board (United States), we considered their internal
control over financial reporting, including control
activities for safeguarding securities, as a basis for
designing our auditing procedures for the purpose of
expressing our opinion on the financial statements and to
comply with the requirements of Form N-SAR, but not
for the purpose of expressing an opinion on the
effectiveness of the Trust's internal control over
financial reporting.   Accordingly, we express no such
opinion.

The management of the Trust is responsible for
establishing and maintaining effective internal control
over financial reporting.   In fulfilling this responsibility,
estimates and judgments by management are required to
assess the expected benefits and related costs of controls.
A company's internal control over financial reporting is
a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the
preparation of financial statements for external purposes
in accordance with generally accepted accounting
principles.   A company's internal control over financial
reporting includes those policies and procedures that (1)
pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in
accordance with generally accepted accounting
principles, and that receipts and expenditures of the
company are being made only in accordance with
authorizations of management and directors of the
company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized
acquisition, use or disposition of a company's assets that
could have a material effect on the financial statements.

Because of inherent limitations, internal control over
financial reporting may not prevent or detect
misstatements.   Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in
conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

A deficiency in internal control over financial reporting
exists when the design or operation of a control does not
allow management or employees, in the normal course
of performing their assigned functions, to prevent or
detect misstatements on a timely basis.   A material
weakness is a deficiency, or combination of deficiencies,
in internal control over financial reporting, such that
there is a reasonable possibility that a material
misstatement of the company's annual or interim
financial statements will not be prevented or detected on
a timely basis.






Our consideration of the Trust's internal control over
financial reporting was for the limited purpose described in
the first paragraph and would not necessarily disclose all
deficiencies in internal control that might be material
weaknesses under standards established by the Public
Company Accounting Oversight Board (United States).
However, we noted no deficiencies in the Trust's internal
control over financial reporting and its operation, including
controls for safeguarding securities, which we consider to
be material weaknesses, as defined above, as of September
30, 2017.

This report is intended solely for the information and use of
management, Shareholders and Board of Trustees of
Renaissance Capital Greenwich Funds and the Securities
and Exchange Commission, and is not intended to be and
should not be used by anyone other than these specified
parties.
