Net loss per share attributable to common stockholders—basic and diluted	$	(0.57)	$	(0.59)	$	(1.08)

The Company’s potentially dilutive securities, which include outstanding stock options and restricted stock units, and in prior years redeemable convertible preferred stock, and warrants to purchase shares of common stock, have been excluded from the computation of diluted net loss per share from each period as including them would have had an anti-dilutive effect. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potentially dilutive securities for each period presented:


	Year Ended December 31,
	2023	2022	2021
Options to purchase common stock	3,831,710	4,034,287	3,949,943
Restricted stock units	3,400,489	2,807,981	309,530
