	Fiscal years ended January 31,
	2023		2022		2021
Numerator:
Net loss	$	(176,146)	$	(118,161)	$	(27,292)
Denominator:
Weighted-average shares of common stock outstanding, basic and diluted	52,440,067		49,888,436		39,519,640
Net loss per share attributable to common stockholders	$	(3.36)	$	(2.37)	$	(0.69)

The Company’s potential dilutive securities, which include stock options, restricted stock units, performance stock awards, and grants under the Company's ESPP, our employee stock purchase plan, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. 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 following potential common shares, presented based on amounts outstanding at each period end, were excluded from the calculation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:


	Fiscal years ended January 31,
	2023	2022	2021
Stock options to purchase common stock, restricted stock units and performance stock awards	6,745,591	5,632,823	5,406,004
Employee stock purchase plan	74,685	75,370	—
