The following table summarizes the computation of basic and diluted net loss per share attributable to common stockholders of the Company:

	Year ended December 31,
	2021			2020
Numerator:
Net loss	$	(85,805	)	$	(52,243	)
Denominator:
Weighted-average number of common shares, basic and diluted		36,739,269			33,488,456
Net loss per share, basic and diluted	$	(2.34	)	$	(1.56	)

The Company’s potential dilutive securities, which include common stock options and ESPP purchase rights, have been excluded from the computation of diluted net loss per share as the effect would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same.

The Company excluded the following potential common shares, presented based on amounts outstanding at period end, from the computation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect:

	December 31,
	2021		2020
Outstanding options to purchase common stock		5,435,304		4,454,424
