	Three months ended October 31,						Nine months ended October 31,
	2019			2018			2019			2018
Numerator:
Net loss	$	(2,437	)	$	(4,172	)	$	(16,625	)	$	(9,983	)
Preferred stock dividend paid		—			—			(14,955	)		—
Accretion of redeemable convertible preferred stock to redemption value		—			(9,236	)		(56,175	)		(20,962	)
Net loss attributable to common stockholders	$	(2,437	)	$	(13,408	)	$	(87,755	)	$	(30,945	)
Denominator:
Weighted-average shares of common stock outstanding, basic and diluted		35,790,951			1,909,858			15,007,247			1,176,833
Net loss attributable to common stockholders	$	(0.07	)	$	(7.02	)	$	(5.85	)	$	(26.30	)

The Company’s potential dilutive securities, which include Convertible Preferred, stock options, restricted stock units and outstanding warrants to purchase shares of common and preferred stock, 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:

	October 31, 2019		October 31, 2018
Redeemable convertible preferred stock (as-converted to common stock)		—		25,311,535
Stock options to purchase common stock and restricted stock units		6,645,106		5,094,108
Warrants to purchase convertible preferred stock		—		581,798
Warrants to purchase common stock		228,178		256,411
		6,873,284		31,243,853
