Stackwise

The problem

Companies with 100 staff pay for around 120 software tools, a third of them unused, and nobody owns the list or the renewals.

The solution

Stackwise reads the accounts and single sign-on logs, shows every subscription with its real usage, and cancels or downgrades in one click.

Who it's for

Finance and IT leads at companies with 50–1,000 employees.

Market

Bottom-up: about 120,000 customers like this in Netherlands and nearby, worth roughly $120 million a year at our prices.

Competition and edge

Headline metric

960 active users, growing 21% a month

The team

Sanne knows the customer and has sold to them before; Tomás has built this kind of system at scale. We have worked side by side since before Stackwise had a name.

Worked together

1–3 years

Hiring

A senior engineer and our first customer-success hire.
