You have no idea what your startup costs
Forgotten subscriptions and invisible hours add up. StackTracker counts every one and tells you: keep going or kill it.
The problem
Is your startup actually profitable?
Most solo founders can't answer. The costs live in ten dashboards, and the biggest cost, your time, lives in none.

Seven tools keep billing you. Two you haven't opened since March.
of your life, billed to nobody
At €60 an hour that's €14,460 of invisible cost. No bank statement will ever show it.
real ROI, once your time counts
Cash says +11%. Your hours say otherwise. That's the number you decide with.
Numbers from six months of a real side project, measured cold.
