A few minutes that save you a bad decision.
Ego Eimi publishes seven free tools for owners deciding on custom software: an ROI calculator, a cost estimator, a build vs buy quiz, a security self-check, a scope template, a developer vetting checklist, and a tech due-diligence scorecard. None needs a signup or an email, and each runs in your browser in a few minutes.
01 / Start anywhere
Each tool answers one money question, with no commitment.
They are quick on purpose, and the same questions sit behind our paid work. When you want a human read on the numbers, our audit turns any of these into a concrete plan backed by a written value guarantee, and you can always see the full services first.
