The problem
Every engineering team has the same 3 doc problems
And they cost more than you think.
Docs don't exist
Engineers hate writing documentation. It always gets deprioritized. New hires spend weeks just reading code trying to understand what does what.
Docs go stale fast
Even when docs exist, they're wrong within weeks. Code changes, docs don't. Developers stop trusting them and stop reading them entirely.
Onboarding is expensive
Every new engineer hire takes 4–8 weeks to become productive. No good docs is the #1 reason. That costs companies ₹8–25 lakh per hire in lost productivity.
The ROI math
New hire ramp time
6 weeks
