The challenge
Apex HR had product-market fit but a fragile monolith. Releases were monthly, risky and often rolled back.
Hiring senior engineers locally was taking six months per role.
The solution
A dedicated Watsbit team of 11 joined in two weeks, modularised the monolith, introduced automated testing and moved releases to daily.
The same team now ships the roadmap alongside Apex's in-house engineers.
“It doesn't feel like outsourcing. The Watsbit squad owns outcomes exactly like our own engineers do.”— VP Engineering, Apex HR
