How they think
“A model is a decision you can measure, not magic you trust.”
NajiUllah's first principle
Off the record
- 01
Reads eval reports like novels
- 02
Breaks LLMs for fun, then fixes them
regulated · secure by default
One senior, still fully accountable.
Even when you work one-on-one, the studio holds the line behind them. We vet, contract, and regulate everyone on the floor - so you get the speed of an individual with the safety of a company.
Under studio contract
No stranger with a laptop. Every person on your build is vetted, retained, and accountable to Breakthrough Pulse - not a marketplace handle.
IP assigned in writing
Ownership lands with you on paper before code moves. No ambiguity, no hidden claims, no hostage codebases.
NDA from day zero
Your idea is covered before the first conversation goes deep. Signed, mutual, and on file.
Regulated, receipts included
Work runs in the open with dated commits, deploy logs, and readouts you can verify yourself.

Off the clock
- Prompting until it behaves

- Agent experiments that break then work
