Engineers ship with A.I. Builder

What they said after the first sprint.

Priya Nambiar

Solo Founder, Stackr.io

"I shipped my MVP in 11 days. A.I. Builder wrote every data layer — models, migrations, tests. I just connected the dots."

Marcus Webb

Backend Lead, Torchlight (Series A)

"We cut sprint boilerplate by 60%. A.I. Builder handles the CRUD scaffolding and I review the diff. Four seconds versus four hours."

Caitlin O'Reilly

Agency Dev, Brightline Studio

"Six client repos, one engineer. A.I. Builder is the only reason I hit my Friday deadline. The test coverage alone saves me two hours a sprint."

Dev Anand Krishnan

Staff Engineer, Finloop

"The diff quality is uncanny. I ran it against our senior engineer's Postgres query layer — 94% structural match, 31% fewer lines."

Sofia Mendez

Platform Engineer, Cloudnova

"A.I. Builder is the first codegen tool that ships tests I actually trust. The branch coverage is consistently above 95%."

James Okafor

Tech Lead, BuildBase

"I gave it our internal naming conventions in a system prompt. Every output since has matched our style guide without me touching a line."
