What we built

Costtrail co-built a B2B SaaS platform on AWS with React, Next.js, and Bedrock-powered onboarding. Engaged on a partnership model — revenue share kicks in at first paying cohort.

Costtrail engaged on a partnership basis across 3 pillars — Cloud Engineering, AI / GenAI Engineering, Product Engineering. Delivered in 2-week sprints with weekly demos, eval-gated deploys, and quality checks at every milestone. Code, infrastructure, and operations were handed back to the client team at close, with optional 24/7 SRE support after launch.
