“Honestly, I don’t know what Spartan is feeding their engineers, but they’re ridiculously good and stupid fast - specs today, in prod tomorrow, lol!”
VC FOUNDER
"They hit every deadline, pivot on a dime, and keep it low-touch and async. Whether flying solo or with guidance, they crush it either way.”
US STARTUP CTO

How We Work

We don't act like contractors — we embed as part of your team. With agile pods, async standups, and trunk-based development, we move fast and build like founders.

Coffee chat
MVP is live
Team is up to speed

Engineering Practices

Async standups (Slack) – lightweight daily updates, zero wasted time
Agile (Scrum/Kanban) – clear priorities, fast iteration
PRDs & RFCs – align quickly, then go build
Code reviews – every PR reviewed to keep quality high

Delivery Pipeline

Continuous Deployment
Ship features to both dev/prod multiple times a week
Automated Testing
CI checks, integration & regression coverage
Monitoring
Real-time metrics, alerts before issues hit users

Reliability & Support

On-call rotation – engineers handle P0/P1 alerts, rollback if needed
Post-mortem & learnings – RCA, no blame, just improving systems
Feature flags & toggles – safe rollouts, instant fallbacks

We Build. You Raise.

They didn't just ship apps — they raised capital. Our work turned into checks, not chatter.
