Our services
One team, from strategy to production.
We embed senior engineers, put frontier AI behind them, and ship working software in weeks, so you get a number that moved instead of a roadmap.
Why realfast
We adopt every frontier model the day it ships, put senior engineers behind it, and leave you owning the software, not renting a black box.
How we work
Discovery to production, in weeks.
Discover
Agents index your systems and map the work from the first sprint. On one platform rebuild, the technical analysis internal teams had scoped at one to three months landed in under a week.
Build
Human plus AI teams: we delegate to agents what agents do best and keep senior engineers on the judgment. Every prompt is regression-tested against your real data before go-live.
Ship
Working software in production, and the system stays yours to change. 4.5 weeks for fintech case triage, 5 for Z47's investment committee, 10 to extend a platform into a new market.
Have a deadline in mind? Let's pressure-test it.
