QA & Deployment
Testing built into every sprint, then CI/CD-driven release.
Maintenance & Support
A post-launch support window with the same engineers who built it.
Everything You Need to Know Before You Hire.

A focused internal tool typically runs $20,000–$50,000, while a full enterprise platform with multiple integrations can run $150,000+. We scope against your actual requirements after a discovery call.
A focused MVP typically takes 8-12 weeks. A full enterprise platform with multiple integrations usually runs 20-30 weeks.
Senior engineers who stay accountable through delivery and support, a clear architecture rationale, and real client references — not just a portfolio of logos.
We work in two-week sprints specifically so scope changes are absorbed at a sprint boundary, not treated as a change-order crisis.
Our teams work from our London and Austin, Texas offices and serve Illinois clients remotely with full Central-time overlap.
