How We Work
Our process, from brief to launch
01
Discovery (1–2 weeks)
We map workflows, systems, and constraints before any production code.
02
Design & architecture (2–3 weeks)
Clickable prototypes, integration plan, and a transparent build roadmap.
03
Agile build (6–16 weeks)
Weekly demos and working software every sprint.
04
Launch & iterate (ongoing)
Migration, QA, go-live support, then a living maintenance cadence.
Social Proof
Integration discipline
MLS work succeeds when feed rules are designed in — not patched after launch.
“Foundrex came on board to rescue my SaaS project when the original dev team abandoned the work. They refactored the code, fixed system gaps, and pulled the project back online. I'd highly recommend them to ship your product.”
