We turn bold ideas into software that ships
Rainbow Soft is a senior development team for founders and growing companies. We build MVPs, full-stack platforms, mobile apps and AI-powered products, end to end.
A small senior team that builds like co-founders, not contractors.
We partner with founders and growing companies to design, build and scale software: SaaS platforms, internal tools, mobile apps and AI-powered products.
- You work directly with the engineers writing your code
- Weekly demos and a shared roadmap, so nothing is hidden
- Production-grade from day one: tested, monitored, documented
Everything you need to go from idea to scale
Eight ways we help teams ship. Pick one, or let us combine them into a single engagement.
Products we've shipped
Internal platforms, live-commerce marketplaces, booking engines and mobile apps that are live and in use.
A clear process, no surprises
Five steps that take your product from a conversation to a launched, growing business.
- 01
Discovery
We dig into your goals, users and constraints, then turn them into a prioritized scope, timeline and budget.
- 02
Design
We map user flows and build clickable Figma designs, so you see and test the product before we write code.
- 03
Build
We work in short, transparent sprints with weekly demos, so you always know what shipped and what's next.
- 04
Launch
We handle QA, deployment, app-store releases, monitoring and analytics, and launch day goes smoothly.
- 05
Support
After launch we keep improving: fixes, new features, scaling and performance tuning as you grow.
The right tool for every layer of your product
Battle-tested technology we know deeply, chosen for your product's needs rather than for hype.
