We design, build, and ship complete software products — multi-tenant SaaS, web and mobile apps, and the platforms behind them — engineered to be reliable, secure, and ready to grow with you.
Plenty of teams can build a feature. Far fewer can take a vision and ship the whole product — architecture, frontend, backend, payments, infrastructure, and the operational polish that makes it dependable day after day.
That's what GMK does. We've built and run production platforms like Sahasra (an operating system for community organizations) and Paddle Play (an AI-powered sports platform) end to end — multi-tenant, payment-processing, real-time systems that people rely on every day.
Secure, tenant-isolated architectures that serve many organizations from one product — the backbone of a real SaaS.
Fast, modern, branded apps built with React/TypeScript and native-quality mobile — designed to convert, built to last.
Stripe Connect, subscriptions, marketplace payouts, and the financial plumbing that has to be exactly right.
Calendars, bookings, on-site kiosks, and live updates — the operational features that run a business.
Turn an idea into a real, launch-ready product — MVP to scale — without building a whole team first.
Multi-tenant systems that run an organization end to end: payments, scheduling, members, and more.
Build it once and offer it to your own clients under your brand.
