Most of your app already exists. We build the part that doesn't.

We have already built and run the parts every business app needs: sign-in and permissions, multi-tenancy, dashboards, workflows that can't drop, WhatsApp and USSD. Your project starts on top of that instead of an empty repo, so it ships in weeks. Fast because the groundwork is done, not because we skip it.

Why it takes weeks, not months

We spent years building a framework and the tools around it for the parts every business app repeats, and we run them in production every day. That platform is the head start. When you hire us, the foundation is already built and tested, so we spend our time on the logic specific to your business, the part no framework ships with. Six months of groundwork becomes a few weeks of focused work.

What we build

Internal tools and CRMs

The systems a business runs on. Pipelines, back-office workflows, reporting, approvals. Software your team operates from every day, not a demo.

WhatsApp and USSD products

Order flows, balance checks, agent data collection, surveys. USSD reaches feature phones and works with no data, which matters when your customers are traders, field agents, or rural.

Integrations that don't break

Payment reconciliation, multi-step onboarding, scheduled follow-ups, retries against flaky third-party APIs. Long-running processes with real delivery logs, not hand-rolled cron.

The unique 20 percent

Whatever your business actually does that no one else does. That is where we spend our time, because everything underneath it is already built.

Products we run

We build our own products on the same platform. When one fits your problem, you get it live on day one instead of paying us to rebuild it.

FLAGSHIP

Multi-channel support and messaging: a shared inbox, AI-drafted replies, and a knowledge base your bot answers from. One place for WhatsApp, web, and more.

The stack we build on

This is the platform. It is open source, and we maintain it in the open. It is also why a build that would normally take six months takes a few weeks.

Convention-driven Rails framework for full business applications, with authorization and UI built in.
Conversational interfaces for WhatsApp, Telegram, and USSD, with interactive flows.
Durable, distributed workflows for Rails that survive restarts and retry safely.
Outbound webhooks with signing, retries, and SSRF protection.
ActiveStorage-compatible attachments backed by Shrine.
Component suite for building Rails UIs in Ruby.

Who we are

Radioactive Labs is the studio of Stefan Froelich, who built a Ghanaian fintech from zero to 580,000 users and helped scale a mental health platform to 25 million covered lives. Small team, senior hands, no handoff to juniors.
