We build the software
your business can't buy.
Zeraio designs and ships custom software for small and medium teams who have outgrown their spreadsheets, hacks, and off-the-shelf tools. Two founders, one room, one tool that fits.
A small studio for serious software.
Zeraio is a two-person studio: one engineer, one business lead. We embed for 8 to 16 weeks, write production code from day one, and hand over a system your team can actually run. No agency layers, no offshoring, no discovery decks that go nowhere.
Replace the patchwork. The four SaaS subscriptions, the brittle spreadsheets, the Zapier maze. We build one piece of software that fits the way our clients actually work. Bespoke, owned outright, calm to operate.
Small and medium businesses run the real economy. They deserve software designed for them, not enterprise tools rebranded with a free tier. We are building a future where bespoke software is as accessible as a good accountant.
Six things, done properly.
We deliberately keep the menu short. Tap any service to see how we approach it. Every line is work we do ourselves, end to end — no agency layers, no white-labelled vendors.
The thing your business needs that does not exist as a SaaS. We scope it, design it, build it, and ship it. You own the code from day one.
