Real problems, solved properly.

We design and build websites, web apps and phone apps for UK small businesses, starting from the problem you actually have.

Problems we’ve solved

Three real products, each built to solve a real problem.

The problem: Money for a shared project gets spent from different cards, accounts and currencies, and nobody can say who owes whom.

CoManTra Invite-only beta

Simple to use and quick to enter, built for the phone in your hand.

Easy data entry: quick add, voice entry, and the full form saves even without a category.
Scan and go: photograph a receipt or bill and AI reads it for you: payee, items, amounts.
Statement upload: bank statements (CSV, OFX, Excel, PDF) read by AI and matched to your entries automatically.
Share from other apps: send a receipt or statement straight from your banking app, email or photos.
Works offline: entries are kept on the phone and sent when the signal returns.
If one AI service is busy, another takes over, so nothing waits.
Exact splits, balances and settlements in 27 currencies.

The problem: Homeowners can't tell what solar or a battery would really save them, so they don't ask.

GenNext Power

An energy check built on the home's own meter data.

Detailed energy usage analysis, as fine-grained as it gets: the home's real half-hourly smart meter readings.
Automated analysis spots car charging, washing and dishwasher runs, heating and the always-on load, and reads tariff rates from a bill inside the browser.
Return on investment worked out from facts, not assumptions: a better deal, a night tariff, a battery, then solar, each from the home's own usage.
An enquiry form that saves and emails every enquiry.

The problem: A refurbishment company needed to show what it does to a room, not just list trades.

Scroll-driven rooms that turn from bare shell to finished as you scroll.
An enquiry form with photo upload that emails each enquiry.

What we build

Websites

Fast, clear sites that turn visitors into enquiries, and that you can keep up to date.

Web apps

Tools your team uses every day in a browser: bookings, quotes, records, reports.

Phone apps

Apps that work in the hand, on the move, even without signal.

AI and data

Cutting-edge AI that reads receipts, statements and documents, turns messy data into answers, and saves typing.

We work with the newest AI models and tools, and use them where they genuinely save time, not for show.

Nearly two decades of building software.

Platinum has been designing and building software for close to twenty years. That is a generation of experience in what works, what lasts and what people actually use, now put to work with today’s newest tools.
