We Build Software — Not Just Websites

Steony is half design studio, half software house. We run our own software products, and we build custom platforms for clients — multi-tenant SaaS, AI phone systems, vehicle-lookup portals and mobile apps. We'll build the same calibre of software for your business.

Built, Owned & Run In-House

Our Own Software Products

The best proof that we can build real software is the software we run ourselves. Each of these is a live product we designed, built, own and maintain.

AI Answerphone

A multi-tenant AI voice answering platform. It picks up calls in a natural-sounding voice, answers common questions, captures the caller's details and routes or books the enquiry — a 24/7 receptionist that never misses a lead.

AI Voice SaaS Telephony Multi-tenant

Call2SMS

Missed-call recovery for busy businesses. The moment a call is missed, Call2SMS texts the caller back and holds a two-way AI conversation to capture the lead before it goes cold. Built on Asterisk and AI.

VoIP Asterisk AI SMS Lead Capture

Weightlytic

A weight-loss tracking and forecasting app. It forecasts your goal date from your trend data, analyses meals from a photo, and includes companion tools for GLP-1 medications. Built with React Native. (Launching soon — waitlist open.)

Built For Clients

Custom Software We've Built for Clients

We don't only build for ourselves. These are full software platforms we designed and developed for clients — owned and run by them, engineered by us.

RemappingWebsite.com

A multi-tenant vehicle remapping platform built for a client. Drivers enter their registration and instantly see the tuning gains available for their exact vehicle, while tuning businesses get their own white-label portal to manage quotes, customers and remap files.

UKLPA

A UK-compliant Lasting Power of Attorney service built for a client. A guided, multi-step platform that walks people through creating their LPAs correctly under the Mental Capacity Act 2005.

For Your Business

The Same Engineering, Built for You

Need more than a website? We build custom software around your workflow — from a single admin dashboard to a full multi-tenant SaaS product you can sell.

Admin Dashboards & Portals Custom control panels and customer/staff portals to run your business from one screen.

Database-Driven Web Apps CRMs, booking systems, inventory and quoting tools built around your exact workflow.

Multi-tenant SaaS Platforms White-label products with per-client accounts, billing and isolation — like our own platforms.

API Integrations Connect to DVLA, payment gateways, CRMs and third-party services so your tools talk to each other.

AI Integration AI voice, chat and automation built in — the same tech behind AI Answerphone and Call2SMS.

Mobile Apps Cross-platform iOS & Android apps with React Native, backed by a proper API.

Our Process

From Idea to Live Software

The same path we take with our own products — clear scope, working software early, no surprises.

Scope

We map out exactly what the software needs to do, who uses it, and what success looks like.

Architect

We design the database, data model and APIs so the system is secure, fast and built to scale.

Build

We build in stages and show you working software early, so you steer it as it takes shape.

Launch & Support

We deploy, monitor and maintain it — the same way we keep our own products running.
