We build software.
Then we sell it
Four flagship products live and paying. Plus a few more we run for ourselves. All built for problems we had first - and each one runs on the same stack we would use to build yours.
Eddi
AI content management for Umbraco. Chat with your site, audit in bulk, installed as a NuGet package.
Sumlo
Timesheets from Toggl, Harvest and Clockify, turned into branded PDF client reports. Built in a long weekend.
Patch
A UK gardening companion with 382 crops, weather-aware tasks, and a visual bed planner. iOS and web.
Printo
HTML to PDF API with three-layer caching, cloud storage, and a NuGet package for ASP.NET Core.
Concepts we have built for ourselves.
Not everything we build becomes a product. Some of it stays internal because the audience is too small, or because we are the audience. We show it here because it demonstrates the rapid-development capability we sell to clients.
Why we ship our own products.
Infrastructure reuse
Every product shares the same hosting, the same deployment pipeline, the same observability. Building the fourth product is cheaper than building the first because the engine is already there.
Client trust
Clients who hire us for rapid development can see the products we've shipped with the same method. No pitch deck beats a live product page with a working checkout.
Recurring revenue
Products pay monthly. Services pay per project. A product portfolio smooths the cashflow that a pure-agency model makes lumpy.
Want us to build you something like this?
Every product here was built using the same service we sell: Rapid Development. If you have an idea that is already solving a real problem, either for you or for customers who keep asking, we will turn it into a working product in weeks.

Simplepage is a software company on the Isle of Man with four flagship products live and paying: Eddi (AI content management for Umbraco), Sumlo (timesheets turned into branded PDF client reports), Patch (a UK gardening companion with 382 crops), and Printo (an HTML-to-PDF API). A fifth, Pulse, is the internal project management and client portal we run the agency on. Every product was built for a problem we had first, and each runs on the same stack we would use to build yours.
Simplepage ships its own products for three reasons. Infrastructure reuse: every product shares the same hosting, deployment pipeline and observability, so the fourth product is cheaper to build than the first. Client trust: clients hiring us for rapid development can see live products shipped with the same method - no pitch deck beats a working checkout. Recurring revenue: products pay monthly, which smooths the lumpy cashflow of a pure-agency model.
Yes. Every product on this page was built using the same service we sell: Rapid Development. If you have an idea that is already solving a real problem - for you, or for customers who keep asking - we will turn it into a working product in weeks, on .NET 10 and the same stack our own products run on. Send a paragraph describing it and we'll tell you what it would take.
Four Simplepage products are live commercial services: Sumlo (sumlo.io), Patch (my-patch.app) and Printo (printo.im) are fully live, and Eddi (eddi.im) is live in beta. Pulse is internal - a Trello-style project management tool with Toggl time tracking that we built to run the agency on our own stack. We show it because it demonstrates the rapid-development capability we sell to clients.
Simplepage products run on .NET 10 with Razor views, alongside the tools each product needs: Umbraco 13 and 17 plus the Anthropic Claude API for Eddi, the Toggl API for Sumlo and Pulse, Puppeteer and Azure Blob storage for Printo, and a PWA with the Met Office API for Patch. They share one hosting setup, one deployment pipeline and one observability stack - the same stack we use for client builds.
