A platform has an audience beyond your own team. Clients log in, customers book, suppliers submit. That changes the work. Anything outside your organisation has to hold up in front of people you have never met, which an internal tool never has to do.
We start with the smallest version that people can actually use, and build that properly. Accounts, permissions, payments and the admin side are done right the first time, so the second version builds on the first rather than replacing it.
Subscription tools built for a specific industry or problem. Separate accounts for each customer organisation, sign-in and billing built in.
Online booking with availability management, payment, automatic confirmations and an admin dashboard for your team.
Gated communities, subscription content, online courses and member directories, with payment, access control and messaging built in.
Somewhere your clients log in to see their documents, progress and invoices, instead of asking your team by email.
Two-sided platforms connecting buyers and sellers, with listings, search, messaging and payment handling.
Features powered by Claude, such as drafting content, searching in plain English or processing uploaded documents.
Kismet is a UK wedding planning platform we are building. It has guest management, a seating planner that spots conflicts, a budget tracker and tools for suppliers. The waitlist is open and the platform is being built. We also run Retention Manager and Margin Manager, two paid products on this site with sign-in, organisation accounts and Stripe billing.
See the products we run →Platforms start at £850, and most land between £1,500 and £3,500. A typical first version takes around ten weeks.
The biggest driver is how many distinct types of user there are. Each needs its own screens, plus the permissions logic that decides who sees what, and that logic is where most of the cost sits. The number of outside systems it connects to comes next.
The price is fixed in writing before we start. Hosting is separate and paid straight to the provider, usually somewhere between £40 and £120 a month for a platform.
For a figure without a call, the build estimator itemises one in two minutes.
Nothing is paid up front. You watch the finished thing work with your own data, and only then do you pay. No deposit and no retainer. How the process works →
A platform has an audience beyond your own team. Clients log in, customers book, suppliers submit. That changes the work considerably, because anything outside your organisation needs to be reliable, presentable and secure in a way an internal tool does not.
From £850, and most land between £1,500 and £3,500. The cost is driven by how many distinct types of user there are, since each needs its own interface plus the permissions logic behind it, and by how many external systems it has to connect to.
Around ten weeks for a typical first version. A simple booking system can be quicker, and a platform with several user types and integrations takes longer. The timeline is agreed with the fixed price before we start.
Yes. The code, the domain, the hosting account and the documentation. Nothing sits behind a licence you have to keep paying for, and nothing depends on us being reachable in two years.
Nothing is paid up front. You watch the finished platform working with your own data, and only then do you pay the agreed price.
You own the code and the documentation, so any competent developer can pick it up. We quote new features separately rather than selling a retainer.
