Solwen Studios
A booking platform for three pilates studios: class schedules, waitlists, memberships and a front-desk check-in view.
+34%online bookings in the first term after launch
Web apps that pull their weight.
We're a seven-person studio in Bristol that designs, builds and looks after web apps, brand sites and design systems. Carefully considered, sturdily engineered work from the team behind forty-six launched products and two design systems in daily use.
Web apps
Booking, billing and internal tools on a stack your own team can keep shipping on.
Brand sites and shops
Fast marketing sites and stores your marketers can edit without filing a ticket.
Design systems
Tokens, components and docs that keep three products looking like one.

“Wrenfold turned a spreadsheet of class times into a booking app our members actually like. Online bookings went up by a third in the first term.”
Recent work
Four launches from the last eighteen months, with the numbers our clients agreed to share.
Tillery
Invoicing and payouts for independent studios. We rebuilt the invoice composer, payment links and reminders that chase late payers.
2 minmedian time to send an invoice, down from seven
Halde Coffee
A brand site and subscription shop for a roastery that had only ever sold wholesale. Pause, skip and swap a bag in two taps.
1,180active subscriptions six months after launch
Velomar
One design system for a city bike-share network: the rider app, the docking kiosks and the operations dashboard.
42components in code, used by three product teams

Two mobile projects are in the archive below. Most mobile work sits behind client agreements, so we walk through it on a call instead.

“They ran our design system like a product, with a roadmap, a changelog and weekly office hours. Three teams now ship from the same components.”
We handle just about everything
From the first workshop to the hundredth deploy, one team carries the work. No hand-offs between agencies, no lost context.
-
Product design
Research, flows and interface design, tested with real users before anyone writes production code.

Web app development
TypeScript front ends and sturdy APIs, built so your own engineers enjoy picking them up later.
Usually 8 to 14 weeksAsk -
Brand sites and shops
Marketing sites and stores with a CMS your team can run. Fast on a phone, findable in search.

How a project runs
Short cycles, a demo every Friday and one shared board. You always know what shipped this week and what is next.
-
Weeks 1 to 2
Discover
Workshops with your team, interviews with five to eight customers and a look at the numbers you already have. We agree what success means before we draw anything.
- Written brief
- Clickable prototype
- Fixed quote for the build
-
Weeks 2 to 6
Design
Flows first, then interface. Every screen is tested with real users and reviewed with your engineers so nothing arrives that cannot be built.
- Design files you own
- Usability test notes
- Component inventory
-
Weeks 5 to 12
Build
Design and engineering overlap. You get a staging link on day one of the build and a recorded demo every Friday.
- Weekly demos
- Staging from day one
- Code in your repository

Questions from first calls
If yours is not here, ask it in the form below. A designer or engineer answers, not a sales team.
Ask a questionWe book about eight weeks ahead. Our next build slot opens in February 2027, and a two-week discovery sprint can usually start within three weeks of a first call.
Most product builds land between £48,000 and £110,000. A discovery sprint is a fixed £12,500 and ends with a fixed quote, so you never sign up for an open-ended number.
Often. We pair with your engineers, work in your repository and follow your review process. Half of our projects end with a handover to a team we helped hire.
You do, from the first commit. Code lives in your repository and design files in your workspace. We keep nothing back and charge no licence fees.
Usually TypeScript with a React framework, Postgres and a headless CMS for content-heavy sites. If you already have a stack and a team, we build in it.
No. About half of our clients are elsewhere in the UK and Europe. We travel for discovery workshops and launches and work remotely in between.

We reply within one working day with honest next steps, even when we are not the right fit. You saw the testimonials, right?
