01What we build
Five things, done properly, instead of everything.
We are a studio, not an agency: the people who scope your project are the people who write the code. Most engagements combine two or three of these.
- 01
Marketing sites
Hand-built pages, never a page builder.
Your team edits copy and swaps images in a headless CMS, and nothing about the layout breaks when they do. Static by default, so the page is already on the CDN before anyone asks for it.
- Headless CMS
- Edge rendering
- Copy workshops
- 02
Web applications
Dashboards, portals, booking flows, internal tools.
Auth, roles, audit trails, billing, the CSV export somebody will ask for in month four — the unglamorous three quarters of an app, done properly the first time.
- Postgres
- Stripe & billing
- Role-based access
- 03
Design systems
One documented set of components.
We build the eleventh page for a fraction of what the second one cost, because the buttons, tables, and empty states were settled early and written down.
- Component library
- Tokens
- Usage docs
- 04
Performance rescues
We inherit slow sites and make them quick.
Across nine rescue engagements last year we cut a median 3.1 seconds off largest contentful paint, mostly by deleting things. You get the audit even if you never hire us for the fix.
- Core Web Vitals
- Bundle surgery
- Caching
- 05
Ongoing care
A retainer that is a person, not a ticket queue.
Two of us stay on your Slack after launch. Dependency updates, small features, the 2 a.m. page when checkout misbehaves. Monthly, cancel with thirty days.
- Shared Slack
- Uptime watch
- 30-day terms
02Selected work
Three builds, and what they actually changed.
Every project below shipped with a number attached to it. We would rather show you a booking flow that earns money than a mood board.
Orchard Lane ProvisionsRetail · Headless commerce2024
A 1,412-SKU catalog that stopped timing out.
Category pages render in 180ms at the edge
Wren & Sons MasonryTrade · Internal tooling2024
An estimating tool that replaced fourteen spreadsheets.
Quotes go out same-day instead of Friday
03How we work
A schedule you can hold us to.
No discovery theatre, no change-order ambushes. You see the real thing on a real URL by the end of week two.
Week 0
Scoping week
Paid, fixed fee, and yours to keep. You leave with a plan, a price, and a schedule even if you walk.
Weeks 1–2
Design in the browser
No 40-slide decks. Real pages on a staging URL you can open on your phone.
Weeks 3–7
Build in the open
Every Friday a deploy preview and a short written note on what moved.
Launch
Hands on the wheel
We train your team, then stay for thirty days at no charge.
04Clients
What they say once the invoices are paid.
Two other shops quoted us nine months. Plumbline had the booking flow taking real money in seven weeks — and they were the ones who told us to cut two features to get there.
“Our old site took 6.8 seconds to show a photograph of a tomato. It now takes under half a second, and the catalog team has stopped filing tickets about it.”
“They spent the first two days in our yard with a clipboard before writing a line of code. The tool matches how we actually estimate a job, down to the waste factor.”
“Three years and four products later we are still on the component library they left us, and the whole thing still looks like one company made it.”
05Start a project
Tell us what you’re building. We’ll tell you what it costs.
Every inquiry gets a written reply within one business day, from the person who would run your build — there is no sales team here. If we are the wrong studio for the job we will say so, and name two who are not.
- Scoping week
- from $4,800
- Full build
- $28k – $90k
- Care retainer
- from $2,100/mo
Fixed price, agreed before we start. The scoping fee comes off the build if you hire us for it.
