Engineering studio · one project at a time

We buildthe stone —what a businessgrows from.

Cherrystone designs and builds complex web systems: platforms, client portals, operations consoles. Not landing pages, not “one more website” — the core a product stands on for years.

01 — position

We are not looking for any work. We look for problems where the right system changes the economics of a business: removes manual labour, opens a revenue channel, turns a service into a product. There are few such projects — and only those are worth doing properly.

02 — filter

What to bring us, and what not to.

Yes, that’s us

  • A platform the whole business runs on3+ months
  • A subscription product with portals and billingSaaS
  • An operations console replacing ten spreadsheetsoperations
  • A system others couldn’t finishrescue

No — and that’s fine

  • A landing page by Friday
  • “Like the competitor’s, but cheaper”
  • Developers rented by the hour
  • A project with no decision-maker
03 — proof

Numbers from git, not from a pitch deck.

0days

From first commit to a platform in production.

0releases

Not “we’ll ship at quarter end”. 63 releases on the peak day.

0screens

Back office: bookings, inventory, finance, analytics, chat, billing, roles.

0checks

Automated checks run on every deploy — which is why 63 releases a day is safe.

04 — method

First the stone. Then everything else.

In every serious system 60% is the same: roles and access, analytics, media, notifications, chat, backups, data retention. We wrote it once, as a core, and hardened it until it can be lifted out and dropped in.

So your budget goes not into “auth and an admin panel”, but into what makes your business different.

Two systems. Both live in production.

01 · SaaS · 2026

DetailClub — a subscription platform for detailing studios

Each studio gets its own site, online booking, inventory, payroll and analytics. Above them — headquarters: plans, billing, demo instances, field sales.

EatFit — a nutrition and training diary

Same foundation, a completely different product. The core moved as is; the new domain was written beside it and never touched it.

Four questions. An honest answer on whether we fit.
