01 / The bleed

Type in your SaaS. See what 36 months of rent cost. Then kill it.

We check what your team actually opens, build only that, and hand you the code. Most builds are live within a week. One payment. No subscription. Ever.

02 / The math

The 3-year math your vendor hopes you never do.

Their pricing page shows one month. Your bank statement shows 36. Ten people, cheapest annual prices, in the currency they bill you, checked 24 Sep 2026.

ToolList price3 years, 10 peopleBuild you ownRent ÷ build
HubSpot Marketing Hub Pro$800/mo for 3 seats, $45 per extra seat, $3,000 onboarding$43,140from $8,0005×

monday.com Pro$19 per seat/mo$6,840$2,500–8,0000.9–2.7×

HubSpot assumes 10 editing seats. Salesforce and monday.com charge the same digits in euros: their list price, not our rounding. Sources: vendor pricing pages, 24 Sep 2026.

See the monday row? Alone, at 10 seats, it's a coin flip. Bundled with the CRM it isn't. That's why we ask for the whole list.

03 / How it works

Audit. Build. Own. Most within a week.

Bigger builds take longer. The quote says how long before you pay a cent.

01Day 1

Audit

Send the list. We check what your team actually opens. Half an hour on a call, then a fixed quote within 24 hours. You pay 50% to start.

02Days 2–5

Build

The features you use, nothing else. Preview builds as we go, tested on your real work, not a demo dataset.

03Day 5–7

Own

Deployed on your server, other 50% at handover. Your code under the license you choose, 30 days of refinements included. The subscription gets cancelled. By you. Loudly.

04Every build

In the box

  • The code. Your license: MIT, proprietary, whatever you pick. Hand it to any developer.
  • Your server at no extra cost, or a Hetzner server we set up for $450, once.
  • 30 days of refinements after handover. Included.
  • Maintenance agent, $50/month, optional. The only subscription on this page.

04 / "But what about…"

04 / "But what about…"
01Custom software is expensive.
Compared to what? Starter builds $750–2,500, most replacements $2,500–8,000, a CRM from $8,000. Your CRM alone bills $36,000–43,000 over three years.
02Who maintains it when you're gone?
Anyone. Documented code under the license you choose, not a black box. Or the $50/month agent, or we do, hourly. Not locked to us. That is the point.
03We'll lose features.
You lose the 80% nobody opened. The 20% get built the way your team uses them. More later? Added at cost, no per-seat fee.
04Can't we build it ourselves with AI?
You can. Will you? A week at a fixed price, or six months of evenings and a half-finished repo.
05Where does our data live?
Your server, or a Hetzner server in the EU we set up for $450. No vendor cloud.
06What about the data in the old tool?
It comes with. Export, import script, checked against the original. Priced into the quote.
05 / Send your list

Every tool you pay for: name, price per seat, currency, seats. I reply with call slots. 24 hours after the call: a fixed quote per tool and a kill order.
