Replace per-seat SaaS with your own system.
We rebuild the simple-but-pricey tools your team actually uses, then host and run them for one flat annual fee. No increasing per-seat bill. Built by senior engineers, at AI speed.
- One flat fee, not per seat
- We build it and run it
- Founders earn revenue share from late joiners
The shift in plain numbers.
There are three ways to get software your team actually uses. Here is what each one costs: upfront, ongoing, and as you grow.
| Rent SaaS | Hire a dev-shop | Your own system | |
|---|---|---|---|
| Cost model | Per-seat, rises every year | €200k–€1M+ upfront; every change a new invoice | One flat annual fee: build, hosting, upkeep & changes included |
| What's yours | Nothing: your data is hostage | The code, but the maintenance too | Your data + a perpetual, escrow-backed licence; your own isolated instance |
| Cost as you grow | Multiplies per seat | Ongoing retainer | Flat: add your whole team for free |
| Who maintains it | The vendor (take it or leave it) | You, forever | We do: senior engineers, on call |
| Build cost | — | Full price, alone | Shared across the founding five → a fraction each |
Everything included, nothing to maintain.
We migrate your data.
Out of the old tool, into yours. No exports, no mess.
We host and run it.
Your own isolated instance: servers, scaling, updates, backups, not your problem. Growing load? We scale your infra.
Unlimited users.
Your whole team's in. Per-company pricing, never per-seat.
Senior engineers, real accountability.
A 40+ person engineering company, founded in 2018, stands behind it — not a prototype that breaks when one freelancer leaves.
Yours to keep.
Your data is fully yours (export anytime) and you hold a perpetual, escrow-backed licence: you keep access even if we ever stop trading. (The platform IP stays with Rollout IT; that is what keeps your price low.)
Expert-built, AI-fast.
Senior engineers set the architecture, review every change, and own testing and release sign-off; AI accelerates the work in between. Need something beyond the core? We build it for you.
The rent trap is real.
Most tools started simple. Then they added features you do not need, raised prices every year, and tied your data to their servers. Here is what that actually costs.
You pay for the whole tool but use only a slice of it.
The bill rises every year, and again with every new hire (per-seat).
Stop paying and you lose access to your own history and data.
You can't shape it: you bend your process to fit their product.
No finish line: you rent forever with nothing to hold at the end.
Replace it once: a system shaped around how you work, on a flat fee, on a perpetual licence, your data always yours.
Share the build. Get paid back.
The more firms join, the cheaper it gets for you, while your data and your private features always stay yours.
Cheaper because it's shared.
~5 firms split one build, so each pays a fraction of a bespoke build.
Founder pricing fixed for 10 years.
No annual hikes. Your cost is locked from day one.
You shape the roadmap.
Priority on the features you need, built around how you actually work.
You get paid back.
5% of each new customer's combined fees (entry fee + first-year licence) is returned to each founding member, until each founder has recovered half their build contribution.
Fair by design.
Later joiners also pay an entry + licence fee, nobody gets your work for free.
Lower risk, expert delivery.
Senior-led agentic engineering; we build it and run it; your own isolated instance.
The more firms join, the cheaper it gets for you, while your data and your private features always stay yours.
Co-found a buildTools worth replacing.
Simple, expensive SaaS where most teams use only a slice of the features. Sort by how replaceable they are and see the rough cost to rebuild.

Can't find your SaaS?
We add new tools all the time. Request one and you'll be first to know.
See what you'd actually save over 5 years.
Assumes ~10%/yr SaaS price increases. Your own system: one-off build split across ~5 founding members (~€9,000 each) + €2,500/yr flat running cost. No per-seat charges, ever.
Co-fund the build. Own the result.
Founders share the upfront cost of a build and the upside that follows. Late joiners come on board after launch with a monthly fee and one-time onboarding.
Gather a few founders
We line up 4 to 5 companies who all overpay for the same SaaS to co-fund one build. Costs split across the cohort.
We build your system
Senior engineers rebuild the workflows your team actually uses — AI-assisted, at roughly a half to a third of a traditional estimate.
Launch & go live
We host and run it for you for a low fixed annual fee. Founders get a say in the first feature set.
Founders earn it back
Late joiners pay to come aboard, and founders receive a revenue share until they've recovered about half of what they put in.
“None of this is an argument that every SaaS product is safe. AI raises the bar, and low-differentiation tools with generic workflows will feel increasing pressure. If a product is essentially ‘a simple database plus a form plus a dashboard,’ customers will ask why they are paying recurring fees for something they can reproduce quickly.”
Forbes
Proof the shift is real — from the industry
Not our project — but proof of the trend: a Kyndryl change manager replaced a commercial ticketing system with an open-source build, removing ~$5M/yr in licence costs (as publicly reported).
Worked example: a typical UK field-service firm with ~30 engineers paying ~€14k/yr for work-management SaaS could run its own system for ~€2.5k/yr — payback in roughly a year once the build share is recovered.
plan to replace more SaaS with custom software, and ~35% have already done so. (Retool, 2026)
"Rollout IT proactively helped us build a new product from scratch: a fast-loading system with a dependable UX."
Grown-up delivery, human support.
Worried about introducing something new to your team? Don't be. You already have the SaaS. We rebuild the same workflows you already know, and stand behind it.
- Rollout IT is a 40+ person engineering company, founded in 2018. Not vibe-coding — senior engineers own delivery.
- Your team keeps the workflows they already know — we match the tool's core flows, with a cleaner UI.
- Senior engineers set the architecture, review every change, and own testing and release sign-off; AI accelerates the work in between.
Questions, answered.
You own your data (export anytime) and hold a perpetual licence to run the system — your contract includes a source-code escrow clause so your access is contractually protected even if Rollout disappears. You don't buy the source code (the platform IP stays with us, which keeps your price low). No per-seat; price fixed for 10 years; your own isolated instance.
Stop renting. Get your own system.
Tell us the SaaS you'd replace. We line up a founding-five cohort, build your system, and run it for you: one flat fee, your data, a perpetual licence.
