Operated SaaS build service

Your idea becomes a real, live product — not a prototype you have to finish yourself.

mimaster turns your idea into a finished SaaS product and operates it for you long term — for founders who have no development team and want neither to code themselves nor to pay an agency retainer. You describe your product in plain language; mimaster delivers the domain, web app, login and payments, hosts and maintains everything, and keeps developing it.

Free and non-binding — mimaster tells you upfront whether your idea can be built. Cancel monthly · revenue share only once live · export anytime.

Each stone a completed task. The keystone locks in when your product goes live.

The problem

You have an idea that could become a product and a business. The trouble is the path there — it is blocked at every door others offer you.

The voices describing this are not invented:

  • «have few ideas that can turn into apps and businesses but can't shell 30-40k to just get something developed.»— teamblind.com, 2026-07-24

    A five-figure agency retainer simply is not an option for a first product.

  • «Developing a prototype is one and keeping something running and improving on feedback is another.»— teamblind.com, 2026-07-24

    Even if you assemble something with an AI builder, the build is only half the work — nobody carries the ongoing operation afterwards.

  • «It will push you into an endless loop of fixing the same rendering issue… In the end, you will lose all your credits for nothing.» (about Lovable)— trustpilot.com/review/lovable.dev, 2026-07-24

    Self-build tools push you into fix loops that burn your credits — and at the end there is still no product ready to run.

  • «I tried hiring ppl in india they did a very bad job at development.. cant trust other[s]»— teamblind.com, 2026-07-24

    And rotating freelancers? Too often a disappointment — with nobody who is accountable at the end.

How it works

Here is how mimaster resolves exactly these three break points — in the order in which they block you.

A

Your idea becomes a finished, live-operated product

You describe your product in plain language: idea, target group, core value, the functions you want. That is your Briefing. mimaster tells you upfront and honestly whether the idea can be built — approval or a reasoned rejection, no flying blind. Then a standalone product takes shape, with its own domain, web app, login and payments, and you follow the build progress transparently in the portal.

B

Nobody stops after launch — mimaster keeps operating

From going live, mimaster carries the full operation: hosting, maintenance, security and new functions keep running for good. When you want to change your product, you phrase a change request in plain language — no ticket system, no handover, no maintaining it yourself. Unlike self-build tools that leave you alone with hosting, backups and data protection once the build is done.

C

No five-figure retainer — monthly, tied to success

Instead of a five-figure cheque at the start, you pay a fixed monthly subscription from CHF 149. On top comes a 15% revenue share — but only once live, and only on the real, measured revenue of your product. So mimaster earns when your product earns. And because you can export code and data at any time, you are never locked in.

Free and non-binding — mimaster tells you upfront whether your idea can be built.

Without invented proof

Before the first customer there are no invented testimonials and no user numbers here. Instead, commitments you can verify.

  • Feasibility statement upfront — mimaster tells you honestly, before the build, whether your idea can be built. No flying blind.
  • Cancel monthly — you are not tied to a year when you pay monthly.
  • Revenue share only once live — the 15% applies only to real, measured revenue. Before live: zero.
  • Export guarantee — code AND data are exportable at any time. No lock-in.
  • Prices in the open — both plans are shown on this page, no «price on request».
  • Visible operator — behind mimaster stands a real, accountable person (Stefan Laggner, previously master.laggner.li), not an anonymous team.
  • Data hosted in the EU/Switzerland — data protection under GDPR/DSG.
Pricing

A live-operated product at a fixed monthly price — operation included.

Prices are per month or per year (a year = 10 monthly instalments, so two months free, around 17% off); both intervals from day one.

Year = 10 monthly instalments — 2 months free (around 17% off)

Plus: 15% revenue share once live — on top of every plan, but only on the real, measured live revenue of your product. It is a share of revenue, not a share of profit and not a share of the company.

Why there is no free trial. A «14-day trial» would prove nothing here — an operated product does not appear in one click. Instead of a trial you get the risk reversal: start free and non-binding, feasibility check upfront, cancel monthly, revenue share only once live, and export anytime. Your risk therefore sits before the first franc.

  • Monthly or yearly? Both from day one. The yearly price equals 10 monthly instalments.
  • Switch between Start and Pro? Anytime, with prorated billing.
  • When does the 15% apply? Only once live, only on real, measured revenue.

Objections & answers

The questions that count before the first franc.

Do I keep control and ownership of my product?

Yes. It is your product and your data. mimaster is the operator, not the owner of your idea. And because code and data are exportable at any time (export guarantee), you are never locked in — you can take your product with you whenever you want.

Why not just build it myself with Lovable or Bolt?

Unlike Lovable or Bolt, where you end up with code you have to host, secure and maintain yourself, mimaster takes on exactly that operation. You do not get a code project to finish — you get a running product at a fixed monthly price, without fix loops and token costs landing on your bill.

How do I cancel, and do I get my data?

The subscription can be cancelled monthly. You can export code and data at any time — independently of any cancellation. There is no lock-in and no deadline holding you in place.

Is this built by an AI — and what happens with endless loops?

mimaster uses modern tools, but the operator is accountable for the result. That is precisely the difference from a self-build tool that sends you into an endless loop and burns your credits: here an accountable person carries the result, not you the debugging.

15% revenue share — is that a lot?

The 15% applies only to real, measured live revenue — before live you pay none of it. It is a share of revenue, not a share of profit and not a share of the company. So mimaster only earns once your product earns, and builds without the five-figure retainer an agency asks for upfront.

I have been let down by freelancers before — why is this different?

Instead of rotating freelancers with no accountability, there is one fixed, accountable operator with a visible name. One party that stands behind the work, with fixed quality and security checks and data hosted in the EU/Switzerland — no anonymous outsourcing.

Can my product even be built?

mimaster tells you upfront. After your Briefing you get an honest feasibility statement — approval or a reasoned rejection. So you invest no money before it is clear that your idea can be built.

You can get the build in many places — the operation almost nowhere.

That is the whole point: building a product is half the work; keeping it live, secured, maintained and evolving is the other half. At mimaster that other half is carried by an accountable operator — not by you on evenings and weekends.

Describe your idea in plain language. mimaster tells you upfront whether it can be built.
