Software that took a team months now takes weeks — if you know how to hold the new technology. monstrous.dev builds software with LLMs: smart, quick, reliable — together with you, priced on results, never on hours.
“The technology that could give a small company an edge was locked behind big-company budgets and jargon. That lock is broken.”
Why monstrous.dev exists
Software that gives a small company an edge — orders that run themselves, reports that write their own first draft, customers who book and pay without phoning you — used to cost big-company money and take big-company time. No more. LLMs, the engines behind the AI you’ve heard about, let a focused builder make in weeks what took a team months.
monstrous.dev exists to hand you that edge. We build together with you — in your language, not ours — and we price on the result, not on our hours. If software isn’t the answer, we’ll tell you that too.
A session, not a sales call. We sit with you, map where technology creates competitive advantage and where more value is hiding, and you leave with a plain-English plan — including the exact price of building each part of it.
€100–500.
That’s the whole cost of finding out what your edge is worth. Less than most people spend on software they don’t need.
After Ideation, we build a small working version so you can touch the thing before the big price. Reacting to something real beats approving a document.
We build solo, then show you what works. Every demo is a steer point: keep going, change course, or run what exists now. Your call, every time.
Never hourly. After Ideation you get good calculations upfront, and every build is priced against your goal and measurable results — so if it works, it was worth it; if we said it would, it does.
Greenfield: a blank page and an LLM engine. Software that reads, writes, decides and checks its own work — the kind of build where the new speed really shows. Your advantage is the point; the technology stays our problem.
See the full pathWe run what we build — improving and refining it as your company uses it. Our own apps have run in public for years; yours gets the same treatment.
We don’t just build for clients — we build and run our own products on the same craft. Each .monster domain is a product idea taken all the way to a live app.
