We build your product. Then we stay.
Live in four weeks. After launch we keep it online, secure, fixed and getting better every week — for a flat monthly fee. You never have to hire a dev team, and nobody disappears after go-live.
Some of the products we have built.
Marketplaces, job boards, fundraising platforms, data feeds, AI tools, a Chrome extension. All live — open any of them.
Emptera
One curated European acquisition, every morning — not 500 listings. AI-scored, delivered with a deal playbook.
Übernahme-Radar
DACH-only entry tier of the same platform. One curated distressed deal per morning, from €39/mo.
changemaker
Every live vacancy at the UN system, development banks, EU, and INGOs — one independent index.
Finseats
The independent index for finance careers. Every live vacancy across banks, funds, fintech and markets.
UniChapter
English-taught master's in Germany you can still start. Live-intake board, AI advisor, relocation course.
Sport Fund
Athlete-first fundraising. Family, clubs and sponsors back equipment, travel and competition.
Talentists
AI tutor for K-12 that keeps the screen off. Paper worksheets do the work; scan when stuck.
MyStudyFund
Free fundraising pages for students. One-time or monthly. Stripe-verified payouts, 60-second setup.
Flash Interview
2-minute unscripted video intros. Hiring teams evaluate personality — not polished resumes.

OpenTraid
Real-time commerce infrastructure for AI agents. Automated trading in AI-driven marketplaces.
ProductLeader
Turns PM resumes into case-study portfolios. Metrics, impact stories, strategic framing.
DevotionFund
Christian fundraising for missionaries and volunteers. Dignified giving for faith-based missions.
ChiefOS

products
Full portfolio with case-study depth on each build.
Most studios leave at launch. That is when the work starts.
A product needs someone after it goes live. The usual options don't stay.
A normal day on a product we run.
Nothing here needs a ticket from you. You get a short report every month: what ran, what broke, what shipped, what's next.
Prices.
Pay once to build. Pay monthly to keep it running. Pause or cancel any month; everything stays yours. Excl. VAT.
Hosting, domain, email and payment fees run on your own accounts — typically €20–80 a month at launch. Equity in place of fees is possible for a small number of ideas a year; ask on the call.
Who we work with.
Founders with an idea and a market.
You know who needs it and how they'll pay. You want it to exist — and keep existing — without becoming a software company.
Owners of a product nobody maintains.
The developer moved on, the agency contract ended, or the no-code build hit its ceiling. The users are still there. Someone needs to take the keys.
Consultants and agencies who need a build partner.
You own the client and sell the outcome. We build and run the software behind it, at a price you can quote.
A team of senior product builders.
Product leads and engineers who have spent careers shipping software — running product teams, co-founding companies, and building and operating products across hiring, finance, education, fundraising and M&A.
We work with our own operations tooling that watches every product we run: probes, security scans, error triage, verified deploys, reporting. That is what lets a small senior team keep many products healthy — and it is what you get with Run.
No account managers, no juniors, no hand-offs. You talk to the people who build it and keep it running.

Questions.
Do I own the code?
All of it. Hosting, domain, payments and database run on accounts in your name. If you leave, everything keeps working and you take it with you.
Can I cancel the monthly plan?
Any month. You can also pause. No exit fee.
Can you take over a product someone else built?
Yes. Run and Grow start with a takeover: we read the codebase, fix what's broken, set up monitoring and deploys, then operate it. Usually within two weeks.
Why is it cheaper than an agency?
Senior builders only, plus tooling that does the repetitive operations work. No account managers, no juniors, no hand-offs.
What can you build?
Web apps and SaaS: marketplaces, job boards, fundraising platforms, data products, internal tools, AI workflows, browser extensions. Not native mobile apps.
What happens in the four weeks?
Week one: scope and design, with a live URL by Friday. Weeks two and three: build, demo every Friday. Week four: polish, payments, analytics, launch.
Tell us what should exist.
Thirty minutes. You leave with a fixed price and a start date — or a straight answer that we're not the right fit.
