Aivelin — AI Systems

AI Systems
That Do
Real Work.

We build apps, websites, automations, and custom AI systems for teams that want practical outcomes — not polished demos and vague promises.

Built for practical, high-leverage work ↓

“Aivelin rebuilt our client portal with an AI chatbot in two weeks. Clean code, zero shortcuts.”

Marcus T.SaaS Founder

“They don't just prompt AI — they architect systems. The difference is night and day.”

Sarah K.Agency Director

“Our automation pipeline saves 20 hours a week. Best investment we've made this year.”

Jonas M.E-commerce CTO

“The chatbot handles 60% of our support tickets automatically. Our team finally has breathing room.”

Lena B.Head of Customer Success

“Every other agency vibe-coded something fragile. Aivelin shipped something I can actually maintain.”

David R.Startup CTO

“Finished in a fraction of the time I expected. No hand-holding required — they just knew what to do.”

Priya M.Product Manager

“We had a rough spec and a tight deadline. They turned it into a production system that's still running flawlessly.”

Tom H.Tech Lead

“The UI they designed converts better than anything we'd had before. Revenue is up 30% in two months.”

Clara V.E-commerce Owner

“Finally an AI team that cares about security. Everything was validated, audited, and documented.”

Stefan W.Information Security Lead

“They integrated three separate APIs into one seamless workflow. What looked impossible took ten days.”

Nico F.Operations Director

“Most devs write code that works today and breaks tomorrow. Aivelin builds systems that hold up.”

Hanna J.Engineering Manager

“Our AI pipeline now processes 5,000 records a night without anyone touching it. Game changer.”

Ravi K.Data Engineer

“The chatbot they built understands our product better than some of our junior support staff.”

Amelie D.SaaS Co-Founder

“Transparent process, clean handover, and zero drama. Exactly what a build partner should be.”

Felix O.Project Director

“They spotted two major architecture problems before we even started building. Saved us months.”

Yuki T.Backend Engineer

“Our CRM automation alone has recovered over €12k in missed follow-ups since launch.”

Monika S.Sales Operations

“I've worked with five AI agencies. Aivelin is the only one that thinks before they code.”

André L.Digital Strategist

“Onboarding flow went from a 3-email chain to a single smart form with AI validation. Users love it.”

Julia P.UX Lead

“Responsive, professional, and honest when something would take longer. Exactly what I needed.”

Ben A.Freelance Consultant

“The monitoring dashboard they built shows me exactly what my AI workflows are doing at any moment.”

Kaspar E.DevOps Engineer

“We scaled from 100 to 10,000 users without touching the backend. That's real architecture.”

Natasha R.Startup Founder

“Reflekt is exactly what journaling apps should have been from the start. Can't wait for it to launch.”

Max B.Beta Tester

“They don't just deliver — they explain. My team learned more in the handover than in any training.”

Irina V.Internal Tools Lead

“The design is clean, fast, and feels premium. Our bounce rate dropped 40% after the redesign.”

Chris M.Marketing Director

“I was sceptical about AI automation, but the ROI was obvious within the first week.”

Laura N.Agency Owner
