Recent work: a Hungarian pop-culture heritage AI search engine (presented at AI Summit Budapest 2025), a B2B construction-materials Q&A database from 100+ GB of supplier PDFs, and several production customer-support chatbots.
How we work: discovery -> Figma designs -> 2-week sprints with a working demo every Friday -> automated and manual QA -> release with monitoring -> optional monthly retainer.

- Every engineer is in-house, in CET. No subcontracting, no overnight handoffs.

Our Story
AppForge is a small, senior engineering team in Budapest. We started in 2024 to build software properly - in-house, with engineers who know the stack and the local market - for SMB and midmarket clients in Hungary and across the EU. We work on web, mobile, e-commerce and AI projects, and we lean prototype-first: clients usually have something clickable to react to within the first sprint. Most stick around afterwards on a monthly retainer.
What Sets Us Apart
Speed and flexibility
Clients consistently tell us we move faster than larger agencies, with less back-and-forth. Scope changes mid-sprint, weekend pushes, last-minute investor demos - we adapt without renegotiating the SOW.Prototype-first, not slides-first
We earn trust by showing working software early. Most projects have a clickable prototype within the first sprint - so clients can react to something real before we go deep on production code.AI is built in, not bolted on
We've been shipping production AI - RAG chatbots, document pipelines, on-prem LLM infrastructure - since day one. AI capabilities slot into web, mobile and e-commerce projects naturally, not as a separate line item or 'AI consultant' bolt-on.Locations (1)
