21solutions is an Austrian IT company helping B2B organizations plan, manage, and build software that moves the business forward.
Three disciplines, one goal: technology that delivers measurable value for your business.
Independent advice on architecture, tooling, and AI adoption — grounded in hands-on engineering experience.
We take ownership of delivery — from roadmap and requirements to stakeholder alignment and go-live, with AI-assisted workflows throughout.
Custom web applications and SaaS products — designed, built, and operated end to end.
We don't just build software for clients — we ship our own. useAccount.AI brings AI-assisted bookkeeping to small businesses: forward an invoice by email and it's booked automatically — saving up to 90% of accounting work.
It's proof of how we work: lean, product-driven, and built on modern cloud infrastructure.
Visit useaccount.ai →Agile by conviction, not by ceremony — small senior team, short feedback loops, no hand-offs.
We align on outcomes and users — not on a 60-page spec.
Working software in the first sprint, not a demo in month three.
Real feedback reshapes the backlog every sprint. Priorities are allowed to change.
Continuous delivery, measurable results, and a product that keeps improving after go-live.
Whether you need a sparring partner for a decision, someone to run your project, or a team to build your product — reach out.
