Exceptional Software. Beautifully Made.
Calculated by name. Calculated by nature. We exist because we understood something most dev agencies don't: good software isn't a tech project — it's a business project. The question was never "What can we build?" but "What's worth building, and why?" That economic lens is kalkyl's core. We calculate the ROI for our clients before we write a single line of code. Since 2018, our now 13-person team in Nürnberg has built custom web and software solutions for over 100 clients — from Siemens, ver.di and the Metropolregion Nürnberg to "Mittelstand" companies, startups and public sector organisations. Our work typically includes: Client portals & self-service platforms Custom SaaS products AI integrations & internal AI tools Complex web applications Exceptional UX design What makes us different: Honestly? We're weird. Our developers spot an inconsistent border-radius before they notice you've entered the room. Our strategists will question your business case before they ask your name. That obsessive precision is the product. It's why our software ships clean, scales well, and doesn't need duct tape six months later. What it's like working with us: Full owner access to GitHub from day one Full access to Figma -> review, comment on, and follow every design decision live Daily deployments to a staging environment you can test yourself Daily async progress updates in your Slack or Teams A designated project manager Linear access with transparent time tracking 4-eyes code review on every pull request Documentation and handover that lets you switch teams tomorrow if you want to. You won't want to, but you could ;) Sounds like the partner you've been looking for? Let's do the math.

  • Description
    We build client portals, SaaS products and self-service platforms in C# and SvelteKit. Near bug-free. Designed so users actually come back. We prioritise UX higher than most clients expect: because good design is what makes users return, not just show up once. What you get: Software that ships clean and looks like a product, not a project. Daily async updates directly in your Slack or Teams. No disappearing for two weeks: you see progress every day and can course-correct in real time. 100+ clients since 2018, from Siemens and ver.di to startups and SME's.

  • Description
    Great software starts with great UX. We design clear, scalable interfaces for SaaS products, client portals and internal tools using Figma and component-based design systems. Instead of static mockups, we create structured design systems ready for development. What you get: Daily design updates directly in Slack or Teams, reusable components instead of isolated screens, and UX that developers can actually implement.

  • Description
    You search for AI that creates actual value? We built ka1.ai, our own AI platform. We know the stack: LLM integration, MCP, document intelligence, internal copilots, automation systems. Our approach: AI is an extension of deterministic code. We deploy it where it creates measurable value — not where it sounds impressive. No low-code n8n chains. We build managed, production-grade AI automation that we design, deploy, and maintain. What you get: AI that works inside your real workflows, daily progress visibility via Slack/Teams, and a team that tells you when AI is not the answer.

  • Description
    You don't have a software problem. You have a process problem that nobody turned into software yet. Half our clients come to us with a vague feeling that "something needs to be digitalised." The other half have legacy software their team avoids. Both get the same treatment: we understand the process first, calculate whether building makes financial sense, and then ship something clean & shiny. No bloated ERP. No SAP junior consultant. Just software shaped around how your people actually work.

Collaboration

What was the objective behind your collaboration?Unser Ziel war es, eine moderne und einfach zu bedienende KI-Plattform zu entwickeln, die verschiedene führende KI-Modelle an einem Ort bündelt. Gleichzeitig sollte sie für Unternehmen eine kosteneffiziente Lösung bieten, bei der nur eine Company-Lizenz mit unbegrenzten Nutzern benötigt wird und lediglich der tatsächliche Verbrauch bezahlt wird. Außerdem war uns ein hochwertiges, intuitives Design wichtig, damit die Plattform im Arbeitsalltag schnell und unkompliziert genutzt werden kann.

What did you enjoy the most during your collaboration?Besonders gefallen hat uns die sehr professionelle und zuverlässige Zusammenarbeit. Das Team hat unsere Anforderungen schnell verstanden und in eine moderne, gut strukturierte Plattform umgesetzt. Kommunikation und Projektmanagement waren transparent, und alle vereinbarten Meilensteine wurden pünktlich geliefert. Auch das Design und die Benutzerfreundlichkeit der Plattform sind wirklich gelungen.

Are there any areas for improvements?Insgesamt sind wir sehr zufrieden mit dem Ergebnis und der Zusammenarbeit. Kleinere Optimierungen ergeben sich natürlich immer während der Nutzung einer neuen Plattform, aber das Team reagiert schnell auf Feedback und entwickelt die Lösung kontinuierlich weiter.
