Impact

Three levers, and we pull them for you.

Each one shows up in reporting, not in a satisfaction survey. Which of them pays back fastest in your portfolio is settled after the audit - before a line of code is written.

How we work

We automate manual processes - headcount cost falls for good.

We shorten cycle times and release capacity that is tied up today.

We lift EBITDA margin without buying revenue to do it.

Our approach

Off-the-shelf software was the right compromise.

Available immediately, maintained, cheaper than building your own - for years the best balance of price and capability. The reason was always the price of bespoke software, never its value.

AI-assisted development has collapsed that price. The advantage of a system built exactly around your process has not changed at all. Closing that gap is the work - in five steps.

Case studies

Our solutions across the value chain.

From a publishing group to pharmaceutical research to a listed software group - three systems in daily use, with results that show up in the client's own reporting.

Heinen Verlag

More than 1,500 complaints a month, captured automatically - by phone and over WhatsApp.

For Rheinische Direktwerbung, a subsidiary of Heinen Verlag, we built an omnichannel intake for customer complaints. An AI agent takes the case, captures the required details and hands them straight to the target system - with nobody taking notes or retyping afterwards.

Roche

An internal platform where research teams run experiments, workflows and data in one place.

A central environment for planning laboratory experiments, steering lab activity and managing the data around it - in effect an operational layer around the research work itself.

Visma

A phone assistant that answers questions about the software - instead of only routing them.

For H&H Berlin, a Visma Group company, we built a phone assistant for customer support. Through a RAG connection it reads the complete product documentation and answers questions about the software rather than passing them along.

About SF Software Labs

An AI-first software studio - one that builds for itself first.

Part of our work goes into products of our own: we build them, run them and take them to market ourselves. The other part is client work - software for portfolio companies, cut to their processes and their numbers.

That dual role is the core of the offer, and it is deliberate. Anyone who only ever builds to order never learns what software costs to run, where it breaks under load, or what the market will actually pay for it. We learn it every month on our own products - and carry the consequences ourselves.

Our team consists of former FAANG engineers and VC-backed startup operators. Our previous company, AI Union, served as the forward deployed engineering team for fonio.ai and Superchat - connecting complex systems to AI for more than 300 clients since 2023.

Our own products
