Coding is solved. Software engineering isn't.

AI agents can code a prototype in hours, but coding is only 10% of the work. Turning a prototype into a product that survives the real world needs proper engineering.

Tollens is your agentic companion for the other 90%. We call it deliberate software.

Deliberate software

Software that genuinely serves the people it's built for, while minimising stress for the people who make it.

Engineering deliberate software requires quality-first engineering processes. Decisions are made against a clear understanding of what good and bad look like for the people who matter, and targeted testing discovers the gaps you didn't think of.

Quality-first

Reasoning about quality from the start of the project, starting with why.

Quality is

  • A discipline applied from start to finish
  • Value to people who matter
  • What you're trying to achieve

Quality isn't

  • A phase tacked on at the end of the project
  • Correctness
  • Clean code, no bugs, test coverage*

*These are important proxies for quality, but not quality itself.

Your companion for quality-first agentic engineering

Tollens works with you to define what matters, then leads your agents to engineer it right.

Starts with why.

Tollens talks to your team to surface the assumptions you've never written down, then builds a quality strategy tailored to where your product is now.

Leads your agents.

Your coding agents write code. Tollens feeds them quality context, reviews their plans, and catches when they go off track.

Does the hard part.

Tollens does the hard quality work: reviewing, measuring, testing, finding gaps. That includes knowing when to bring you in: the judgments, the taste questions, the final calls that need a human.

Grows with you.

As your product scales, Tollens keeps asking the right questions, re-prioritising and adjusting as your ambitions grow.
