Tessl

Today, we're excited to announce that Tessl has completed our SOC 2 Type II audit.This milestone underscores our commitment to protecting customer data and gives you clear visibility into the security practices behind the platform. As the Security & Compl

At AI Native DevCon London, I talked about agent experience, or AX, because the builder persona has changed. The people our platforms were originally built for are no longer only professional developers. Developers are still builders, but they are not the

I love tests. I have always liked tests, and AI has made me think about testing even more. If AI is going to help us write production code, the important question is not whether it can generate a lot of code quickly. The important question is whether we c

Software factories are the frontier of agentic software development. They promise a compounding development process that gets cheaper, faster, and better every week. But most teams struggle to build factories that deliver these compounding outcomes. Their

Everyone talks about agentic transformation as though the hard part is the agents. It isn't. The agents are getting better on their own, month after month, with no help from you. The genuinely hard part is everything that steers them, the context, the wor

Most of the energy in agentic coding today goes into a single question: how do we make agents do what I want autonomously and effectively? We write a sharper prompt, choose a stronger model, or add a better skill for the task at hand. All of this helps, b

For months, colleagues kept asking me a version of the same question. Could I write down how I approach design, so they could draw on it without waiting on my calendar?The question kept coming back because of how we now build. Tessl runs a software factor

We needed a default model for Tessl Code Review, our new code review tool. The shortlist seemed easy to compare: check the token prices, weigh them against capability, and choose. Then we ran the models on real pull requests through the real review harnes

We're in an intense moment as software engineers. On one hand, coding agents have become genuinely amazing and we're using them all the time with higher and higher throughput. On the other, they build in sloppy, bug-accumulating ways, and we're under unre

When I talked about vibe coding at AI Native DevCon London, I was not trying to dismiss AI coding assistants. I use them. I think they are a major change in the way software will be produced. But I wanted to ask a harder question: if natural language and
