Helping data teamstrust AI with their datatrust AI with their datatrust AI with their data
//the problem
Producing data work used to be the slow part.
AI agents have changed that, writing transformations, shipping changes, and answering business questions in seconds. They are becoming core operators of the data platform rather than assistants alongside it.
That speed surfaced a harder problem: knowing whether the output can be trusted.
An agent will confidently sum a metric that cannot be summed, or change a join key that silently doubles a number three teams depend on, without knowing the grain is wrong or a dashboard just broke.
And because every system connects to the next, a single wrong answer rarely stays where it started.
Generating answers has become easy, and trusting them has become the work that doesn't scale.
//why we exist
Making this work doesn't take more capable agents. It takes giving the capable ones we already have something to check their work against.
An agent is only as reliable as its understanding of the system it operates on: every model, metric, dependency, and definition, and how they connect.
Most agents have almost none of that context, which is why their output can look right and still be wrong.
Typedef provides that foundation: a live context layer, compiled from your code, that checks every answer and every change against how your data actually works.
It lets teams hand more of the platform to AI without giving up correctness.
That's what we're here to enable.

We're building the next generation of tools for modern data teams. We need people who think that's as exciting as we do.
At Typedef, we're a crew of engineers and builders from places like Google, Snowflake, Salesforce, and Netflix. We argue about the best pastry at Backhaus and the top noodle spot in San Mateo just as intensely as we argue about context retrieval strategies and agent evaluation benchmarks.
If you care deeply about data infrastructure, developer tools, and making AI-assisted engineering actually work in production, we should talk.
