Does your data spark joy?!

I build things
that ship.

I’m David Wrench, Co-Founder of datajoi — a team of data agents that ingest, model, and validate around the clock so you can stop babysitting pipelines. A decade of data science and zero-to-one product work, with a veteran’s discipline. Bring an idea, a dataset, or a half-built product and let’s get it shipped.

I love to build.

From wire-guided missiles to data science to founding datajoi — I’ve spent my career turning hard problems into working systems. If you have an idea, a dataset, or a product that needs to exist, reach out.
