From real work

A little less chasing.
A lot more doing.

A follow-up waiting for an owner. A call worth learning from. An order ready to move. Here are three ways we bring the next step closer.

Book a time to talk it through

Hi, I’m David.

Pixel portrait of David.Founder & builder, AC0
Product. Sales. Operations.

I work across product, sales and operations, and build the connections between them. You work directly with me, from the first conversation to everyday use.

I also edit the Data Licensing Index, an independent, sourced index of who pays companies to license their internal data to AI labs.

Why the name AC0?

AC⁰ is a class of problems solved by polynomial-size Boolean circuits with constant depth. AND and OR gates can take any number of inputs; NOT gates are also allowed.

The inspiration: bring more context together without adding layers of handovers. The same three steps, from problem to working flow.

The computer science behind the name ↗
Is this a good fit?

You have recurring work, existing tools and someone who owns the outcome. We agree on a specific workflow, the required access and the fee before starting.

Finding product-market fit or rebuilding an entire business falls outside this engagement. Additional workflows are scoped separately.
