The notebook of Jedidiah Francis

What can a small team build now?

I’m Jedidiah. I’ve kept notebooks for years, usually with more questions than answers. I’m opening a few of them here. Come and explore what’s on my mind, and if a question catches your imagination, I’d love to hear where it takes you.

Field note 01

A seven-figure ambition.
The first 21 days.

Visit EasyCalculator
Hypothesis
Could one founder use AI to build a seven-figure business? The first test was narrower. Could I launch a useful product in three weeks?
Experiment & result
I chose calculators because their answers could be checked. By day 21, eleven were live. That established how quickly I could ship. Demand, retention and revenue were still open questions.
Commercial implication
I could build that first version faster today, and so could a competitor. The next test is whether I can reach customers at a sustainable cost, give them a reason to choose us, and earn a second visit.
Background

Living things, learning machines,
and a workbench.

I’m a London-based founder and data scientist. Biology took me to Oxford to study evolution and later to ASOS, where I built the data science team. At The Shipyard and Hairouna Labs, I’m pursuing two questions that grew out of that work. What can a small team build, and how do individuals learn to act together?
