Claude Code, Cowork and the changing shape of business

Claude code and cowork are fascinating. The whole business structures can change.

I wanted to build a testing tool for 6 different models of VaR calculation. Then to verify them, to produce a way to benchmark keeping thousands of live portfolios in memory. Including one using tensor decomposition to approach the space for the other side.

Non trivial stuff. The sort of POC I would have worried about commissioning. It happened on the side whilst I was attending to other tasks. It scraped asset data to run tests, built a decent enough set of portfolios. All so I could see what the incremental processing cost is.

These are game changers.

My other box was running excel with the Claude plugin. It needed a lot of guidance but the pace to build adapt and change financial models is unworldly. I’ve spent years stripping swap curves testing calendar data and building models for swap curves, inflation swaps and swaptions. You need to know the maths to verify it, you need discipline to put testing in, but the pace of development of models is incredible.

I don’t think business have the same shape in the future. Much flatter. High comms between smaller groups with adaptable tooling to solve issues fast to prototype and test. All the structure have to change to embrace, support and protect businesses as this tooling reaches us.

Even now I’m over 50 I’ll always be an early adopter testing new technology. Incredible times.
