Very interesting. What size team does it take to build this, incl. analysts, project managers, product managers etc.? How long did you spend in analysis before building and the how long to first customer using it?

could I get a link to the Kepler finance site? googling for "Kepler financial" yields 5-6 other finserv companies

Just friction? What do you mean? What would you do instead?

You're misunderstanding something about the problem space they're describing. The deterministic infra is for an underlying "execution layer"; the LLMs are providing utility by figuring out how to express English language queries in terms of the primitives of that verifiable layer. That way, you can describe your results deterministically even though the process of arriving at them was not necessarily deterministic.
