Makes sense! For the eventual blog post, I'd be particularly interested in hearing how you decide which small bets to make (e.g. did Corporate Cards start from an employee saying "I want to go work on this"? An internal new-products strategy team? An executive?), and what structures you have in place for deciding when to invest more heavily in a bet.
We are trying to figure out how to do this at Clever, and I know others like Segment (https://segment.com/blog/finding-product-market-fit-again/) are thinking about this as well, so hopefully we can start putting together some advice on how to create an "engine" for layering new products onto an established platform.
