Pros
It was great to walk into a start-up environment (this was 2013) with very mature, strategic relationships with senior management at many of the top global companies in financial services and other industries. It was exciting to have access and interaction with the founders, witness and contribute to the roll-out of Relcapp's SaaS analytics solution and consulting engagements. It was useful to see how feedback from their key initial clients shaped the evolution of their service through constant iteration. Appreciated working in a collaborative environment with smart, hard working people across the board.
Cons
The challenges were what you would expect at company that early in it's life, but I knew that going in. There was plenty of hard work, late nights and stress around successful delivery to key anchor clients, and big bets on the service strategy. I've been gone for about 1.5 years but Relcapp seems to have won some big new SaaS clients and I got some good informal feedback from a couple of existing clients.
