For very small funds, running entirely on IBKR platform (or Alpaca if you can live with their constraints) makes sense. For very large funds, you invariably will have a home-grown system that integrates with all of your expensive vendors. But if you are starting from scratch and want to scale up, using this to bootstrap quickly is most efficient.
