In my mind, this is the best option for startup bookkeeping right now. It's already pretty good, and bound to only get better as more of it gets automated. To my pleasant surprise, the (human) team was very responsive in answering questions or addressing concerns as things popped up.
Pilot is a no-brainer for startups. The founders are extremely empathetic to the fact that you want to spend as little time as possible managing your books. Their staff is extremely on-top of things, smart, resourceful, responsive, etc.
For example, I asked them to accelerate some work in advance of a board meeting, and one of the founders followed up directly on the thread to make sure it would happen. And BTW, immediately after the board meeting the investors asked what bookkeeping service I use so they could recommend it to the rest of their portfolio.
Keep up the good work!
