As you may already know, integrations are the heart and soul for products like this. I'm assuming you're already being bombarded by potential/current users asking "when will you have integration X?".
What is your strategy to scale out & maintain integrations? Speaking from experience, it's not something that is easy to scale out unless you have a dedicated team whose job is to build them out, or you have some third-party provider like CData providing OOTB connectors for your product.
(On a side note, this looks fantastic. Are you hiring any product folks per chance? I have significant experience tackling this same problem).
