Amazing idea. Building a truly robust and reliable webhooks ‘service’ is harder than it seems. We just finished rebuilding ours and I looked for a service like this before starting but couldn’t find any. Sure, maybe some tech companies will prefer to do an in-house thing, but I can definitely see the value.

Our POV from when we built ours, if it helps: delivery must be reliable, we need visibility on every delivery attempt (status code, response body and headers), some control in retry logic, must be able to add headers (in our case we add a signature), must be replayable if needed, every attempt must have a unique ID, and must be able to send callbacks as a webhook back to our API. Good luck and congrats for being accepted at YC.
