Hey HN! I’m Chris – one of the co-founders at Knock (https://knock.app). Knock is notifications infrastructure for developers. We provide a set of flexible API primitives you can use to power complex notification systems, without having to roll your own notifications infrastructure in-house. In short: we built notifications so you don’t have to. We learned about scaling notifications systems the hard way. Previously, my co-founder and I worked together at Frame.io, where we saw the upside of product notifications as well as the pain involved in building and maintaining them. With…
