Theo Patt
Co-founder & CTO
With Knock we had an in-app feed up and running in minutes. Knock gave us the
time back to focus on our core product and the peace of mind to know our
notifications were built on a foundation that we can scale with moving forward.
Chris Shilling
Co-founder
Knock allowed us to spend more time on the features that differentiate our
product, while still providing a world-class notifications experience to our
users.
For an early-stage team—where speed and focus are all that matters — Knock was a
no brainer.
Ali Rizvi
Software engineer
We came across Knock when we were looking to batch email notifications. With
Knock, we were up and running in no time. The product is intuitive, the docs are
great, and the team at Knock went above and beyond to make us successful. We
were also able to easily do in-app notifications using Knock and build workflows
that allow us to notify our customers over multiple channels.
I highly recommend Knock to anyone looking to build product notifications.
Anmol Maini
Full-stack engineer
We were looking to add in-app notifications to Standard Metrics when we came
across Knock. Their well-documented APIs and composable React components made it
super simple for us to get notifications up and running in minutes. Knock saved
us countless hours and headaches from trying to build and scale this internally
and let us focus on building our core product.
Angel Herrera
Co-founder & CEO
Before Knock, we had "notifications" that consumed our time and barely worked.
With Knock, we got easy-to-manage notifications that always deliver, with
support for batching and intelligent routing.
Knock has saved us countless hours and allowed our engineering team to focus on
our core business. A true superpower.
Rik Lomas
Founder & CEO
Adding notifications to products is hard. Knock has been invaluable for our
product development and has saved us a ton of time. Knock's focus on great
developer experience means that it has been incredibly easy to integrate
best-in-class notification systems into new and existing products of ours.
Guillermo Rauch
Founder & CEO
Notification infrastructure is the most essential part of any product that I'd
never dare build myself from scratch or operate at scale. Knock's APIs allow me
to focus on my frontend experience, while all the complexity is abstracted away.
