Customer.io - Send email based on what people do (or don't do) in your app

We're loyal customers of Customer.io over here at RocksBox :)

Hi folks, I'm Colin, CEO of Customer.io. Happy to answer any questions you have about the product (or anything else).

Hey Ryan, thanks! We actually never did an accelerator. We didn't get in to YC, and the timing never worked out for Techstars. But as a treat for you guys, here's our video from our rejected YC application :) Maybe it's a "what not to do" more than anything :)

Great software! We use it at https://justaskusers.com to send the minimum number of emails necessary at just the right time in our user's workflow!

I'm surprised Customer.io hasn't been shared yet. Great product. We use a similar product, Intercom.io (http://intercom.io), at Product Hunt.

Totally agree, @rrhoover. Was hoping I hadn't missed it looking through the archives.

Welcome, @alphacolin! When we first met, you told me about your early beginning and how you got into YC. It's a cool story. Want to share?

Ahh, my bad. Sorry I was getting mixed up with another conversion. /embarrassing Thanks for sharing the video. I remember filling out the YC application for a project ~3 years ago. Despite the rejection (which honestly, was a good thing), we learned a ton going through the process.

I love customer.io! We use it at on http://dash.ga.co and yo @rrhoover let's start using it here too haha :)

I am in love with and addicted to your product for the 6 months I have been using it. it is extremely powerful. The support is also incredibly helpful. Congrats!

We use Customer.io at Optery and love it. Powerful developer friendly features, but also simple enough for non-technical users to utilize. The user segmentation and event history are very useful. Documentation and support are also great, highly recommended.
