David Colby

Product & Engineering Leader

I am currently a Director of Product Engineering at ClickFunnels. I build teams of engaged, productive, and effective product builders. I especially enjoy revitalizing teams that have previously struggled to deliver value to customers.


I write about Ruby on Rails, Turbo, and Stimulus often and have published a book on modern Rails development with Hotwire.


I help bootstrapped founders build the product they need and design product and engineering teams that scale.

Breaking out of the loop

The pandemic accelerated a trend towards isolated lives and trapped many of us in a phone-centered time loop. I help people find ways out of the loop and back into in-person engagement.
