Purpose-built by thoughtbot

What it does

Building great products is hard. Purpose-built is a new tool from thoughtbot to bring expert advice to founders (and founders-to-be), no matter their level of technical expertise. It features interviews and case studies with amazing entrepreneurs and insights from great business minds. But we're just getting started, let us know what you need!

The latest design, development, and technical leadership resources from thoughtbot.

Work alongside the thoughtbot team as we collaborate with each other and our clients, live. Ask us anything, we're live right now! We continuously learn new things, and share those things with you. Whether you're just getting started with Ruby on Rails, leveling up your product team, or founding your next company - we've got you covered. Looking for Upcase? Upcase was our popular educational platform for learning Ruby and Rails and other technologies. It has been retired, but our team is still sharing learning resources for Rails, AI, and other technologies every day. For team leads who care about quality code and continuous improvement, we've pulled together some of thoughtbot's most…from thoughtbot.com
