Rudderless Books & Breadworks
Early stageAn online used bookstore paired with a local sourdough bread subscription service. Combining a personal library of 4,000+ books with a baking hobby that people keep asking to buy from.
The Approach
Every venture is built with Ruby on Rails 8, deployed with Kamal, and developed with significant assistance from large language models. We believe LLMs have fundamentally changed what a small team can build and sustain—not because they write the code for you, but because they remove the bottleneck between having the right ideas and shipping them.
The common thread across all of these projects is decades of real-world business experience informing the software design. We build things we would use ourselves, for people like ourselves.
