Washboard was a subscription service that mailed quarters to people who relied on coin-operated laundry but hated making trips to the bank for change. The product was built around a tiny but real inconvenience: apartment laundry rooms often had no change machine, banks kept inconvenient hours, and card-enabled laundry machines were still far from universal. By packaging that problem into a simple monthly service, Washboard turned an everyday annoyance into a memorable convenience product that quickly attracted national attention.

Technically, Washboard was lean by design. We built it with PHP, MySQL, and Stripe, with the real challenge being less about complex engineering and more about turning an unusual but legitimate pain point into a working product people could immediately understand and buy into. The most interesting part of the build was product execution: shaping a clear value proposition, creating a straightforward purchase flow, and learning very quickly how payment, shipping, and margin constraints can define the limits of a business.

Washboard was featured in Gawker, NPR, GQ, Time, Inc., Laughing Squid, Business Insider, Vox, Pando Daily, CNET, Daring Fireball, Engadget, and even a question on Who Wants to Be a Millionaire.
