Bucket Robotics is making defect detection faster, easier, and more deployable — starting with the 250M lbs of plastic wasted annually in U.S. manufacturing. Our platform turns CAD files into defect detectors. We generate synthetic, photorealistic training data to help factories catch flaws before they ship. No manual labeling, no real defects required. Our models deploy to edge hardware and integrate easily into existing automation stacks. We come from the self-driving world (Argo AI, Uber ATG, Stack AV), where we built reliable perception in high-noise, real-world environments. We're applying that experience to manufacturing: robust sensing, user-friendly interfaces, and fast iteration cycles. Manufacturers hesitate to adopt new sensing due to data concerns, integration risk, and poor UX. We’ve handled petabytes of regulated autonomy data — and built systems that earn trust. Legacy vendors like Keyence and FLIR offer hardware-centric tools with bloated pricing and outdated software. We’re building the opposite: flexible, modern tools that engineers want to use. Manufacturing is in the middle of a $700B automation wave across North America. Bucket Robotics is building the quality control infrastructure to match.

Bump was acquired by Google in 2013. The Bump and Flock apps were shut down, but our unreleased Photoroll app went on to become the basis for Google Photos, which we led from inception to more than 1B users. Bump let you exchange contact info and photos by bumping phones together. Bump was one of the all-time top mobile apps, amassing more than 150M installs by 2013. Flock was a semi-automated photo sharing app that figured out which photos you took with which friends and created private shared albums. Bump was co-founded in 2009 and received funding from Y Combinator, Sequoia, and Andreessen-Horowitz. We were based in Mountain View, CA.

Bunkerhill is a Sequoia/Felicis/YC-backed company whose goal is to increase the adoption of AI in healthcare, in order to help doctors catch deadly diseases earlier. Bunkerhill Health has built a consortium of research institutions (Stanford, Johns Hopkins, Harvard, etc.), who develop and validate AI algorithms seamlessly under our legal umbrella (less than one week of setup time for a new project when using the Bunkerhill consortium, versus a year or more for projects outside the consortium). Bunkerhill then manages the FDA clearance and commercial sales process for the algorithms that these institutions develop and validate with us. We’ve signed commercial contracts and deployed algorithms with the world’s leading health systems—UCSF, Mayo Clinic, Georgetown/MedStar, and several others. These algorithms help doctors identify patients earlier than has otherwise been possible, leading to better treatment outcomes (early clinical screening for heart disease, pancreatic cancer, etc.) We’re backed by world class investors: Sequoia, Felicis, SVAngel, Optum Ventures, Max Levchin (co-founder of PayPal and Affirm), YC, DCVC, and Pacific8.

Bunkyr enables companies to protect their users’ data with a simple, hardware-secured API. When a user forgets their password, applications using Bunkyr can provide them a familiar, robust recovery method to restore access to encrypted data. Zero-Knowledge architectures and end-to-end encryption are the only true safeguards against data breaches, but come with large user-experience burdens and engineering overhead. Bunkyr eliminates these obstacles in a way that is friendly to both developers and users, cost-effective, and extremely fast. Users won’t even know Bunkyr exists, while their data stays protected against both breaches and lost passwords.
