He previously led production Machine Learning teams at Slack and Splunk, and studied at MIT, Stanford, and Berkeley. * Eric Schkufza, PhD - Graft's Co-Founder, joins You.com as a Senior Principal Engineer. He was previously a Principal Scientist at Amazon, where he built the infrastructure that helped train Amazon's first internal proprietary LLM and worked on global-scale machine learning systems. He has a Computer Science PhD from Stanford. They, and the rest of the Graft team, will accelerate You.com's core technology and deepen enterprise adoption. "At You.com, we're constantly looking for the best talent, and with Graft we found world-class technologists who can build scalable infrastructure. We're excited for them to join the team and accelerate our search APIs for AI agents and LLMs," said Richard Socher, Co-Founder and CEO of You.com. "With the Graft team we get world-class engineers who've solved the same business challenges that we're trying to solve. I'm ecstatic to have such strong teammates working on the infrastructure that makes our APIs useful for enterprise customers," added Bryan McCann, Co-Founder and CTO of You.com. "We're extremely proud of what we built at Graft and thrilled to join forces with You.com on this next phase of the journey," said Adam Oliner. "In speaking with Richard and Bryan, it became clear that we see the same opportunity for AI search infrastructure. We all agreed that our work would be more impactful for customers and for the industry if we combined our efforts. This is the beginning of a new chapter for both companies, one that will allow us to offer new, first-of-its-kind capabilities to our customers."
