Arvind Sujeeth is the co-founder and CEO of Billables AI, a San Francisco startup that automatically captures and writes lawyers' billable time entries from the tools they already use. A Stanford PhD in computer systems, he helped create OptiML and the Delite framework for parallel machine learning, then spent years building generative-AI hardware and software as VP of Engineering at SambaNova Systems. His first company, mines.io, used machine learning to underwrite microloans in emerging markets. The idea for Billables came from his wife's relentless monthly griping about reconciling her timesheets - a problem he reframed as one of the most painful, money-leaking chores in professional services. In 2024 the company raised $3.9M in seed funding led by Wing VC.
Rodrigo Liang is the co-founder and CEO of SambaNova Systems, an AI infrastructure company he built from the ground up in 2017 alongside Stanford professors Kunle Olukotun and Chris Ré. Born in Taipei, raised in Brazil, and trained in electrical engineering at Stanford, Liang spent two decades designing high-performance processors at Hewlett-Packard, Sun Microsystems, and Oracle before betting that the entire computing paradigm for AI needed to be reimagined. SambaNova's Reconfigurable Dataflow Unit (RDU) is the architectural expression of that conviction - chips designed around data movement rather than instructions - and in February 2026 the company announced the SN50, claiming it runs agentic AI 5x faster than competing chips at 3x lower cost, backed by $350M in Series E funding and a strategic partnership with Intel.
