SF AI Builders + Engineers Happy Hour by CRV & Comma Capital
We're excited to bring together the best engineers in SF who are building in AI!
Whether your playing around with the most recent open source models, hacking on an AI side project, looking for cofounders or exploring something new, come hang out and discuss the latest in AI and engineering.
Learn about the latest AI technologies as well from our friends at Valyu and Lemma who will be joining us at this event.
About Valyu: Valyu is a multimodal search API for AI. We index web and proprietary sources to power agentic search and deep research. The API returns structured, citable results that LLMs and agents can use directly as context for knowledge-intensive tasks. More and more developers are adopting Valyu as their default search because the results are consistently better than existing tools. As search is becoming a default capability in AI systems and infrastructure, Valyu is built to serve it at scale.
About Lemma: Lemma is the AI experimentation platform for next-gen prompt engineering. In just two steps, we provide teams with the infrastructure to set up structured experiments, measure performance with LLM observability, and automatically optimize prompts and model configurations over a dataset of tests. For teams without curated datasets, Lemma includes an LLM-as-a-judge evaluation framework to enable reliable testing from day one.
About CRV: CRV is a venture capital firm that invests in early-stage tech startups. Since 1970, the firm has invested in more than 600 startups at their most crucial stages, including Airtable, DoorDash and Vercel. Founders need more than capital to build a great company. It takes a partner who understands the entrepreneurial journey and knows what it takes to win. From founding to IPO and beyond, CRV is there every step of the way. Founders rely on CRV to be trusted, long-term, committed partners, which has helped make CRV into one of the longest-running venture capital firms in the world.
