Additional Speaker Details

Using publicly available information we constructed an analysis to help you get a feel for this speaker before deciding to attend their session.

Lotte Seifert is co-founder of SID (YC S23), an AI research lab in San Francisco building agentic retrieval models. She can speak to building a research-lab startup focused on AI search and retrieval — its flagship SID-1 is marketed as ~1.8-1.9x better recall and 24x faster (144 vs 5.7s) than embedding-only/agentic baselines, with a team drawn from Anthropic, DeepMind and OpenAI. Little public stage, podcast, or writing content surfaced, so the speaking signal is low.
