Lighthaven

Lighthaven is a space dedicated to hosting events and programs that help people think better and improve humanity's long-term trajectory.
Since 2023, we've hosted some of the most important gatherings at the intersection of AI, science, and intellectual culture — from David Chalmers exploring AI consciousness at Eleos ConCon, to talented high schoolers learning applied rationality at SPARC, to progress studies pioneers at the Progress Conference.

Our annual festival LessOnline and the prediction markets conference Manifest together bring 600+ writers, forecasters, and builders each summer. We've hosted multi-week programs like the MATS AI safety fellowship and Vitalist Bay's 8 weeks of longevity science, as well as intimate residencies like Inkhaven where 40 writers spent a month publishing daily.
Lighthaven is a project by Lightcone Infrastructure, which is dedicated to facilitating intellectual progress on humanity's most important questions.
