QLab Demo Day 2026

​📍 Klarman Hall HBS — Boston, MA
🗓️ Tuesday, September 29, 2026
🕓 4:00 PM doors | 4:30 – 7:30 PM program
🎤 Surprise keynote speaker
🍻 Happy hour to follow

​Industry, government, and the investor community in one room with the QLab 2026 cohort — an afternoon of pitches and demos from the stage, opening with a surprise keynote and closing with a happy hour.

​This is the capstone of the QLab year, and a showcase of what Cambridge does best: research moving out of the lab and into something real. The founders spend the year building. This is the afternoon they present it to the people who can pull it forward.

​Who's in the room

​🚀 QLab founders — the full 2026 cohort, presenting the work they've spent the year on.

​🏭 Industry — operators and technical leaders from the companies these teams are building toward.

​🏛️ Government — program and procurement leads from federal and state agencies working on the problems this cohort is closest to.

​💰 Investors — early-stage funds and angels active in deep tech and Cambridge's research-driven company formation.

​🌐 The QLab network — alumni founders, lab partners, and mentors from across the ecosystem.

​The afternoon

​4:00 — Doors open
4:30 — Surprise keynote
4:45 — Pitches and demos begin
7:30 — Happy hour

​The presentations give you the shape of what each team built. The happy hour is where the intros, pilots, and next conversations happen. Come for both.
