On Your Mark Returns for JPM Week 2027, with a Live Site Alongside the Guide
August 18, 2026
Big4Bio is bringing back On Your Mark, its guide to the events surrounding the J.P. Morgan Healthcare Conference, for JPM Week 2027 in San Francisco.
First published in 2017, On Your Mark ran for seven editions through 2023, produced in partnership over the years with the Biotechnology Innovation Organization, Biocom California, the California Life Sciences Association and Halloran Consulting Group. It became a fixture for the tens of thousands of executives, investors and business development teams who descend on Union Square each January — not for the conference itself, which is invitation-only, but for the roughly fifty satellite conferences, ninety-plus receptions, breakfast panels and partnering forums that have grown up around it.
For 2027, the guide returns in two parts.
onyourmark.bio, a free searchable directory of every event of the week, goes live September 15, 2026 and will be updated daily through the conference itself. Visitors will be able to filter by day, by event type, and by whether an event is open, requires registration, or is invitation-only — and build a personal schedule that exports to their own calendar.
The guide returns as a designed PDF published twice: a planning edition on November 18, 2026, timed for when attendees build their week, and a final edition on January 6, 2027 that carries through the conference. This will be the eighth edition.
"A few years ago, JPM Week outgrew most traditional coverage methods," said Tilton Little, CEO of BigBio Communications and publisher of Big4Bio. "What's changed is that now anyone can generate a list of events in an afternoon — and a lot of what will circulate this December simply won't be accurate as events move, receptions get cancelled, and more. Bringing back On Your Mark in this dynamic way is the solution to all of those issues.”
Every listing on onyourmark.bio will carry the date it was last checked, and events confirmed directly with their organizers will carry a verified mark. The directory will also include receptions — the invitation-only dinners and firm parties that never appear on any official agenda, and which have historically been the most-used section of the guide.
Listing an event is free, whether or not an organization advertises. Submissions are open now at onyourmark.bio.
