Biomarker Conference 2027 | Sponsor San Diego & London

Stream 2 series

One biomarker conference series, three dates in 2027

If you sell into biomarker and companion diagnostics teams, the ImmunoMark biomarker conference runs its Stream 2 (Biomarkers & Companion Diagnostics) at every 2027 edition: San Diego in February, London in March and Boston in June. The question for your team is not whether the audience is there, but which edition matches the buyers and the market you are targeting this year.

Stream 2 runs in parallel with Next-Gen Immuno-Oncology, so the room holds biomarker specialists and the IO programme teams who depend on them. The prospectus lists the roles you will meet: Heads and Directors of Translational Medicine, Biomarker Operations Leads, Principal Scientists, and managers working on biomarker discovery and companion diagnostics. Key departments include Biomarker Discovery & Development, Companion Diagnostics, Precision Medicine, Regulatory Affairs and Bioinformatics.

Across the series, the audience is 55–60% biotech and pharma, and 45–50% senior leadership. That matters when you compare biomarker conferences 2027: a vendor needs budget-holders, and most of this room either holds budget or specifies what gets bought.

Planning across editions

Running a two-edition biomarkers conference programme

Vendors who supply assays on both sides of the Atlantic are already asking about pairing editions.

I saw that you are also doing it in the US, so that might be something that we might be interesting to couple both Europe and US because we do provide assays in Europe and in the US.
Matteo Tosolini, Biopharma Business Development Manager EMEA, Hologic Diagenode

If you are weighing several biomarker conferences, compare like with like: Stream 2 audience, meetings included, and the sessions closest to your product. Edition-level detail is on our pages for the biomarker conference in San Diego and the biomarker conference in London. Platform vendors in liquid biopsy, spatial or digital pathology should also read the biomarker technology page. For the European regulatory backdrop, see our IVDR companion diagnostics guide.

What sponsors said

Feedback from London 2026 sponsors

Here is what sponsors told us at our London 2026 launch edition.

We really liked the focus of the event, the topics, the talks, really good opportunity to engage with people, the support we get from you is really great and we appreciate that very much. Based on our experience we would be very interested in also sponsoring the next annual event.

Project Manager

PromoCell GmbH · Sponsor, London 2026

We are always interested in sponsoring interesting conference, based on this years experience, I guess I will manage to get some budget for the next edition.

BD Manager Europe

Secretech · Sponsor, London 2026

Conversations I have had are very high level, the footfalls been great and the kind of research going on around is really life changing. We will be very interested in sponsoring the second annual.

Research Account Manager

Miltenyi Biotec · Sponsor, London 2026

My experience here at Immunomark 2026 has been really great. We benefit from very good logistical organisation. Networking sessions were excellent and we consider Immunomark a strategic conference for the coming years.

Senior Business Development Director Europe

Frequently asked questions

Which ImmunoMark edition is best for a biomarker vendor?

It depends on your market. San Diego (10–11 February 2027) suits vendors targeting US West Coast biotech and diagnostics teams and wanting launch-edition visibility. London (3–4 March 2027) has a 2026 track record and a delegate base that is 60% UK & Ireland and 40% rest of Europe. Boston is in June 2027.

Can our talk be placed in the biomarker stream rather than across both streams?

Yes. Platinum, Gold and Silver sponsors choose their stream, so you can place your talk in Stream 2: Biomarkers & Companion Diagnostics. The Headline package is different: its 30-minute Day 1 keynote slot runs across both streams.

How do we make sure our 1:1 meetings are with biomarker leads?

You choose them. The full delegate list with profiles is sent 10 days before the event, and your team selects who to meet in pre-scheduled 20-minute meetings. The wishlist feature lets you flag priority contacts.

Is San Diego a riskier choice because it is a launch edition?

It is a first edition, so there are no past results for that city. The format and packages are the same as London, where the 2026 edition delivered 200+ meetings and 15–25 meetings per sponsor. In San Diego, 300+ senior attendees are expected, and early sponsors have less competition for visibility.

Can we sponsor San Diego and London together?

Yes. Packages are the same at both, and the events are three weeks apart, so one set of materials and one meeting plan can cover both. A common split is Platinum in Stream 2 at your primary edition and Gold or Exclusive 1:1 Meetings at the second.
