What is a Co-Marketing Webinar?
A co-marketing webinar is a joint webinar run by two or more non-competing brands that serve a similar audience. Each partner promotes the event to its own list, the presenters split the content, and the leads are shared based on an agreement set before the event.
The appeal is simple math. Two brands with 5,000 contacts each can put the same session in front of 10,000 people while splitting the production effort. The best partnerships pair complementary products, such as a CRM vendor and an email tool, so both audiences find the topic genuinely useful.
Key characteristics
- Shared audience: Each partner promotes to its own list, expanding total reach.
- Split costs: Production, promotion, and platform fees are divided.
- Agreed lead split: Both sides decide upfront how registrants and leads are shared.
- Co-promotion: Partners run joint webinar promotion across both channels.
Why Co-Marketing Webinars Matter for B2B Marketers in 2026
Audience growth is slow and paid reach keeps getting more expensive. A co-marketing webinar borrows a partner's trusted audience, which is far cheaper than buying that reach with ads.
Problems it solves
- Small audience: You tap a partner's list instead of relying only on yours.
- Rising acquisition cost: Shared promotion lowers the cost per registrant for both sides.
- Limited authority: Pairing with a respected brand adds credibility to your demand-gen motion.
Real-World Examples
Complementary tools
A project management app and a time-tracking tool co-host a productivity session, then split the 1,200 registrants evenly and feed them into separate nurture tracks.
Vendor and agency
A software vendor partners with an implementation agency so each reaches the other's clients, and the agency repurposes the recording for its own content team.
Industry association tie-up
A brand co-hosts with an industry association to borrow its credibility and member list, generating warmer leads than cold outreach would.

Frequently Asked Questions
The most common approach is to share all registrants with both partners, since each contact opted in through the joint event. Agree on the split, data handling, and follow-up rules in writing before you promote, so there are no disputes afterward.
Look for brands that serve your audience but do not compete with you, such as adjacent tools or service providers. The strongest partnerships have similar audience sizes so neither side feels like it is carrying the promotion.
Responsibilities are usually split, with one partner often owning the platform and registration while both contribute speakers and promotion. Define ownership of each task early so nothing falls through the cracks.
For most B2B teams, yes, because the combined reach and shared cost outweigh the extra planning. The key is choosing a partner whose audience genuinely overlaps with yours so the leads are relevant.
Be transparent on the registration page that both brands will receive the contact details, and make sure your consent language covers it. Following the relevant privacy rules upfront protects both partners and keeps the leads usable.
