Co-marketing is the practice of two companies collaborating on marketing activities to reach a larger audience than either could access alone. Common co-marketing activities include joint webinars, co-authored content, shared event sponsorships, co-branded landing pages, and joint case studies.
Co-marketing works because it gives each company access to the other's audience. A PRM vendor co-hosting a webinar with a CRM platform reaches CRM users who might need partner management. The CRM platform reaches PRM users who might upgrade their CRM. Both audiences are relevant to both companies.
Effective co-marketing requires audience alignment and equitable effort. The best campaigns feature complementary brands with overlapping buyer personas but non-competing products. When both companies promote equally, the combined reach can be three to five times what either achieves alone.
Many vendor partner programs fund co-marketing through Market Development Funds (MDF). Partners submit marketing plans, receive funding, execute the campaign, and report results. This structure ensures marketing spend aligns with the vendor's messaging while leveraging the partner's local market knowledge.
The biggest failure mode in co-marketing is unequal commitment. One company promotes heavily while the other does the minimum. Successful co-marketing requires a shared campaign plan, mutual promotion commitments, and shared metrics for measuring success.
