Co-Marketing

A collaboration between two or more brands to jointly promote complementary products or services to each other's audiences, sharing the cost and amplifying the reach of both parties.

Co-marketing doubles audience reach without doubling budget. When brands are genuinely complementary rather than competitive, the audience of each instantly trusts the other through association, making acquisition far cheaper than cold advertising.

A founder who teaches business skills for coaches partners with a website designer who builds coach websites. They co-host a free webinar, cross-promote to each other's email lists, and create a bundled offer. Both founders acquire new clients they would not have reached independently.
