Co-marketing swaps with complementary tools
Partner with a non-competing product that shares your ideal customer profile and cross-promote each other to your existing audiences for free.
Why this can grow a startup
Both products already have trust with their audiences, so a recommendation from a complementary tool carries built-in credibility. It is essentially free cross-pollination with no ad spend. Works especially well when both products solve adjacent problems for the same buyer, making the recommendation feel natural rather than promotional.
Company example
Multiple SaaS founders report that co-marketing with adjacent tools (e.g., a CRM partnering with an invoicing tool) drives qualified leads at zero cost.

When to use it
Use this when Email, Partnerships is relevant to pre-launch and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read reddit.com and identify what is directly supported.
- Choose one channel context: Email, Partnerships.
- Define the test around one observable customer behavior.
- Set an owner, evidence window, and stop condition before launch.
