An AI-native partnerships firm

Additive builds trust-based partnerships where both sides add more value than they extract.

The strongest partnerships go well beyond referral fees. They're built on shared goals, create value for both sides, and show leadership exactly what they deliver.

That's what we build, for companies that want partnerships to become a real growth channel.

We're AI-native by design. Our own AI agents do the heavy lifting behind the scenes, so senior time goes into the part no agent can do: building trust.
