Best alternatives to GoHalves in 2026

Imagine two apps that both sell to the same kind of customer but aren't rivals — say a project-management tool and an invoicing tool. Each has an email list the other would love to reach, but finding that partner, agreeing on a campaign, and tracking whether it actually worked usually takes weeks of cold emails and spreadsheets. GoHalves automates that whole handshake: it matches brands with compatible audiences, drafts the joint campaign for you, and hands each side a tracked link so both know exactly what the swap delivered. Technically, GoHalves runs on an audience-matching engine that pairs B2B SaaS and AI companies by target-customer overlap rather than by category, then uses AI to draft campaign copy tailored to each brand's voice — newsletter swaps, social shoutouts, in-app placements, deal exchanges, or podcast trades. Each side gets a unique tracked link so results are measured per partner instead of guessed at. The product is in a founding-member phase: free to join, no card required, with a 50% discount locked in for 12 months once paid plans launch. It currently favors companies with at least ~1,000 engaged users, since matching thin audiences produces weak campaigns either way.
