INDEX / AGENCY
Pay-for-Performance CRO Agency
A conversion rate optimization agency that takes a percentage of incremental revenue generated from improving ecommerce or SaaS conversion rates, charging nothing upfront.
01 THE IDEA
Instead of charging monthly retainer fees, this agency identifies e-commerce or SaaS companies with measurable conversion rate problems, runs A/B tests and UX improvements, and takes 10% of the incremental revenue generated. If a site converts at 1% and you lift it to 2%, on $25M in revenue that's a $25M gain — a 10% cut is $2.5M, a compelling outcome for both sides.
This model requires strong analytical and CRO execution skills but has an extremely compelling value proposition: zero risk for the client, infinite upside for the agency. AI tools now dramatically accelerate the test-design and analysis cycle, letting a small team run more experiments across more clients simultaneously. The key moat is a proprietary playbook of what works by industry vertical.

03 THE VERDICT
The performance pricing model is a genuine moat because most agencies won't take the revenue risk — it filters for the best operators. The math works handsomely at scale and the client acquisition pitch practically sells itself. Main risk is client attribution disputes, which smart contracts or agreed-upon measurement frameworks can mitigate. High ceiling, low floor on startup costs.
