The case I've spent years making

Revenue and authority. Same team, same partners, same channel.

Partnerships drives revenue and authority at the same time, and programs that split them leave most of the value on the table.

The partners who convert and the partners who get cited are increasingly the same people. The best partnership programs aren't wired into the growth motion after the fact. They're built early, built right, and treated as core.

The Partner Contribution Model

Every partner mapped on two axes, so revenue and authority get managed together.

Citation presence

Invest and develop

Citations are working, revenue hasn't caught up. Front their costs. They're building your funnel.

Protect

Strong on both. Don't touch what's working, and make sure you can see why it works.

Cut or restructure

Low on both. Change the brief or exit, and reinvest in the top two.

Watch

Revenue is there, citations are weak. Exposed to the next algorithm update.

How I operate

I don't run programs. I build engines.

Partner strategy, commission and attribution design, and the agent-run systems that keep it all moving.

01

One architecture, not separate programs

One funnel, one set of tiers and one attribution model across every partner type. Separate programs compete for the same partners. One engine compounds.

02

Quality over volume

High-trust, high-expertise partners beat a long list of inactive ones. I pay them on hybrid commissions designed around ROAS and partner LTV.

03

Revenue, not clicks

Every program starts with the business's own KPIs. Onboarding, enablement, tiering and reporting are built to connect partner activity to revenue.

04

Agents run the work, people make the calls

Recruitment, activation and reporting shouldn't wait for a gap in someone's calendar. Agent-run workflows keep a program moving around the clock, with every decision logged and open to review.

05

Relationships, prioritised

Partner relationships, contracts and data belong to the brand, on the brand's own platform. Whoever runs the program brings the method. The results stay with you.

06

High performance without the human cost

I don't think high performance has to cost people their well-being. I build teams where failing fast is survivable, because that's the only way anyone innovates.

Track record

Built from scratch. Built at scale. Building it now.

FAQ

Questions I get asked

What is offsite AEO?

Answer Engine Optimisation is the work of getting your brand cited when buyers ask ChatGPT, Perplexity or Google's AI answers for a recommendation. Offsite means earning those citations on other people's pages: partner content, review sites, forums and creators. Answer engines lean heavily on third-party sources, which makes it a partnerships job.

Why run affiliate and AEO as one program?

Because the partners who convert and the partners who get cited are increasingly the same people. Split them into two programs and you pay twice, negotiate twice and measure twice. One partner base, one set of terms and one attribution model gets you revenue and authority from the same relationships.

What is a hybrid commission model?

A flat fee, a revenue share and a performance bonus in one deal. It pays partners for the authority they bring as well as the customers they send, and it rewards the ones who outperform. I design them around ROAS and partner LTV rather than volume.

When should a SaaS company start a partner program?

Earlier than most do. The best partnership programs aren't wired into the growth motion after the fact. They're built early, built right, and treated as core.
