Grow Theory exists to do marketing the right way: measured in revenue, priced on results, and honest about what's working and what isn't.

why grow theory exists

I've watched the tricks from the other side of the table.

For years, I worked with and around the vendors businesses rely on to grow. I've talked to dozens of agencies. Some were great. Most had the same playbook: lock you in, send a monthly report full of impressions and clicks, and get paid no matter what happens to your revenue.

I started Grow Theory to do things right. Every campaign is measured in revenue, not activity. Every result is tracked back to the dollar. And for advertising, I don't charge a big monthly fee. I take a share of the revenue the ads bring in.

That's not a gimmick. It's confidence. If I can't grow your revenue, I don't deserve to get paid for your ads.

When I'm not growing revenue for clients, you'll find me on the golf course.

What's in a name.

grow the·o·ry /ɡroʊ ˈθɪr.i/ noun

1.The belief that marketing, run like a science, makes revenue compound.

2.A marketing agency that runs advertising, SEO and web design as one system, accountable to a single number: revenue.

Origin: from grow, to increase in size or value, and theory, an idea tested against evidence until it holds up.

What we do differently.

Paid on revenue

Our advertising fees are a share of the revenue we bring in. SEO and websites are flat rates, quoted upfront.

Measured in dollars

Every report starts with revenue. Impressions and clicks only show up if they explain it.

Fix the sales process first

We fix what happens after someone clicks before we spend your money sending people to it.

Let's talk about your number.
