GrowthLimit.com on Why SEO Is a Capital Allocation Decision, Not a Marketing Tactic
Dennis Shirshikov applies a derivatives-trained framework to organic growth investment. He argues that companies that treat SEO as an expense rather than a compounding asset consistently underinvest at the worst time.
NEW YORK, NY, September 15, 2026 -- Dennis Shirshikov, founder of GrowthLimit.com, is outlining a framework for SEO investment from derivatives pricing theory. He completed his M.S. in derivatives pricing under George Courtadon, the inventor of Protected Equity Notes and Reverse Convertibles, and spent years in investment banking at Cantor Fitzgerald before pivoting to organic growth. The mental model that transfers most directly, he says, is how to think about compounding assets.
In that framework, organic search isn't a quarterly marketing line item to optimize. It's a long-term asset: one that produces increasing returns over time, is difficult for competitors to replicate, and continues generating value long after the initial investment. The correct question isn't "what does SEO cost this month" but "what is the expected value of the organic position we're building, discounted to today, and what's the right investment to reach it."
"Most companies treat SEO like paid advertising, a cost that produces traffic. The winning companies treat it like a smart investor treats a compounding position: size the investment, don't cut it during a tough quarter, and give it time to compound."
GrowthLimit.com operates on no-contract, cancel-anytime terms and reports an average client engagement length of 26+ months. Shirshikov says that figure reflects the market's answer to whether the compounding thesis holds: clients who see their organic position building don't cancel, not because a contract prevents it, but because cutting the investment would mean giving up an appreciating asset.
