Growth Limit is a full-stack SEO and digital growth studio based in Ithaca, NY. One founder, top-1% specialists, and a decade of proof.
































































See how our customers hit their Growth Limit.
We were struggling as a business with paid ads to get higher conversions. We were able to reduce our budget, switch to primarily organic and increase conversion rate significantly, scaling without hiring more sales people.

Since starting two years ago we have been able to aggressively expand to new markets by building our lead funnels before investing in infrastructure. This significantly reduced our risk and we are targeting all 50 states soon.
Our industry has a 9-12 month sales cycle and most of our time was spent finding new deals. Since starting with the team 6 of our 7 largest deals this year have been inbound from GrowthLimit efforts.
After hitting our GrowthLimit with our core business, we've since expanded into 4 additional business segments to capture more customers and fund expansion. Would be impossible without the GrowthLimit team.

Dennis Shirshikov isn't a marketer who learned SEO. He's a finance professional, economist, and derivatives-trained analyst who built an unparalleled track record in organic growth — and then built a company around it.
His career spans high-pedigree financial media (Investopedia, Seeking Alpha), high-growth startups (Awning, Summer, GenerationLab), and non-profit institutions (GAARP, New York Botanical Gardens). In every context the result was the same: organic channels built from the ground up that became the primary revenue driver.

In every context the result was the same: organic channels built from the ground up that became the primary revenue driver.
His academic background is what makes his strategic approach different. A Master's in derivatives pricing under George Courtadon — the inventor of Protected Equity Notes and Reverse Convertibles — trained Dennis to think in terms of risk, probability, and expected value. He applies that same framework to every SEO investment decision.
Today he teaches undergraduate accounting, finance, and economics using the Harvard Business School case study method, and runs Growth Limit out of Ithaca, NY. He is also known online as @dennistheprofessor, where he produces long-form investigative financial education content.
