If you’ve ever found yourself wondering about the brilliant minds shaping the digital marketing world, you’ve probably heard of Semrush. And at the heart of Semrush’s incredible journey, for a very long time, was its co-founder, Oleg Shchegolev. He’s someone who really transformed the way businesses approach online visibility, and his story is a fantastic example of turning a keen interest into a global powerhouse. While he recently stepped into a new role, shifting from CEO to Chief Technology Officer in March 2025, his influence on Semrush remains absolutely central. We’re going to pull back the curtain on Oleg’s journey, from his early days fiddling with SEO tools to leading Semrush through its incredible growth, including its successful public listing, and now focusing on the company’s technological future, especially in AI. We’ll trace how his vision, backed by a dedicated team, built Semrush into the comprehensive digital marketing platform it is today, trusted by millions worldwide.
Who is Oleg Shchegolev?
To really grasp the story of Semrush, you have to start with the man himself: Oleg Shchegolev. Oleg isn’t just a corporate figure. he’s a tech enthusiast with a deep passion for digital innovation. He got his Engineer’s degree in Computer and Information Systems Security/Information Assurance from Peter the Great St. Petersburg Polytechnic University, attending from 1997 to 2003. That background in IT engineering laid a solid foundation for everything that came next.
Early in his career, Oleg dove headfirst into the internet marketing scene. He started out as an SEO Manager at Strider, then moved on to serve as the COCEO of tirnet.ru, and even co-founded efind.ru. These early experiences weren’t just jobs. they were stepping stones, giving him a front-row seat to the world of online visibility and competitive analysis. You could say he was bitten by the SEO bug pretty early on, around 2000 actually. His journey shows someone who was always learning, experimenting, and seeing how technology could make online competition more transparent and, ultimately, fairer for everyone.
The Spark: From Seodigger to SEOquake
You know how some of the best ideas often start as personal projects? That’s exactly what happened with Semrush. Back in 2006, Oleg Shchegolev and his childhood friend, Dmitry Melnikov, were just two guys with a shared passion for SEO and new technologies. They started working on a tool for their own use, something to help them understand SEO and online strategies better. They called this initial creation “Seodigger”.
This wasn’t some grand business plan from the get-go. it was more about curiosity and problem-solving for themselves. By 2007, this personal tool had evolved and was renamed “SEOquake,” becoming a Firefox extension. It was a hit, quickly becoming one of the most popular SEO toolbars with millions of browser installations. They shared it with friends, then friends of friends, and soon, a whole network of people in the IT industry were using it and giving feedback.
Oleg and Dmitry weren’t just sitting back. they kept adding new features and testing the tool, making it even more user-friendly and popular. Oleg himself mentioned that in the beginning, there wasn’t an “intricate and elaborate plan” for how to develop the product or conquer the market. It was a lot of experimentation, driven by their own satisfaction with the tool. This hands-on, user-first approach became a core part of their philosophy. The success of SEOquake really showed them that there was a huge demand for powerful, accessible SEO tools, and it gave them the push they needed to think bigger.

Founding Semrush: A Vision for Transparent Competition
Building on the success and insights from SEOquake, Oleg Shchegolev and Dmitry Melnikov decided to take their vision to the next level. In 2008, Semrush was officially established. Their core mission was clear: to make online competition fair and transparent, giving everyone equal opportunities. They saw a gap in the market for accessible data and tools that could truly empower marketers to navigate the ever-changing online world.
Starting a business is tough, and launching one in 2008, right in the middle of the global financial crisis, was especially challenging. Semrush began with just a couple of tools and minimal features, with their friends as the very first customers. Funding was a real uphill battle in those early days. But here’s a mind-blowing fact: the company grew without raising any external funds until 2018!. That’s right, for a decade, they bootstrapped their way to success, showing just how committed Oleg and Dmitry were to their original vision. In April 2018, they finally accepted $40 million in funding from venture capital firms like Greycroft, E.ventures, and Siguler Guff, not because they desperately needed the money they were already profitable, but for the strategic partnerships those investors brought.
This initial period was all about laying the groundwork, focusing on solving real problems for marketers, and building a product they themselves would love to use. They knew that if they could make online presence and website improvement easier, businesses would naturally thrive alongside Semrush. This clear vision, combined with their dedication, quickly established Semrush as a trusted source for SEO competitive analysis and market insights.

Semrush’s Ascent: Growth and Innovation Under Oleg’s Leadership
Under Oleg Shchegolev’s leadership, Semrush didn’t just grow. it absolutely soared. It quickly transitioned from being a niche SEO tool to a comprehensive suite that covers pretty much everything a digital marketer needs. Think about it: they started with just two tools, and by 2012, they had four. That number jumped to eight by 2014, and an incredible 50 tools by 2020. Today, Semrush offers over 55 tools, products, and add-ons designed to manage online visibility and accelerate digital growth.
This expansion wasn’t accidental. It was a strategic move to provide an all-in-one platform for SEO, PPC, content marketing, social media, and competitive research. Oleg’s vision was always to make online marketing easy and accessible, and that meant continuously innovating and adding more value to the platform.
Semrush hit some significant milestones along the way. In 2012, it officially registered as a U.S. company and opened its first U.S. office near Philadelphia, Pennsylvania. By 2013, they established a dedicated marketing department, moving beyond just word-of-mouth growth. Global expansion was also a priority, with offices opening in Prague and Limassol in 2015, and a new Boston HQ established in 2018.
One of the biggest moments in Semrush’s history was its Initial Public Offering IPO on the New York Stock Exchange NYSE on March 24, 2021, trading under the symbol NYSE: SEMR. This move solidified the company’s position as a major player in the digital marketing technology space. The S-1 filing revealed impressive figures: sales of $213 million and over 82,000 customers at the time.
The growth trajectory continued upward. By 2023, Semrush had grown to over $330 million in annual recurring revenue ARR, with more than 100,000 paying customers and 850,000 free users. The full year 2024 revenue reached $376.8 million, with quarterly revenue growth of 21.77% in Q2 2024. As of today, Semrush serves a vast global user base of over 10 million digital marketers in about 143 countries. Semrush Stock Price: What’s the Deal with SEMR?

They acquired Prowly in 2020, a PR and media relations SaaS platform, expanding their presence in Poland. In 2021, they acquired Backlinko, a popular marketing and SEO training platform. More recently, in March 2024, they acquired assets of Datos, aiming to integrate audience intelligence tools, and in July 2024, they acquired Ryte, a German SaaS company specializing in website quality management and SEO optimization. These moves show a clear commitment to providing a comprehensive, cutting-edge solution for marketers worldwide.
