Similarweb has appointed Eran Lefler as Chief Operating Officer (COO), strengthening its executive leadership as the company continues expanding its AI-powered digital intelligence platform and global operations.
Eran joins Similarweb following an 11-year tenure as Chief Operating Officer at AppsFlyer, where he helped scale the business from an early-stage startup into a company generating more than $500 million in annual recurring revenue (ARR). His appointment brings deep operational expertise at a time when Similarweb is investing heavily in artificial intelligence, proprietary data, and enterprise growth.
Bringing Operational Leadership to the AI Era
For Eran, joining Similarweb represents an opportunity to build on a strong foundation while helping shape the company's next phase of innovation.
Sharing the news on LinkedIn, Eran reflected on his journey at AppsFlyer, thanking colleagues for more than a decade of growth and collaboration. While describing the move as the beginning of a new chapter, he highlighted Similarweb's unique position in the market, pointing to its rich proprietary digital intelligence data as a key reason for joining.
He believes the combination of proprietary data and artificial intelligence presents a significant opportunity to transform not only how businesses understand digital markets but also how Similarweb operates internally and executes its go-to-market strategy.
Unlocking the Value of Data and AI
As Chief Operating Officer, Eran will oversee Similarweb's operational strategy, helping the company scale its business while embedding AI more deeply across its operations and commercial organization.
His appointment comes as enterprises increasingly rely on digital intelligence platforms to better understand customer behavior, market dynamics, competitive performance, and emerging opportunities. At the same time, AI is changing how organizations analyze data, automate workflows, and make strategic decisions.
Eran sees these trends converging at Similarweb. By combining one of the industry's largest proprietary digital datasets with AI-powered capabilities, the company is well positioned to help customers make faster, more informed business decisions while improving operational efficiency across its own organization.
Leading the Next Phase of Growth
Eran's experience scaling high-growth technology companies aligns with Similarweb's ambitions to expand its market presence and deepen customer value.
Having led operations through years of rapid growth at AppsFlyer, he brings expertise in building scalable organizations, aligning cross-functional teams, and driving disciplined execution. Those capabilities will be instrumental as Similarweb continues investing in product innovation, AI, and global expansion.
His appointment reflects a broader trend across enterprise technology, where operational leaders are increasingly expected to combine business strategy with AI-driven transformation. As organizations seek to turn data into competitive advantage, leaders who can integrate technology, operations, and commercial execution are becoming essential.
Looking ahead, Eran expressed his excitement about joining the Similarweb team and contributing to the company's next chapter of growth, powered by data, AI, and innovation.
