Chainalysis made co-founder Jonathan Levin its CEO in December 2024, after founding CEO Michael Gronager’s temporary leave became a permanent departure. The company said Gronager stepped down from his executive role and board seat; TechCrunch reported that he retained his equity. The public statements do not give a more specific reason for his exit.
What changed at Chainalysis
On October 7, 2024, TechCrunch reported that Gronager was on a personal leave of absence, which Chainalysis then described as temporary. President and COO Sari Granat was serving as interim CEO. About two months later, TechCrunch reported that Gronager had agreed to leave permanently and that the board had appointed co-founder Jonathan Levin to the CEO role. TechCrunch’s December 2024 report described the timing; Chainalysis’s announcement confirmed the succession and role changes.
| Person | Role in the transition |
|---|---|
| Michael Gronager | Co-founder and outgoing CEO; stepped down from the company role and board seat. TechCrunch reported that he retained his equity. |
| Jonathan Levin | Co-founder who succeeded Gronager as CEO. Chainalysis’s current company page lists him as Co-Founder and CEO. |
| Sari Granat | Served as interim CEO during Gronager’s leave, then returned to her President and COO roles, according to Chainalysis. |
Why did Michael Gronager leave?
The public explanation is broad, not detailed. Chainalysis described the permanent departure as an agreement between Gronager and the board, without specifying a personal or board-level reason. Gronager offered his own perspective in a public post: “After much thought, I’ve decided it’s the right time for me to explore new opportunities and contribute in new ways.” That statement explains how he characterized his decision; it does not independently describe the board’s deliberations.
TechCrunch reported that Levin declined to provide more information about Gronager. The cited reporting and company statements do not establish a dispute, firing, health issue, or other specific cause, so none should be treated as fact. Gronager’s public post is his own account.

What the transition does—and does not—mean
Gronager’s departure from the board should not be confused with a sale or forfeiture of his ownership: TechCrunch reported that he retained his equity. That does not mean he remained an executive or board member. The company’s current leadership listing identifies Levin as CEO.
Chainalysis’s financing figures sometimes cited alongside the leadership change are historical. TechCrunch reported a $175 million funding round and an $8.6 billion investor valuation in 2022. It also quoted Levin saying in 2024 that the company did not need to raise capital and felt strong about its cash position at that time. These are not disclosures of Chainalysis’s current valuation or financial position.
