Co-Managing Partners Josh Bonnie, Rajib Chanda, and Jeff Knox credit the success to “talent availability”: Unlike New York’s cutthroat market, D.C. offers top corporate minds untapped by policy giants.

Key drivers:

• Deal Flow Magnet: The office handles 40% of Simpson’s cross-border M&A, advising on $100 billion in transactions last year, from Zeekr’s NYSE IPO to KKR’s £1.6 billion Assura bid.
• Strategic Hires: Lateral pulls like a Kirkland alum for private equity in 2024, focusing on funds work without diluting corporate focus.
• Hybrid Model: Blending D.C.’s regulatory adjacency with New York’s deal engine, sans full lobbying pivot.

This approach yields: The firm’s global revenue hit $2.9 billion in 2025, with D.C. contributing 10%—up from 5% in 2020—while PPP soared to $6.43 million.

Knox echoed: “Talent flows to us because we offer deal excitement without the policy grind.” On LinkedIn, alumni praise the “entrepreneurial vibe,” with one ex-partner posting: “Simpson’s DC play is smart—corporate depth in a reg-heavy town sets you apart.”
