William Blair adds fintech veteran Rishi Sethi in London

William Blair announced that veteran fintech banker Rishi Sethi has joined the firm as a managing director in London, expanding its European technology investment‑banking coverage【3】.

The hire comes as banks race to rebuild sector‑focused teams ahead of what insiders expect to be a resurgence in fintech transactions, including consolidation deals, infrastructure upgrades and private‑capital financing. By adding Sethi, whose background spans several fintech advisory assignments, William Blair aims to deepen its expertise and capture a larger share of the competitive advisory market in Europe.

Sethi’s appointment signals the firm’s intent to lean into the growing fintech ecosystem, where recent years have seen heightened activity in digital payments, neobanking and regulatory‑driven modernization. As rivals bolster their own fintech desks, William Blair’s move underscores a strategic bet that the sector will generate a steady pipeline of high‑value mandates.

The London office, already a hub for the firm’s European operations, will now have a dedicated senior banker to service fintech clients seeking both merger‑type advice and capital‑raising support. This aligns with William Blair’s broader push to strengthen its technology advisory footprint across the continent.

If fintech deal flow picks up as anticipated, the new hire could position William Blair to win a meaningful slice of advisory fees, while also testing the firm’s ability to compete with larger banks that have long dominated the space. The market will be watching whether Sethi’s experience translates into tangible win‑rate improvements for the firm’s fintech practice.
