Chicago-based William Blair on Monday announced it has acquired Armentum Partners, a boutique debt and alternative capital solutions advisory firm, in a deal that broadens the investment bank’s capabilities in the venture capital ecosystem.
The acquisition marks William Blair’s second investment banking deal of the year and adds expertise in enterprise value lending, asset-based lending and royalty monetization, according to a company news release.
“We continue to invest in capabilities and teammates who can provide differentiated outcomes for our clients across the venture capital, public company, and collegiate communities,” Matt Zimmer, global head of investment banking at William Blair, said in the release.
Armentum Partners, founded on expertise in the healthcare and technology sectors, advises venture-backed businesses, public companies and academic institutions on capital solutions. The firm has raised more than $22 billion across 390 transactions since its founding. Its professionals are based in Boston, Chicago, Menlo Park, New York, Philadelphia and San Francisco, serving clients in the United States and Europe.
As part of the transaction, William Blair will open an office in Menlo Park, establishing a presence in Silicon Valley. All Armentum Partners professionals are expected to join William Blair, preserving their relationships and specialized expertise.
“This is a natural synergistic extension of our capital markets strategy,” Steve Maletzky, head of capital markets at William Blair, said. “Enterprise value lending is a specialized discipline, financing companies against the value of their assets, often before traditional cash flows exist. Armentum Partners has built a leading franchise advising many of the most well-known and innovative public companies, universities and venture-backed businesses.”
Hutch Corbett of Armentum said joining William Blair will expand the range of services available to clients. “We built our firm with a dedicated focus on our clients, offering them access to our deep market relationships and expertise in delivering bespoke solutions,” Corbett said. “Joining William Blair unlocks opportunities for our clients, providing the increased scale, reach, and sector depth of a premier global platform along with relationship and execution continuity.”
The deal comes as private credit and direct lending markets expand rapidly. Venture-backed and public companies have increasingly turned to flexible, non-dilutive capital to fund growth in healthcare innovation, artificial intelligence, software, fintech and industrial technology. Demand has been especially strong among later-stage technology companies and biopharmaceutical firms financing clinical trials and commercialization, segments where William Blair has been building its presence.
William Blair’s recent growth in life sciences includes the addition of Michael Allwin as head of biopharma investment banking, Emanuela Branchetti as managing director of scientific affairs and Alethia Young in equity research.
Armentum Partners will continue to operate under its own name for a period after the closing. Clearsight Advisors served as financial advisor to Armentum in connection with the transaction.
William Blair is an employee-owned firm with expertise in investment banking, investment management and private wealth management. Together with its strategic partners, it operates in more than 30 offices worldwide, including alliances with Allier Capital, BDA Partners and Poalim Equity Ltd.
The firm’s investment banking group has advised on more than $880 billion in completed transaction volume from July 2021 through June 2026, according to the release.
