Massumi + Consoli Opens Silicon Valley Office, Hires PE Partner Matt Stewart

Massumi + Consoli will open a Silicon Valley office in Palo Alto after hiring private equity and M&A partner Matt Stewart from Weil, Gotshal & Manges.

Stewart brings more than 20 years of experience advising private equity sponsors and strategic buyers on domestic and cross-border transactions. His client roster includes Advent International, BlackRock, Khosla Ventures, Norwest Venture Partners, TPG, and Trive Capital. Those relationships span growth equity, buyouts, venture capital, and other private-market strategies.

The move puts the law firm inside a major hub for technology transactions, private capital, and strategic acquisitions. Stewart is expected to join in the coming weeks.

Why did Stewart choose this firm?

Stewart said the firm's operating model drove his decision. Massumi + Consoli pairs partner-led legal service with technology, data, artificial intelligence, and specialized operational support.

The firm runs that infrastructure through ElevenHundred+, a management services organization it launched to build and operate its business, technology, and administrative backbone. The firm argues this structure gives lawyers access to resources normally found only at larger firms while fixing operational and retention problems that plague traditional partnerships.

Stewart put it bluntly.

"Exceptional client outcomes is non-negotiable for me. My clients will be well-served at M+C," Stewart said. "Further, the firm's partnership with ElevenHundred+ addresses many of the issues destabilizing some of the larger law firms. It provides resources to grow the firm in a sustainable way while mitigating partner attrition. It's a game-changer for our industry. It will deliver substantial value for clients. I'm thrilled to be a part of it."

What does the hire signal?

Co-founder Peter Massumi framed the hire as proof the firm can win talent against bigger rivals. He noted Stewart had other options.

"The caliber of partners we're attracting speaks to the strength of our platform and the opportunities ahead. Matt Stewart is the most recent example. He built a leading private equity practice," Massumi said. "He had compelling opportunities to join some of the largest firms in the country. But he chose M+C because, in his words, this is the best platform to serve his clients. That's a strong endorsement of what we've built so far and what we intend on building together."

Co-founder Anthony Consoli called the expansion a deliberate step, not a symbolic one.

"Expanding our presence in the Silicon Valley is a significant step for our firm and a natural extension of our private equity and M&A practice," Consoli said. "We wanted to grow here with an exceptional lawyer who has the experience, relationships and reputation to help us build a meaningful presence. Matt brings all of that, and we're excited about what we can build together."

The firm expects Stewart's track record to produce a substantive regional practice rather than a nominal office.

What comes next?

The Silicon Valley launch follows a stretch of senior partner appointments across the firm's national platform, including a recent Orange County office opening. Massumi + Consoli positions itself as a modern alternative for middle-market private equity firms and acquisitive companies.

Stewart's arrival expands the firm's capacity to advise on acquisitions, dispositions, growth investments, leveraged buyouts, joint ventures, and other strategic transactions. The bet now is that proximity to technology companies, venture investors, sponsors, founders, and strategic acquirers converts Stewart's relationships into deal flow.
