Massumi + Consoli
Anthony Consoli and Peter Massumi founded the firm in 2013, stepping away from the institutional scale of Kirkland & Ellis to build a specialist private equity and M&A practice. The firm emerged with a clear thesis: middle-market sponsors and growth-stage investors need transaction counsel that can operate with the sophistication of Big Law but the commercial pragmatism and speed of a dedicated boutique. From inception, the firm's identity has been shaped by a single-minded focus on private capital — a constraint most competitors are unwilling to accept, but one that creates a sharp structural alignment with the buyout funds, growth equity shops, and venture firms that form its client base. The firm advises private equity sponsors, venture capital funds, independent sponsors, and family offices on platform and add-on acquisitions, leveraged buyouts, growth equity investments, and portfolio company exits. Its deal sheet spans sectors including technology, healthcare, business services, and consumer, with a geographic footprint that consistently reaches across the US, Canada, and Western Europe. Representative engagements include complex cross-border carve-outs and serial add-on programs for established lower-middle-market and middle-market funds. The firm also handles fund formation and GP-level structuring work, a natural adjacency that deepens its integration into the sponsor lifecycle. With offices in Los Angeles and later expansion into Texas, the firm has deliberately avoided the coastal density trap that drives up billing rates. It fields roughly 25 to 35 lawyers, according to legal directories, and recruits heavily from peer firms with strong private equity benches — a model that keeps leverage ratios low on deal teams. May 2024: The firm added a partner in Texas to support growing sponsor demand in the energy and infrastructure sectors (public record). Philanthropic or adjacent operating vehicles are not publicly disclosed. Massumi + Consoli occupies a structural niche that is increasingly hard to replicate. It is not a full-service firm that happens to have a PE group. It is not a lifestyle practice for retiring partners. It is a pure-play private capital law firm — and the discipline of that focus means the firm's incentives, staffing model, and conflict check process are all built around the rhythms of deal work and sponsor relationships, a posture that positions it differently from both the global law factories and the generalist mid-market firms that compete for the same clients.

Frequently asked questions
What type of clients does Massumi + Consoli primarily serve?
The firm concentrates on private equity sponsors, venture capital funds, independent sponsors, and family offices. Its practice is purpose-built for buyout shops, growth equity investors, and firms executing platform and add-on strategies. The firm does not maintain a general corporate or litigation practice that dilutes this focus.
Who runs the firm's day-to-day deal practice?
Co-founders Peter Massumi and Anthony Consoli remain the firm's named partners and lead the deal practice. Both trained at Kirkland & Ellis before launching the boutique in 2013. The firm operates with a low-leverage staffing model, meaning senior partners are directly involved in transaction execution.
Does Massumi + Consoli handle fund formation work?
Yes. In addition to buy-side and sell-side M&A, the firm advises sponsors on fund formation, GP-level structuring, and internal governance matters. This dual capability — deal work plus fund structuring — is a deliberate complement that aligns the firm with the sponsor across the full investment lifecycle.
How does the firm's geographic footprint affect its deal coverage?
The Los Angeles headquarters and a Texas office position the firm outside the highest-cost legal markets while still covering cross-border sponsor work across the US, Canada, and Western Europe. The Texas presence, expanded in 2024, supports energy and infrastructure transactions alongside the firm's core technology and healthcare verticals.
What distinguishes Massumi + Consoli from a general mid-market law firm?
The firm accepts a self-imposed constraint: it only does private capital work. It does not run litigation, employment, real estate, or trusts and estates departments. That narrowness means its staffing, pricing, and conflict-check architecture are all optimized around sponsor-driven deal timelines, creating a materially different client experience than a full-service firm can offer.
