Selling your tech company, acquiring a Bay Area target, raising growth equity, or running a strategic carve-out? San Francisco is the U.S. center of technology M&A. The firms below structure venture-backed exits, strategic acquisitions, PE-backed roll-ups, and cross-border deals every week — from $10M asset sales to multi-billion-dollar public-company transactions.
Updated April 26, 2026
Bay Area founders, boards, and PE sponsors retain M&A counsel for four recurring reasons: a strategic acquirer (often a public tech company) has signed an LOI to buy the company; a PE-backed platform has identified a Bay Area add-on target; the company is raising a late-stage round large enough to feel like a partial sale (Series D, secondary, structured equity); or a strategic carve-out is being structured for spin or sale.
San Francisco's M&A market splits along two axes. By deal size: top-tier BigLaw — Wilson Sonsini, Cooley, Fenwick & West, Latham & Watkins, Skadden, Kirkland, Paul Hastings — handles the largest, most complex, and most contested deals (mega-cap PE, public-company combinations, hostile situations, complex carve-outs). Middle-market and lower middle-market deals run efficiently at Coblentz Patch Duffy & Bass, Morrison Foerster, Pillsbury, Orrick, Goodwin Procter SF, and specialty boutiques like Grellas Shah for founder-led tech companies.
By industry: technology is the dominant sector (SaaS, cybersecurity, fintech, AI/ML, devtools), with substantial healthcare/life sciences, climate tech, and consumer activity. SF M&A counsel typically have deep sector experience that informs deal structure — earnout milestones in healthcare differ materially from SaaS; PHI/data privacy reps in healthtech are sui generis; open-source IP diligence in devtools is its own discipline.
Critical early decisions in any SF deal: stock vs asset structure; cash vs stock vs hybrid consideration with rollover equity; reps and warranties insurance vs traditional indemnity (now standard in middle-market); HSR antitrust filing; CFIUS review for any foreign acquirer (mandatory for sensitive tech and personal data); California qualification and Section 1101.1 reorganization tax planning; and 280G golden parachute analysis for founder/exec payouts. Engage SF M&A counsel at the LOI stage — economic structure is hardest to change after the term sheet.

Mega-cap and public company ($1B+). Wilson Sonsini, Cooley, Latham, Skadden, Kirkland, Paul Hastings rates. $2.8M-$14M+ per side is normal. RWI broker fees and HSR filing fees additional.
Add-ons. Reps and warranties insurance premium: 2.5-4.5% of policy limits. HSR filing fee: $30,000-$280,000 depending on deal size. CFIUS filing fee: tiered, up to $300,000 for filings requiring full review.
LOI signed: typically 3-5 weeks of pre-LOI negotiation. Bay Area tech deals often have multiple bidders and competing LOIs.
Due diligence: 4-9 weeks in parallel with definitive agreement drafting. Quality-of-earnings, IP (often heaviest in SF tech deals), employment, tax, open-source, and data-privacy diligence run on parallel workstreams.
Definitive agreements drafted, negotiated, signed: 3-7 weeks from LOI for a clean middle-market deal. RWI-driven negotiation and complex carve-outs extend timelines.
Regulatory clearance: HSR 30-day waiting period (with possible second request). CFIUS reviews can extend an additional 45-90 days — and SF tech deals trigger CFIUS more often than other markets because of sensitive technology and data.
Closing to integration: closing usually happens 1-7 days after regulatory clearance. Most modern Bay Area closings are remote signings.
