FAQs
What qualifies a firm as “Boston-based” in this list?
We prioritize firms with Boston headquarters. Some global platforms have Boston as a major office. Where a firm’s global HQ is elsewhere, we note Boston as an office.
How are “number of investments” and “number of exits” defined?
Totals vary by source and methodology. Some include platform, add-on, and follow-on deals, while others count only platforms. Exits may include IPOs, secondary sales, and trade sales.
Why might counts differ across databases?
Each tracker applies its own inclusion rules and cut-off dates. Real estate transactions and private credit repayments are often excluded from PE/VC databases.
Do these firms buy online businesses and SaaS companies?
Many Boston firms invest in software and tech-enabled services. If your business has traction, recurring revenue, and clean financials, PE interest is possible.
Will a PE firm require majority control?
Often yes for classic buyouts, but growth equity investors may take minority positions. It depends on the firm’s mandate and the deal thesis.
What is the typical holding period?
Most PE firms target three to seven years, though long-duration and permanent-capital vehicles can hold longer.
How should I approach a PE firm?
Prepare a short teaser, a clean CIM, historical and forecast financials, cohort and retention metrics, and a clear growth plan. Be ready to discuss use of proceeds and risks.
What sectors are most active in Boston PE?
Software and tech-enabled services, healthcare, business services, industrial technology, and energy infrastructure feature prominently.
Does inclusion here imply endorsement?
No. This list is informative. You should conduct your own due diligence on any prospective investor.
How can I get my company in front of these buyers?
Start with a free valuation to benchmark price and readiness, then market through curated buyer networks and processes that attract PE interest.
