Boston Meridian Partners is a cybersecurity-focused M&A advisory and capital-raising firm founded in 2004 by John Siracuse and C. Garrett Palm.
Boston Meridian Partners
John Siracuse and C. Garrett Palm founded Boston Meridian Partners in 2004 after careers at major Wall Street firms. The firm does not disclose its own wealth origin, as it raises capital for clients rather than investing proprietary family or institutional capital. Its team includes former technology founders, operators, and venture/private equity professionals alongside investment bankers. Boston Meridian focuses exclusively on cybersecurity and the adjacent subsectors of governance, risk, and privacy — a deliberate niche. The firm has closed more than $6 billion in transaction value since inception, with the team's cumulative experience exceeding $60 billion in M&A and $18 billion in equity and debt financings. Named deals include advising Industrial Defender on its growth investment from Banneker Partners, Lucidum on its acquisition by Cyderes, SPLX on its sale to Zscaler, SnapAttack on its acquisition by Cisco, and Longbow on its acquisition by Veracode. The firm operates across North America, with offices in Burlington (MA), San Francisco, Reston (VA), and additional locations. The team numbers at least seven principals — John Siracuse, C. Garrett Palm, Matthew Hicks, Shawn Anderson, Anuj Ralhan, Michael Sullivan, and senior advisor Owen L. Hart — but the firm does not publish total headcount. Boston Meridian maintains strategic alliances with OODA, a global security risk advisory, and Hitch Partners, a retained search firm for information security leadership. October 2024: Advised Verve on its acquisition by Rockwell Automation (per the firm). The firm's mandate as an advisory and capital-raising intermediary rather than an asset owner means it is structurally distinct from a traditional family office. Boston Meridian's operating model is fee-based transaction advisory, not direct investment. Its narrow cybersecurity focus and senior-partner-led execution model — where all partners commit fully to each engagement — creates a structural differentiator in the fragmented technology M&A advisory market.

Frequently asked questions
Who runs investment decisions at Boston Meridian Partners?
Boston Meridian Partners is run by co-founders John Siracuse and C. Garrett Palm, who oversee all engagements. Managing directors Matthew Hicks, Shawn Anderson, and Anuj Ralhan, along with director Michael Sullivan, execute transactions. The firm operates with a partner-led model where each engagement receives senior attention from all partners (per the firm's website).
How does Boston Meridian source proprietary deal flow?
Boston Meridian concentrates exclusively on cybersecurity and governance, risk, and privacy companies. Its team includes former technology founders and operators who maintain deep relationships in the sector. The firm also partners with OODA, a global security risk advisory, and Hitch Partners, an information security executive search firm, to generate opportunities.
Is Boston Meridian structured as a single family office or does it operate more like an advisory firm?
Boston Meridian is not a family office. It is an independent M&A advisory and investment banking firm that provides sell-side advisory, growth capital raises, and recapitalization services to growth-stage technology companies. It does not invest proprietary capital on behalf of a family or institution.
What investment stages does Boston Meridian typically target?
Boston Meridian focuses on growth-stage private companies and small-cap public companies in the cybersecurity sector. It advises on M&A transactions (sell-side), growth equity raises, recapitalizations, and strategic advisory engagements.
Which sectors does Boston Meridian explicitly avoid?
The firm deliberately restricts its practice to cybersecurity and closely related areas — governance, risk, and privacy. It does not pursue engagements in other technology verticals such as fintech, digital health, or enterprise software outside that security perimeter.
Does Boston Meridian maintain philanthropic structures, and how are they separated?
The firm does not disclose any philanthropic foundations or charitable vehicles. As an advisory business, any personal philanthropy by principals is separate from the firm's operations.
What is Boston Meridian's known posture on co-investments alongside external GPs?
Boston Meridian is an advisor, not an investor. It does not co-invest alongside GPs as a limited partner. Its role is to represent sellers or raise capital for clients, not to deploy its own balance sheet.
