What White Mountain Capital does

White Mountain Capital is an independent, privately held registered Broker-Dealer founded in 1999 by Peter Montalbano and headquartered in Greenwich, Connecticut, with an additional office in Bay Harbor Islands, Florida. The firm serves three distinct client segments: retail investors (individual investors at various life stages requiring brokerage and retirement planning services), institutional investors (hedge funds, proprietary trading firms, and asset managers seeking execution services), and middle-market and emerging growth companies seeking capital-raising services through private placements and exempt offerings. The firm operates three service lines — Retail Brokerage, Institutional Trading, and Investment Banking — alongside Summit by White Mountain Capital, a proprietary digital investment marketplace that connects issuers with investors for exempt offerings and Regulation Crowdfunding transactions, with a retail investor minimum investment as low as $250 per offering.

The firm's underlying technology stack centers on the Summit platform, which enables issuers to list offerings, investors to review materials and terms, and transactions to be executed through a secure portal, supported by integrations with SEC-registered transfer agents for cap table management and third-party escrow agents for fund administration. Institutional trading is delivered through smart order routing with multiple settlement options and access to international ETF, options, stock, derivative, and fixed income markets. Retail brokerage operations are powered through a clearing relationship with Hilltop Securities Inc, which handles transaction processing, clearing, custody, customer confirmations, and customer login infrastructure, with disaster recovery and business continuity plans maintained jointly.

The business model is entirely transaction-fee based across all four revenue streams: retail brokerage commissions, institutional trading fees, investment banking fees on capital raises (5% cash or securities commission with a $25,000 minimum, $8,000-$12,000 expense reimbursements, and $1,500 escrow fees per closing), and Summit platform fees (with issuers sometimes paying in securities of the same class offered). Summit does not charge investors. White Mountain Capital is a member of FINRA, SIPC, and MSRB, generating revenue as a small independent broker-dealer (11-50 employees) with no outside institutional ownership, no disclosed funding rounds, and no public revenue figures.

3. Investment Banking Fees: Capital-raising services for emerging and middle-market companies through private placements and exempt offerings, generating commission-based fees tied to amounts raised. Issuers pay cash commissions of 5% of amount raised (minimum $25,000), securities commissions of 5%, expense reimbursements of $8,000-$12,000, and escrow fees of $1,500 per closing.
