What Marriott Harrison does

Marriott Harrison is a private UK law firm, structured as an LLP and headquartered at 80 Cheapside in the City of London, that delivers transactional and advisory legal services. Founded in 1985 with a headcount in the 51-100 range, the firm positions itself around serving growth capital investors, high-growth technology companies, and established business leaders navigating challenges related to growing, scaling, financing, refinancing, and buying and selling companies.

The firm's offering is organized into four practice divisions rather than software products: Advisory (commercial contracts, company secretarial, data and privacy, employment, intellectual property, international expansion, real estate, sanctions and export controls, share schemes, and tax), Transactions (equity capital markets, mergers and acquisitions, private equity, and venture capital and emerging companies), Disputes (arbitration, commercial litigation, contentious insolvency, M&A disputes, real estate disputes, shareholder disputes, and technology disputes), and Finance (acquisition finance, corporate lending, leveraged finance, real estate finance, restructuring and insolvency, and venture debt).

As a professional services firm, Marriott Harrison generates revenue through fee-based legal engagements that are not publicly disclosed and are typically quote-based. Its go-to-market rests on direct client engagement via its London office, reputation and expertise positioning, and referral within the venture capital and technology ecosystem, supported by LinkedIn, website content (news, articles, events), and an email newsletter. The firm emphasizes themes of technology, responsibility, and sustainability, and cites work including legal advice on ZERØTEC's £642,000 pre-seed round led by Bethnal Green Ventures and Apoha's Series A backed by Singular and Redalpine.
