What haysmacintyre does
HaysMac LLP is a London-headquartered, partner-owned chartered accountancy firm operating as a UK Limited Liability Partnership. Founded in 2001 and staffed by 501-1,000 employees, it delivers a full mid-tier professional services portfolio including audit, tax advisory (with sub-services spanning business tax, employer solutions, employment tax, inheritance tax, private client tax, R&D tax relief, share schemes, strategic tax support, tax disputes, and VAT), outsourcing, risk assurance and advisory, transaction services, company secretarial, and corporate finance (operated under the Green Square sub-brand). Its core technology stack is conventional accounting and business management software; no proprietary platforms, APIs, or AI capabilities were disclosed.
The firm is organised both by service line and by sector specialism, with twelve named verticals: Charities, Education, Financial Services, FinTech, Hospitality, Life Sciences, Media/Marketing/Advertising, Professional Institutes & Membership Bodies, Property, Retail & eCommerce, Sports & Leisure, and Technology. It also addresses five markets — Entrepreneurs and Private Businesses, Equity Capital Markets, International, Private Equity, and Private Wealth. Sector-specialist partner coverage (e.g., Head of Hospitality, Head of Property, Head of Social Purpose, Head of Sport, Co-Heads of Financial Services, Co-Head of Transaction Services) is positioned as the firm's primary differentiator versus generalist mid-tier peers.
Revenue is generated through professional services fees across audit, tax, advisory, transaction, outsourcing, and corporate finance engagements, with pricing structured per engagement (multi-year contract cadence typical of professional services). Go-to-market is sales-led and partner-driven, relying on referrals, sector reputation, and direct business development; demand generation is supported by content marketing (publications and insights), LinkedIn and Instagram presence, email newsletters, and events. No parent company, external investors, acquisitions, or funding events are evidenced; ownership and governance rest with the partnership under Managing Partner Natasha Frangos.
