What Leyton does

Leyton is an international consulting firm founded circa 1997-1999 that helps businesses identify and claim financial incentives — primarily R&D tax credits, energy efficiency incentives, government grants, and state and local tax recoveries — across roughly 12 countries spanning Europe, North America, and Africa. The firm serves software/technology, manufacturing, life sciences, construction, hospitality, energy technology, and agriculture clients, with documented concentration in small and medium businesses and Canadian innovation companies. Its core products include R&D Tax Credit Services, SR&ED Tax Credits (Canada), Energy Efficiency Incentives (including §45L and §179D), Employee Retention Credit representation, State and Local Tax (SALT), Payroll R&D Tax Credit, Orphan Drug Tax Credit, Cost Segregation, Property Tax Advisory, M&A Advisory, and a portfolio of provincial Canadian credits (CRIC, C3I, OMMITC, CDAE, Multimedia). A digital application branded "Leyton 4 Me" (US) / "Leyton for Me" (Canada) is used to digitize and streamline client applications.

Leyton operates a hybrid delivery model combining technical experts (engineers, PhDs, scientists) with tax specialists who jointly scope, document, and defend claims from initial assessment through audit support. The revenue model is success-based: no upfront payment, no hourly billing, and no charge if no eligible activity is identified; fees cover technical analysis, financial review, documentation, and audit defense without separate charges for complexity. The firm is privately held under the French parent entity THESEE, with wholly-owned Leyton USA and Leyton Canada subsidiaries, and reports over 50,000 businesses served cumulatively, $500M+ in tax relief delivered to clients, and a 96% client satisfaction rate in Canada. Go-to-market is sales-led, augmented by CPA and tax-professional referral partnerships, a NASBA-certified CPE program for accounting professionals, content marketing, webinars, and a refer-a-friend program.
