Reunion

What Reunion does

Reunion (doing business as Reunion Infrastructure) is a private marketplace platform for transferable U.S. clean energy tax credits, founded in 2022 by Andy Moon and Billy Lee in San Francisco in response to the Inflation Reduction Act's introduction of credit transferability. The company connects clean energy developers and manufacturers (sellers) with corporate taxpayers (buyers) — primarily Fortune 1000 firms seeking to offset federal income tax liability — and has facilitated more than $7 billion in tax credit face value across 100+ closed transactions since 2024.

The core product, the Reunion Marketplace, orchestrates the full transaction lifecycle: deal pipeline management, buyer curation, due diligence, IRS pre-filing registration, transfer election statement preparation, and closing mechanics. Complementing the marketplace, the PWA Compliance Platform ingests certified payroll data, automatically matches workers to prevailing wage and apprenticeship classifications, and produces audit-ready reports verified by Reunion's audit team, supporting PWA, FEOC, and Beginning of Construction compliance. Supporting products include the Reunion Market Monitor (pricing and demand intelligence) and the Tax Credit Purchase Database (analysis of 1,400+ publicly traded companies and 6,000+ SEC filings), as well as a Transferable Tax Credit Handbook and Compliance Guidebook used as top-of-funnel content assets.

Reunion generates revenue through transaction fees on each facilitated tax credit transfer; pricing is not publicly disclosed and deals are quoted on a per-transaction basis. The go-to-market is sales-led and consultative, with a dedicated transactions team engaging corporate tax departments, CFOs, and treasury functions, as well as clean energy developers and manufacturers. The company is SOC 2 Type 2 certified and operates with a small team (1–10 employees disclosed) that has nonetheless handled transaction sizes ranging from $10M to over $1B, with a reported 45-day average close from term sheet to close and a greater than 95% deal close rate on signed term sheets.
