Founded in 2020, New York-based Onshore (formerly SPRX) offers an AI-driven platform that combines structured data pipelines, proprietary machine-learning models, and expert review to turn raw payroll, ledger, and project evidence into fully audit-ready tax incentive reports. Its technology enables business-component level analyses that deliver studies up to 90% faster, at 30–50% lower cost, and with roughly 15% more eligible credits than traditional providers. More than 500 companies across technology, energy, manufacturing, architecture, and agriculture have used Onshore to uncover and defend over $600 million in R&D credits, 179D deductions, and cost-segregation benefits. The company positions itself as a replacement for manual, billable-hour tax services, emphasizing precision, transparency, and speed. With $46 million raised to date, Onshore plans to extend its intelligent-automation approach beyond tax credits into broader financial and accounting workflows that support corporate compliance and reporting.
