Formerly SPRX. AI-native platform for automated corporate tax incentives
About Onshore
Onshore is an AI-native tax platform designed to modernize the corporate tax services industry by replacing manual accounting workflows with intelligent automation. The company provides a high-precision system that identifies, optimizes, and defends complex tax incentives, moving away from traditional models that rely on billable hours and manual spreadsheets. Its core mission is to transform tax departments from cost centers into growth capital drivers by unlocking billions of dollars in unclaimed or misfiled incentives.
The platform serves a diverse range of over 500 B2B clients across industries such as technology, energy, manufacturing, and agriculture. Onshore operates as a Software-as-a-Service (SaaS) provider, enabling finance teams and CFOs to manage tax workflows with transparency and continuous intelligence. By connecting directly to payroll, general ledger, and project management systems, the platform automates data ingestion and validates technical evidence against IRS standards in real-time.
Onshore differentiates itself through an AI-first architecture that conducts detailed business-component analysis instead of the statistical sampling common in traditional firms. This approach reduces the time required for R&D tax credit studies from months to just 28 days while identifying an average of 15% more eligible credits. The platform integrates proprietary machine learning models with expert oversight to ensure every claim is fully traceable and audit-ready, providing a scalable solution for corporate compliance and strategic financial planning.
