## Summary

AI platform automating R&D tax credit documentation and filing for 500+ businesses; $12M Series A from Vertex Ventures and ADP Ventures with YC W23 backing targeting under-claimed $20B annual credit market.

## Company Overview

SPRX is an Austin, Texas-based AI-powered R&D tax credit platform that automates the documentation, calculation, and filing of federal and state research and development tax credits for businesses — replacing the manual, spreadsheet-heavy process that CPAs and tax advisors use with an AI system that analyzes employee time data, project records, and qualifying expenses to identify and document eligible R&D activities. Founded in 2023 and a Y Combinator Winter 2023 graduate, SPRX raised $12 million in a Series A in October 2024 led by Vertex Ventures US with participation from Restive Rebels and ADP Ventures, serving 500+ companies with 25 employees.

SPRX's AI platform ingests payroll data, time-tracking records, project management data, and expense reports to identify employees whose activities qualify for the R&D credit under IRC Section 41 — which covers wages paid for qualified research activities, supply costs, and contractor payments. The AI classifies activities against the IRS four-part test (discovering technological information, eliminating uncertainty, process of experimentation, and qualified purpose) and generates the contemporaneous documentation that the IRS requires for credit substantiation during audit.

In 2025, SPRX competes in the R&D tax credit software and advisory market with Clarus R+D (R&D tax credit automation), ADP (through its R&D tax credit services, reflected by ADP Ventures' investment), Leyton, and traditional accounting firm R&D credit practices for R&D tax credit maximization and documentation. The R&D tax credit market is significant — approximately $20 billion in R&D credits are claimed annually by US businesses, and the credit is often under-claimed by startups and SMEs who qualify but don't know or lack the documentation process. IRS scrutiny of R&D credits has increased, making proper documentation more important and creating compliance value for SPRX's defensible documentation approach. Vertex Ventures' Series A lead validates the market size and AI automation potential. The 2025 strategy focuses on growing the SMB and startup customer base, deepening the integration with payroll systems (ADP, Gusto, Rippling) for automated data ingestion, and building the audit defense features that protect customers if the IRS challenges their credit claims.
