Defined.ai Reports 65% Revenue Growth as Global Demand for AI Training Data Accelerates
The company achieved a 143% Net Revenue Retention rate in 2025, alongside the 1,200% increase in partner data on its marketplace and key leadership hires, cementing its position as core data infrastructure for Generative AI.
SEATTLE, WASHINGTON / ACCESS Newswire / January 27, 2026 /Defined.ai, a leading provider of ethical, high-quality training data for artificial intelligence, today announced strong financial and operational performance in 2025, driven by rising global demand for compliant, high-quality AI datasets. The company reported 65% year-over-year revenue growth and achieved a Net Revenue Retention (NRR) rate of 143%, reflecting deepening enterprise adoption and expansion across existing customers.
The results highlight a broader shift underway in the AI market. As regulatory scrutiny intensifies and legal risks associated with scraped data grow, enterprises are consolidating their AI data supply chains. "In a market flooded with scraped and legally risky data, 2025 was the year the industry voted with its wallet for compliance and quality, " said Daniela Braga, Founder and CEO of Defined.ai. "We are no longer just a vendor. Defined.ai has become the foundational infrastructure for safe, scalable generative AI. Customers are increasingly relying on us not only for initial data procurement, but as a long-term partner for scalable, ethical model training. "
Operational Discipline and Financial Strength
Defined.ai 's growth has been underpinned by disciplined execution and a strategic shift toward higher-margin, technology-enabled data solutions. "Achieving 143% NRR is a strong signal of our customer satisfaction and growth capacity, " said Daniel Navas, CFO of Defined.ai. "It shows that we are capturing high-quality enterprise demand with meaningful operating leverage, and that we have successfully transitioned from early-stage growth to a scalable, predictable financial model. "
Marketplace Expansion and Data Monetization
As demand for AI training data continues to outpace supply, Defined.ai has emerged as a preferred monetization channel for organizations holding valuable proprietary data assets. In 2025, the Defined.ai Data Marketplace saw a 1,200% increase in third-party partner datasets, driven by the platform 's security, licensing controls, and immediate revenue potential. Several partners now generate more than $1 million annually by licensing proprietary datasets through the marketplace. Demand has been particularly strong for multimodal data, including datasets supporting robotics, computer vision, and specialized healthcare applications.
Leadership Momentum and Regulatory Readiness
To support its next phase of growth, Defined.ai expanded its leadership team in 2025 with senior hires across departments including data annotation and data collection, bringing experience from major data incumbents and global technology companies. As AI regulation accelerates globally, Defined.ai believes its long-standing focus on ethical sourcing and consented datasets has become a key strategic advantage. "With the EU AI Act coming into force and U.S. policy continuing to evolve, our customers view compliance as infrastructure, " Braga said. "Defined.ai provides ethically sourced, compliant data that allows AI teams to innovate without legal risk. "
