RegTech investments are experiencing a meaningful recovery in 2025, with funding climbing 17% year-over-year and deal volume rising 29% as venture capitalists increasingly back AI-powered compliance solutions. After a brutal pullback between 2021 and 2024, the regulatory technology sector is attracting renewed investor attention, particularly at the smaller deal end of the market where confidence is returning fastest .

What's Driving RegTech's Funding Recovery?

The numbers tell a striking story of sector rebound. In 2024, US RegTech closed with 228 deals totaling $5 billion, representing a 64% decline in funding and 58% drop in deal volume from 2021's peak of 537 deals and $14.1 billion raised. However, 2025 brought a decisive shift, with 294 deals generating $5.9 billion in total funding . While the sector remains well below its 2021 highs, the trajectory suggests institutional confidence is gradually returning to an industry that had fallen out of favor.

The most revealing trend is where investors are placing their bets. Deals under $100 million surged 61% in funding value, rising from $2.1 billion in 2024 to $3.4 billion in 2025. This represents a dramatic reversal from the 62% decline those smaller deals experienced between 2021 and 2024. Meanwhile, larger transactions of $100 million or more continued to decline, falling 15% to $2.5 billion in 2025 . The pattern suggests that while smaller investors are regaining appetite for RegTech, institutional capital has not yet returned in meaningful volume.

How Is AI Reshaping Compliance Technology?

The catalyst for this recovery is clear: artificial intelligence is fundamentally transforming how companies manage regulatory risk. Vanta, a RegTech leader specializing in AI-powered trust management, exemplifies this shift. The company just closed one of the biggest RegTech deals of 2025, a $150 million Series D funding round at a $4.15 billion valuation . The round was led by Wellington Management and included backing from Sequoia, Goldman Sachs Alternatives, J.P. Morgan, and Atlassian Ventures, signaling that top-tier venture firms see genuine opportunity in this space.

Founded in 2018, Vanta has evolved from a point solution for automating SOC 2 compliance checks into a comprehensive platform serving over 12,000 companies across 58 countries. The company's AI innovations are delivering tangible efficiency gains that resonate with enterprise buyers. Vanta's AI Agent and Questionnaire Automation features streamline evidence collection and accelerate security reviews, cutting response times by over half and saving teams up to 12 hours per week . These aren't theoretical benefits; they translate directly into reduced operational burden for compliance teams drowning in manual work.

The platform's technology stack reflects how modern RegTech is evolving. Vanta integrates zero-touch verification, vendor risk management, access reviews, and real-time Trust Centers, moving security from static, point-in-time checks to continuous, automated assurance. This shift from periodic compliance audits to real-time monitoring represents a fundamental change in how organizations approach governance, risk, and compliance (GRC) .

Steps to Understand RegTech's AI-Powered Evolution

• Continuous Monitoring: Modern RegTech platforms like Vanta shift from annual or quarterly compliance checks to real-time, automated monitoring that continuously tracks risk and compliance status across an organization.
• AI-Driven Automation: Machine learning models now handle evidence collection, questionnaire responses, and compliance documentation, reducing manual work and cutting response times by more than 50% for security reviews.
• Third-Party Risk Management: AI-powered tools now extend beyond internal compliance to monitor and assess the security posture of vendors and external partners, addressing a critical blind spot in enterprise risk management.

Vanta's funding trajectory underscores investor confidence in this AI-driven approach. The company has raised $504 million since 2021, and the new $150 million Series D will fuel expansion into areas like third-party risk management and government compliance . These are high-stakes domains where automation and AI can deliver outsized value by reducing both risk and operational friction.

Why Are Investors Prioritizing Smaller Deals Right Now?

The shift toward smaller deals reflects a broader recalibration in venture capital strategy. After the frothy 2021 market, when mega-rounds were common, investors are now being more selective about which RegTech companies warrant nine-figure commitments. The 61% surge in deals under $100 million suggests that VCs are building conviction through a broader portfolio of bets rather than concentrating capital in a few large rounds .

This approach makes sense given RegTech's market dynamics. Compliance is a mission-critical function for enterprises, but it's also highly fragmented. Different industries face different regulatory requirements, and different company sizes have different compliance needs. A diversified portfolio of smaller bets allows investors to capture multiple vertical and horizontal opportunities without betting the farm on any single platform becoming the dominant player.

The recovery in RegTech funding also reflects broader economic conditions. As interest rates have stabilized and enterprise software spending has normalized, companies are once again investing in compliance infrastructure. Regulatory requirements continue to multiply, particularly around data privacy, AI governance, and financial crime prevention, creating sustained demand for RegTech solutions .

For founders and investors watching this space, the message is clear: RegTech's AI-powered renaissance is real, but it's unfolding differently than the 2021 boom. Sequoia's backing of Vanta and the broader surge in smaller deals suggest that the next generation of RegTech winners will be built on AI-driven automation, continuous monitoring, and vertical specialization rather than horizontal platforms trying to be everything to everyone.
