This Week in Venture: Fintech Breakouts, AI Security Drivers, and Strategic Moves Shaping the Next Wave

Key deals of the week (November 24 - November 28 2025)

Revolut Sets a New Benchmark: A $75B Secondary Signals Its Move Into Institutional Territory

Revolut just rewrote the scoreboard again. A secondary sale now values the company at $75B, pushing it past legacy giants like Barclays and Deutsche Bank and signaling that Europe’s defining fintech isn’t slowing down. In a market recalibrating around profitability and discipline, seeing Coatue, Greenoaks, Dragoneer, Fidelity, a16z, Franklin Templeton, and even Nvidia’s venture arm lean in at this scale says something simple: Revolut is no longer being priced as a fintech upstart but as a global financial institution in the making.

With fresh momentum behind its push for EU and UK banking licenses, plus expanding product rails far beyond payments, the company is positioning itself for a decade where digital-first banking becomes the default.

AI Offense Becomes the New Perimeter: Tenzai Raises $75M Seed Out of Stealth

Tenzai stepped out of stealth with the kind of seed round that instantly recalibrates expectations. The Tel Aviv–based team raised $75M on day one, backed by Greylock, Battery, Lux, and a tight roster of operators who know what real cyber capability looks like. The pitch is unavoidable: fully autonomous AI agents that behave like elite offensive hackers, continuously probing, exploiting, and hardening enterprise systems long before attackers ever show up. It’s a shift from passive defense to perpetual offense, and the size of the seed round reflects how urgently the market wants that transition.

Tenzai is positioning itself at the frontier of AI-native security — where the only way to protect enterprise software is to break it first.

Google and Accel Set the Pace: India’s Early-Stage AI Landscape Levels Up

Google and Accel formalized one of the most strategic early-stage AI partnerships India has seen so far. The two will co-invest up to $2M in at least 10 young AI companies. Google’s first dedicated funding collaboration of this kind at a moment when every major U.S. tech player is racing to plant deeper roots in the world’s largest internet market. With Google already committing $15B to build a massive AI data center in Andhra Pradesh and its AI Futures Fund having backed 30+ startups, this move is less a regional experiment and more a long-term position: India’s founders are increasingly shaping the global AI frontier. Accel and Google are targeting broad creative and technical categories: entertainment, work, coding.

The underlying thesis is simple: early-stage Indian AI companies are about to become meaningfully global, and both firms want to be in the room before that happens.

Clover Security: Embedding AI Into Developers’ Tools to Build Flawless Software From Day One

Clover Security just came out of stealth with $36 million to make secure software the default from day one. The Tel Aviv-based startup, backed by Notable Capital, Team8, SVCI, Wiz co-founders, Shlomo Kramer, ex-CISO Rene Bonvanie, and leaders from Snyk, CrowdStrike, Palo Alto Networks, Atlassian, and Google, embeds AI “security agents” directly into developer tools like GitHub, Confluence, and Slack. These agents think like expert security engineers, spotting design flaws and vulnerabilities early and giving developers real-time guidance.

The new funding will help Clover scale its platform and go-to-market efforts, bringing AI-driven security to fintech, tech, and enterprise teams worldwide.

Climate Infrastructure Moves Center Stage: Overstory Secures $43M Series B for Grid-Resilience Intelligence

Overstory just locked in a $43M Series B to push its wildfire-prevention tech from promising to indispensable. The Amsterdam team has spent years building AI models that turn satellite imagery into real-time vegetation risk intelligence for utilities, and the market is finally catching up to the urgency. Blume Equity led the round, with Energy Impact Partners and long-time supporters doubling down: a signal that grid resilience is shifting from a regulatory checkbox to a core operational priority. With the new funding, CEO Fiona Spruill’s team is scaling its risk modeling engine, expanding partnerships with major U.S. and European utilities, and moving toward a world where power lines don’t spark climate-driven disasters.

Seven years in, 80 people deep, Overstory is positioning itself as one of the few climate-tech companies building infrastructure that utilities can’t ignore.

This week’s activity makes one thing clear: capital is concentrating around companies building foundational infrastructure, whether in finance, cybersecurity, climate resilience, or AI ecosystems. Investors are backing teams that reshape core systems, not surface layers. As these categories mature, the winners will be the ones already establishing themselves as default choices in markets that are shifting faster than ever.
