It’s May 21, 2025, and we’re back with your daily funding rundown—where the money’s going, who’s writing the checks, and which startups are making moves.
From fintech and AI to sustainability and biotech, today’s batch covers a lot of ground. Some raised big, some stayed quiet on details, but all eyes are on what comes next.
Funding Highlights
Today, several tech startups secured funding, reflecting robust investor confidence. Notable rounds include Airwallex raising $300 million for global payments, SparkCharge getting $30.5 million for EV charging, and Zoca securing $6 million for AI-driven local business solutions. Other highlights include Converge’s €19.4 million for decarbonizing concrete with AI, Mythik’s $15 million seed round for gaming, and DataHub’s $35 million Series B for AI reliability.
Investor Activity
Big names like Square Peg, Bessemer Venture Partners, and Accel are placing their bets across a wide range of startups. Some, like Mythik, are keeping their backers under wraps for now. The mix of sectors suggests investors are staying open-minded, but in a few cases, missing numbers hint at deals still in progress or companies choosing to keep details close.
These rounds reflect an active startup scene, with money flowing into everything from payments and AI to clean tech. Still, tracking the full picture isn’t always easy, especially with stealthier players or early-stage rounds that stay under the radar.
