The Next Generation of NYC Startups: H1 2026 Seed Funding Analysis
Every breakout startup starts somewhere.
Long before the headlines, the unicorn valuations, and the IPO buzz, there’s a seed round, AKA the first institutional vote of confidence that an idea — and a founder — is worth betting on.
That’s why, for the first time, we’re taking a look at the NYC startups that raised a seed round during the first half of 2026.
Spoiler alert: New York’s earliest-stage ecosystem is thriving.
In H1 2026 240+ NYC startups, founders raised at least a combined $1.13 billion in seed funding, with the average seed round reaching $6.64 million. Like almost all 2026 venture trends, it marks an increase from H1 2025, when seed stage founders raised a collective $1.06billion with the average round totally $5.4 million.
Together, these companies span nearly every corner of the economy, from AI and healthcare to climate, fintech, robotics, cybersecurity, construction, and consumer technology.
If our Series A: A Series project tracks companies entering their next phase of growth, this is a snapshot of the pipeline that’s feeding it.
Here’s what stood out.
AI is the foundation
If there’s one defining theme across this year’s seed cohort, it’s that AI has become the foundation for nearly every sector of the startup ecosystem.
Companies primarily building AI and enterprise software attracted roughly $500 million, or nearly 45% of all seed funding raised during the first half of the year.
Startups like Reflections.ai, Hypha AI, F2 AI, ActionAI, Obin AI, Passu, and Solid are building the next generation of AI infrastructure, developer tools, and enterprise software.
AI is showing up everywhere, from healthcare and financial services to robotics, cybersecurity, manufacturing, and climate. Increasingly, founders aren’t pitching “AI companies,” but instead they’re building companies that use AI to reinvent entire industries.
Digital health continues its winning streak
Digital health and life sciences remained one of NYC’s largest destinations for seed capital, bringing in approximately $180 million during the first half of the year.
Companies like Proxima, Coefficient Bio, Crosby Health, Ready Health, Claim Health, Understood Care, Kadia Health, and Oasys Health are tackling everything from computational drug discovery and diagnostics to patient access, care coordination, and AI-powered clinical operations.
That mirrors a trend we’ve seen throughout our Series A tracking — that digital health remains one of NYC’s deepest startup strengths.
Fintech keeps evolving
Financial technology accounted for roughly $150 million in seed funding, reinforcing New York’s position as one of the world’s leading fintech hubs.
Today’s founders are focused less on consumer banking and more on infrastructure.
Companies including Checker, Titan, Treasury, Kulipa, Formulary Financial, Exponent Finance, Client Pay Direct, and Neon are modernizing payments, wealth management, accounting, embedded finance, and financial operations.
It’s another reminder that New York’s competitive advantage remains financial services, and increasingly, the software that powers them.
Security, climate, and robotics are growing
Beyond the largest sectors, several emerging categories continued to gain traction.
Cybersecurity startups raised approximately $65 million, led by companies like Crash Override, Charm Security, Symbiotic Security, Tenet Security, BizDefender, and QuickSecure as enterprises race to secure increasingly AI-native systems.
Meanwhile, climate and energy startups attracted roughly $40 million, with companies like Qnetic, Cedar, Patina, and Restoration Climate building technologies for decarbonization and resilience.
Robotics and industrial technology also continued to expand, raising around $45 million through startups like Tangent Robotics, Fauna Robotics, OFFROAD, and Aniai.
The investors backing the next generation
The investors behind these companies tell a story of their own.
Firms like BoxGroup, Y Combinator, Alumni Ventures, Lerer Hippeau, Flybridge, General Catalyst, Soma Capital, Slow Ventures, and Andreessen Horowitz appeared repeatedly across the dataset, continuing to make early bets on NYC founders.
That mix of hometown investors and national firms is one of New York’s biggest strengths. Local seed funds help companies get off the ground, while global venture firms increasingly recognize NYC as one of the world's premier startup ecosystems.
Why it matters
A year into publishing Series A: A Series, we’ve seen firsthand how quickly today’s seed companies become tomorrow’s growth stories.
Many of the startups raising Series A rounds today first appeared on investors’ radar just a few years ago as seed-stage bets.
This new snapshot offers a look even earlier in that journey.
Some of these companies will never raise another round. Others will become the names we’ll be writing about in future editions of Series A: A Series.
Either way, this is where the next generation begins.
