5 Startup Funding Deals You Probably Missed in February
3 min read
February turned out to be a record-breaking month for venture capital funding. However, most of the headlines were dominated by massive investments in companies like OpenAI, Anthropic, and Waymo. While those big names attracted the majority of capital, several smaller — but fascinating — startups also quietly secured funding.
From robots that can draw blood to AI agents getting their own email inboxes, here are five interesting startup deals from February that may have flown under the radar.
A $70M Bet on Robots That Draw Blood
Healthcare startup Vitestro just raised $70 million in Series B funding to advance its robotic blood-drawing technology.
Founded in 2017, the Netherlands-based company has now raised more than $104 million in total funding, according to Crunchbase. The new round included investors such as Sutter Health, Sonder Capital, Mayo Clinic, Puma Venture Capital, and LabCorp Venture Fund.
Vitestro is developing an Autonomous Robotic Phlebotomy Device designed to perform blood draws automatically. Using imaging technology, artificial intelligence, and robotics, the system can locate veins, guide needle placement, and collect samples.
Blood tests are among the most common medical procedures worldwide, yet the process hasn’t seen much technological innovation. At the same time, hospitals are facing staff shortages in phlebotomy departments. Investors believe automation could help fill that gap while improving accuracy and efficiency.
$50M for a New Approach to Precision Manufacturing
London-based startup Isembard raised $50 million in Series A funding to rethink how factories operate.
The round was led by Union Square Ventures, with participation from Tamarack Global, Notion Capital, IQ Capital, and CIV.
Isembard builds technology for producing precision components used in defense, aerospace, energy, and robotics. What makes the company unique is its franchise-style model. Instead of owning every factory, it allows independent machine shops and new businesses to use its proprietary software and AI-powered system.
The company plans to open 25 factories by the end of 2026 and expand into Germany, France, and Ukraine.
The opportunity is significant: component manufacturing is estimated to be a $1.8 trillion industry, yet about 95% of production comes from small businesses. Many of these shop owners are nearing retirement, creating a potential gap in the industry that companies like Isembard hope to fill.
$13M for Seaweed-Based Wellness Drinks
Food innovation startup Aqua Theon secured $13 million in seed funding to expand its seaweed-based health drinks.
The Torrance, California–based company was founded in 2019 by Alissa Miky. Its first product, OoMee, is marketed as a beverage that supports gut health and satiety.
The drink’s key ingredient is agar-agar, a seaweed-derived compound that has recently gained attention on social media.
The funding round was led by Sparx Asset Management, with participation from Beyond Next Ventures and WiL (World Innovation Lab).
Despite a slowdown in funding for food startups since the pandemic boom, the health beverage market is expected to surpass $192 billion this year, keeping investor interest alive.
$6M to Build Email for AI Agents
Artificial intelligence agents are becoming more common in businesses — and now they might get their own email accounts.
San Francisco startup AgentMail raised $6 million in seed funding to create email infrastructure specifically designed for AI-powered software agents.
According to investors including General Catalyst, AI agents are increasingly acting like virtual employees across industries. However, traditional identity and communication systems were designed for humans.
AgentMail aims to solve that by creating tools that allow AI agents to automatically generate and manage email addresses without human involvement. The company is launching an onboarding API to make that possible.
$1.3M for AI in Wastewater Management
Finally, AI startup Nyad raised $1.3 million in pre-seed funding to help modernize wastewater treatment operations.
The round was led by Boost VC and included investors such as Draper Associates, Halogen Ventures, Ollin Ventures, Apprenti, and First Avenue Ventures.
Founded in 2024 by entrepreneurs Virginia Szepietowski and Christopher Braithwaite, Nyad develops AI software that helps wastewater plant operators monitor systems, maintain compliance, and respond quickly to issues.
The timing could be crucial. Nearly half of the wastewater workforce in the U.S. is expected to retire within the next decade, creating a potential labor shortage. Nyad hopes its technology will help plants operate more efficiently while maintaining public health and environmental safety.
Even though mega-funding rounds often dominate the headlines, these smaller deals show that innovation is happening across a wide range of industries — from healthcare robotics to manufacturing, beverages, AI infrastructure, and environmental technology.
If February is any indication, 2026 could bring plenty of unexpected startup breakthroughs.
