Arranged from the smallest to the largest raise, these stories reveal how diverse industries—from robotics and fashion to AI healthcare—are redefining the business landscape.
Viam – $30M
Viam is reshaping how industries connect AI, data, and physical devices. Headquartered in New York City and founded by Eliot Horowitz, the former CTO of MongoDB, Viam delivers a platform that allows developers to integrate robotics and IoT automation seamlessly.
With $30 million in fresh capital led by Union Square Ventures, the company plans to accelerate adoption in manufacturing, logistics, hospitality, and even maritime technology.
This round reinforces Viam’s vision of bridging AI capabilities with real-world machines. Recent collaborations include partnerships with Viking Yachts and a pilot with Kongsberg in marine automation, signaling how adaptable their platform can be.
By providing an infrastructure layer for intelligent devices, Viam is making it easier for businesses to deploy automation without starting from scratch.
The funding also marks a step toward international reach. With European investor Neurone joining the round, Viam is eyeing expansion into markets where industrial automation is still untapped. This approach positions them to become a critical connector between AI software and the devices that power everyday life.

Its $40 million Series C, led by Koch Disruptive Technologies, strengthens its ability to serve large-scale carriers and freight brokers.
The platform leverages decades of Princeton research in transportation modeling to help companies decide which loads to take and how best to allocate trucks.
This level of decision automation allows logistics firms to boost profitability while minimizing inefficiencies. Clients like Uber Freight have already embraced the platform to improve fleet management.
With supply chains under constant pressure, Optimal Dynamics’ solution stands out for its combination of speed, adaptability, and long-term planning. The latest funding will allow the company to scale its technology team, refine its AI models, and expand customer success capabilities.

Its $72 million Series C, led by Adams Street Partners, underscores growing investor interest in this emerging “loss tech” sector.
The platform blends human-centric support with tools for funeral arrangements, estate documentation, claim processing, and its LifeVault™—a secure space for storing legal and personal documents.
Partnering with insurance companies, Empathy supports more than 45 million people in North America, handling one in five life insurance claims in the United States.
This latest capital injection will help Empathy deepen its integration with insurers and expand outreach to families navigating complex legal and emotional challenges. In a sector often overlooked by tech, Empathy’s blend of compassion and technology offers a rare balance.

More than 85,000 clinicians across 130 organizations use Nabla’s platform, reporting significant reductions in administrative time. The result is improved patient care and reduced burnout for doctors.
The company is also innovating in inpatient and nursing settings, where its AI can handle coding and other repetitive tasks. With the new funding, Nabla aims to refine its “agentic” capabilities—allowing the assistant to take proactive actions that further streamline workflows.

This technology has drawn the attention of the U.S. military, securing contracts with the Army, Air Force, and unified combatant commands. Hidden Level’s systems are especially relevant in protecting critical infrastructure as drone use rises across industries.
The funding will accelerate the expansion of its detection networks, positioning the company as a leader in safeguarding both civilian and defense airspace from emerging aerial risks.
Vivrelle – $62M
Vivrelle offers a unique twist on the luxury fashion market. Based in New York City, the company runs a subscription service giving members access to high-end handbags, jewelry, and diamonds. Its $62 million Series C, funded entirely by Protagonist, will fuel showroom expansion and technology development.
Founded in 2018, Vivrelle has built a loyal customer base by providing “access over ownership” for luxury goods. A 14,000-square-foot showroom in New York has become a centerpiece for members to browse and borrow items.
The new capital will help Vivrelle expand into new cities and broaden its designer partnerships, continuing its mission to make luxury fashion more accessible.
