- UnityAI
Led · Series A · Mar 2026
Founded in 2023 by former HCA Healthcare executives, Nashville-based UnityAI develops artificial-intelligence scheduling agents that streamline operations for outpatient and specialty care providers. Its platform keeps clinical workflows moving in high-volume, rapidly changing environments, reducing administrative bottlenecks for customers such as Tennessee Oncology and Peregrine Health. The company reports that its solution is already deployed at nationwide scale, demonstrating reliable performance in real-world clinical settings. Proceeds from the latest round will be used to deepen product capabilities and expand go-to-market efforts, especially with multi-site provider platforms. UnityAI aims to move health systems beyond isolated point solutions toward integrated, AI-powered operations. Including the new capital, the startup has raised a total of $15 million to date, underscoring growing investor confidence in its approach.
- Croissant
Led · Equity · Feb 2026
Croissant operates a consumer-commerce marketplace that offers shoppers 10% cash back on purchases at partner brands and locks in future resale prices, encouraging higher-quality, long-term buying decisions. The company pairs this shopper incentive with a financing mechanism that predicts future spend and pre-funds it for merchants, effectively supplying brands with fee-free, non-dilutive working capital. Croissant’s network already includes retailers such as Nordstrom, Revolve, Reformation and SSENSE. To date, the platform has generated more than $50 million in gross merchandise volume from over 100,000 users. Management plans to use new capital to acquire additional shoppers and expand its roster of retail partners, further fueling its demand-pre-funding engine. Including the latest raise, Croissant has secured $52 million in total funding to build out its data-driven infrastructure for commerce. The company maintains a presence in New York and Nashville.
- Verisoul
Participated · Series A · Dec 2025
Austin-based Verisoul delivers an all-in-one fraud detection platform that combines real-time behavioral, device, network, and identity forensics to determine whether each user is “Real,” “Suspicious,” or “Fake.” Its spoof-resistant approach, scored by internally developed AI models and customer-specific rules, enables the company to win more than 80% of head-to-head technical evaluations against incumbent solutions. In just two years of commercialization the startup has grown from zero to 100+ customers, registering 6× year-over-year ARR growth and protecting clients such as Clay, Augment Code, and Morning Consult from hundreds of millions of AI-driven attacks. The product serves 12 industries, spanning advertising, market research, payments, and financial services. Verisoul was named Austin’s 2024 “Emerging Startup of the Year.” The company was founded by veterans of TransUnion, Meta, and Capital One and positions itself as the single source of truth for user integrity in high-growth businesses.
- Bone AI
Led · Seed · Nov 2025
Bone AI is a Seoul- and Palo Alto-based startup building a unified "physical AI" platform that integrates advanced autonomy software, embedded engineering, hardware design, and large-scale manufacturing. The company’s initial focus is on defense-oriented unmanned aerial vehicles that can handle logistics support, wildfire detection, and anti-drone defense, with plans to extend the same autonomy stack to ground and marine robots. To accelerate go-to-market, Bone AI acquired South Korean drone maker D-Makers and its IP just six months after launch, giving the young venture mature products and immediate revenue. The strategy pairs in-house AI expertise with South Korea’s deep manufacturing base to create an integrated supply chain for smart robotics, which the team hopes to expand to the U.S., Europe, and other allied markets. Bone AI is already commercial, having secured a seven-figure B2G contract and generating $3 million in revenue in its first year. It has also been selected for a government-backed end-to-end logistics program deploying its UAVs and UGVs. Founder DK Lee views the company as filling the gap between Asia’s strong hardware sector and its nascent defense-tech startup scene, aiming to mirror success stories like Anduril and Helsing in other regions.
- Everstar
Led · Equity · Nov 2025
Everstar is a U.S.–based startup behind Gordian, an artificial-intelligence platform that automates regulatory compliance and licensing processes for nuclear plants and other critical industrial operations. Gordian combines AI with deep sector expertise to prepare technical documentation, streamline licensing workflows, and reduce compliance costs while strengthening collaboration between companies and regulators. Its capabilities cover both existing plants and new reactor projects, including small modular reactors (SMRs). The platform has already cut Last Energy’s expected eight-week environmental assessment to just one week, demonstrating meaningful time savings. Everstar sees growing demand for its solution as AI proliferation and data-center expansion drive global energy needs and heighten interest in low-carbon, always-on nuclear power. The company recently secured $5.5 million in new funding, adding to a pre-seed round completed in early 2025.
