- Queen One
Participated · Equity · Aug 2026
Founded in 2022 by CEO Ryan Urban, COO Maricor Resente and Head of Marketing Megan Kresinske, Queen One builds AI-driven software that analyzes shopper behavior to personalize timing, frequency and content of marketing across channels. The platform targets consumer brands—primarily apparel, retail, beauty and home—and the company says it can serve any brand with more than $500,000 in commerce. Queen One reports that its technology has doubled email-generated revenue for some early customers, though it did not disclose customer names or overall revenue. The company employs just under 100 people and has assembled commerce executives and technologists, including veterans from Wunderkind; it raised $5.5 million in early 2025 and has roughly $37.5 million in committed capital, financing and incentives. Queen One has pledged major expansion in Brooklyn—a 30,000-square-foot headquarters backed by up to $6 million in state tax credits and commitments to create 600 jobs by 2030—and says it plans to go public in 2028 under the ticker HEXY.
- BRANDRANK.AI
Participated · Seed · Jul 2026
BrandRank.AI provides an Answer Engine Optimization (AEO) SaaS platform focused on measuring brand visibility, vulnerability, and content readiness in AI-generated answers.

Its roadmap includes capabilities for accuracy verification, anti-hallucination monitoring, brand risk alerts, a Brand Health Index, and enterprise trust analytics geared toward agentic AI systems. In just over two years the company has worked with nearly 100 brands and organizations, joined the NVIDIA Inception Program, and was named Nestlé Canada's 2026 Startup of the Year; it was also named a Representative Vendor in Gartner's 2026 Market Guide for Answer Engine Visibility Tools. Key customers cited include Nestlé, Procter & Gamble, Goodwill International, National Public Media, Kroger, Mars, the American Medical Association, and Better Business Bureau chapters. The company intends to use the new seed proceeds to accelerate enterprise growth, expand delivery and vertical solutions, and integrate Averi to move customers from insight to execution across AI answer engines.
- Venus Aerospace
Led · Series B · Jul 2026
Venus Aerospace develops rotating detonation rocket engines (RDRE) and has shifted focus toward hypersonic weapons and high-speed space vehicles after a successful flight demonstration in 2025. The company was founded in 2020 by CEO Sassie Duggleby and CTO Andrew Duggleby. Its propulsion architecture emphasizes efficiency, throttling, reusability, and manufacturability aimed at defense and space customers. Venus has conducted about 600 engine tests with a longest-duration burn of 32 seconds to date, while customers require burns of roughly 6 to 15 minutes for operational missions. This year it received a grant from the Texas Space Commission to build a larger test stand to enable longer-duration testing. The company is using new equity from its $90M Series B to fund vehicle-specific testing and development with potential customers.
- OpenTrade

OpenTrade provides infrastructure that connects stablecoins to diversified yield strategies for fintechs, neobanks, exchanges, treasuries, and asset issuers, allowing clients to offer dollar- and euro-denominated yield products without building their own custody or investment systems.

OpenTrade reports more than $200 million in total value locked and processed over $250 million in transaction volume in 2025, and counts partners such as Littio, Midas Kripto, and Glim. Its roadmap includes scaling its infrastructure, formalizing regulated asset management oversight within Curation+, and growing engineering, asset management, and customer success teams. The company intends to scale globally and support a broader range of retail and institutional use cases as demand for stablecoin yield infrastructure increases with the expanding stablecoin market.
