- Prosper Medical
Participated · Seed · Jul 2026
Prosper Medical operates an AI-enabled concierge primary care platform that aggregates patient health data, maintains continuity across interactions, coordinates care, and augments physician workflows with an AI care layer. Founded by Ryan McQuaid and Dr. James Wantuck (the founders of PlushCare), the company aims to deliver a personalized physician relationship at scale. Prosper is available to patients in all 50 states and is in-network with many major insurance plans. In its first months of operation the company has grown to serve thousands of members. Leadership frames the product as augmenting, not replacing, clinicians—combining Prosper AI, a Care Concierge Team, and doctors who arrive with patient context. The company plans to use recent financing to expand its physician network, further develop its AI platform, and accelerate market expansion.
- ReFiBuy
Participated · Seed · May 2026
ReFiBuy develops infrastructure that transforms product catalogs so they can be evaluated, compared, and recommended by AI agents. The company describes its work as creating Agentic Commerce Optimization to bridge the gap between current retailer catalogs and agent-driven purchasing workflows. Its product aims to make product data machine-usable for discovery and purchase decisions on AI platforms. ReFiBuy announced an oversubscribed $13.6M Seed raise, providing its current financial runway. The company presented the funding as a response to most brands and retailers not being ready for agentic commerce and as a way to help them adapt.
- City Detect
Participated · Series A · Mar 2026
Founded in 2021, City Detect equips city-owned vehicles such as garbage trucks and street sweepers with cameras that capture street-level imagery, which its patented computer-vision system analyzes to flag graffiti, illegal dumping, litter, structural roof damage, and other code-related problems. The platform automatically blurs faces and license plates, can distinguish between street art and vandalism, and helps officials prioritize remediation without relying on labor-intensive manual inspections. Operating in at least 17 U.S. cities, including Dallas and Miami, the company claims its AI can review thousands of buildings per week compared with roughly 50 for traditional human inspections. City Detect is SOC 2 Type II compliant, a member of the GovAI Coalition, and has published a Responsible AI policy to guide its work with municipalities. The firm has raised $15 million to date and plans to use new capital to hire additional engineers, enhance its storm-damage detection capabilities, and expand to more U.S. cities. CEO and co-founder Gavin Baum-Blake leads the company’s growth and technology strategy.
- Opine
Participated · Seed · Dec 2025
Opine offers a single, AI-powered platform where presales, sales, and post-sales teams collaborate on complex enterprise deals. The workspace consolidates disparate tools, data sources, and departmental workflows to surface deal risks early, automate repetitive tasks, and maintain a continuous record of customer commitments. In 2025, the company reported 10× year-over-year revenue growth, underscoring rapid market adoption. Customers cite faster answers, clearer opportunity insights, and reduced internal meetings—sometimes eliminating a 30-minute call with one query—after switching to Opine. Opine plans to invest heavily in workflow automation, real-time deal intelligence, and a unified data infrastructure. The new capital will also support an expanded go-to-market push as technical sales becomes increasingly strategic for modern B2B vendors. Founded in Raleigh, the company is trusted by leading B2B technology providers to manage sophisticated sales cycles with precision.
- Qualytics

Qualytics provides an AI-driven, enterprise platform for augmented data quality that automates anomaly detection, intelligent rule generation, and remediation via no-code workflows. The platform integrates with cloud-native and legacy systems and tools including Databricks, Snowflake, SQL Server, Oracle, Atlan, and Alation. Qualytics surfaces more than 30,000 real-world anomalies per month and recently signed a top‑3 U.S. financial institution, demonstrating traction with large data-driven enterprises. The company reported 5x revenue growth over the past year, driven by demand for proactive data quality in AI and analytics initiatives. To support accelerating demand the company is scaling its team across engineering, product management, customer success, and sales. Planned product and go-to-market expansion aims to deepen platform capabilities, speed customer onboarding, and increase support for existing users. Qualytics provides an active, scalable data quality platform for enterprises. Led by CEO Gorkem Sevinc and based in Orlando, FL, it offers a scalable solution across the entire data quality lifecycle. The platform enables subject matter experts and data engineers to collaborate on data quality at scale through advanced automation and intelligent workflows. Qualytics raised $2.5M in funding in a round led by Tech Square Ventures. The company intends to use the funds to scale demand from Fortune 500 enterprises. The funding involved a mix of venture firms, funds and individual backers. Qualytics offers the Qualytics Data Firewall, a platform that monitors data with real-time surveillance. The platform uses advanced data operations and machine learning to enable governance, auditing, and data security by detecting data quality anomalies in real time and preventing bad data from entering downstream systems. The company is focused on a critical gap—data integrity. Qualytics was founded in April 2020 by Gorkem Sevinc and Dan Roche and is based in Baltimore, Md. The company operates as a tenant at the bwtech@UMBC Research & Technology Park. Its current financing activity includes an ongoing seed round with participation from institutional and angel investors.
