- Flourish Health
Participated · Series A · Jul 2026
Flourish Health delivers intensive in-home mental health care for children and young adults through psychiatrist-led Care Pods composed of a child and adolescent psychiatrist, a licensed therapist, a patient guide, and a family guide. The company built a proprietary technology platform that integrates patient touchpoints, EMR and prescribing capabilities, workflow automation, team collaboration, and AI to support engagement and coordination while clinicians make clinical decisions. Flourish specializes in three clinical populations: children with externalizing behaviors, young people with multiple suicide attempts or suicide-related hospitalizations, and patients with complex needs and family situations often turned away by other clinics. Studies run with multiple major health plans report large reductions in hospitalization (70–96%), residential treatment (69–90%), and sustained decreases in higher levels of care post-discharge (80–95%). Flourish commits to beginning care within one week of referral, reports 92% month-over-month retention during its 12-month programs, and says those programs cost less than one month of inpatient treatment.

- Maestro Tech
Participated · Seed · Feb 2026
Very little public information is available about Maestro Tech, Inc. beyond its recent financing activity. The company announced a $1.2 million pre-seed round, indicating that it is still in the product-development or market-validation phase. Investors in the round include New Stack Ventures, Family VC, ZFO, Roark's Drift, and several unnamed angel investors. No specifics regarding the company’s core product, target market, revenue, user base, or future roadmap were disclosed in the source material. The fresh capital will likely be used to fund initial product development, early hiring, and go-to-market experimentation, but the company has not publicly confirmed any such plans. Key operating metrics, geographic headquarters, and founding date were not provided. Consequently, the company’s current financial situation beyond the new capital infusion remains undisclosed.
