- MaxQ Medical
Led · Series A · Aug 2026
MaxQ Medical is developing a fully automated, urethra-preserving transurethral ultrasound imaging and targeted therapy platform that combines advanced imaging with tissue-selective therapy in a single outpatient procedure. The system is intended to give urologists full visibility inside the prostate and enable treatment of visualized disease while minimizing urethral injury, swelling, bleeding, and sexual side effects. The company's initial indication is benign prostate hyperplasia (BPH), with planned expansion into focal therapy for prostate cancer and broader prostate diagnostics including biopsy and tumor mapping. MaxQ is the first spinout from Orchard Ultrasound Innovation and is based in Sunnyvale, California. The MaxQ System is investigational and not currently available for commercial use in the United States. The company recently raised $31.5 million in a Series A to grow its team and advance its clinical program.
- Boom
Led · Series A · Aug 2026
Boom provides an AI-native leasing operating system that combines leasing operations, applicant screening, and rent reporting in one platform. The company launched BoomScreen in mid-2024 and has since introduced BoomCRM, an AI-powered leasing and touring CRM designed to manage the entire leasing funnel from lead capture to tour booking, screening and approval. Boom reports supporting 500K+ rental units and more than 500 operators on its platform, and says its tools reduce response times to seconds and decisions to hours. The product embeds modern large language models across workflows to automate and speed leasing tasks. Boom has attracted both institutional venture investors and strategic operator investors and recently closed a $15M Series A led by S3 Ventures. The company states strong customer momentum and adoption following its product launches.
- Versa Vascular
Participated · Series C · Aug 2026
Versa Vascular is developing the AdapTR transcatheter tricuspid repair device and a delivery platform designed to support native leaflet function while enabling repositioning, implant control, and atrial device positioning to simplify intraprocedural imaging. The company reported positive clinical results and is conducting a first-in-human study outside the U.S. and planning a U.S. Early Feasibility Study. Versa intends to use recent financing to complete those clinical programs and to continue product development and optimization. Leadership changed as part of the update: longtime Medtronic structural heart executive Bill Shields was named CEO, succeeding David Hovda, who will remain as an advisor. Shields brings experience leading transcatheter mitral and tricuspid programs and product development and clinical studies.
