- CBR
Health
Cord Blood Registry (CBR) operates as a private bank for newborn stem cells, focusing on the collection and cryopreservation of both umbilical cord blood and cord tissue for its clients. CBR's business model is centered on a direct-to-consumer approach, serving expecting parents who choose to privately bank their newborn's stem cells for potential future medical use by the child or compatible family members.Revenue is generated through initial processing fees and recurring annual storage fees. For example, cord blood processing, which includes testing and the first year of storage, is priced around $1,675, with an subsequent annual storage fee of $175. The company's core service involves providing families with a collection kit to be used at the time of birth. The collected cord blood, a source of hematopoietic stem cells (HSCs), and cord tissue, a source of mesenchymal stem cells (MSCs), are then transported to CBR's facility in Tucson, Arizona, for processing and long-term storage. These cells can be used in the treatment of over 80 medical conditions, primarily blood and immune system disorders. A significant aspect of CBR's strategy is its investment in the future applications of stored stem cells. The company actively partners with research institutions to facilitate FDA-regulated clinical trials, giving its client families potential access to emerging therapies for conditions like autism, cerebral palsy, and acquired hearing loss. Notably, a high percentage of stem cell units released by CBR have been for use in experimental regenerative medicine applications. CBR also provides resources such as the Family Health Registry to connect client families with relevant clinical trials. Over its history, CBR has undergone several ownership changes, including acquisitions by AMAG Pharmaceuticals in 2015 for $700 million and later by private equity firm GI Partners in 2018, which merged it with California Cryobank. It now operates under the umbrella of Generate Life Sciences, which was subsequently acquired by CooperCompanies.

- ClearPath Receivables
Fintech, Enterprise software
ClearPath Receivables operates as a corporate intelligence firm that develops and manages custom artificial intelligence solutions centered on the order-to-cash (O2C) process. The firm is backed by a network of CFOs and CIOs and led by founder Isiah. Rather than selling standardized software, the company builds bespoke intelligence programs designed to integrate with a client's existing accounting systems, including platforms like NetSuite, QuickBooks, SAP, and Xero. The firm's business model is structured as a managed service, focusing on delivering a complete solution from data preparation through AI deployment and ongoing management. A primary differentiator is the initial phase of data cleansing; ClearPath prepares and reconciles a company’s financial data—addressing issues like unapplied payments and credits—before implementing any AI. This ensures the AI models are built on accurate data, which the company states is critical for generating reliable outcomes. The service is designed to enhance cash flow, lower Days Sales Outstanding (DSO), and reduce operational costs for its clients, which typically include CFOs, controllers, and accounts receivable managers. Key features of the custom AI programs include automated payment matching, intelligent dunning, customer risk scoring, and payment prediction. Beyond operational efficiency, ClearPath transforms raw receivables data into actionable sales and customer intelligence reports, providing insights into customer payment behaviors, churn risk, and revenue patterns. The company positions itself as an alternative to both AI software vendors that don't handle data preparation and traditional accounting firms that don't build AI, offering a managed intelligence solution that provides high-level expertise for the cost of an accounts receivable manager.
