About Us



CitareTx Investment Partners was founded in August of 2008 by Jeffery Sheldon and E.J. “Jere” Pederson, both serving as General Partners and Managing Directors of the fund. The company is strategically located in Houston, Texas equidistant from downtown Houston and Galveston island and close in proximity to the Texas Medical Center, the world’s largest of its kind, and the NASA Johnson Space Center.


Our investment activities are primarily focused on Class II medical devices for which the United States Food and Drug Administration pre-market notification process (i.e. 510(k)) can be utilized as the means to obtain regulatory clearance and begin commercial sale of product. However, we remain opportunistic and consider other investments if certain criteria are present, such as the presence of a strategic partner with a defined exit milestones.

Although our team has extensive expertise in the cardiovascular, interventional cardiology, interventional radiology, cardiac surgery, vascular surgery, critical care, consumable product, patient care, and orthopedic markets, we are open to any and all target markets. In addition, we do consider investment opportunities with smaller than typically accepted venture capital market size thresholds.


We are driven by the opportunity to change clinical outcomes and improve patient lives.

Following identification and preliminary evaluation of opportunities we meet with select inventor(s), entrepreneur, and/or management teams, as the case may be, for a formal presentation. In the event that the partners elect to advance discussions further, a detailed due diligence process ensues. During the process, preliminary terms and conditions are discussed to avoid confusion and ascertain strategic fit. Following the due diligence process an investment thesis is prepared, the partnership considers its options, and a term sheet is provided or company is created/direct investment made.

Although we prefer to create a start-up company around a nascent technology, investment into an existing entity is often considered. In any event, we take an active role in the management of our portfolio companies following cash or equity for services investments, including Board representation and participation as Executive Management.

Generally, our companies are collocated with the fund so that shared incubation resources and team members from other portfolio companies can be efficiently and effectively leveraged during product design, development, testing, manufacture, and sale. We believe that the use of shared resources enhances the product development process and reduces time to market.

Our investment and incubation services include:

  • Forming/Incorporating New Entities

  • Obtaining Intellectual Property Rights

  • Investing Seed Capital ($0.5 million - $2.0 million, usually in tranches)

  • Providing Strategic Management & Direction:

    - Established Product Development Plans
    - Conduct Pre-Clinical Testing
    - Interact with Regulatory Agencies
    - Complete Verification & Validation Activities

  • Creating & Managing Scientific and Business Advisory Boards

  • Preparing Business, Financial & Investment Plans

  • Building Management Teams

  • Infusing Follow-On Capital (< $5.0 million)

  • Securing Institutional Growth Capital or Exit
    Our team has strong operating backgrounds and understands the challenges that exists for any start-up company. Partnering is the key to success and we feel that we are a truly value added investment partner.
