Third Security typically participates in funding rounds but does not always lead them. Their involvement often depends on the specific needs of the portfolio company.
The firm is open to follow-on investments, particularly if the company demonstrates significant growth and potential for further development in the biotech sector.
Third Security liquidated its remaining venture capital funds in December 2020, so it currently operates without a formal fund structure.
