Frequently asked questions
What types of capital does WindSail Capital Group provide?
WindSail provides a mix of equity and structured credit. The firm targets venture-stage and growth-stage companies, and it is known for engaging in complex situations where standard venture capital terms are insufficient. This includes structuring non-dilutive or customized capital solutions alongside direct equity investments.
Does WindSail operate as a venture capital fund or a specialty lender?
WindSail blends characteristics of both. Unlike a pure venture capital fund, it does not limit itself to minority equity positions. It acts as a direct counterparty that can underwrite credit and equity within a single transaction, which allows it to serve companies that fall between traditional venture equity and bank-led debt offerings.
