Vistara Growth operates as a hybrid venture capital fund that blends growth debt and growth equity into custom capital structures for mid- to later-stage technology companies, targeting businesses that are too mature for traditional venture capital but don't fit standard private credit. The firm has maintained a decade-long track record of zero losses at the fund level across more than 40 investments and 20 exits, using a security, yield, and upside investment framework that prioritizes capital preservation before designing contractual returns and equity upside.
