"It is an honor to continue and significantly grow the impact we are having at J2 Ventures with our latest fund," said Alexander Harstrick, Managing Partner of J2 Ventures. "The growth of our portfolio, the doubling down of existing LPs, and the attraction of some of the most sophisticated institutional investors is a great confidence boost. There is not only appetite for our model but a strong and rapidly growing interest. We are truly just getting started."
J2 Ventures has invested in over 25 companies, often drawing coinvestment from top-performing generalist venture capital funds. Notable among their investments are companies like Aalyria, Micron Biomedical, and Lumia Health, where J2 Ventures is the sole institutional financial backer.

I have not been disappointed; J2 Ventures has done more than hold up their end of the deal."
