Ukrainian venture capital fund AVentures Capital has sold a stake in cybersecurity startup Spin.AI after the American fund K1 entered the company. The fund called the deal the largest in its history.
This was written by AVentures founder Andriy Kolodyuk on his Facebook page, where he announced the sale of a stake in cybersecurity startup Spin.AI. The fund clarified that they did not completely exit the company, but called this deal the largest for them since the launch.
Spin.AI is a startup with Ukrainian founders that started in Odessa and specializes in cloud services security. AVentures said that they entered the company back in 2017 as the first institutional investor and then invested $500,000. Later, the fund continued to support the startup in subsequent rounds and helped attract other international investors.
Now Spin.AI has received an investment from the American fund K1. AVentures noted that K1 manages assets worth $20 billion, and the deal itself was called the largest investment in a cybersecurity company with Ukrainian founders. The amount of the new round is not disclosed in the post, but they emphasize that for the fund itself this is an important partial sale and the result of a long-term bet on the team.
In the post, AVentures explains that it invested in Spin.AI back when SaaS security was just starting to emerge as a separate category. The logic was that as companies increasingly moved to Google Workspace, Microsoft 365, and other cloud platforms, the need for new cybersecurity tools grew.
The fund directly called this story proof that investing in Ukrainian founders building global products can bring great results. In the post, AVentures noted that the deal was a successful investment and a partial exit for both the fund itself and its investors.
For the Ukrainian startup ecosystem, this is a case study also because it is not just a new round, but a rare public example where a local fund that entered a startup at an early stage was able to partially capture the result after the entry of a major American player.
