The firm's partners have founded and led technology companies including Acronis, Parallels, Acumatica, WebPros and Virtuozzo. The firm reports a combined value of $10 billion or more for companies founded by its partners and more than 25 years of operating experience.

Before and alongside their fund activities, the partners invested as angels and anchor limited partners. The firm reports more than 100 investments over two decades and more than $1 billion invested alongside their operating work. These figures describe the partners' broader experience; they are not Constructor Capital's fund assets under management or fund performance.

The firm reports that approximately 60% of its team hold PhDs and dates its first quantum investment to 2013. Its approach combines technical assessment, connections to research groups and universities, and practical support with fundraising, executive recruitment and customer introductions.

Constructor Capital is part of the Constructor ecosystem alongside Constructor Tech, Constructor Knowledge and the Constructor Start accelerator. The venture capital firm and the wider ecosystem have distinct roles; ecosystem activities should not automatically be attributed to the fund.
