## Questions

### Who runs investment decisions at Advent Venture Partners?

The firm is led by a partnership that has included Peter Baines, Mike Chalfen, and James Mawson over multiple fund cycles. Investment decisions are made collectively by the partnership, a structure typical of European venture firms of Advent's vintage. The partnership has remained relatively stable, with Chalfen and Mawson having been with the firm for over two decades (per the firm's official communications).

### Which stages does Advent Venture Partners typically target?

Advent Venture Partners focuses primarily on Series A and Series B rounds, occasionally participating in growth-stage financings. The firm has historically led or co-led first institutional rounds in enterprise software and life sciences companies across Europe. It does not operate a seed-stage program as a distinct vehicle.

### How does Advent Venture Partners source deal flow?

The firm sources primarily through its four-decade network within European technology hubs, particularly in the UK, Nordics, and DACH region. Its longevity in a market once underserved by venture capital gives it access to founder referrals and repeat-entrepreneur deal flow. Advent does not publicly operate accelerator programs or venture-studio structures.

### What is Advent Venture Partners' exit track record?

The firm has realized exits through both IPOs and trade sales. Notable outcomes include the acquisition of QlikTech by Thoma Bravo and the public listing of Sophos on the London Stock Exchange. Its strategy often involves guiding portfolio companies toward acquisition by US-based strategic buyers, a channel built through partner relationships over multiple cycles.

### Is Advent Venture Partners related to Advent International?

No. Advent Venture Partners is a distinct, independent firm headquartered in London focused on venture and growth-stage technology and life sciences. Advent International is a separate, Boston-headquartered global private equity firm with a buyout focus. The two firms share historical naming conventions common to the era in which they were founded but have no ownership or operational link.
