Angel investing alongside VCs while driving more wealth to more diverse founders

3 min readJun 2, 2023


150+ angels in the Sie Syndicate Angel Network are actively co-investing in Europe’s most promising female-led startups.

Sie Ventures was launched in 2021 with the mission to drive more capital into the hands of female founders. After delivering the Sie Catalyst Program and working with many exceptional female CEOs, we realised we can also open these opportunities to angel investors who want to diversify their pipeline and access strong venture-backed deals.

Since starting our company, we have run three notably successful Catalyst Programs, built a strong founder community and supported our companies to raise over £70m in capital. We have launched the Sie Raise Summit, run a series of value add sessions for investors and founders and brought the founder and investor ecosystem together to level the funding playing field.

Over the past year, we have invested into seven exceptional female-led teams, welcomed over 150+ angel investors to the Sie Syndicate and co-invested alongside top-tier VCs across Europe, growing the syndicate all through word-of-mouth. We’ve also partnered with a legal firm — Marriott Harrison — to support us with our legal considerations.

Profit + Purpose Investing

We are at the inflection point where women are building the most impactful business across many underserved markets for communities that are in dire need of updated, innovative solutions. In the Sie Syndicate portfolio, out of the three fintechs we have invested in, all of them are improving our world for the next generation — whether it be creating an offering for blue collar workers, or helping more women build their wealth or banking the underbanked.

We don’t need more companies building a faster delivery service, we need to back companies solving real world problems. Investing in purposeful businesses shouldn’t be at the sacrifice of profitable returns and women are often building businesses across both bases.
