Millie Tadewaldt

Hi! I'm Millie.

I’m an entrepreneur in San Francisco. I'm interested in simplifying decisions, building compelling brands, and genuine customer service. I enjoy computers, sunshine, swimming pools and pranks.

I run Brilliant, a tech-focused corporate gifting and branded merchandise company. We help companies give amazing gifts to their clients and colleagues. It's a pretty fun gig.

Previously, I was part of the team at AngelList, helping startups raise money and people invest in startups. In the year we launched syndicates, we helped startups raise over $100M. I was also co-founder and CEO of CakeStyle, a high-touch, high-end personal styling service for busy women, and one of the first "fashion in a box" companies out there. You can learn more about it in TechCrunch (here and here), on CNBC, in Refinery29, in the Washingtonian and in this quick video.

Before that, I ran the Foundry at Sandbox Industries where we developed a systematic approach to identifying startup ideas, and launching/investing in the most promising ones. I helped build and grow a number of different companies including doggyloot (acquired), Lab42, Lost Crates and GetAFive (acquired).

I’ve also worked at The Boston Consulting Group, studied law at Harvard, studied design at UC Davis, started my first business when I was 20, and taught myself to code as a teenager.

I am married to this fantastic human and mom to a grip of adorable tiny people.
