About us
Seattle Angel is a group of angel investors and entrepreneurs working to bring more education and transparency to the early-stage capital process. Join us for educational and networking events designed for you to connect with, and learn, from angels and entrepreneurs in the community.
Joining our Seattle_Angel Meetup keeps you in the loop for our communications and allows you to register for workshops/events.
These education sessions sometimes are used to prepare for learning about or executing on a first angel investment -- either accepting one for your company or investing in one as an early investor.
We run a Learn-By-Doing entrepreneur/investor due-diligence program event that matches companies and investors, called the Seattle Angel Conference. More info about this at
www.seattleangelconference.com
We put recordings of the workshops at the YouTube Channel -
