Investors

Have enough investors there
Don't hold an entrepreneur education meeting trying to entice angels ("How to raise money 101).
Match the right kind of investor attendees to the right kind of event (angels and seed stage, VCs and early stage)
Hold events where there is a high percentage of investors.
Let the ratio of companies to investors to amount of time make the event very worthwhile.
Invite the VCs who are really looking for the early stage business.
Have an invite-only forum with higher quality and quantity of investors.
Target the individual investor: they are the source of funding for most start-ups and seed stage companies.
Create a demo/pitch/entrepreneur groveling that gets angels to come out and spend two hours of their time.
Target the investor who is interested in hearing about new startups but doesn't attend current forums or angel groups.
Give angels more than a weeknight event based on what entrepreneurs want.
Ask angels what they want.
Help angels with the steep learning curve
Help angels avoid losing their capital

Some Tips Re: Angels

Reality: 3-6 solid leads out of an angel is average.
Reality: angel deals come together because 2-3 angels connect on their diligence & interest in roughly the same time, momentum builds, and others who have worked with the 2-3 individuals get on board the train.
Angels invest because someone they trust is investing.
Even the most active angels (who aren't named Ron Conway) will do maybe 2-3, deals a year.
That's about all a serious angel can deal with in terms of involvement.
Investment is not a quantity type of game -a couple of quality experienced angels trumps a dozen "I really liked what I heard - I've never made an investment in a startup before but I'd like to learn more".
The age old VC metric is "one deal per GP per year".
Very few angels in this geography have as many as 5 total investments. Very few.
It is better to get a referral to an angel than to pitch at an event; it means someone has vetted the deal and is willing to exert some personal cred fronting it to others.
Find a way to stand out from the noise.
Truth be told, not many angels are making investments right now.
Look towards VCs that claim to do early stage for the funding I


Angel Database

Something that STS should consider facilitating is the creation of an UberAngel database - who is involved with what deals.
Unlike VCs, angels don't tend to be very vocal about what they're involved with (no websites, no desire for "deal flow", etc.)
Someone would have to moderate access, use, privacy and such but it seems like a list of "50 active angels in Seattle" would be a benefit to the community, so long as those 50 saw some benefit in being "outed".
An angel database is a good idea.
The Angel Oregon event used the AngelSoft.net program. It acts as an exchange mechanism. and it creates a database of deals. Perhaps that is a tool that is worth exploring. http://www.angelsoft.net
