I don’t want to waste time on angels who aren’t actively investing. Who are the most active angels and super angels? What’s the best way to find out this type of information?

Bloomberg Top Angel Investors:
This article just came out in San Francisco Magazine:
These guys have the power to swoop in from on high and grab the deals that lesser angels can only envy.
How big is his fund: $950 million total, in two funds.
Cred: Serves on boards of eBay and Facebook; chairman at Ning, which he cofounded in 2005; cofounder of Netscape, which launched the dot-com boom.
Seeds: 28 currently (before that, he and cofounder Ben Horowitz invested in many other companies going back to 2004).
How he thinks: “I sit down at my desk before I go to sleep, pull up my to-do list…and pick out the 3 to 5 things I am going to get done tomorrow. I write those things on a fresh 3×5 card, lay the card out with my car keys, and go to bed. Then, the next day, I try like hell to get just those things done. If I do, it was a successful day.”
Super bets: Aliph; LinkedIn; Twitter; Foursquare.
Twitter followers: 3,898.
Typical tweet: His one and only tweet, back in 2007, was “twittering!”
How big is his fund: $20 million.
Cred: A rep so towering that 5,000 or so people refer deals to him.
Seeds: 500, with more than 200 exits.
How he thinks: “I love it when we invest in a company with an 18-year-old because it’s going to be much more exciting. The world is their oyster, and anything’s possible in their minds. That is the best entrepreneur ever.”
Super bets: Google; PayPal; Ask Jeeves; Good Technology; Facebook; Zappos. (But he turned down Salesforce.com, to his eternal regret.)
Twitter followers: 1,953—though he has yet to tweet.
How big is his fund: $20 million of Greylock’s money to play around with.
Cred: Cofounder of LinkedIn; former exec at PayPal.
Seeds: 80+ investments (and that’s pre-Greylock).
How he thinks: “Few business plans ever pan out like their owners intend. PayPal started as a plan to beam payments between Palm Pilots…. After five minutes of a pitch, I know if I’m not going to invest, and after 30 minutes to an hour, I generally know if I will.”
Super bets: Facebook; Zynga; Digg; Flickr.
Twitter followers: 16,015.
Typical tweet: “What is hard about making decisions: making decisions reduces opportunity in the short term. but decisions mean long term opportunity.”
How big is his fund: $250 million.
Cred: Cofounder of PayPal; first outside investor in Facebook.
Seeds: Hard to say, but 36 through Founders Fund alone.
How he thinks: “The angel-VC thing feels very crowded. To invest, you want to always be fundamental and contrarian, and while I think there’s a fundamental story of how the Internet’s going to grow,
it’s not as contrarian as it was three or four years ago.”
Super bets: Facebook; Twilio; SpaceX; Spotify.
Twitter followers: 420, also without posting a single tweet.
Vets of some of web 2.0’s biggest success stories, they’ve proved over and over that they still know how to pick ’em—for themselves and for their investors.
How big is his fund: Unknown.
Cred: Kleiner Perkins; Starbucks; Microsoft; eBay.
Hit rate: 10 exits.
How he thinks: “Don’t worry so much about figuring out the ‘path’….Make decisions. Go. Try.”

Twitter followers: 564.
Typical tweet: “Open tweet to @mikebloomberg: Please can’t you come to California and be the governor?”

Hit rate: 6 exits.
How he thinks: Referencing Godzilla, he looks for “Thunderlizards”—“a company that disrupts its industry, earns a 100-fold return, and makes up for all of a fund’s bad bets.” But of consumer Web 2.0, he warns: “It’s starting to get a little played out.”
Super bets: Chegg (textbook rental site); Digg; Twitter; partnering with Stanford lecturer Ann Miura-Ko (according to Forbes, “the most powerful woman in startups”). He was also an entrepreneur in a broadband-software play that IPO’d in ’04. But nobody’s perfect—he passed on Zynga.

Typical tweet: “Pondering: which eagles song was better ‘sad cafe’ or ‘new kid in town’? A very tough call…”
How big is his fund: He’s raising $30 million.
Cred: One of those PayPal mafiosos.
Seeds: 100 in the past 2.5 years.

Super bets: Twitter; DailyBooth; Posterous; 280 North (acquired by Motorola).
Twitter followers: 1,305,712.

VC deals: Amazon; Google; Intuit; Compaq; Amyris Biotechnologies; Bloom Energy.

Cred: Former Kleiner Perkins entrepreneur-in-residence; former CEO of IronPlanet (annual gross $500 million); brought Facebook to Accel.
VC deals: Groupon; BranchOut; Metacafe (whose cofounder Eyal Hertzog has said, “Working with [Efrusy] is the first time I’m getting real value-add from a VC”).
How he thinks: “You have to pick your poison, take risks, and stick your neck out—that’s what our business is about….We try to do things that are really, really early and help build these teams when we can.”
How big: $480 million in Accel’s growth fund alone.
Cred: Former Sequoia Capital partner; led deals with eHarmony and Gracenote (sold to Sony for $260 million).
VC deals: Dropbox; StumbleUpon; Quidsi (parent company of Diapers.com and Soap.com).

VC deals: Bump; ImageShack; Loopt; PowerFile; RockYou—and the hottest incubator out there, Y Combinator.
How he thinks: “At the end of the day, without that great [market] wave, even if you’re a great entrepreneur, you’re not going to build a really great business.” The company should be able “to create an inferno with a single match.”
How big: The firm is huge; as an individual angel, he’s planning at least four deals at about $500,000 each this year (or so he told AngelList).

VC deals: Bitfone; Good Technology; Ingenio; LogMeIn; Opsware; Tellme; iLike.
How he thinks: “My perspective on angel and VC investors is shaped by my own experiences as an entrepreneur on the firing line, trying to get revenue in the door.” He looks for “companies [that] aspire to be worth billions.”

Cred: YouTube’s first user-interface designer; preparing to launch TheIceBreak (“I can’t give too many details, but it’s relationship focused”).

Deals to date: Around 50, with 10 or so exits.
How he thinks: “There’s a tendency for [angel wannabes] to say, ‘Wow, that’s really great’ and want to put in all their money. You shouldn’t invest anything that you would mind losing.”
Best bets: 280 North; Y Combinator; Opzi; Rapportive; ReMail (acquired by Google); AppJet (ditto); Optimizely.
Cred: Ex-Facebook and -Apple; CEO of Napster founder Shawn Fanning’s hot new startup, Path.
Deals to date: 18.
How he thinks: “Technology will continue to move faster than our ability to set public policy within our current processes. How do we evolve the process to support innovation?”
Best bets: Formspring; Foodspotting; Trazzler.
Cred: Investing since 1996; former chair of StumbleUpon; CEO of TextMarks.

Deals to date: 47.

Best bets: Foursquare; Square; DailyBooth; Bump; Etsy.
Cred: Early hire at Google; cofounded XG Ventures in 2008.
Deals to date: 25, with 5 exits.
How she thinks: “I think there’s greater opportunity than ever right now. The holy grail for me is a local ad-targeting play that really works.”
