Every month at USV we have an internal hack day, where we work on various fun tech projects. We hack on USV.com, we build internal tools, we play with fun new hardware, try out new APIs, etc. It's a nice change of pace, and an opportunity to get a little closer to the tech we spend most of the time talking about. One area we've spent some time on recently is building tools for the USV Network. We have about 60 active portfolio companies, and it's Brittany's job to help them learn from each other as much as possible. She's the human router within the portfolio, matching up skills, questions, needs, and experiences. As part of that, she runs over 50 peer-driven summits ever year across functions (engineering, mobile, people, trust & safety, etc), where members from each company come together to talk shop. Each summit produces a long list of notes, follow-ups, questions, contact info, etc. One persistent problem has been making that document accessible, hackable and shareable, both during the summits and afterwards. Version 1 was a google doc later ported into a Yammer document for archiving. We recently moved the portfolio network from Yammer to Slack, where we are now approaching 1000 members. As part of that, we decided to see if we couldn't hack something together using the Slack API to easily share docs across this large and diverse group. Last Hack Day, we built a "login with Slack" workflow into USV.com, and created a simple CMS for group-editable documents using Firepad (an excellent open source collaborative document engine built on Firebase). After doing that, we realized that it would be just as easy to open this up to anyone, regardless of their Slack team, and the result is Quackpad:

It's very simple: go to Quackpad.io and sign in using your Slack account. You can create a simple group document that's immediately shareable with anyone else who is a member of that Slack team (and not to anyone else). It's particularly good for Slack teams made up of people from across organizations, who wouldn't otherwise have an easy way of sharing docs privately (vs., say, a company, where everyone is on gApps). This is alpha software! So use at your own risk and let Brittany and me know if you run into any trouble. Big props to: Michael Lehenbauer from Firebase, the primary author of Firepad, the whole USV team and network for helping build this and test it, and Slack for having a really nice API to work with. Enjoy! (and vote it up on Product Hunt!)
Today, we announced that USV is investing in Hailo. I am psyched about this for a number of reasons, but primarily because it’s infrastructure that connects people to their city in new ways. What’s most fascinating is that we almost certainly don’t yet know what those ways are. I want to point out one quote from Fred’s interview in the Wall Street Journal. He says:
“We think this is a kind of Trojan Horse to get people using a large network on their mobile phones to actually transact and get real stuff,” said Fred Wilson, managing partner at Union Square Ventures. “From there, I think lots of interesting things can happen. Alone in the taxi cab market, there’s a pretty big business to be built, and the fact that there’s potential beyond that gives us a lot of confidence.”
We talk a lot about backing into your network - in other words, starting with a thin edge of the wedge and ultimately finding a secondary purpose that may in fact be more profound than the first. For instance, we often say “twitter backed into identity” — when Twitter started out, it didn’t start by announcing itself as the de facto identity provider on the web. Instead, it became that after achieving ubiquity in public messaging. Relatedly: a few weeks ago at the
