Techstars has launched another “powered by” accelerator, this time with Sprint around mobile health. It’s based in Kansas City (Sprint’s headquarters) and is our fourth powered by Techstars accelerator, joining Nike, Kaplan, and R/GA. I’m an enormous fan of four things about the Sprint Accelerator – what we call “PBTS” (powered by Techstars), mobile health, Kansas City, and Sprint. The PBTS strategy is one we started working on in 2012. We knew that we would continue to expand Techstars geographically (in 2013 we’ve added London, Austin, and Chicago). At the same time we were talking to a lot of large companies with outstanding brands about building accelerators specifically around their ecosystems. It dawned on us that the dynamics of an accelerator could work as well for building innovation and new company’s around a particular company/product ecosystem as it could for a city. So far the results have been awesome with outstanding companies coming out of the Nike+ Accelerator and the Kaplan EdTech Accelerator.

Last week, in the midst of Denver Startup Week, we had a full day Foundry Group Exec conference. Ben Deda from FullContact convened about 100 execs from our 60 or so portfolio companies for the day. We had seven topics of one hour each, led by a different set of execs. The result was an incredible range of discussions across an amazing group of people. One of the attendees was Jeff Malek, the CTO of BigDoor. Jeff is super passionate about what he does and mixes humor with intensity with math. Following is something from Jeff to kick you in the ass this morning and get you charged up. 

Did you know Twitter is going public? Of course you did – it’s all the mainstream media could seem to write about last week after the now infamous twitter tweet about it. We’ve confidentially submitted an S-1 to the SEC for a planned IPO. This Tweet does not constitute an offer of any securities for sale. — Twitter (@twitter) September 12, 2013 After all the speculation about valuation, who owns what, what it’ll price at, how much money will be made, is Twitter growing or shrinking, what is a tweet after all, will their stock symbol be TWIT?, and all the other nonsense that seemed to consume the business press, I noticed a perplexing thread from some people expressing how indignant they are they Twitter is going public in secret.

Yesterday Yesware announced that Battery Ventures led a $13.5m round that we participated in. A few days ago Xconomy wrote a great article about the very first Yesware board meeting on April Fools Day, 2011. When I reflect on the journey of Yesware over the past 2.5 years it’s a pretty awesome example of a company going from a seed investment with three founders (Matthew Bellows, Cashman Andrus, and Raj Bhargava) to a rapidly growing 40 person company.

I was going to blog about the Yesware $13.5 million financing but I’ve been buried in Denver Startup Week so I’ll do that tomorrow. I’ve continued to be emotionally distracted by all the devastation around Boulder from our recent floods. I’ve gotten a ton of emails from all over the world in support as well as some meaningful financial contributions adding on to the $100,000 my partners and I just gave to the Entrepreneurs Foundation of Colorado to provide direct support for the flood victims.

I love being involved in magical stuff. One of our portfolio companies, Occipital, just announced their newest product, the Structure Sensor. It’s available for purchase right now on Kickstarter – they blew through their $100k goal in the first four hours of being up. But this is a “show don’t tell” classic, so take a look at the video below and prepare to have your mind blown. So awesome. Jeff, Vikas, and team – you guys are amazing.

Today, my partners at Foundry Group and I are contributing $100,000 to the Entrepreneurs Foundation of Colorado (EFCO) to help with the Boulder Flood Relief Effort. This is our second gift to the EFCO – we previously contributed a portion of our carry across all of our funds. The floods in Boulder and the surrounding area the past week have been devastating. I went for a run last night around town just to get a feel for things – the water is still at dangerously high and fast levels in Boulder Creek and the damage near the creek in downtown is visible. I smelled smells that I’ve never smelled in Boulder before and saw water in places it simply didn’t belong.

In 2007 when I co-founded Entrepreneurs Foundation of Colorado with a bunch of folks our mission was to create wealth that we could give back to the community that has been the foundation for so many of our entrepreneurial endeavors. We envisioned that this would be a long term build, just like the creation of many of the companies we are involved in. Over the last six years we’ve now generated gifts of over $500,000 that have gone back directly to our community, with the most recent one being from Intense Debate, a company that went through Techstars Boulder in 2007.

Amy and I took one of our Qx vacations last week – where we go off the grid entirely for the week (no phone, no email, no computer stuff). We were originally going on a walking trip to Prague with some friends, but decided we needed 12 hours of sleep a night for a week so we gave our trip to some other friends and headed to Vail to hide out for a week in a fancy hotel with room service and a spa.
