“There has never been a better time to take a long-term view and use technology to solve major problems, and we’ve never needed the solutions more than we do right now.” - Sam Altman, Hard Tech is Back, 11 March 2016.

A new supersonic jet. A robotic lab assistant. A telecoms satellite that fits in your carry on. This isn’t science fiction. This is YC making good on their promise to seek out more founders that want to solve major problems. YC knows that despite their access to some of the best early stage investors, hard tech is still a hard sell. But the Hard Tech cause might be helped by YC’s second billion dollar exit. Cruise, a hardware and software company that makes self driving car tech, was recently acquired by GM.

Despite YC’s track record and access to some of the greatest early stage investors, hard tech is harder to fund. This has been our experience too. In fact, it’s often the case that one of the final discussion points on an investment is what happens when they struggle to put together a seed round? It’s not always going to end happily, but Urban.Us exists to get more hard tech into the service of cities, so we’ll frequently take on the risk and try to find creative ways around it. This is one of the reasons we send these updates and why we’re beginning to organize Angel.co syndicates.

P.S. We’re sharing more frequent updates on Facebook!

P.P.S. Maybe writing will be replaced by Snapchat videos. Until then, The Economist has your back with six little writing rules from George Orwell.

P.P.P.S Why do we mark our updates in weeks (like WK112)? We’re inspired by the Wait But Why Life Calendar.
