Jutta Friedrichs

Walk into Cambridge's Kendall Square and look down. Past the puffer coats and the laptop bags, past the Dunkin' cups - there it is, a slab of slate-colored solar panel, a digital display showing the next Red Line train, the weather, a community message about a block party on Saturday. The four bolts holding it in place are the only visible engineering. The rest is software, hardware, and one specifically German conviction about how cities should behave. The conviction belongs, in part, to Jutta Friedrichs.

Friedrichs co-founded Soofa in 2014, alongside Sandra Richter and Nan Zhao. The company spun out of the MIT Media Lab and Harvard, set up shop on Thorndike Street, and started installing solar-powered, plug-and-play city signs in towns that wanted to be smarter without first having to rip up the pavement. Her title at the company has moved around the way titles do at a sixteen-person hardware startup. Co-Founder is the constant. VP of Operations is the official one. The work, however you label it, is the same: get a complicated object made, shipped, mounted, talking to a server, and looking good on a sidewalk in February.

You can read Soofa's pitch in a sentence: solar-powered communication tool for cities and advertisers. You can also read it in four bolts. Friedrichs and her co-founders made a deliberate bet that the most useful smart-city object is the one a city worker can install before lunch. No trenching. No grid hookup. No software contract that takes eighteen months to clear procurement. Just a thing in the ground, blinking politely, doing the thing.

That quote is the whole company in one breath. While the rest of the industry kept teaching thermostats new tricks, Friedrichs and her co-founders went outside. The Soofa Bench - the company's first product - was a charging station you could sit on. Lab numbers, then deployment numbers: an average of 17 people charging for 12 hours per bench per day in the early installs. The benches drew strangers into the same orbit, gave them a reason to linger. Public space, the company implies in its hardware, is software too. It just runs on bodies.

The standard founder story starts with a dorm room. Friedrichs's starts with a doll house. She designed her first elaborate one at age 8, the kind of detail people only mention later, when the doll house turns out to predict the career. From there: London. Central Saint Martins College of Art and Design, BA in Product Design, class of 2005. The same year, while her classmates were sorting out studios in Hackney, Friedrichs got recruited to Shanghai. The Dutch retailer Xindao wanted someone to co-found its in-house product design department. She went.

Two years in, she launched her own studio, MÜ Furniture. The line drew on Chinese Ming furniture - minimal, slightly austere, with an abstract reference to nature that critics could not quite stop writing about. Wallpaper magazine ran her. Elle Decoration gave her an award in 2009. The Red Dot jury handed her two awards in 2008 - one for a solar torch, one for a laptop bag. The iF Design Award followed in 2011. There is a version of this resume where she becomes a furniture name and stops there. She did not.

Instead she applied to the Harvard Graduate School of Design. Master in Design Studies, 2010 to 2012. While at Harvard she entered the Business Plan Competition with a concept called "Ubiquitous Energy" - affordable solar phone chargers, basically the spore from which Soofa would grow. The pitch finished as a runner-up. The idea did not finish at all. It kept going.

By 2014 the company was real. Sandra Richter and Nan Zhao - the latter a Media Lab PhD - signed on as co-founders. The team set up in Cambridge. They built a bench. Then they built a sign. Then they built a network of signs. Today the Soofa Sign is the leading solar-powered communication tool for cities and advertisers across the United States. It displays public transit times, weather, civic events. Anywhere under the sun, four bolts.

Most consumer technology has reached its endgame. The phone is solved. The laptop is solved. The TV is solved. What is not solved is the city: the bus stop with the wrong arrival time, the empty bench nobody charges from, the kiosk advertising a movie that came out last August. Friedrichs's bet, and Soofa's, is that the curb is the next interface - that whoever turns it on first gets to define how cities talk to the people inside them.

This is not a glamorous bet. It involves permits. It involves city council meetings, which run long. It involves making sure a solar panel keeps a screen alive in a February cold snap in Worcester. It involves selling to procurement departments who measure their patience in fiscal quarters. None of it photographs well. All of it matters.

Friedrichs's design CV makes her recognizable in furniture circles. Her Harvard credentials make her recognizable in Cambridge. The combination is rarer: a person who can sketch the curve of a kiosk, sweat the bolt count, and translate the spec into three of the five languages she speaks. Soofa's signs are quiet products. The thinking inside them is not.

Ask her about smart cities and she goes back to that phrase: most smartness has been built for the home or the phone. The sidewalk got skipped. She did not skip it. That is the whole pitch, told slowly.
