Most people name a company after a word that sounds good. The founders of a Munich startup named theirs after a feeling: coming home to a warm flat.
The name tado is built from two Japanese greetings. Tadaima is what you say when you walk through your front door: I'm back. Okaeri is what the house answers: welcome back. In 2011, when Christian Deilmann, Johannes Schwarz and Valentin Sawadski started the company in Munich, the first thing their product could do was exactly that. It noticed your phone coming home and turned the heating up.
It has gas boilers, oil burners, district heat, old wiring and new, in every country.
That trick, geofencing, sounds small now. Then it was a bet that people would rather let a phone decide when they were in than program a thermostat, which almost nobody ever did. The first product, tado Heating, reached customers in Germany, Austria and Switzerland in November 2012, and the UK followed in 2013.
The bet was easy to describe and brutal to build. Europe does not have one kind of heating. It has gas boilers, oil burners, district heat, old wiring and new, in every country. By 2014 the box could control more than 5,000 different heating systems, and that is where the early years went: not into slogans, but into integrations. In July 2014 an investor group led by Target Partners and Shortcut Ventures put in 10 million euros. In 2015 the company added a controller for air conditioners and showed it at an event in New York.
Nobody outside the company sees the dull work behind a smart home gadget, but it is the moat. A rival can copy an app in a month. It cannot copy years of knowing how a thousand boilers misbehave.
Money followed. Siemens, E.ON and Amazon were among the backers, and by early 2023 TechCrunch counted around 200 million dollars raised. More than 3 million thermostats had been sold by 2022. The company also bought Awattar, which helps households use power when it is cheap.
Then came the part founders rarely enjoy telling. In January 2022 tado agreed to go public through a SPAC at a valuation of about 450 million euros, later trimmed to around 400 million as markets shook. In September 2022 the partner walked away. Deilmann said the cancellation reflected public capital market conditions. Tado raised 43 million euros privately in January 2023 instead, led by Trill Impact Ventures, and said it aimed for profit that year and had not laid anyone off.
The quiet lesson sits in the name. The founders picked one human moment, coming home, and built everything around making it better. Funding cycles cooled, a listing slipped away, and the company still had something simple to point to: a warm house when you walk in.
