Anthony Sagneri grew up in Syracuse, New York and graduated from Rensselaer Polytechnic Institute in 1999 with a BS in electrical engineering during which time he was involved in ROTC. After graduation, he spent 5 years in the U.S. Air Force, rising to the rank of Captain and led a team of 70 intelligence operators to 169 collection missions worldwide. After returning to civilian life, he attended MIT for his masters and Ph.D in electrical engineering.

In 2010, Sagneri co-founded FINsix with MIT classmates Vanessa Green, George Hwang and Justin Burkhart based on Very High Frequency (VHF) technology he helped develop in professor David Perreault’s lab. Sagneri’s doctoral thesis, titled “Design of miniaturized radio-frequency DC-DC power converters” formed the basis of FINsix’s (formerly OnChip Power) products. Sagneri’s circuit converts power at a very high frequency, up to 1000x higher than those used in conventional adapters, with no efficiency penalty. The faster one can switch power, the smaller the container can be, minimizing the size, weight and cost of the system.

As OnChip Power, the group raised $1.8 million in venture funds while enrolled in MIT course “Entrepreneurial Finance.” FINsix’s first commercial product, a laptop power adapter called Dart, was unveiled at the 2014 Consumer Electronics Show in Las Vegas. FINsix raised $7 million in venture funding and a successfully completed a Kickstarter campaign, which raised over $450,000. Since FINsix had already raised a large amount of capital, they used the Kickstarter campaign to identify and connect with early adopters in order to learn and grow based on customer feedback.

Lessons Learned

Examine all options. The company's original plan to create better LEDs or use envelope tracking to improve cell phone batteries did not work out due to markets flooded with startups. The team had to think creatively to find novel ways to use Sagneri's technology, but eventually found a piece of consumer technology that had not been updated in decades, the laptop adaptor.

Inspiring Quotes

Anthony Sagneri's Quotes

The idea is to help people reimagine the power delivery in their systems. In places where that’s a bottleneck — which it continues to be, as devices get more dense and capable — it helps the rest of technology progress.
