Today is day four of Seattle Startup Week, a celebration of the local entrepreneurial community’s accomplishments and bright future. On day one, we introduced you to virtual reality startups Doghead Simulations and ensoVerse, on day two to video game company Strange Loop Games, and yesterday to two IoT startups, Smashing Ideas and Pebblebee. Today we’re putting the spotlight on three artificial intelligence  companies: Mona Labs, Ario, and Dimensional Mechanics.

The people at Mona Labs are making shopping a lot less overwhelming and a lot more efficient, both time-wise and money-wise. The app, an AI-powered personal shopper which has been featured in the iTunes App Store four times, learns your shopping preferences by analyzing your feedback and e-receipts, and then recommends new products through a conversational user interface. Users can directly shop from over 1300 designer brands with a one-click purchase and free shipping.

“Our vision is to provide the most personal and delightful shopping experience in the world,” said Director of Marketing and Business Development Paolo Sciarra. “We have trained our models with more than 100 million behavioral customer data points and we achieved the highest conversion and engagement metrics in e-commerce. Mona is one of the most advanced personalization products in the market today.”

Ario also seeks to help balance the lives of its customers, but from a well-being standpoint. The startup has created what they call the world’s healthiest smart lamp.

“Artificial lights we use every day interrupt natural hormone production and throw off our body clocks, leading to long and short-term health consequences,” said Zim Hang, Director of Marketing and Operations. “Ario is the first lamp designed to keep your body clock in sync to help manage healthy body weight, reduce stress, increase powerful antioxidants, boost the immune system, and improve overall health.”

The product, which uses cloud-based machine learning to deliver lighting optimized to the user, is based on over 15 years of research from Harvard Medical School, NASA, and the NIH.

“What’s most exciting is that we’re on the cusp of a whole new paradigm of lighting—imagine data flowing not just through radio-frequency bands, but also through the lighting systems around us,” the spokesperson said. “It’s going to change how devices in our homes and across the world communicate.”

Dimensional Mechanics is also developing a cloud-based AI operating system called NeoPulse™, which makes it possible to develop pre-trained AI models without needing to be an AI- or machine-learning expert.

“We have brought together a highly skilled, inter-disciplined team of scientists, researchers, and tech veterans to architect and build a platform that can address some of the most complex data analysis problems confronting the enterprise today,” said co-founder Dave Herbert.

Their products may differ, but these AI startups all have one thing in common: Washington is their homebase.  

“There a significant Big Data/AI-oriented talent pool in the area from which to draw and a well-established, well-connected startup and investor community,” Hebert said.

Hang agreed.

“Washington has a growing ecosystem that’s supportive of new ideas and ventures,” he said. Being the cloudy city that Seattle is, we thought Ario would be perfect to bring the benefits of natural light to people.”

Sciarra had a slightly more pragmatic take.

“As former Amazon employees, Seattle was the obvious choice of where to start Mona. The city is one of the principal hubs for machine learning talent and it’s more affordable than the Bay Area or New York,” he said.
