Fredericton-based accelerator Energia Ventures will hold its second demo day of 2021 on Dec. 9, showcasing a roster of five companies from four countries.

Energia is hosted by the University of New Brunswick’s Technology, Management and Entrepreneurship program and supports startups from around the world involved in energy, smart grids, cleantech and cybersecurity. The program is in its fifth year and for the first time is offering two cohorts in 2021.

The virtual demo day starts at noon and you can register for it free here.

Here’s a look at the startups participating in the second cohort of this year:

AllRead (Barcelona, Spain) - AllRead is developing deep learning models for reading text in uncontrolled environments -- that is, in the real world, outside of the laboratory conditions where most artificial intelligence systems for reading thrive.

Gaia Refinery (Saint John) - Gaia is working on technology to remove carbon from the atmosphere via direct air capture and use it to produce high-purity methane for the space industry.

Prakshep (Bengaluru, India) - Prakshep helps agriculture companies use neural networks -- a form of artificial intelligence inspired by the structure of the brain -- to automate their activities with the help of satellite imagery and machine learning.

Privacy Optimization (Warsaw, Poland) - Privacy Optimization helps organizations navigate the complex landscape of privacy regulations via audits, consulting services and advice for better protecting the privacy of end-users.

WeavAir (Toronto) - WeavAir sells air filtration equipment to slow or prevent the spread of airborne contaminants and pathogens, while also reducing maintenance costs and cutting HVAC energy consumption.
