Like other accelerators, Techstars, a network of more than 40 corporate and geographically targeted startup bootcamps, has had to bring its marquee demo day events online.

Over the last two weeks of April, industry-focused accelerators working with startups building businesses around mobility technologies (broadly) and the future of the home joined programs in Abu Dhabi, Bangalore, Berlin, Boston, Boulder and Chicago to present their cohorts.

Each group had roughly 10 companies pitching businesses that ran the gamut from early-childhood education to capturing precious metals from the waste streams of mining operations. There were language companies, security companies, marketing companies and even a maker of a modular sous vide product for home chefs.

The ideas were as creative as they were varied, and while all seemed promising, about two concepts from each batch stood out above the rest.

What follows is our completely unscientific picks of the top companies that pitched at each of these virtual Techstars demo days. In late May or early June, expect to see our roundup of the next batch of top picks from the their next round of demo days.

Hub71

Techstars’ inaugural cohort for its accelerator run in conjunction with Abu Dhabi-based technology incubator Hub71 included a number of novel businesses spanning climate, security, retail, healthcare and property tech. Standouts in this batch included Sia Secure and Aumet (with an honorable mention for the novel bio-based plastic processing and reuse technology developer, Poliloop).
