We recently attended Web Summit, a conference that brought together more than 30,000 people and over a thousand startups of all sizes. While we were there, we sat down to talk with a few people whose companies aim to make the future brighter.

Our first conversation is with Donnel Baird, the founder of BlocPower, an NYC-based company that "turns buildings into Teslas." BlockPower retrofits residential buildings to wean them off dirty energy and make them green. The second is with Bobby Healy, the founder of Manna, a drone delivery company in Ireland that is replacing gas-guzzling delivery trucks, boosting local business, and making lives much more convenient.

What Could Go Right? is produced by The Progress Network and The Podglomerate.
