Hawa Dawa monitors air quality block-by-block to help cities make decisions

 

If city governments had a block-by-block understanding of their city’s own ever changing air quality, how might it impact the decisions they make?

Thats the concept behind Hawa Dawa, the first company pitching today in the TechCrunch Disrupt Berlin Startup Battlefield. Hawa Dawa combines data sources like satellites and dedicated air monitoring stations to build a granular heat map of air pollutants, selling this map to cities and companies as a subscription API.

While the company notes it’s hardware agnostic, it does build its own IoT sensors for companies and cities that might not have existing air quality sensors in place.

(Curious about the name? Co-founder Karim Tarraf tells me it’s roughly based on the words for “air purity” or “air medicine” in a number of languages, including Swahili, Turkish, and Persian.)

The State Encourages ICO Fraud. The Free Market Minimizes It  

Many Initial Coin Offerings (ICOs) have been and are frauds. The state enables this con game in various ways, including the establishment of accredited investors and the regulation of businesses that sell equity. Shut off from the most lucrative aspects of investment, average people rush into the few sources of profit still available to them. ICOs are a prime example of how state interference in the market increases the risks of doing business.

Sweet Flower Aims To Destigmatize Cannabis Shopping

Their latest store in downtown LA is bright, open, and friendly.

Opinions expressed by Entrepreneur contributors are their own.

It’s no secret that cannabis has a long and colorful association with all sorts of artists, from Shakespeare to Snoop Dogg. And whether you think smoking weed makes people creative, or creative people just like smoking weed (hey, can’t it be both?) clearly there’s a connection here.

Which is why it seems only natural that cannabis companies are finding their way into the LA Arts District. The latest to plant a flag downtown is Sweet Flower, whose newest dispensary opened November 21st — and it may not be the biggest or the splashiest, but it’s certainly one of the nicest.
