The transformation currently underway in Boston is multifaceted — development is booming, population is growing and its weather continues to be a factor. Entrepreneurs have taken notice, and startups with innovations focused on building are popping up around the city.

More than 70 companies around Boston are focused on construction, real estate technology, smart cities and other similar avenues, venture capital for Borealis Ventures recently told The Boston Globe.

“The most common challenges across the world — sea level rise, urbanization, the affordability of housing, and everything in between — we see it all in Boston,” Jesse Devitte, managing director at Borealis, told the newspaper. “Never before has our modern existence been under the pressure it is under today, with changes in the environment, and billions of people piling into cities. It creates a unique moment.”
