Kula Bio is a Boston based startup that is making organic and sustainable nitrogen through nitrogen fixing microbes that can replace synthetic nitrogen and the Haber-Bosch Process. The technology comes out of Dan Nocera's lab at Harvard. Currently, nitrogen fixing microbes cannot survive in the soil for very long because they get outcompeted. Kula Bio gives these microbes an advantage by "supercharging" them. Basically part of the mass of the microbes in converted into a bioplastic that functions as a battery and supplies energy to the microbes enabling them to live for weeks instead of hours. Kula's technology is plant agnostic and they can feed any type of crop since they produce nitrogen in the soil and not in the plant. Because the microbes only produce nitrogen when it's needed, there is no nitrogen runoff.

Why We Invested

  • CEO is a seasoned entrepreneur that has deep experience in scaling and selling commodity chemicals. He's a great storyteller and fundraiser. 
  • Large global market.
  • Strong go-to-market strategy with an attractive beachhead market, organic nitrogen, which can sell at 10x the price of synthetic nitrogen.
  • Strong barriers to entry through patents and know-how. 
  • Trials have shown great, consistent results in a wide variety of crops, soil types and both in greenhouse and in the field. Consistency and lack of wide applicability is a major issue with biologicals and Kula does not seem to have this problem.
