  • Access beyond the US, particularly to European markets 
  • NO EQUITY TAKEN!! And FREE to participate 


While MassChallenge supports a wide array of early to late-stage startups – the Decarbonization program is designed to support early-mid stage companies that possess a validated product/solution ready for scaling. See a more thorough breakdown of the criteria below:

  • Series A - working towards investment round or achieved 
  • Have generated revenue in the last 2 years (not being profitable is accepted)
