Now in its 16th year, the Marcum Tech Top 40 is the premier awards program recognizing Connecticut’s fastest growing technology companies. The awards recognize technology leaders in six industry sectors that reflect the state’s technology landscape:

  • Advanced Manufacturing
  • Energy, Environment, or Green Technology
  • IT Services
  • Life Sciences
  • New Media, Internet, or Telecommunications
  • Software

Tech Top 40 companies are both privately and publicly held, must have $3 million in annual revenue, and demonstrate a record of revenue growth in the past four years. Companies can also apply for the Accelerator award designed for companies that successfully scaled to $3 million in revenue in fewer than three years.
