Learn to pitch & sell your idea

Inventing an innovation is just the first step.


Whether you’re communicating with investors, potential clients, or B2B partners, you need to get their attention and sell them your idea.


During the acceleration program you’ll get a chance to learn how to:

  • Pitch your idea in 30 seconds, 1 minute, or 5 minutes, depending on the circumstances.
  • Grab and keep your listener’s attention.
  • Talk about your business in a compelling, interesting way
  • Communicate your ideas, business news or events clearly and effectively.
  • Overcome the fear of selling and start doing that naturally
  • Get your audience to follow you, customers to love your idea and investors to trust you and listen to what you have to say with interest.


Simply speaking, you’ll learn how to pitch your idea as if you were born to sell. In a natural, confident and attention-grabbing way.


And pitching is just one of the many business skills that you’ll learn during the academy!

Past participants about #Rethink Cohort

“StartSmart CEE (formerly MIT Enterprise Forum CEE) is a fantastic opportunity for early-stage startups to build the product with a Partner, being financially covered for the whole period and mentored on the most critical topics. This collaborative work gives a deep dive into business challenges and the value that your innovative product can bring. Furthermore, with mentors, it is doable to discover the most working Go To Market strategy tailored for a startup. We got it all during the program; if we could do it again, we would go all in it.”
