Helen, what is the specific outcome of these pitches? Is to secure funds immediately, or to move into a next round?
Get very focused on that outcome. What do they need to know to move forward to that next step?
Remember we all buy a solution first-the details don't matter until they believe the problem and the potential of your solution.
In five minutes, every word counts. I agree with Bob - go watch Roses TED talk...again...
They're giving you 10 minutes in q&a so they can ask about the facts that matter to them. That being said, I would spend my time:
1 minute framing the problem, why it matters, and the size of the market
1 minute on the what the general solution would be -the result you're trying to accomplish and why it's the answer
1:00 minutes on how you bring that solution to fruition- give a case study
30 seconds on overall results so far
30 seconds on your projections or next steps.
20 seconds on why you're the person to do it (and that is you, not your organization, you.)
15 seconds on the key people on your team that complement you
40 seconds on what you need, and the call to action
Get them excited!
Then know you're numbers, know your numbers, know your numbers.
They're going to ask.
