It can take months to get the results of your strategy project, or your business plan. And along with it, your pitch deck has evolved as well. You take it out for every meeting.
A refreshing approach: rewrite the pitch deck (not the business plan of course) from scratch for your next meeting. My guess is that it should only take you 3 hours, since you did all the work over the previous months. A fresh story line, and only charts to support your messages, rather than provide backup data. No risk, if it didn’t work you will always have your old one, but my predication is that that one will start to collect dust.
