TL;DR
A pitch deck is a short slide presentation, usually 10 to 15 slides, that founders use to explain the problem, the product, the market, the team and the ask to a potential investor.
What pitch deck means
Standard sections cover the problem, your solution, market size, product, traction, business model, competition, team, and the specific ask, how much you're raising and what it funds. Investors typically spend only a few minutes on a first read, so the deck has to communicate the core story fast, with detail available for anyone who wants to dig deeper in a follow-up conversation.
There are two versions most founders end up building. A narrative deck is meant to be presented live with a founder talking through it. A leave-behind deck carries more text and detail and is meant to be read on its own after a meeting or before an intro. Conflating the two is a common source of decks that are either too sparse to stand alone or too dense to present well.
Why it matters for African founders
The Trampoline Founder Stack's scanner reads your public site and, where uploaded, your deck itself, to flag readiness gaps before you send it to a fund. The same gaps that trip up a scanner, missing traction numbers, unclear market sizing, a vague ask, are usually the same things a real investor flags in their first read too.
Common mistakes founders make with pitch decks
- Burying the actual ask, amount raising and use of funds, at the very end instead of stating it clearly early
- Presenting vanity metrics instead of the numbers investors actually track, retention, revenue growth, CAC
- Using a market-size slide with no defensible sourcing behind the number
- Sending a narrative deck as a cold leave-behind with no one there to explain the gaps between slides
