How long should a pre-seed pitch deck be?

The main deck should be concise enough to read quickly, usually with detail moved to appendix. Clarity matters more than slide count.

What is the most common pre-seed deck mistake?

Explaining the solution before the investor believes the problem, buyer urgency, founder-market fit, and wedge.

Do pre-seed decks need traction?

They need proof, but not always revenue. Proof can include customer urgency, design partners, pilots, technical progress, founder insight, or early usage.
