Hi, Matt S Rinc here and I can help you as in the past for several startups and their pitch decks.
I would need your logo(s) e.g. company and product/service, color scheme if you have branding made and of course business data (contacts, persons, their functions). Especially people background is most important for investors - they see if the people can build/create, market and monetize their knowledge, not just the excellent service/product.
You will also get advice regarding the presentation from 20 years of presentation makeover and public speaking coaching experience.
Looking forward to your reply,
Matt
