Thus I vibe coded our pitch deck too. The deck is very rudimentary and won't use it for investors etc. It is merely our website in pitch format.
Nevertheless, liked the approach for a few reasons:
The alternatives are still subpar: Gamma is easy to use, but limits you with design options, PowerPoint is hard to use collaboratively & Google Slides feels like a tool that isn't good at neither design (Canva) nor efficiency (PowerPoint). I like Canva as it provides decent design flexibility (template etc.) and is easy to use as a team. However, for non-designer it still can be trick. Lovable did a pretty good job here.
What also is cool; you can prompt a mini-demo of your app into the deck. Henri Sipilä (https://www.linkedin.com/in/henrisipila/) did that and apparently got 300+ leads through it.
The experiment also showed me that the Vibe Coding space is still evolving. Vibe Coding fully fledge web apps might not be the ideal use case for Lovable, but vibe coding pitch decks or mockups might (I use it all the time for mockups).
