I'm the CTO of Pitch, so obvious bias here, but have you tried our product? Would love to know what you miss from Impress when using Pitch.
Your product to me seems to be just another freemium presentation product meant for sales pitches, a target market I'm not a part of. For that reason, your product doesn't really strike me as any more interesting than Figma's offering, even if it is technically superior. Figma's has a considerable edge too, as I already trust their web-based design products.
