Seeking Advice: Is There a Strong Demand for Presentation Design in Startups? (I will not promote)

Hi! I’ve been a Graphic Designer for over 10 years, but I haven’t had work for the last 2 years. Maybe graphic design is too saturated? I’m thinking of niching down to Presentation/Pitch Deck Design. I have some doubts, so I’m asking for help from you all. I’m not promoting myself—I just want to know if there’s really a strong demand for presentation design in startups. Knowing this will give me the confidence to pursue it, as I also don’t have enough time to switch skills. Kindly help me. Thank you!
