How long did it take to sell your startup, and what was the multiple on revenue or profit?

I’m curious to hear from founders who have successfully sold their startups. How long did it take from starting your business to completing the sale? And when you sold, what kind of multiple did you achieve based on revenue or profit? Additionally, were there specific factors that helped you maximize the valuation? For example, was it recurring revenue, customer growth, or something else entirely? I’d love to learn more about your experiences—both the challenges and any advice you’d share with founders considering an exit. Also is it possible to launch startup and sell it after 1 year?
