If you are just swamped with feature requests, and not actively trying to grow 100x or more, then no - you do not want capital. Bringing in investors brings in expectations of not just an exit, but a big exit -- they will push you into a high-risk model where you go big or go bust. If you have already been running for 5 years, you don't need that. I don't know the details of why you are swamped, but I suspect you just need to aggressively triage those requests: 1) Figure out which of those requests are need-to-have vs. want to have. This alone will take a bunch of the weight off your shoulders. 2) Figure out what 80% of the people want. Do not go changing your product for a minority, as it will just dilute your PMF and add unneeded complexity. 3) Pick out low-hanging fruit and get them done. Then prioritize the rest. Really, this is where a good product owner will make you thrive. Someone who knows what to do, and what not to do. And someone who will let the team work, not force them into their own favorite dev process. Find that right person whose job it is to figure out and manage that backlog, who can work will with engineers, leaders, and customers... and you should be fine.
