Stop expecting someone else to notice and start making things happen. You could just leave and go somewhere else, but the problem will probably follow you unless you luck out and find a great company. Most companies are happy to let their devs stagnate on low pay. Making things happen yourself is the best way to improve your life. Go to the founders of the startup and tell them you want to hire a couple more developers so you can lead, mentor, and improve. Sell them on the idea that you'll be able to move faster and reduce the bus factor of the app you build. Ask for a raise. Suggest features you'd like to build that will improve your learning.
