Shaina here, I built and scaled both a US and an international team in less than four years of over 65 team members and went through an acquisition and October that was incredibly successful due to our hiring and SOP practices. I started bootstrap just like you.

While I'm unsure what you're selling, if it is service the best bet would be to create a duplicatable process as you're doing the work yourself for your clients. Document these processes meticulously and then hire internationally to do the work for your clients, if possible. International hiring has cost benefits and this means you can scale your operation and focus your time on other elements of the business. The documentation part is key to success in hiring.

If you need guidance on how to get these process started, how to recruit great talent overseas (I highly recommend the Philippines for many reasons), and how to keep a team happy that scales with you then I'd love to hop on a call to discuss.
