I'm the cofounder of Eureka Surveys. We're bootstrapped, profitable, and just crossed 1M+ users. We've had an amazing experience hiring customer support in the Philippines. I have a thread about it on Twitter: https://twitter.com/t0mstah/status/1356296043009253382
The tl;dr is that you can hire cheap ($3.50/hr), high quality virtual assistants from the Philippines to handle customer support for you, all from day one. Having CS has really made a difference for us in our business and is one of our main differentiators as we've scaled up the CS team. DM me on Twitter and I can connect you to some excellent VAs looking for jobs!
