Signup/Extraction/Stealth automation using no browser

We have a working python classic selenium scraper. It work as expected, but it's very slow. We tried to reverse the API of the website we create account and extract data, but faced a couple of issues. Website use Akamai. We tried paid services to generate sensors, but then we understood that it also use NuData, and maybe others. We tried to reverse the mobile app and face mostly the same issues. Understand that we have a browser solution that is working. We could scale and have more server, virtual machines, but it seems very heavy when we could just have a request based solution. We dont mind to pay for services that help example solvers, as long we dont miss anything and everything is centralized. We are willing to pay more/long term relationship/even build a Sass together if you are willing to work with us in making an api for solving akamai and nudata. We like rust and python.
