There is no universal best PSP in the adult or adult AI industry. The approvals are always dependent on the risk guideline and risk appetite of the acquiring bank, and never on the brand names. The same high-risk PSP can say yes to one adult industry sector and say no to another one.
The most critical matter that one should be careful about is knowing how the business is structured, the content rules, the moderation, the web compliance, like age verification, subscription versus one-off mix, and finally, how to throttle the growth. Remember, most failures happen after approvals, not before
The winning approach will be to align the model with current underwriting principles and choose a higher-risk PSP that has massive experience in adult sectors like streaming, toys, AI, and dating, and then, when you get a yes from the PSP, then grow as per the rules.
