Pay! Expert interviews can be had through expert networks. I know it’s a hustle to get free ones, and worth it, but you could go to GLG, Coleman, ThirdBridge etc and just pay for interviews if you need them done. An interesting alternative is with Arbolus, who lets you write questions and get asynchronous video responses. Research interview sourcing is very hard, and made harder when it is commercially motivated since people are wary of SUGR (selling under the guise of research). The expert networks impose codes of conduct and fees that make the process more costly, but also much more productive.
