Focus on those with skin in the game already for that stack/part of the stack. As an example, while at Amplitude our partner Feld M in EMEA created the Adobe Launch Integration (https://amplitude.com/blog/amplitude-adobe-extension). When a SP creates an integration like this, they garner extra credibility in the field. Large SI's do this frequently as well to differentiate their services around Large Technology partners, be it cloud/cloud management, Salesforce, Adobe, SAP and others. If you are a smaller startup, Regional SP's or Agencies may be the right fit to approach.
