How do you tackle strategic challenges in your startup?

Hi everyone, I'm building a platform called Moonlight (https://Moonlights.work) that connects businesses with seasoned experts for strategic insights on a part-time flat-fee basis. Think intro.co but for collaborative work packaged up as a one-time or recurring fee. I'm curious to know if a service like this would resolve some of your challenges. What kind of expert guidance do you believe would benefit your business most?

Some prospective offerings:

• Conversion rate optimization on checkout
• UX design audits
• CRM Marketing strategy
• User research
• Feature Ideation
• Growth strategies
• Leadership coaching/mentoring

Any feedback is more than appreciated :)
