Collaborate with freelance community leaders/financial bloggers

InvPilot is a simple invoicing tool for freelancers, aiming to be faster and simpler than existing solutions. The OP explicitly seeks feedback from the indie hacker community. Collaborating with leaders of freelance communities (e.g., Reddit mods of r/freelance, popular freelance bloggers, or financial educators who advise freelancers) could provide invaluable feedback, user acquisition, and endorsement, as the tool directly addresses a pain point for their audience.
