U.S. Custom Software Services Lead Generation

I want to work on a percentage-based partnership model.

I need a fresh, well-researched list of U.S. companies that are actively looking for custom software development services. The focus should be on organizations that have either expressed a current need or are clearly in a buying phase (such as recent funding rounds, open RFPs, technology modernization initiatives, digital transformation projects, expansion plans, or similar indicators).

The objective is to provide ready-to-contact decision-makers so my team can pitch our custom software development services. Web and mobile projects are relevant only if they support a broader custom software requirement.

Deliverables (Acceptance Criteria):
• A spreadsheet (Excel or Google Sheets) with at least 200 qualified U.S.-based leads.
• Required columns: Company Name, Website, Industry, Company Size, Primary Decision-Maker (Name, Title, Email, Direct Phone or LinkedIn), Evidence of Custom Software Need, and Date Verified.
• All email addresses must be verified and free from obvious hard-bounce risks.
• No duplicate entries, resellers, agencies, or freelancers.

Please also include a brief overview of your sourcing methodology, including the tools, databases, platforms, or research process used. However, the lead list itself remains the primary deliverable.

I'm interested in setting this up as a percentage-based collaboration rather than a fixed-fee arrangement.
