List Builder — Verified UK MSP Decision-Maker Lists

I run a Microsoft consultancy (Azure, Power Platform, Copilot, Dynamics 365) and need clean, verified, deduplicated lists of UK Managed Service Providers (MSPs) and their decision-makers for partner outreach. Target companies: UK-based MSPs / IT support firms, roughly 15–200 employees, that advertise Microsoft 365 and/or Azure on their site. For each, note whether they also offer Dynamics 365 or Power Platform. Per company, find 1–2 decision-makers — Owner/MD/CEO at smaller firms; Technical Director/CTO/Head of Professional Services/Head of Projects at larger ones. Columns required: company, website, company LinkedIn, location, employee count, Microsoft partner status (if found), Dynamics/Power Platform offered (Yes/No), contact full name, job title, contact LinkedIn, verified work email, email verification status. Non-negotiable quality rules: named people only (no info@/sales@/support@); every email verified with a tool (NeverBounce, ZeroBounce, or Hunter) with bounce rate under 5%; 100% deduplicated; UK companies only. Deliver as a Google Sheet or .xlsx. Start with a paid 50-lead test. If quality holds, ongoing batches of 300+.
