Drop an Excel file, get B2B leads enriched — no APIs or dev work

Many B2B sellers—SDRs, RevOps teams, channel partners and SMB founders—still operate in Excel or Google Sheets and spend hours manually copying, cleaning and chasing data because enrichment vendors are built around APIs, integrations or full CRMs. This creates a bottleneck for teams that need hundreds to thousands of leads enriched quickly without engineering time or procurement cycles. Build a drop-a-file web service that enriches rows from CSV/XLSX with firmographics, technographics and contact data using AI-driven entity resolution and fuzzy matching, then returns a cleaned file and offers one-click pushes to Salesforce, HubSpot or Zapier/Make. The experience should require zero dev work, auto-map columns, surface confidence scores, support batch credits/refunds, and use simple row-based pricing or a low-touch subscription so nontechnical buyers can see value in minutes. This is an attractive moment: a $10.0B addressable market (about 2.5M potential B2B customers at roughly $4K ACV) and converging trends—spreadsheet-first workflows, no-code automation and improved AI entity resolution—that lower adoption friction and increase willingness to buy single-purpose tools. Investors and buyers favor products that remove engineering dependencies and demonstrate fast time-to-value, which is why a focused enrichment drop-in can outcompete platform incumbents for many use cases. To stand out you need three capabilities: superior accuracy on messy inputs via NER plus human-in-the-loop validation, a frictionless UX around file handling and confidence scoring, and enterprise-grade controls (SSO, data retention, compliance) to win larger deals. Key challenges are medium competitive intensity, the cost and licensing complexity of enrichment data, and proving sustained ROI versus embedded CRM enrichments—so initial GTM should target segments with low integration tolerance and easy-to-measure time-saved metrics.
