Could you build this?

Partial The CSV upload/export UI and LLM synthesis are easily vibe-coded, but dependable email finding and business data enrichment rely on paid, complex third-party B2B data vendors and validation engines.

What it would actually take: The app needs a workflow orchestrator (Inngest, Temporal) that takes CSV records, searches company websites, executes real-time MX record lookups, and probes SMTP mailboxes without getting blacklisted, or waterfalls across APIs like Clearbit, Hunter, and Apollo. The hard part is high-deliverability email verification algorithms, rate-limiting outbound SMTP checks, and managing B2B enrichment costs at scale.
