Discussing Contact Sourcing and Waterfall Enrichment Strategies for Scalable Data Quality with Clay Users

Hey Clay community! Yann here, based in Paris 🇫🇷 I co-founded LoneScale 5 years ago. On the Clay side of what we do: contact sourcing + waterfall enrichment for email, phone, and company data. BYO provider keys, no markup on credits. Joined this Slack because I want to learn from operators who actually run Clay at scale. Quick caveat: I’m building a sales data product, so feel free to mute me if vendor presence isn’t your thing. Not here to pitch, here because the Clay crowd has the sharpest takes on data quality I’ve seen. Three things I’m curious about: - Your waterfall setup for email and phone (which providers, what order, when to skip vs retry) - How you decide between Clay native enrichment vs piping in external sources - The weird edge cases you’ve hit on contact sourcing at scale Trade war stories anytime. Happy to geek out on data infrastructure too. 🔗 LinkedIn: https://www.linkedin.com/in/yann-aleman/ Trail running and getting beaten in races by my 5yo outside of work.
