Manifolds is a deanonymization tool built for companies with high signup volume. We work with mature and hypergrowth companies that have anywhere from 1,000 to 1M signups per month. You provide an email, we return rich person and company data to you.

What to expect from an ideal product
- Manifolds runs automatically at signup, no manual research needed, so your sales and ops teams get enriched contact and company data the moment a new user creates an account.
- Works at scale from 1,000 to 1,000,000 monthly signups, so enrichment does not slow down or break as your growth accelerates.
- You send one email address, Manifolds returns verified person and company details, making it a simple API-first workflow that fits into any existing signup stack.
- Knowing who signed up lets you route leads faster, personalize onboarding, and prioritize outreach before a user churns or goes cold.
- Built specifically for companies where anonymous signups are a real business problem, not a side feature bolted onto a broader data platform.
