A note before we start: Clay rebranded to Mesh (me.sh) in 2025. The product — AI-powered automatic contact enrichment — is the same. If you've been using or researching Clay, you're now looking at Mesh. For clarity, this post uses both names.
Clay/Mesh and RareFriend are two of the more ambitious tools in the personal network space. Both use AI. Both are trying to solve the same problem — your professional relationships are more valuable than you're currently getting out of them. But they approach the problem from opposite ends.
Mesh is about knowing everything about the people you already know. RareFriend is about remembering the people you've met and finding the people you haven't met yet.
How Clay (Mesh) Works
Mesh's core premise is radical passivity: your contacts should stay current without you doing anything. When someone changes jobs, Mesh updates their record. When someone gets mentioned in the news, it surfaces in your feed. When someone you haven't talked to in a while has a life event, Mesh reminds you to reach out.
The automatic enrichment is genuinely impressive. Mesh aggregates contact data across platforms — LinkedIn, email, social media — and keeps records updated automatically. For someone managing a large network of professional contacts, this solves a real problem: the contact database that's perpetually out of date.
The AI layer allows intelligent search. "Who do I know at OpenAI?" or "Who have I worked with in climate tech?" — Mesh can answer these because it's indexed everything it knows about your contacts.
Where Mesh/Clay stands out:
- Automatic enrichment — contacts stay current without manual updates
- Aggregates across many platforms (LinkedIn, Facebook, Instagram, email, and more)
- Intelligent search across your full contact graph
- Handles very large networks elegantly
- Desktop apps for macOS and Windows
Where Mesh/Clay has real limitations:
- No Android app — iOS and desktop only
- No WhatsApp integration despite listing it among integrations (the connection is limited)
- No network expansion — Mesh helps you know more about who you know, but doesn't connect you with new people
- Free tier limited to 1,000 contacts; steeper pricing at scale
- Learning curve — the interface is powerful but takes configuration
How RareFriend Works
RareFriend starts from a different assumption: the problem isn't that your contacts are outdated — it's that you're not capturing the right information in the first place, and you can't find the right person when they become relevant.
Hops, the AI in WhatsApp, captures context the way a conversation works. After meeting someone, you describe them — "just met Vikram, he's building an EdTech tool for Tier 2 cities, introduced through Aisha, he mentioned he's looking for a distribution partner." Hops stores this. Three months later, you ask who you know in EdTech or distribution, and Vikram's context surfaces — including the specific detail that would make a follow-up feel warm rather than out-of-nowhere.
The second layer is the part Mesh doesn't have: matching. RareFriend connects you with new people from the broader network — members whose interests, goals, and professional context align with yours. Your network grows through warm, interest-based introductions, not cold outreach.
Where RareFriend stands out:
- WhatsApp-native — no new app, no new habit
- Context capture is conversational — you describe people the way you'd describe them to a friend
- Network matching — meet new people, not just manage existing ones
- Natural language retrieval — find contacts by description, not by name
- Free for first 1,000 members
Where RareFriend has real limitations:
- Less automated than Mesh — you provide context through voice notes and messages; Mesh aggregates it from platforms automatically
- No automatic enrichment — if someone changes jobs, you'd need to update Hops
- WhatsApp-centric design means the experience is built around that channel
- Newer product, smaller existing network (though the matching gets more powerful as it grows)

Frequently Asked Questions
Did Clay become Mesh?
Yes. Clay (clay.earth) rebranded to Mesh (me.sh) in 2025. The product — AI-powered automatic contact enrichment — remained the same. The new name reflects the idea of a "mesh" of relationships rather than the clay-as-moldable-material metaphor of the original brand.
