Inbox management tool for founders
Every deal, investor, and hire lives in a different inbox. Cold brings them together.
As a founder, your inbox is your job. Investor updates in Gmail. Intro requests on LinkedIn. Candidates on WhatsApp. Partners on Slack. The conversation that matters is always in the app you're not looking at.
Cold unifies every channel into a single inbox — and remembers the context behind every conversation. Who introduced you. When you last spoke. What you said you'd follow up on. What the relationship is worth.
Most inbox tools help you process faster. Cold helps you never drop the wrong conversation.
What founders use Cold for:
Tracking investor conversations from first outreach to close
Managing warm intros without losing the thread
Following up on hiring conversations across LinkedIn and email
Keeping partner and BD relationships alive between meetings
Walking into every call with a briefing on who you're talking to
How it works:
Cold connects to Gmail, LinkedIn, WhatsApp, and Slack. Every conversation is unified into one inbox, tagged by relationship, and scored by recency and strength. When a relationship starts to go cold, Cold tells you. When you have a meeting tomorrow, Cold briefs you on the contact the night before.
No manual logging. No CRM to update. No conversations left behind.
Frequently Asked Questions
Does Cold work with Gmail? Yes. Cold connects natively to Gmail and unifies it with LinkedIn, WhatsApp, and Slack.
Is Cold a CRM? No. Cold is a relationship layer that sits across your inboxes. If you use Attio, HubSpot, or Salesforce, Cold syncs to it automatically.
Does Cold work for solo founders? Yes. Cold is built for founders managing high-value relationships across multiple channels without a full GTM team behind them.
What makes Cold different from Superhuman? Superhuman makes email faster. Cold makes relationships stickier — across every channel you use, not just email.
