Every coffee, every email, every text — small steps, big impact.
Investors, design partners, first hires, early customers — the people who get you to Series A live across your inbox, your phone, and your calendar. Quartet keeps every relationship on one thread.
Three things. Done well.
Quartet isn't a 200-feature CRM. It's three capabilities, built for founder-led sales: Cadence tells you who to reach. Omni-channel remembers what was said, on every surface. Look-alike groups turn one good customer into the next ten.
The people you've gone quiet on, every morning.
Set a cadence per relationship — weekly, monthly, quarterly — and Quartet surfaces who's overdue. One short list. One click drafts a thoughtful follow-up using your latest context.
iMessage + Email — one surface.
Two inboxes, one person. Quartet merges Mail and iMessage (plus SMS, LinkedIn) into a single chronological thread per relationship. Reply from the same window — Quartet sends through whichever channel they last used.
Find the next ten like the one who said yes.
Pick a customer who closed, an investor who got it, a recruiter who delivered. Quartet clusters their look-alikes across your network — by company stage, role, mutual context, conversation tone — and queues them up to reach.
An easy Kanban to track deals — like every CRM you've used.
Drag a relationship across stages. The thread, the cadence, the look-alikes — all stay attached. Familiar surface, founder-grade brain.
Founders supported by Quartet—— VS. ——every other CRM.
Every other CRM was built for sales teams of 50, deals of $50k+, and a manager who wants forecast accuracy. Quartet was built for the three of you, in a room, before the round closes.
