Signal-based outbound — live now

The SDR stack
is broken.

Most teams duct-tape Clay + Apollo + Smartlead together, paying $500 per opportunity in tool costs, and still manually driving every email. Ply is the autonomous SDR that closes the full loop — signal detection, research, sequencing, sending, warmup, follow-up, and meeting booked — without a human in the loop.

Signal-based reply rates 14–25% vs. 3.4% cold email average

How it works

Four steps. Fully autonomous.

01

Signal Detection

AI monitors funding rounds, hiring spikes, product launches, and job changes across your ICP. Prioritizes by intent, not just fit.

02

Deep Research

Per prospect: company context, team structure, recent activity, LinkedIn history, tech stack. Personalized in seconds, not hours.

03

Multi-Channel Sequence

Email + LinkedIn + call sequence, dynamically adapted based on engagement signals. No rigid step-by-step builders.

04

Meeting Booked

Replies handled autonomously. Objections surfaced and handled. Meetings booked directly into your calendar. You just show up.

What Ply does

Everything a human SDR does.
24/7. At machine speed.

Signal-Based Targeting

Not a static ICP filter. Active monitoring of funding, hiring, product, and leadership signals across your entire market segment.

Multi-Channel Sequencing

Email, LinkedIn, and call flows that adapt based on real engagement. No more toggling between Outreach and Apollo for basic multichannel.

Deliverability Built-In

Automated warmup, sender rotation, and inbox placement testing. Your emails land in primary — not spam — from day one.

Meeting Booking

Handles reply intent, qualifies, and books meetings directly into your calendar. Edge cases escalate — everything else resolves itself.

Real-Time Adaptation

The sequence changes based on who's engaging. If a CFO opens, the message shifts. If LinkedIn gets traction, that channel ramps up.

Live Analytics

Every signal, every email, every reply, every meeting — tracked end to end. You know exactly what's working, what's not, and where to iterate.

Outbound sales hasn't fundamentally changed in a decade. Sequences got smarter, inboxes got stricter, and AI got bolted on as a writing assistant. But the core loop — research, targeting, outreach, follow-up, qualification, booking — is still manual, fragmented, and expensive.

Ply is built for the team that's done duct-taping point solutions together. The team that wants one system that actually runs. The team that measures output in meetings booked, not sequences built.

No operators. No RevOps engineer. No 6-tool stack.
One autonomous system that books meetings while you sleep.
