The opener
Precision, in motion.
Fewer emails.
More replies. Reputation intact.
The engine
Reach them. Get found by them.
Learn what makes them choose you.
Outbound and AI-visibility have always been the same job: being the trusted choice at the moment of decision. Quarry is the first engine to run both as one loop, with one learning brain in the middle. Each half teaches the other.
- 01
Find who's ready
Buying signals (funding, leadership moves, hiring, intent) surface the accounts in-market right now, not a static list.
- 02
Reach with precision
A researched first touch and in-thread follow-ups, deliverability-first and link-light. You approve every send. Nothing leaks.
- 03
Get found by their AI
The same intelligence shapes how you show up in ChatGPT, Perplexity and Google's AI answers, so you're the cited, credible choice.
- 04
Learn, then compound
The advisor learns what makes buyers reply and pick you, and pushes it back into targeting, copy and visibility. The loop gets sharper every week.
Under the hood
Not one AI. A crew of specialists.
The "AI SDR" tools are one model pretending to do every job. Quarry is a team of 10+ purpose-built agents, each expert at one step, all reporting to one human gate. That division of labour is why the work survives a CISO's scrutiny instead of reading like a bot.
Researcher
Builds the account dossier and the money model: seats, region, projected ACV and win-probability.
Account intelSourcer
Finds the right buyer and reveals a verified email and phone before anything is ever drafted.
EnrichmentCopywriter
Drafts the researched first touch and in-thread follow-ups in your voice, short and link-light.
DraftingReviewer
Hard-gates every draft on deliverability and compliance. Anything that could burn the domain is killed.
GuardrailStrategist
Sequences who to reach, on which channel, and exactly when the signal is hottest.
OrchestrationBandit
Runs the experiments: subjects, angles and timing, keeping what wins from real reply outcomes.
OptimisationAdvisor
Learns across the whole loop and recommends the next move, from targeting to copy to AI-visibility.
Learning brainVoice BDR
Places an agentic follow-up call in a cloned voice when an account is warm enough to warrant it.
VoiceReply Triage
Detects, classifies and routes every reply, so interested buyers never sit in an unread inbox.
InboxVisibility
Shapes how you show up inside ChatGPT, Perplexity and Google's AI answers when buyers research back.
AEO / GEOYou, the gate
Every agent reports to one human checkpoint. The crew does the 80%; nothing leaves the building without your call. That is the architecture, not a setting.
Maker-checkerYour stack
Plugs into the tools you already run.
Quarry is the brain, not another silo. It works your mailbox, your data and your channels with your own keys, and writes the outcomes back to the CRM your team lives in. Bring what you have; nothing gets re-platformed.
Email & messaging
Sends and watches replies from your real mailbox, in-thread, deliverability-first.
CRM & pipeline
Syncs accounts, contacts and reply outcomes back to where your revenue team works.
Enrichment & intel
Verified contact data and live web research feed targeting before a word is written.
Bring your own keys. Each channel connects with your credentials and your sending domain, so the data and the reputation stay yours.
See it work
Name a company. Watch it lock on.
The engine in miniature. Type a target and Quarry reads the signal that puts them in-market, the angle it would open with, and how you show up when their team asks an AI about you.

The difference
The spray playbook is over. Here's the other way.
Autonomous "AI SDRs" optimise for send volume. Quarry optimises for replies you can take to a forecast, and a domain that still lands in the inbox next quarter.
Spray-and-pray AI SDR
- Blasts thousands, prays for one percent
- Fully autonomous, and your domain pays for it
- One model faking every step of the job
- Email blast, then silence
- Burned domain, ignored inbox, brand at risk
Quarry
- Reaches the few accounts that are in-market right now
- Human-gated and deliverability-first by design
- 10+ specialist agents, each expert at one step
- Email, voice and WhatsApp, plus found in AI answers
- Replies, meetings, and a reputation that compounds
Why us
Built for the buyers who punish
spam the hardest.
Human-gated by design
Not a "copilot mode" bolted onto a spray machine. The gate-to-send is the architecture. Autonomy does the 80%; you make every call that leaves the building.
Deliverability-first
Low-volume, high-signal, in-thread, verified-before-send. The engine refuses to do the things that burn your domain, because it's measured on replies, never on send count.
Compliance built in
Audit logs, AI-disclosure, one-click unsubscribe, opt-out honoring, EU AI Act and GDPR ready. Trust isn't a feature here; it's the foundation.
Made by people who sell to CISOs. We can't afford to look like spam, so neither can you.
Questions
Straight answers.
What is the AI-era demand engine?
One system that creates pipeline in a world where AI mediates the buyer journey: it reaches the right accounts with precision, and shapes how you appear when buyers (and their AI tools) research you back. Quarry runs that whole loop with one learning brain.
How is Quarry different from an AI SDR like 11x or Artisan?
Those were built to spray volume autonomously, which collapses deliverability and brand. Quarry is the opposite: human-gated, deliverability-first, and targeted by real buying signals. Nothing sends without your approval.
How many agents does Quarry run?
More than ten purpose-built agents, not one model doing every job: Scout finds in-market accounts, Researcher builds the dossier and ACV, Sourcer verifies contacts, Copywriter drafts, Reviewer guards deliverability, Strategist sequences, Bandit optimises, Advisor learns, Voice BDR calls, Reply Triage routes replies, and Visibility shapes your AI-answer presence. Every one of them reports to a single human gate.
Does Quarry integrate with my CRM and tools?
Yes. Quarry plugs into the stack you already run with your own keys: Gmail and Outlook, Twilio and WhatsApp, enrichment via SignalHire, Lusha and Apify, and it writes accounts, contacts and reply outcomes back to Salesforce, HubSpot or Pipedrive. Your data and sending reputation stay yours.
Does Quarry send automatically?
No. Every send passes a human gate. Quarry drafts, researches, follows up in-thread and recommends. You approve each send. Autonomy compounds your judgment; it doesn't replace it.
How does Quarry protect deliverability?
Low-volume, high-signal sending; clean in-thread follow-ups that keep the same subject and conversation; verified contacts before sending; and built-in compliance. The engine simply won't spray.
What is AEO, GEO and AIO?
The disciplines of being cited inside AI answers: ChatGPT, Perplexity, Google's AI Overviews. Quarry treats your visibility to AI as part of the same demand loop as your outbound, not a separate tool.
Precision is invitation-only.
We're onboarding a small number of teams who'd rather send a hundred right emails than ten thousand wrong ones. If that's you, let's talk.
No spam, obviously.
