THE MARKET IS BROKEN

You were promised an AI SDR. You got a glorified mail merge.

Most "AI SDR" tools charge $800–$2k/month and still require you to write every email, research every lead, and manually follow up. They're automation wrappers, not autonomous agents. You're paying for the label.

RepStack was built for the 2-5 person team that can't afford a full SDR function but needs one: high-volume outbound that compounds, learns, and books meetings while you sleep.

WHAT REPLACEMENT LOOKS LIKE

</>

Prospect Research

The agent pulls real context on every lead — company news, funding, hiring signals, tech stack. Not merge fields. Real homework.

Hyper-Personalized Emails

Every message references something real about the recipient. The AI writes it, sends it, and learns from every reply rate shift.

Multi-Channel Cadences

Email is primary. LinkedIn touchpoints, SMS follow-ups, and warmup are built in. The agent manages the entire sequence and adapts timing automatically.

Reply Handling

Stop manually checking your inbox. RepStack reads responses, handles objections, re-engages cold leads, and qualifies them — then routes hot prospects to your calendar.

Signal Learning

Reply rates drop? The agent spots the pattern, adjusts timing and tone, and restarts the sequence. You get smarter outreach, not more volume.

CRM + Calendar Sync

HubSpot, Salesforce, or anything with an API. Every touch logs automatically. Hot leads get booked. Your CRM stays clean.

HOW IT WORKS

From zero to pipeline in three steps.

Define your ICP

Tell RepStack who you sell to — industry, company size, signals that matter. The agent builds a targeting model from your description, not a spreadsheet.

Launch your campaign

RepStack researches your prospect list, writes personalized emails for every contact, sets up your cadence, and starts sending. All in one session.

Watch qualified meetings roll in

RepStack handles every reply, adapts the sequence, and books qualified meetings on your calendar. You close. That's the whole job now.

THE NUMBERS

24/7 Never stops working. Never calls in sick. Never burns out.

$0 No salary. No recruiting. No onboarding. No benefits. Just pipeline.

6-9% Average reply rate on optimized sequences. Industry avg is 1-3%.

10x More meetings per week than a human SDR — at a fraction of the cost.

WE'VE HEARD THE OBJECTIONS

"Will my emails sound like AI spam?"

RepStack writes each email using real context about the recipient — their company's recent news, hiring patterns, funding rounds. That's not spam. That's the most personalized cold outreach your prospects have ever received.

"What if it says something wrong?"

You approve every campaign before it launches. Human-in-the-loop mode means you see what goes out. Once it's dialed in, flip to full autopilot and let the agent run.

"What about my email reputation?"

RepStack manages warmup, domain rotation, and sending limits automatically. Deliverability isn't an afterthought — it's built into every campaign from day one.

"How long until I see real meetings?"

First campaigns launch same day. First replies typically come within 48-72 hours. First qualified meetings in the first week. Outbound compounds — the longer it runs, the smarter it gets.

Stop paying for a tool. Start paying for a machine.

RepStack costs a fraction of what you're paying now. It researches every lead, writes every email, manages every cadence, handles every reply, and books qualified meetings.

Your only move: set the ICP and let it run.
