Show HN: Persist – an AI agent that follows up accrued channels till they reply
Persist is an AI sales agent for cold outreach that leverages a built-in contact graph of 200M+ LinkedIn profiles, X graph, and verified emails. Users describe their ideal customer in plain English, and the agent automatically finds, enriches, and reaches out via multi-channel sequences (email, text, LinkedIn, X) with smart cadence, stopping when the prospect replies. It offers personalization, unified inbox, CRM integration, and send approval controls.

How it works
From one sentence to booked meetings.
No campaign builders to wrestle with. You talk, the agent works.
01
Describe who to reach
"Founders who raised this quarter." "Buyers looking in 94110 under $1M." Plain English — that's the whole interface.
02
The agent finds & writes
It pulls matches from 200M+ contacts, enriches their details, and drafts a personalized message for every single person.
03
It follows up & books
Multi-channel sequences with smart timing. It handles replies, pauses on a response, and books meetings to your calendar.
The name is the product
It persists until they reply.
Personalized messages on a cadence you set — 1 day, 3 days, 7 days, or your own — switching channels to stay fresh. The moment they respond, it stops.
Day 0
Personalized opener referencing what they care about.
Day 1
Text
A short nudge — only if they haven't replied.
Day 3
A new angle — proof, a case study, or an option.
Day 7
A different channel keeps you top of mind.
They reply
Reply-stop
Persist stops the moment they respond.
You set the rhythm. Any interval, any channel order — or let the agent decide.
Stops on reply Respects opt-outs Approve before send
One agent · every channel
Meet prospects where they actually reply.
Email opener, LinkedIn warm-up, a direct text, a DM on X — orchestrated as one sequence, paced to stay deliverable.
Warmed mailboxes, personalized at scale, with open and reply tracking.
Text
The highest-response channel, used sparingly for the direct ask.
Connect and warm up before the pitch — build familiarity that converts.
X
Follow and DM people based on what they post — reach them while it's relevant.

A full SDR team in one chat box.

Smart, configurable cadence
1-day, 3-day, 7-day — branch on opens and replies. Or just let the agent decide.
Unified inbox
Every reply across every channel in one place — the agent drafts your response and stops the sequence.
Pipeline that compounds
See replies, meetings, and attributed pipeline by channel — and what the agent should double down on.
Bring or build your list
Sync a CRM, drop a messy spreadsheet, or let the agent prospect net-new. All roads lead to outreach.
