Multichannel prospecting for B2B sales teams
Outreach on autopilot. Messages that never sound like it.
PERSO gets to know every prospect the way you would, writes to them as you, and keeps the conversation going on email and LinkedIn until they reply.
How it works
From cold name to booked meeting.
Find who to write to
The Watchlist spots new people in a role, champions who changed jobs, companies hiring or raising funds, and lookalikes of your customers. Or add people yourself: from your CRM, a Sales Navigator list or a CSV.
PERSO gets to know them
It reads your CRM notes, the emails you already exchanged, their LinkedIn profile and what the web says about them and their company, and finds and checks their email address.
Pick a play
Cadences across email and LinkedIn that react to what happens. Connection accepted? The message goes out. No reply? The follow-up is already planned.
Approve in one click
Every message lands in your queue, written in their language. Edit if you want, approve, and it goes out from your own mailbox or LinkedIn.
Replies are handled
A reply stops the sequence at once, and PERSO drafts your answer for you to approve. Nobody is chased after they answered.
It gets better every week
PERSO learns from every edit you make, so the next message needs fewer.
Templates get ignored. PERSO gets answers.
Hyper-personalised is not a feature we bolted on. It is the name.
Trained on your wins
It learns from thousands of emails your team already sent, and which ones actually got replies. Your voice, your winning angles, at scale.
Written for one person, once
No merge tags, no variant pool. Every message is composed fresh for the one person it goes to, in the language they answer in.
Guardrails that scale with you
Daily limits, rejection cooldowns, company-wide contact ceilings and a suppression list that survives everything. Scale without burning your domain.
Integrations
Plugs into your stack.
Everyone on your team connects their own mailbox and their own LinkedIn. Mail goes out as them, and replies land where they already read them.
Your mailbox
Every email goes out from your own address, and replies land where you already read them.
Profile views, connection requests and messages, on your own account.
Your CRM
PERSO reads what your team already knows. No CRM? It keeps its own record of every prospect, touch and reply.
PipedrivePlannedMeetings
PERSO can end an email on your own booking page, whichever tool it lives on. Nothing to connect: your link, in every message.
Built in, nothing to connect
Other tools sell AI and enrichment as add-ons. PERSO does both for every prospect, before anything is sent. No extra subscription, no AI licence or MCP setup of your own, no list full of dead addresses.
Built in Zürich
A European company for European sales teams. PERSO writes to your prospects in the language they answer in: German, French, Italian, English and more.
Your data stays in Europe
Application and database run in Frankfurt. Nothing is stored outside the EU.
GDPR by design
Opt-outs checked live before every touch. An erasure is honoured everywhere and cannot be re-imported.
Enrichment included
Addresses found and bounce-checked before anything sends. No list imports full of dead mail.
Measurement
No number it cannot stand behind.
A 100% reply rate from two emails is noise, and a tool that prints it will be believed. Every rate in PERSO arrives with the count behind it, and the ones too small to trust show a dash instead of a guess.
Four sends is not a rate. It stays a dash until it means something.
Why I built this.
I sell for a living. Well over a thousand first emails to finance and operations teams, in German, French and English. PERSO is built on the ones that got answered, so it writes the way I do, and it never sends anything I have not read.
