Six specialists.
One negotiation.

Sotto is a negotiation boutique staffed by AI. Its agents write your playbook, prepare each deal, put you through a rehearsal against an opponent who has never seen your notes, whisper advice while you are still in the room, and afterwards tell you what really happened.

Deal preparation Live call support Supplier negotiation Sales calls Strategic partnerships Team rehearsal & cohorts Post-call debrief

The deal is decided before anyone dials in.

Playbook, brief, rehearsal — quietly, weeks earlier, in the preparation nobody has time for. Four of the six agents work here, and this is where the boutique spends most of its time.

Canon

Once, for the whole team canon, the rules held authoritative

Your playbook, and the discipline to follow it

A playbook is how your company negotiates, written down: the order you give concessions in, who may approve what discount, what nobody may ever promise, and the fallback wording for the clauses that always fight.

Canon interviews your team to write it, freezes every published version, and then checks each deal against it. A discount above your approval limit is caught before the call, not after the signature. It works across languages: a French brief is checked correctly against an English playbook.

Prelude

Before each deal prelude, what is played before the piece

It won't let you enter with a vague plan

Every deal gets a workspace, and Prelude interviews you until the brief is real: what winning looks like, your target, what you can trade and in what order, the red lines, and the number where you walk away.

Paste rough notes and it structures them. Upload the contract and it reads it. It already knows what you conceded in the last call with this client, so it asks about the gap instead of asking you to repeat yourself.

Practice

The day before practice, the one room where it does not count

An opponent who has never seen your notes

A rehearsal is twelve minutes on the deal you are actually about to negotiate, against a counterparty invented for the occasion: an opening, a real settle point, a walk-away floor, what is pushing them, and whether the alternatives they wave at you are genuine or a bluff. Drawn fresh every time.

You pick the moment — the price push, the exploding offer, the nibble at the end, hostile silence. You do not pick the difficulty. There is no easy setting. They speak first, mid-conversation, and the round opens at the hard part.

The opponent is never shown your target, your red lines or your walk-away — not as a policy that can drift, but because the code that builds it has no path to those fields. An opponent who can see your floor sets theirs just below it, you close every time, and you learn nothing while feeling excellent.

Then it marks you, not the outcome: six weighted dimensions, the one turn where the thing was decided, and at most three concrete things to do differently — ask what is behind the objection before naming a number, never be more assertive.

Nothing above is visible during the round. It opens when the round ends — and it is the one thing a real negotiation never gives you, no matter how well the call went. The answer key.

Maestro

Throughout, not a stage maestro, reads the full score, hears every part

One client, seen whole

A relationship is not one meeting. Maestro reads across every channel you have with a client: the calls, the contracts, the email threads, the deals you closed two years ago. It holds where things actually stand.

Ask it a strategic question and it answers with the whole file open. What is still unresolved from three meetings ago, which thread contradicts which, where the pressure really sits. Export the answer as a brief your team can act on.

Run your team through one case.

A workshop ends, a kickoff ends; the practice does not have to. Your cohort — your team, or your class — keeps rehearsing the same case against the same counterparty, and you see, per person and per skill, where each of them still needs work. You read the rehearsal rounds the participants agreed to share, for as long as they keep them. Nothing outside that case, and nothing they did not share.

Practice that outlives the room

Everyone in the cohort keeps rehearsing the case you set, against a counterparty that has read the case and nothing of theirs. Rounds are included per participant.

Where each person needs work

A score per skill, never a grade: seven dimensions scored on their own, a group median read from each participant's latest scored round with the count beside it, "not scored" where the judge declined — so you take the right person aside for the right reason.

Their words, your read

The transcript of each rehearsal round a participant shares, with the mandate they were given on top, and the moment that decided it. What Sotto whispered to them stays theirs, and a round they withdraw leaves your view.

Sotto

Live, in the room sotto voce, spoken under the breath

It hears everyone. Only you hear it.

Sotto joins the video call as a silent, honestly named participant. It transcribes every speaker on their own track, follows the negotiation against your brief and your playbook, and sends advice to your side of the table only: a tactic aimed at you, a number that breaks your limits, a red line about to be crossed.

The rest of the time it says nothing at all. That is the hard part, and the point.

Their screen

nothing is sent here
not now, not ever

The counterparty sees an ordinary video call with a clearly named assistant in it. They never see a word of your advice.

The other side cannot receive advice

Everything Sotto sends passes one gate that checks role before every message. There is no broadcast path and no setting to get wrong.

Silent, visible, consented

It publishes no audio or video and never hides. Each participant agrees before it listens to them, enforced when it joins rather than in the interface.

Every speaker, every language

One transcription stream per person, so every line is attributed correctly. Languages are detected sentence by sentence, with nothing to configure.

Ask what you can't say out loud

Type "what's their weak point here?" and get an answer in seconds: to your whole side, or to you alone. You can also pull a private translation of what was just said.

The meeting isn't over when the call is.

Coda

Minutes after the call coda, the passage that closes the piece

What really happened, not what you remember

Coda writes up the call while it is still warm: what was agreed, what each side conceded, the action items and who owns them, attached to the deal rather than to somebody's notebook.

Then the harder read. How the conversation went against the plan you walked in with: which concessions you gave that were never on the list, where a limit quietly moved, which advice you took and which you let pass. Prelude uses it to brief the next call, so the same mistake gets harder to repeat.

An example, drawn: what became of one call's objectives

summary & action items concession ledger plan vs. actual feeds the next brief

Consent: Each participant agrees before Sotto subscribes to their audio.
Audio: Never stored. Buffers are discarded the moment speech becomes text.
Recording: Off unless the host turns it on for that call, and theirs to delete.
Retention: Your operator sets the numbers and the jurisdiction. Nothing is hardcoded to one country's law.

Put the whole desk behind your next deal.

A 30-minute walkthrough on a live call: we write a playbook, prepare a deal, join a room, and you watch the advice arrive on one side of the table only.

A trial starts the same way: tell us what you want to test, and we call you.
