The quartermaster for sales handovers

If a pipe burst in your office,
you would act in minutes.

A deal is won, and the account crosses to people who sat in none of the calls that won it. The same kind of leak starts, except that this one is invisible: what the customer was promised out loud, why they really bought, who actually signed, and the one subject that makes the room go cold. None of it is in the CRM, and unlike somebody resigning it does not happen a handful of times a year. It happens at every win.

handedover is the quartermaster for that moment. It runs the handover as a guided interview with the person who won the deal, marks every field covered, mentioned or missing while there is still someone to ask, and the team taking the account over walks in already knowing.

It runs whenever a won deal moves to people who did not sell it: a new logo, a new business unit or product line inside an existing customer, an expansion large enough to start its own implementation. Where the winning team keeps the account, nothing crosses and there is nothing for handedover to do.

The first handover → Ten working days, three sessions, two documents, one real won account, run with the founder. EUR 2,500 flat, and nothing is introduced at your end. Earliest start mid-October 2026.

Champion
Sarah Chen, VP Eng. Four-year relationship. Replies to WhatsApp after 18:00, not email. Kids the same age as the outgoing rep's.
Who decides
The real signer is J. Okafor in Finance, not the SVP listed on the org chart. Nothing closes without her.
Watch out
CFO was burned by a competitor in 2022. Do not bring up that vendor. The room goes cold instantly.
Renewal
Drifted from Q1 to Q3 after the customer realigned its fiscal year to a German parent. Diary it for August, not March.

Illustrative example of a handedover brief: the kind of context that never reaches the CRM.

Who carries it

A thin handover does not cost everyone the same thing.

VP Sales. The deal is booked and the quarter is closed. What comes back a year later is a renewal that stalls or an expansion that never starts, and nothing in the forecast tells you which of last quarter's wins was handed over thin. The one person who could still answer is already on the next deal.
Head of Customer Success. Your team inherits a customer who already believes things: a date said out loud in a call, a scope implied, an answer within two hours because that is what the sale felt like. You find out what was promised at the moment the customer says it back to you, and what they take from it is that the attention stopped at signature.
Sales Operations. You own the one step that has no instrument. The fields exist and they get filled the way back office always gets filled, the internal kick-off happens when somebody remembers to call it, and two people running the same handover produce two different results. When somebody asks what a bad one costs, there is no number in the house to answer with.
The cost

Your CRM holds maybe ten percent of what won the deal. The other ninety stays with the person who sold it, and that person is already on the next one.

What does not cross when a won account changes hands.

Promises

What the customer already believes.

A date said out loud in a call and written nowhere. A scope implied rather than agreed. The service level nobody put in the contract, which the customer has already repeated to their own team.

People

Who decided, and who lost the argument.

The finance lead who signed reluctantly. The security reviewer who is the real gatekeeper and is on leave until October. What your champion promised their own board in order to release the budget.

Habits

What they got used to while you were selling.

Messages answered at nine in the evening. A reply within two hours rather than two days. The standing call somebody on your side always convened. None of it was agreed, and all of it is now the baseline.

For a sales team, that moat is everything that stays with the person who won the deal. It is the moat.Tung and Roussiere, "Tacit Knowledge Is Your Next Competitive Moat," California Management Review, March 2026.

How it works

Meet the quartermaster.

Nobody has ever enjoyed a handover, and almost no one has had a good one. They are formless, dreaded, and owned by no one. handedover is the quartermaster: it runs the process so no one has to invent it. It does not add another deliverable to anyone's pile. It runs the handover for them.

Two guided sessions

It asks; they answer.

The quartermaster takes the person handing over through two structured sessions, account by account. No blank-page homework. A third session triggers automatically if the handover is coming up short.

Coverage per account

You can see what is thin while you can still ask.

Each account is broken into the fields that matter, and every field is marked covered, mentioned or missing. The manager can see which accounts are thin while the person is still there to answer, instead of finding out three months later when a deal has quietly gone sideways.

Verified by the team

It does not depend on one person.

The manager and adjacent functions, sales engineering, customer success, services, can contribute what they know and verify the work. The handover holds up even when the exit is not cooperative.

Documents folded in

More than what they remember to say.

Relevant documents are uploaded and folded into the handover, so the record is not limited to whatever happened to come up in conversation.

Built for three people

Everyone gets their own view.

A handover touches three people, and each needs something different. handedover gives each of them their own view: tasks, calendar invites, milestones, and a Q&A interface, all where that role already works.

The manager

Visibility, finally.

Coverage per account, covered, mentioned or missing, so you know where each handover stands while you can still act on it. The questions are asked for you and the gaps come back as follow-up questions, so the handover does not have to be nagged into existence on top of your real job.

The person handing over

Forty minutes, not dread.

A guided session instead of a blank-page brain-dump. No homework, no guilt. And a certification that records, for their own portfolio, that they left well.

The incoming person

Walked in, not dropped in.

Their view tells them what to read before which meeting, who to call first, and what not to step on. Not 23 documents and "good luck."

Two moments

Accounts change hands twice as often as you think.

Most people picture a resignation. That is the rarer of the two. The one that runs constantly is a win, when the account leaves the person who sold it and lands with the people who now have to deliver it.

Honest scope

What handedover is not.

Not a CRM. It does not replace Salesforce or HubSpot. It fills the part of them that was always blank.
Not a CRM integration, yet. It does not write back into your CRM today. The handover lives in handedover, in each role's own view. Integrations are on the roadmap.
Not a wiki. Nobody keeps a wiki current. handedover runs once, at the handover, while the knowledge is still in the room.
Not a call recorder. A transcript is raw material. handedover gives the next person a structured answer, with the thin parts marked. Not 40 hours of audio.

Built by Matthias Drebes, who spent nearly his whole career in B2B sales and seven years helping scale Celonis from 100 to 3,000 people in the Process Intelligence category, and watched that knowledge walk out the door every time someone good changed seats.

Direction · not shipped yet

Your definition of a good handover, not ours.

A measure of handover quality only holds if it is the customer's measure. What counts as a properly handed over account differs from one sales organisation to the next, and in most companies the criteria already exist somewhere, written into an onboarding deck or carried in the head of a manager who has done it thirty times. We are building towards criteria a customer can configure, so that what handedover treats as complete is what your organisation calls complete. This is in development and it is not part of what you can use today.

The vision · where this is going

What is worth handing over has to be asked for.

handedover is the first product of biowissen, and for now it is the only one. The usual way to capture what somebody knows is to watch them work: sit on the screen, join the call, read the thread, keep whatever goes past. That collects a great deal of material and not much judgement. handedover works the other way round, the way careful research has always worked, by going to the person whose judgement is actually needed and asking them properly, while the account is still fresh in their head.

What a handover leaves behind is therefore not a pile of recordings. It is the reasoning of the person who won the account: who really decides on the customer side, what that customer now expects, where delivery is most likely to strain. Run that at every win and an organisation slowly holds its own judgement about its own customers, in the words of the people who earned it. The direction stays deliberately narrow: enterprise sales, one moment, the deal that has just been won. Depth in one handover is worth more than a template for all of them.

The second direction is to ask for less of your people's attention, not more. Nobody who takes part in a handover should need an account with us, a password or a rollout. The quartermaster should reach people in Teams, in Slack or by email, where they already work, and hand the result back as something they can read. That is planned and it is not built today, and saying so is cheaper than the alternative, because the last thing a sales organisation needs is another tool to introduce.
