The quartermaster for sales handovers

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

When a rep changes, resigns, gets promoted, hands off a territory, the same kind of leak starts, except it is invisible. The relationships, the reason each deal sits where it does, the procurement contact who really decides: none of it is in the CRM, and the rep taking over starts blind.

handedover is the quartermaster for that moment. It runs the handover, scores it, and walks the new rep in.

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.

The cost

Your CRM holds maybe ten percent of what closes a deal. The other ninety walks out the door the day a rep changes seats.

What walks out the door when an account changes hands.

Relationships

Years of trust, in nobody's CRM.

The procurement director she has lunch with. The technical buyer who only answers WhatsApp at night. The introductions that took three years to earn.

Reasons

Why each deal sits where it sits.

The renewal stalled because the customer's GC is on sabbatical. The Stage 3 deal is parked for forecast-smoothing. The CFO got burned by your competitor in 2022.

Patterns

How this customer actually buys.

Which procurement team wants a price list and which wants the narrative. Which buyer is insulted by an early security pack. Which renewal cycle quietly drifted a quarter.

Accenture's Teresa Tung and Philippe Roussiere, writing in the Berkeley Haas California Management Review, call tacit knowledge the next competitive moat. For a sales team, that moat is everything that leaves when a rep does. 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 outgoing person through two structured sessions, account by account. No blank-page homework. A third session triggers automatically if the handover is coming up short.

The trustscore

Quality you can see before they leave.

Every handover gets a trustscore, a shared measure of how complete it is. Open any score and it shows what is strong, what is thin, and what still needs a conversation. The manager knows where each account stands while there is still time to act. Not when a deal quietly goes sideways three months later.

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.

A trustscore per account, so you know where you stand while you can still act, and you can open any score to see what is behind it. The process runs itself instead of being nagged into existence on top of your real job.

The outgoing person

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."

Build your own

Sales is the flagship. The engine runs any handover.

With the custom handover builder, a team lead can build a handover module for their own function, customer success, solutions engineering, services, operations, finance, in a few minutes. It becomes a reusable template for the whole organisation, run the same way every time someone changes seats.

Customer Success · handover module built in 4 minutes
Account health. The real signal, not the dashboard colour: who is quietly disengaged and why.
Renewal risk. What is actually putting this renewal at risk, and who has to be kept warm.
Never cc. The stakeholder who derails every thread; route around them.
Open promises. What was committed verbally that is not written anywhere.

Illustrative. You choose the function, the builder shapes the module.

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, scored answer. 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.

The vision · where this is going

handedover is the first module of something bigger.

handedover is the first product from biowissen. The same approach extends to every kind of handover: onboarding, offboarding, role changes, reorganisations. Each a proper, guided handover for that moment.

And as more handovers run, the knowledge they capture, verified, scored, kept current, accumulates into an organisational memory: a knowledge graph your people, and in time AI agents, can query. That is the destination. Today, the proof is handedover.
