Pilot at −50 %: we are now taking on our first customers
When an expert retires or moves on, their tacit knowledge, everything that was never written down, walks out with them. Tarumo captures it in time: AI interviews the expert briefly and regularly, the expert approves the knowledge cards made from the answers, and from then on any employee gets the answer in the expert's own words.
The bearing is squealing on the rolling line. What do I do?
“Order a new bearing as soon as the squeal starts. Delivery takes ten days, and the failure comes in about a week.”
Maintenance manager, recorded 3 Sep 2026
The problem
Early warning signs on machines, workarounds for exceptions, supplier relationships, the quirks of old systems. It lives in people's heads, and a company usually notices the loss only when something stops.
“The gearbox squeals a week before the bearing fails. You can hear it on frosty mornings.”
“When the main contract falls through, I call a salesperson I know. He delivers in three days.”
“The nightly job crashes at the turn of the month. The fix command is only in my home directory.”
Illustrative examples. Yours will differ, but they are just as unwritten.
How it works
An interview takes the expert about ten minutes at a time. The knowledge is recorded in their own words, and it stays under their control until they approve it.
The Risk radar shows whose knowledge is at risk and when. A manager records the key people and their areas of expertise, and Tarumo works out where to start.
The AI asks like an experienced mentor and follows up on general answers. The expert answers by typing or dictating, and can listen to the questions read aloud. The industry knowledge pack decides what is asked.
The answers become a draft knowledge card. The expert approves, edits or rejects it. Only an approved card is published.
Anyone asks in plain words and gets an answer in the expert's own words, with the source. If there is no answer, Tarumo says so instead of guessing.

Knowledge no AI knows
AI learns from what has been written. General language models know public information, and a company's own AI search only finds what is already in your documents. The warning signs and workarounds of your machines are written nowhere, so the AI can only answer from general knowledge.

Answers from general knowledge: the squeal could come from lubrication, bearings or alignment.

Tarumo does not replace general AI; it gives it what has been written nowhere. The knowledge is recorded from the expert themselves, and answers rest only on cards they have approved, with the source. That is the difference from guessing.

Trust
Nothing is published without their approval. A card that has not been approved does not show up in search or in the AI's answers.
The AI answers only from published cards and tells you whose words the answer comes from and when it was recorded.
We commit to keeping servers, database, backups, AI and speech recognition in the EU. Subprocessors and locations are listed in the data processing agreement.
Each organisation's data is kept separate, down to the database level. Approvals, changes and exports are written to a log.
Tarumo measures the risk of losing expertise. It does not score or compare employees.
Your organisation's administrators and managers cannot see interview answers, only the person interviewed can. They see the published knowledge cards.
When dictation is on, audio is deleted 30 days after transcription by default. An organisation can shorten that or switch audio storage off entirely.
You can export the published knowledge cards at any time as Markdown and JSON files. Outdated information is replaced, not deleted: the version history stays.

FAQ
Tarumo is an online service for companies that captures the tacit knowledge of experts who are retiring or changing jobs. AI interviews the expert briefly and regularly, the expert approves the knowledge cards made from the answers, and any employee then gets the answer in the expert's own words, with its source. Tarumo is developed by Tarumo Oy, a Finnish company.
Tacit knowledge is know-how learned through experience that has never been written down: the early warning signs of machines, workarounds for exceptions, supplier relationships and the quirks of old systems. It is hard to document, because a busy expert does not write it down and does not know what others do not know. That is why it is easily lost when an experienced expert retires or changes jobs. Tarumo captures it by interviewing the expert and turning the answers into knowledge cards that the expert approves.
A wiki holds only what someone has the time and remembers to write, and its content goes out of date. In Tarumo, AI asks the expert questions like an experienced mentor and follows up on general answers, so it also captures knowledge nobody would have thought to ask them to write down. Outdated information is replaced by a corrected version, and the version history stays.
General language models know public information, and a company's own AI search finds only what is already written in its documents. They cannot find knowledge that was never written down, so they can only answer from general knowledge. Tarumo captures the knowledge from the expert, and its AI answers only from knowledge cards the expert has approved and names the source. If there is no answer, Tarumo says so instead of guessing.
In the EU. We commit to keeping servers, database, backups, AI and speech recognition in the EU, and subprocessors and locations are listed in the data processing agreement. Each customer organisation's data is kept separate, down to the database level.
Only the person interviewed. Your organisation's administrators and managers cannot see interview answers. Others see only the knowledge cards the expert has approved for publication: a card that has not been approved does not show up in search or in the AI's answers.
No. Tarumo measures the risk of losing expertise, not how people perform. It does not score or compare employees. The EU AI Act classifies AI used to evaluate or monitor workers' performance, or to make decisions about their employment, as high-risk. Tarumo does none of these. The Risk radar shows the areas of expertise that have only one expert, sorted by departure date.
The price follows the number of key people, and people who only search and ask are always free. The planned packages are Mapping at €4,900 one-off, Standard at €790 / month for up to 15 key people and Extended at €1,900 / month for up to 50 key people. For small companies, Handover costs €1,490 one-off for one departing person. Prices exclude VAT. Our first customers get launch offers: a pilot at 50 % off for up to four months, 33 % off the first year after the pilot and for the first 10 founding customers, and Mapping at €3,000 for the first 10.
Yes. For small companies there is the Handover package: three months of interviews and knowledge cards from one departing person for their successor, plus a year of read access, for €1,490 as a one-off fee excluding VAT. It suits a change of ownership or a family succession, when the know-how of the owner or a key person must pass to whoever continues. No separate mapping is needed.
The pilot takes at most four months: mapping in weeks 1–2, then weekly interviews and finally a summary for management. During the pilot you pay half the chosen package's monthly price and of additional key people, and the pilot mapping costs €1,000. We need a list of key people and their departure dates, and a half-hour interview with the managers during mapping. An expert spends about ten minutes per interview.
Finnish and English. The user interface and interviews work in both languages. The expert answers the interview by typing or dictating.
Yes. You can export the published knowledge cards at any time as Markdown and JSON files. The knowledge is yours: outdated information is replaced, not deleted, so the version history stays.
Pilot
Tarumo is in its pilot phase, and we are now taking on our first customers. The pilot takes at most four months. The aim is that you know whose knowledge is at risk, and the knowledge cards are in use. During the pilot you pay half the chosen package's monthly price and of additional key people, and the pilot mapping costs €1,000.
We need little from you: a list of key people and their departure dates, and a half-hour interview with the managers during mapping. Otherwise the work is done by the experts in their own ten-minute interviews. Pilot terms, including the use of the reference, are agreed in writing.
