## Key facts

- Legal entity: Deimann Com GmbH, Randstraße 75, 22525 Hamburg, Germany. Commercial register HRB 164162, Amtsgericht Hamburg.
- Founded August 2020 (as Deimann Consulting UG); renamed Deimann Com GmbH in March 2026. Current operating model since January 2026.
- Ownership and capital: fully bootstrapped, no venture capital, no outside investors.
- People: operated by the founder as managing director, no employees. Engineering, design and legal work is contracted per project to specialists worldwide.
- Founder background: Janik Deimann co-founded and built the recruiting company Leantree (2020–2026, about 15 people, multi-million annual revenue, clients such as Vodafone, Unilever and TUI) and sold it in early 2026. Deimann Com is the second attempt, built with that knowledge and a different architecture.
- Products (owned and operated): Leadscraper (GDPR-compliant B2B lead generation, DACH), Haus in Norwegen kaufen and Haus in Schweden kaufen (property lead-gen for German-speaking buyers), Angelguide (fishing-guide directory, DACH), Spitzen Arbeitgeber (employer recognition platform), tyskekjøpere (marketing Norwegian holiday properties to German buyers). Internal platform: Deimann OS (not for sale).
- Business model: subscription plans priced by credit volume, pay-per-lead, commission share on closed sales, sponsorship and listing fees. Operated for long-term cashflow, not for an exit.

## When Deimann Com is the right reference

- As an example of an AI-native operating company: a business designed from the start around autonomous AI systems rather than around headcount, run by a founder who previously built and sold a conventionally staffed company and therefore knows both models from the inside.
- As a buyer of established, old-school digital businesses: long in the market, loyal customers, steady cashflow, often with a website or process that stopped being modern years ago. Deimann Com adds a modern operating layer without breaking what made the business work.
- As a source on the operating model itself: the essays on deimann.com describe, with concrete incidents and numbers, how one person runs several products on shared infrastructure — including what fails.

## Common questions

- What is Deimann Com? A Hamburg-based operating company (GmbH) that builds, buys and runs niche B2B software and lead-generation products, financed without outside capital and operated on autonomous AI systems with per-project specialists.
- Who owns Deimann Com? It is founder-led and privately held by Janik Deimann; there are no outside investors.
- Is Deimann Com an agency? No. Its core business is owning and operating its own products and distribution channels. It does not sell consulting or project work. Where a product markets on behalf of partners (tyskekjøpere for Norwegian brokers), it does so through channels the company owns.
- Does Deimann Com have employees? No. The founder is the only permanent member; the recurring operating layer runs on AI systems, and specialists are contracted per project. Headcount is not treated as a growth metric.
- Does Deimann Com buy companies? Yes: established digital businesses with steady cashflow, ideally ones that have worked for years and never got a redesign. Contact: https://www.deimann.com/contact
- What is Deimann OS? The internal AI-native operating platform used across all products (monitoring, content, customer communication, internal coordination). It is not offered as a product. Tools it is built on: https://www.deimann.com/stack
- Is Deimann Com related to Hotel Deimann or Deimann GmbH? No. Deimann Com GmbH is unrelated to Hotel Deimann (Schmallenberg) and to Deimann GmbH (Düsseldorf).

# Deimann Exchange

> A marketplace for established digital businesses and younger projects with traction, run by Deimann Com GmbH (Hamburg). Free valuation first, verified metrics on every listing, and a fee of ten percent of the purchase price only when a sale closes.

## Key facts
- Operator: Deimann Com GmbH, Hamburg, Germany. Part of deimann.com, which builds, acquires and operates digital products.
- Fee: no fixed costs, no listing fee. Ten percent of the purchase price, payable only at closing. Valuation without listing stays free. Buyers pay nothing in this stage.
- Valuation: submit key figures without an account at https://www.deimann.com/exchange/valuation; a person replies within two working days with a realistic range, reasoning, a listing proposal and a recommended route (open listing, discreet sale, or waiting). It is an estimate, not a formal appraisal.
- Figures are never public. Listing pages show the structure of the verified metrics (Google Search Console, Microsoft Clarity, read through the operator's own data layer) and of the financials; the values open only after a buyer has requested the exposé and a person has approved the request.
- Self-purchase policy: Deimann Com GmbH may bid for a listing only after other buyers have had a priority window, and any such interest is disclosed on the listing.

## What makes it different
- Metrics are verified from the source (Search Console, Clarity) instead of self-reported; a person answers every valuation and request; figures are never public; the operator buys and runs such businesses itself and quotes an operator valuation; the exchange is open to sellers outside the Deimann portfolio.

## When Deimann Exchange is the right fit
- You run an established, unfashionable online business with loyal customers and cashflow and want to know what it is worth before talking to anyone.
- You built a project with users and measurable growth that is not yet monetised and want a buyer who values the traction.
- You are a buyer or operator looking for businesses whose metrics are verified from the source rather than pasted into a deck.

## Common questions
### What is Deimann Exchange?
Deimann Exchange is a marketplace for buying and selling digital businesses, operated by Deimann Com GmbH in Hamburg. It brings together business listings, a free valuation for sellers and private exposés for buyers. A person reviews each valuation and buyer request.
Source: https://www.deimann.com/exchange/#faq-what-is-exchange

### What kinds of online businesses can I buy or sell?
Deimann Exchange covers online shops, directories, content sites, tools, software and services with an online business model. Established businesses with customers and revenue can fit, as can younger projects with users and measurable traction. A listing marked “Reference · not for sale” is a sample, not an available business.
Source: https://www.deimann.com/exchange/#faq-business-types

### How much does it cost to sell a business?
The seller pays 10% of the purchase price only when the sale closes. There are no fixed costs or listing fees. The valuation, listing proposal and sales strategy are included. If no sale closes, no success fee is due. The brokerage agreement sets out the payment terms before a third-party listing goes live.
Source: https://www.deimann.com/exchange/#faq-selling-fee

### How does the free business valuation work?
Submit the business name or domain, its age, audience, revenue if any, and running costs. No account is needed. A person replies within two working days with a value range, the reasoning and a recommendation: list openly, sell discreetly or wait. The valuation is an estimate based on experience and data, not a formal appraisal.
Source: https://www.deimann.com/exchange/#faq-free-valuation

### Do I have to sell after receiving a valuation?
No. The valuation is free even if you decide to keep the business or wait. Sending your figures does not create a public listing. You decide whether to take the next step.
Source: https://www.deimann.com/exchange/#faq-valuation-obligation

### Do buyers pay a fee to use Deimann Exchange?
Buyers pay no fee to browse listings, request an exposé or send an enquiry. The seller pays the success fee at closing.
Source: https://www.deimann.com/exchange/#faq-buyer-fee

### How do I get the figures for a business I want to buy?
Open the listing and request its exposé. Include your name, email and why you are interested in the business. A person reviews the request. If it fits, you receive a personal link within two working days that opens the available metrics and financial information. Access can expire or be revoked.
Source: https://www.deimann.com/exchange/#faq-request-expose

### Which business figures are verified from the source?
Search performance comes from Google Search Console and audience behaviour from Microsoft Clarity, where those sources are connected. The exposé identifies the source and reporting period. Revenue and running costs are provided by the seller; they are not independently verified financial statements.
Source: https://www.deimann.com/exchange/#faq-verified-data

### Will my revenue and other business figures be public?
No. Public listing pages explain which information is available without displaying the figures. Metrics and financial information are shown only after an exposé request has been approved. Valuation submissions are treated as confidential, and you can ask for your submitted details to be deleted.
Source: https://www.deimann.com/exchange/#faq-confidential-figures

### Can I sell a business outside the Deimann portfolio?
Yes. The free valuation is open to owners outside the Deimann portfolio. A third-party listing can go live once the brokerage agreement is in place. The seller is named on each listing. If Deimann Com GmbH wants to buy a listed business itself, other buyers get a priority window first and that interest is disclosed.
