**The product.** Software for German dental practices. The dentist speaks during or after a treatment, on a phone, tablet, PC or Apple Watch. Dentero writes a structured patient record that is stored with a time stamp, and it proposes the billing codes from the German fee schedules BEMA, GOZ and GOÄ, with the multiplier and the written reason for each code. A billing assistant in the practice checks the codes and releases them into the practice software. The pricing page lists two plans: €149 a month per practitioner for documentation only, and €229 a month per practitioner with the billing suggestions.

**Why it worked.** German dental billing has three fee schedules and a rule that a fee above 2.3 times its base value needs a written reason, so a practice that documents a treatment badly loses fees, the company says, and cannot answer later questions about a bill. Dentero was built by a CEO who, the site says, grew up with dental billing and has seen more than 1,000 practices from the inside, with a long-time billing expert as advisor. It sits on top of the practice software that practices already have, instead of replacing it.

Evidence grades: A = disclosed by a public company, a filing or a payment processor, or verified by one; B = two or more independent reports agree, or a journalist confirmed it; C = a founder claim that no one else verified; D = reported, not verified: one founder claim or a third-party estimate with no second source; E = no revenue figure found, so the headline is a non-money fact and the other facts carry their own grades; calc = computed on this page from graded facts.

## Summary

Dentero is software for dental practices in Germany. The dentist speaks a short account of the treatment, or lets the app record the whole conversation, and Dentero turns it into a Karteikarte, the patient record card of a German practice. It then proposes the codes for the bill from BEMA, the list of dental services that the statutory health insurers pay, from GOZ, the official fee schedule for private dental treatment, and from GOÄ, the fee schedule for doctors' services that dentists also use. For each private fee it proposes a Steigerungsfaktor, the multiplier of the base fee; the home page notes that above 2.3 times a written reason must be stored, and Dentero writes that reason too.

Patrick Steingraf and Volker Tietz founded Dentero Healthtech GmbH in Frankfurt am Main in February 2025. In May 2025 the Hessen state investment company BMH said that it had put a "high six-figure" amount into a pre-seed round, with several business angels, and that Dentero had already won a high two-digit number of customers, among them a dental clinic with 15 locations. In November 2026 the home page says that more than 200 practices use it, and the pricing page lists €149 and €229 a month per practitioner.

No revenue figure was found, so this is a grade E story: every count on this page comes from the company or its investor. The page also shows earlier companies that tried to remove paperwork from health care and failed.

## Pricing

Dentero prices on 7 November 2026, read from the company's pricing page (grade C). The page gives euros per practitioner without the 19% VAT; US dollars at the Federal Reserve H.10 rate of 30 October 2026, US$1.1163 per euro

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| PREMIUM | 149.70 | 166.33 | €134.10 / €149 a month per practitioner; documentation, no billing suggestions |
| EXCLUSIVE | 230.07 | 255.63 | €206.10 / €229 a month per practitioner; adds BEMA, GOZ and GOÄ billing suggestions |
| Onboarding package | 836.11 one-time |  | €749 one-time; 5 hours with billing experts; optional |

The price is per practitioner who uses Dentero, and every plan can be cancelled monthly. Yearly billing takes 10% off, and the FAQ says that a yearly plan comes with a free conference microphone. Every plan starts with a 14-day free trial. The optional onboarding package adds two calls with billing experts from the partner firm RM Dental Impuls. The pricing page lists a chatbot and chairside billing as coming from October 2026.

## How much revenue does Dentero make? The numbers, graded

A pre-seed company that says it went from a high two-digit number of practices in May 2025 to more than 200 in November 2026; no revenue figure is published

| Fact | Value | Grade | Note | Sources |

Home page: „ZMV prüft, gibt frei“ (translation: the billing assistant checks and releases). | [5, 1] |
| AI model and data | model provider not named; the company calls the billing model its own | C | Company text on Startbase: "a proprietary AI model trained specifically on dental content automatically identifies the appropriate billing codes". FAQ: hosted only in Germany, and patient names and addresses are filtered out before the text reaches the AI. | [7, 4] |
| Platforms and integrations | web, iPhone, Android and Apple Watch; direct to teemer and Ivoris, a connector for Dampsoft | C | Pricing and integrations pages. For other practice software a small transfer window floats over it. The App Store page shows 3 ratings with an average of 5.0 and version 2.3.1 of 8 October 2026. | [2, 10, 8] |
| Time from launch to the November 2026 count | 20 months | calc | Calculated: March 2025 to November 2026. | [8, 1] |

How to read this table: a grade C value is a statement by the company, its investor or a directory that repeats the company. A grade E row marks the missing revenue figure. A "calc" value was computed on this page. No value is grade A or B.

## When did Dentero launch, and how did it grow? Timeline

From founding to more than 200 practices by the company's count, in about 21 months. Each entry carries its grade.

- **February 2025** (grade C [5]): Patrick Steingraf and Volker Tietz found Dentero Healthtech GmbH in Frankfurt am Main.
- **26 March 2025** (grade C [8]): Version 1.0.1 of the iPhone app, the oldest entry in the App Store version history.
- **May 2025** (grade C [5, 6]): BMH announces a pre-seed investment of a high six-figure amount with business angels, and says Dentero has a high two-digit number of customers, among them a clinic with 15 locations.
- **6 May 2026** (grade C [8]): App version 2.0 brings every function of the web version into the phone app. A new logo and colors follow on 10 June 2026, and an Apple Watch recorder on 31 July 2026.
- **7 November 2026** (grade C [1, 2]): The home page says more than 200 practices use Dentero and that it is now integrated directly into the practice software teemer. Plans cost €149 and €229 a month per practitioner, the pricing page lists.

## Why did Dentero work?

### Billing knowledge first

The company page says Dentero grew out of more than 35 years of billing expertise, through its advisor, and the CEO's text says he grew up with dental billing. The product does not stop at a transcript: it proposes the codes, the multiplier and the reason, and a member of staff releases them.

### On top of the practice software

A German practice already runs a PVS, a practice management system for appointments, records and bills. Dentero does not replace it: records and codes go straight into teemer and Ivoris, through a connector into Dampsoft, and through a small transfer window into any other system.

### Self-service trial, price per practitioner

The FAQ says a practice can start the 14-day trial by self-checkout in about 2 minutes, and the pricing page lists the price per practitioner who uses it, cancellable each month. That lowers the risk for a small practice to try it without a sales call.

## How it was built

These details come from the company's own pages, the App Store listing and its investor's press release. They are grade C.

- A web app at app.dentero.de, plus apps for iPhone, Android and Apple Watch. Version 2.0 of 6 May 2026 brought every web function into the phone app.
- Live transcription during the treatment. The FAQ says the AI is trained on the noise of a dental practice, such as suction and the drill turbine.
- Billing codes come from a model that the company calls its own, trained on dental content, combined with the rules of its billing advisor. The model provider is not named.
- Hosting only in Germany. Patients are identified by an ID, and names and addresses are filtered out before the text reaches the AI.
- Every record entry is stored with a time stamp, and changes are logged, so the record is audit-proof (revisionssicher).
- Payments for the subscriptions go through Stripe, the privacy page says. The marketing site is built with Astro.

## Who tried this before Dentero, and why did they fail?

Three companies in our database of failed startups promised to take paperwork away from health care with software. The values below are from that database and are not independently verified.

The failed startups come from our database of dead startups, retold here in our own words; Its entries are AI-assisted summaries of public sources, so they carry no evidence grade.

### Olive AI (2012 to 2023; funding US$852M; cause: Unit Economics)

- Promise: An AI workforce that handles prior authorizations, claims and billing for hospitals.
- Why it died: The database says much of the automation was expensive human-run robotic process automation, and the costs per customer never worked.
- Record: 

### Medisas (2013 to 2016; funding US$2M; cause: Competition)

- Promise: A cloud platform that replaces paper patient records in hospitals.
- Why it died: Large health-IT vendors, slow hospital sales cycles and regulation; it was too small to win.
- Record: 

### PatientBank (2016 to 2019; funding US$250K; cause: No Market Need)

- Promise: Patients request, store and share their medical records online.
- Why it died: Health systems and their rules did not move, and too few buyers wanted a patient-driven record service.
- Record: 

## What changed

All three sold to hospitals or patients a general promise to remove paperwork, and each had to change how large institutions work. Olive AI tried to automate many back-office tasks at once, and our database of failed startups lists US$852 million in funding spent on it. Medisas and PatientBank asked hospitals and patients to move their records to a new system, against large vendors and slow buyers.

Dentero picked one small, rule-heavy task: the record and the bill of one dental treatment, under three German fee schedules. It sells to small practices with a monthly price and a free trial, and it feeds the practice software they already use instead of replacing it.

## Can one person copy Dentero now?

**Verdict: The niche, yes; the billing knowledge, only with an expert.**

Many countries have their own fee schedules and record rules for doctors, dentists and therapists, and each one is a closed problem with exact rules. The software part, speech to a structured record, is now common. What made Dentero credible to practices, by its own account, was billing expertise built into the product and integrations with the local practice software.

1. Pick one profession and one country with complex billing codes.
2. Find a billing expert with decades of practice and build the rules with that person.
3. Integrate with the two or three practice systems that most of your buyers already run.
4. Price per user, monthly, with a self-service free trial.

**What is still open.** The same task for physiotherapists, veterinarians, orthodontists or doctors in other countries with their own fee schedules, where nobody has built the codes into the record yet.

## What could go wrong for Dentero?

- **What is not verified.** No revenue figure was found. The practice counts are the company's own: a high two-digit number of customers in May 2025, given by its investor BMH, and more than 200 practices on the home page on 7 November 2026. The customer logos and the quotes from named dentists on the site are the company's selection and were not checked with the practices. No payment-processor profile, founder interview with figures, or filed annual accounts were found. A reader could look for the annual accounts of Dentero Healthtech GmbH in the German company register, or ask practices named on the site.
- **Billing suggestions and responsibility.** Dentero proposes the multiplier and writes the reason for each fee, and its pages promise more fees for the practice („Mehr Honorar“). The home page says a billing assistant checks and releases each bill, so the practice stays responsible for whether a code and a reason match the treatment. The company page's claim that a practice loses 80,000 euros a year through incomplete documentation gives no source.
- **Recording patients.** For consent talks the app records the whole conversation and tells apart dentist, patient and assistant. The pages read do not say how a practice asks patients for consent to be recorded. The FAQ says data stays on servers in Germany and that names and addresses are filtered out before the text reaches the AI.
- **Competition and model providers.** Other dental stories on this site, Lavender Health, Patientdesk.ai, 10x and Healink, handle US insurance billing, phone calls or patient follow-up; Dentero is the only one built for German fee schedules. The company calls its billing model its own (company text on Startbase) and does not name a speech or language model provider, so how much it depends on outside providers is not known.
