**The product.** A browser app in which a person holds a spoken practice conversation with an AI character, for example a critical-feedback talk with a reserved employee, a cold call to a sceptical buyer or a call with an upset customer. A second AI scores the conversation against goals set for the scenario and quotes the transcript, and an AI coach goes through the result. Individuals and teams of up to 12 buy plans online; training companies resell it under their own brand.

**Why it worked.** Companies teach these conversations in one-day seminars, and people rarely get to practise them before the real talk. The founder put a first, quickly built version on a German-language website, and large German companies asked for demos before the product was ready. Getting such companies to buy directly was slow, so the company now sells mainly through training and consulting firms that already run leadership seminars and buy conversations in packages.

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

Careertrainer.ai is an AI role-play product: a practice conversation in which a large language model, a program trained on large amounts of text to produce answers, plays a person with a role, a goal and a temper, and the user speaks to it by voice. A separate model then scores whether the scenario's goals were met and backs each judgement with a quote from the transcript. The pricing page lists a free tier of 3 conversations a month and paid plans from €14.99 a month.

Jannik Lindner, from Baden in Austria, started it as an idea in parallel with other products and brought in Markus Nedwed as co-founder, who builds the software. In the Happy Bootstrapping podcast of April 2026 Lindner said the first version was "komplettes Vibe-Coding" (translation: completely vibe-coded) and that the company grows mainly through white-label partners, firms that sell the product to their own clients under their own brand. A March 2025 copy of the site shows a free beta; the changelog dates version 1.0, with paid plans and the white-label launch, to 1 February 2026.

No revenue figure was found in any source. The evidence on this page is the company's own pages and one founder interview, so it shows that the business exists and sells, not how much it earns.

## When did Careertrainer.ai launch, and how did it grow? Timeline

From a free beta in German to a paid platform sold through training firms, in about 20 months. Each entry carries its grade.

- **2025** (grade C [2]): Lindner tries to work alone, finds it does not suit him, and brings in Markus as co-founder to build Careertrainer.
- **10 March 2025** (grade C [8]): The German site offers AI role-plays for leaders as a free beta.
- **21 December 2025** (grade C [5]): Version 0.9.0, a pre-release with scenario import for partners.
- **1 February 2026** (grade C [5]): Version 1.0: white-label launch for training and HR partners, managed payments, pricing dashboard.
- **10 April 2026** (grade C [5]): Version 2.0, a relaunch for sales teams and HR departments with team dashboards.
- **16 April 2026** (grade C [1, 2]): Happy Bootstrapping episode 168: growth mainly through white-label partners; first English demo call that week.
- **11 October 2026** (grade C [5, 3]): Version 2.13.0; the pricing page lists four areas and plans from €14.99 a month.

## Why did Careertrainer.ai work?

### Two models, two jobs

One model plays the character and only knows what that person would know. A second model scores the conversation against the goals set before it started and quotes the transcript. The founder said this split is hard to get from a home-made chat with a general assistant, and the pricing page says ChatGPT lacks a counterpart with real behaviour and a separate evaluation.

### Resellers instead of enterprise sales

Large companies asked early, but the founder said it was hard to bring the new product into them. Training and consulting firms that already sell leadership seminars now buy conversation packages and use the product between their own sessions, under their own brand if they want.

### Pages per industry for AI assistants

The founder said many buyers arrive through pages such as leadership training for the IT or pharma industry, which have little classic search volume, and that he writes them for language-model answers so that ChatGPT names Careertrainer when someone from that industry asks.

## How it was built

These details come from the founder in the podcast and from the company's pricing and changelog pages. They are grade C.

- The first version was vibe-coded, that is, written mostly by asking an AI coding tool; the founder said conversations sometimes broke off. A rebuilt, better-structured version followed.
- Character and evaluation run on separate language models; the pricing page names OpenAI and Anthropic as the AI model providers.
- Live voice runs over LiveKit, an open-source WebRTC service for real-time audio; servers are at Hetzner in Frankfurt; the page lists Stripe as a processor.
- The changelog shows about 20 releases between December 2025 and October 2026.

## Who tried this before Careertrainer.ai, and why did they fail?

Three companies in our database of failed startups sold training to companies and failed on long enterprise sales or on cost. 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.

### Hickory (2015 to 2018; funding US$2.5M; cause: Competition)

- Promise: Corporate training personalised to each employee's performance.
- Why it died: Enterprise sales cycles were longer than planned, and cheaper content libraries won the budget.
- Record: 

### Pluralsight (2004 to 2024; funding US$4B; cause: Unit Economics)

- Promise: Video courses that keep a company's developers current.
- Why it died: Enterprise deals cost more to win than they returned, and free video and AI made recorded courses cheap.
- Record: 

### Udacity (2011 to 2024; funding US$1B; cause: No Market Need)

- Promise: Online courses that lead to jobs in technology.
- Why it died: Most students never finished, so certificates meant little to employers.
- Record: 

## What changed

The three predecessors sold content: courses and modules that had to be produced, kept current and finished by the learner. Hickory and Pluralsight also had to win long enterprise contracts. Careertrainer.ai sells practice instead: the language model produces each counterpart on demand, so a new scenario is a description, not a recorded course.

It also avoids most direct enterprise sales by selling through firms that already have the client relationship and the seminar budget. Whether these partners bring enough volume is not shown in any source.

## Can one person copy Careertrainer.ai now?

**Verdict: Yes, with two people and a partner channel.**

The product is a scenario library, two model calls and a voice connection, built first with AI coding tools. The harder part is distribution: the founder found that training firms sell it better than he could sell it to large companies himself.

1. Pick a conversation that people train in seminars and fear in real life, and write scenarios with a goal and a character.
2. Use one model for the character and a separate one for scoring against the goals, with quotes from the transcript.
3. Charge per completed conversation, so partners can resell packages to their clients.
4. Offer the product under the partner's brand, with a data processing agreement for European buyers.

**What is still open.** Other conversations that are trained with actors or colleagues today: bank advice, medical and care talks, interviews, debt collection calls, in other languages than German and English.

## What could go wrong for Careertrainer.ai?

- **What is not verified.** No revenue figure was found. The founder did not give one in the Happy Bootstrapping interview of April 2026, and there is no payment-processor profile, filing or second interview. The about page's "500+ Companies trust us" and "Ø 8× ROI for companies" have no source or method on the page. A reader could look for a TrustMRR profile, a later interview or partner announcements.
- **Competition.** The founder named US companies with venture funding in AI role-play, among them Yoodli, which he said raised "30 Millionen oder so" (translation: 30 million or so). On this site, SimCare sells voice role-play to counselling and care schools and Fathom AI sells sales coaching with an AI buyer; Careertrainer.ai is the German-language, partner-sold version for leadership and sales.
- **Dependence on model providers.** The pricing page names OpenAI and Anthropic as the AI models that receive anonymised data, and LiveKit for live audio. A price or policy change at these providers changes the cost of every conversation, which is the unit Careertrainer.ai bills.
- **Pages that disagree.** The pricing page says partners use a white-label platform "with no setup fee"; the partner page says white label costs "a one-off setup fee for branding, subdomain and email delivery". The partner page also says the partner's clients do not see Careertrainer in the interface, and that it is listed as a sub-processor in the data processing agreement.
- **Training data about employees.** The product records conversations of employees. The pricing page says transcripts are visible only to the person who spoke, team reports are aggregated, and it is "a training instrument, not a control instrument"; organisation plans include a works-council template.
- **The founder's other businesses.** Lindner also co-founded rawshot.ai, AI product photos for fashion shops, with two other partners, and he said that is his main job. The podcast page says his earlier affiliate company ran sites such as Supplementbibel.de. The Careertrainer.ai pages read here do not link to either.
