**The product.** A chat app with one monthly price that includes models from OpenAI, Anthropic, Google, Perplexity, Grok and others. Mono picks a model for each task, keeps one memory across all models, runs research with several models at once, and adds projects, skills, plugins and a filter that hides names and personal data from the model providers.

**Why it worked.** People who pay for ChatGPT, Claude, Gemini and Perplexity separately can pay once instead. The founder sets one price for all models because a user sends about the same number of messages in one tool as in several, and he limits only the most expensive models. He adds new models as they appear, often several in one week, and publishes the revenue daily.

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

Mono is a model aggregator: a product that buys access to the AI models of several companies and sells them to the user under one subscription and one chat window. Mono calls the models through their API, the paid programming interface that a model company sells to other software, and pays for each request. Its automatic model selection reads each prompt, decides what kind of task it is (a quick answer, research, writing, code, an image) and sends it to the model that the founder chose for that task. The user can change that choice in the settings.

Jonas Kamber, a Swiss software developer and UX designer, built and runs it alone. Solid Technologies AG in Lucerne, where he is the managing director, operates it. His TrustMRR profile gives 1 November 2025 as the founding date; the first payments arrived in December 2025, and version 1.0 was released on 20 January 2026. On 7 November 2026, Stripe data read by TrustMRR showed US$10,815 in monthly recurring revenue (MRR), the monthly value of all active subscriptions, from 393 active subscriptions. That is about US$130,000 a year if nothing changes. Total verified revenue since the start was US$84,993.

The money figures are grade A: TrustMRR reads them from Stripe through an API key. The team size, the founding date and "bootstrapped" are what the founder entered on TrustMRR. Cash received in the last 30 days (US$10,463) was 30.1% below the 30 days before, while MRR rose 5.5%, so the page marks the trend as falling. Below are four earlier companies that promised one place for many services and failed.

## Pricing

Mono prices per user on 7 November 2026, from the company's pricing page (grade C); prices exclude VAT

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Mono | 17 | 20 | all models and features; limited use of the most expensive models |
| Mono Pro | 29 | 34 | larger file uploads, 2x use of limited models, priority support |
| Mono Max | 81.67 | 96 | 6x use of limited models; up to 660 images or 450 messages with the most limited models |

Yearly prices are US$204, US$348 and US$980 a year; the column shows them divided by 12. The page says the Pro yearly plan saves US$54, but 12 times US$34 minus US$348 is US$60 (calc). About half of the models have usage limits because of their cost, and the page says 95% of users do not reach them. The first 10 messages are free. A workspace with more than 10 paying members gets 10% off Mono Pro and Mono Max.

How to read this table: a grade A value comes from Stripe, the payment processor, as read by TrustMRR through an API key. A grade B value is a third party that copied those figures. A grade C value is what the founder or the company's own pages say. A "calc" value was computed on this page from the rows above it.

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

From a founding date in November 2025 to more than 390 paying subscriptions in November 2026, with a new release almost every day. Each entry carries its grade.

## Why did Mono work?

### One flat price for many models

The pricing page explains the price: Mono may replace ChatGPT, Gemini, Claude and Perplexity for a user, but the user still sends about the same number of messages a month, not five times as many. So one subscription of US$20 can carry the cost of several providers. The average subscription was about US$27.52 a month in November 2026 (calc).

### Limits only on the expensive models

About half of the models have usage limits because of their cost, and weekly limits started on 14 September 2026. The page says 95% of users do not reach them. Users who do are sent to Mono Max at US$96 a month, which raises the limits six times.

### The model choice is part of the product

Automatic model selection sends each prompt to the model the founder picked for that kind of task, for example Perplexity for research with sources and a DeepSeek model for code. The change log adds new models almost every week, for example Claude Opus 5.5 on 22 September 2026 and Gemini 4 Argon on 14 October 2026. The user buys the choice, not one model.

### Revenue in public

The about page says all revenue figures, milestones and setbacks are public, that revenue is published daily on TrustMRR, and that the founder writes daily on LinkedIn about product decisions and failures. No source says how many customers came from these posts, so the channel on this page is unknown.

## How it was built

These details come from the company's own pages and the tech-stack section of the TrustMRR profile. They are grade C.

- JavaScript, HTML5 and CSS in the browser and Node.js on the server; Stripe for payments (TrustMRR tech stack).
- Models from OpenAI, Anthropic, Google, Perplexity, Grok, DeepSeek, Z.AI GLM, Mistral, Kimi and the Swiss model Apertus, each added in a release note.
- Privacy: the home page says no data is used for training and that Mono made the opt-out where a provider requires one; an anonymization layer (May 2026) hides chosen terms and personal data from the providers.
- Plugins (August 2026) connect calendars, project tools, CRMs and apps such as Canva, SharePoint, Miro and Power BI; any other source can be connected through MCP, the Model Context Protocol, a standard way for an AI app to read other systems.
- Single sign-on (July 2026), project sharing and team workspaces for companies.
- The about page says the founder worked for years as a software developer and UX designer before Mono and has 20 years of experience in digital product development.

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

Four companies in our database of failed startups promised one place for many outside services and failed. 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.

### Fanhattan (2010 to 2016; funding US$21M; cause: Competition)

- Promise: One search across every streaming service for films and TV shows.
- Why it died: It did not reach enough users, and Roku and the streaming services built their own search and discovery.
- Record: 

### SetJam (2009 to 2013; funding US$2.1M; cause: Competition)

- Promise: One place to search and watch TV shows and films from many streaming services.
- Why it died: Netflix and Hulu grew their own libraries, and SetJam had no content licenses of its own.
- Record: 

### Singly (2011 to 2016; funding US$2.7M; cause: Competition)

- Promise: One API for a user's data from many social networks and online services.
- Why it died: It depended on other companies' APIs, which changed and limited it, and Zapier and IFTTT offered more.
- Record: 

### Flux (2015 to 2018; funding US$7M; cause: Team/Founder Conflict)

- Promise: One inbox for Slack, email, WhatsApp and other messaging apps.
- Why it died: The platforms kept changing and breaking the integrations, and the money went into repairs.
- Record: 

## What changed

Each of the four put many outside services behind one screen, and each depended on companies that could build the same screen themselves or stop the access. Mono is the same kind of bet: ChatGPT, Claude and Gemini, the apps that Mono's pricing page says it can replace, are sold by the same companies that sell Mono its models.

Two things differ. First, the model companies sell API access to other software on purpose and charge for every request, so Mono pays a published price instead of depending on goodwill, a content license or an unofficial connection. Second, Mono charges the user directly from the first month, while the failed-startup database records say Fanhattan relied on affiliate fees and SetJam had no direct payments from users. The open risk is the margin: Mono pays the providers per request and sells a flat price, so heavy users and expensive new models cost it money, which is why it added weekly limits in September 2026.

## Can one person copy Mono now?

**Verdict: Yes, but the margin is thin and the providers set the costs.**

One developer built this in about a year with no outside money, and the AI Receipts newsletter rates it as replicable. The building blocks are public: model APIs, Stripe and open standards such as MCP. What has to be copied is the work around them: choosing a model for each task, adding new models quickly, holding the cost of heavy users under the price, and publishing numbers that make strangers trust a new brand.

1. Pick a market where one brand is not yet strong, for example one language or one country, as Mono did with a German interface and a Swiss company.
2. Set one price and limit only the expensive models, with a higher plan for heavy users.
3. Route each task to a model automatically, and let users override the choice.
4. Watch cost per user every week; add usage limits before the expensive models eat the margin.

**What is still open.** Aggregators for one profession or one regulated market (law, health administration, public offices) that need data rules the big chat apps do not offer, and for languages the big apps serve badly.

## What could go wrong for Mono?

- **Cash below the subscription value.** Revenue in the last 30 days was US$10,463, 30.1% below the 30 days before, and October 2026 (US$11,321) was 27.3% below September (US$15,566) (calc), while MRR grew 5.5% in the same 30 days (TrustMRR). The AI Receipts reads this as yearly plans still counting in MRR while monthly cash cooled. September may have included yearly payments.
- **The founder's own entries.** The team of 1 person, the founding date of 1 November 2025 and "Bootstrapped" are founder-provided on TrustMRR; only the payment metrics are read from Stripe. The register date of Solid Technologies AG, the company that operates Mono, was not checked because the Swiss commercial register disallows automated agents.
- **Skills for children, hiring and photos.** The free skills that Mono publishes include Homework, "a patient AI tutor for children" that works from a photo of a worksheet and says it guides "without giving answers directly"; Shortlist, which ranks job candidates by "an objective match percentage" from their CVs; Taken with my Phone, which turns polished marketing or real estate photos into images that look "genuinely taken with an ordinary phone", with a hotel room as the example; and No Slop, which removes "obviously AI sounding phrasing". No Slop does not claim to pass AI detectors, and the same list offers an AI Detector skill. None of these pages says how the results should be labeled or checked.
- **Health and plugins that act for the user.** The home page says the GLM model is "great for nutrition and calorie planning or a first look at symptoms"; health is one of the task types on the home page, not the product. Since 6 October 2026 the change log lists plugins for Instagram, Meta Ads, Facebook, LinkedIn and Wix, and the plugins page says Mono can "act on your behalf" in connected apps; the pages do not say which actions these plugins take.
- **Testimonials not checked.** The home page shows four short quotes with names, one of them a first name only ("Luca"). We could not check who wrote them.
- **Competition.** On this site Magai sells the same kind of one-subscription access to many models and TypingMind sells a chat window for people's own API keys; The AI Receipts names Kolbo.AI, another aggregator, as the closest peer on its board at about US$41,200 MRR in November 2026.
- **Dependence on the model providers.** Every answer is bought from another company: the about page says the subscription pays "for the AI compute (inference)", and the pricing page says about half of the models are limited "due to the high costs". The change log shows the dependence: an option to exclude OpenAI (March 2026), a Claude model that was added on 11 June 2026, given a privacy warning the same day and removed on 12 June, and weekly usage limits (September 2026). A price change by one provider changes Mono's margin.
