**The product.** A service that connects to an organisation's Facebook, Instagram, TikTok and YouTube accounts, reads every new comment, and hides the ones its models classify as hateful, vulgar, spam or toxic, links it flags as disinformation, and comments with keywords the client blocks, without notifying the author. Higher plans add sentiment analysis, recommended actions, drafted replies in the brand's voice and reports. Since 2026 it also offers an MCP server, so an AI agent such as Claude or ChatGPT can read and moderate the comments for the user.

**Why it worked.** Comment sections under the posts of politicians, news media, sports clubs and brands fill with abuse faster than people can delete it, and the platforms' own moderation is made for the platform, not for one account. The founders say no tool handled Slovak and other smaller languages well, so they trained their own models for each language with native speakers.

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

TrollWall AI does comment moderation: deciding which comments under a post stay visible. It uses a classifier, a machine-learning model that puts each comment into a category such as toxic, spam or acceptable, and then calls the social network's interface to hide the comment. The company's MCP page says comments are hidden "without notifying the author", and its FAQ says a client can approve a wrongly hidden comment again.

Tomáš Halász was a social media manager in 2022 and helped run an initiative for refugees from the war in Ukraine, where volunteers deleted hateful comments by hand. With three friends from IT projects, a CTO, a COO and a data scientist with a PhD and years of language-processing experience, he built a first version for internal use. They incorporated the company in March 2023 while still in their jobs, ITKeyMedia reported in May 2026. ITKeyMedia also reported a first investment of EUR 500K in December 2023 and an EUR 800K seed round in April 2026. Startitup wrote in April 2026 that clients in more than ten countries use it.

No revenue figure was found, so the evidence grade is E. What is checked is the founding team, the dates, the funding as reported in the press, the published prices and the client types the company and the press name.

How to read this table: a grade C value is what the company states on its own pages or what the press reports from the company and its investors. A "calc" value (grade X) was computed on this page. No value comes from a payment processor, a filing or a journalist's own check.

## When did TrollWall AI launch, and how did it grow? Timeline

From hand-deleted comments in 2022 to a paid moderation service with agents and an MCP server in 2026. Each entry carries its grade.

- **2022** (grade C [2, 4]): After the invasion of Ukraine, Tomáš Halász and volunteers delete hateful comments by hand; he and three friends build a first moderation model for Slovak for internal use.
- **March 2023** (grade C [4]): The four founders incorporate the company and keep their jobs; early users include heads of state, a telecom operator, brands and news media, ITKeyMedia reported.
- **December 2023** (grade C [4]): First investment, EUR 500K from CB ESPRI Impact One, as ITKeyMedia reported; the team works on it full time from 2024.
- **2024** (grade C [2, 5]): The company lists the Startup Awards Slovakia win in the Society category and a Latitude59 pitch competition final.
- **April 2026** (grade C [4, 5]): EUR 800K seed round led by Seed Starter of Slovenská sporiteľňa with Slovak Investment Holding and angel investor Miroslav Fedor, as Startitup and ITKeyMedia reported; clients in more than ten countries.
- **November 2026** (grade C [1, 3]): The site sells moderation and reply agents and an MCP server for AI agents, with published per-profile prices and a one-month free trial.

## Why did TrollWall AI work?

### One model per language and country

Halász told Startitup that the company does not train one universal model but adapts it to each country, with "viacero verzií rovnakého jazyka" (translation: "several versions of the same language"). ITKeyMedia reported that it works with external linguistic agencies and native speakers, which is slower but catches local slang and irony.

### Hide, do not delete, and leave the decision to people

The product hides comments without notifying the author, so the author is not provoked to post again. Halász told Startitup that the final decision must stay with a person, and the team says it moderates hate and abuse, not opinions or criticism.

### Sell to accounts that attract abuse

The client list named in the press, heads of state, political parties, a football club, a telecom operator, news media and an ice hockey championship, are accounts where abuse is constant and visible. The price is per social profile and comment volume, so a busy account pays more.

## How it was built

These details come from the company's own pages and from interviews the founder gave. They are grade C.

- The core hate detection is "fully developed in-house by the founders", Halász told ITKeyMedia in May 2026, and he said it outperforms generic GPT-based models in moderation quality.
- Models are trained with native speakers and external linguistic agencies for each language; Spanish has three variants for Latin American markets.
- Connections to Facebook, Instagram, TikTok and YouTube, a developer API, and an MCP server that the MCP page shows with Claude and ChatGPT as clients.
- Reply drafting, sentiment analysis and a customer knowledge base are part of the Pro plan; no downloaded page names the provider of the model that writes the replies.

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

Three companies in our database of failed startups tried to manage comments or social media accounts for brands 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.

### Livefyre (2007 to 2016; funding 67 (database value; units not given); cause: Competition)

- Promise: Real-time comment and social content tools that turned website comment sections into filtered conversations.
- Why it died: Disqus and Facebook Comments offered simpler integrations, and after Adobe bought it the product was absorbed into Adobe's suite.
- Record: 

### PostRocket (2011 to 2014; funding US$610K; cause: Product/Tech Failure)

- Promise: Data-driven timing of Facebook page posts to increase their reach.
- Why it died: Facebook changed its API and algorithm, and the company had no other platform to fall back on.
- Record: 

### ThinkUp (2010 to 2017; funding US$1M; cause: Competition)

- Promise: Personal analytics for social media accounts beyond likes and retweets.
- Why it died: The platforms built their own analytics and restricted API access, and larger suites such as Hootsuite and Buffer covered more needs.
- Record: 

## What changed

Livefyre ran its own comment system and lost to the free comments of large platforms. TrollWall AI does not replace the platform's comments; it works on top of Facebook, Instagram, TikTok and YouTube and only decides which comments to hide.

PostRocket and ThinkUp show the risk of living on one platform's API. TrollWall AI spreads over four platforms and a developer API, and language models made it practical to add drafted replies and sentiment reports on top of the classifier.

## Can one person copy TrollWall AI now?

**Verdict: Not alone, and not quickly.**

TrollWall AI needed four founders with IT, infrastructure and language-processing skills, its own trained models for many languages, work with native-speaker linguists, and two outside rounds. One person could copy a narrow version: comment moderation for one language or one type of account, built on a general model.

1. Pick one language or region where the large platforms moderate poorly.
2. Collect labelled examples of abuse with native speakers and test a classifier against them.
3. Hide rather than delete, and show the client what was hidden so they can check it.
4. Price per profile and comment volume, and start with accounts that receive abuse every day.

**What is still open.** Moderation for one under-served language, or for one kind of account such as local sports clubs, schools or town councils, at a price below agency rates.

## What could go wrong for TrollWall AI?

- **What is not verified.** No revenue figure was found. The company publishes prices but no revenue, no payment-processor profile was found, and the press reports give funding, not sales. The Slovak company register sites were not read because finstat.sk disallows Claude agents on company pages. The client and profile counts are the company's own. A reader could look for the company's annual accounts in the Slovak register of financial statements, or an investor interview with figures.
- **Political clients and hidden comments.** The home page says the product is "Trusted by Head of States, political parties", a For Politics page sells it to "political organizations, campaigns, and movements" with a testimonial from the social media manager of Petr Pavel's presidential campaign, and the careers page names political organizations as target clients; ITKeyMedia names a former Slovak president, the Czech president and political parties as users. The For Politics page says the agents "hide and moderate hate, misinformation, and manipulation" and calls this "Protect Your Narrative", and the FAQ says the product also hides "disinformation links, and any custom keywords you define in your blacklist". The MCP page says comments are hidden "without notifying the author". ITKeyMedia reported the team's view that "Legitimate criticism, political disagreement or sensitive discussion is not the target", and that the team sometimes pushes back on a client's definition of harmful content. These statements are the company's own; no downloaded page shows an outside check of what is hidden on political accounts.
- **Team and funding.** ITKeyMedia names four co-founders and says the company hired more people in 2024 after the first round. No downloaded page gives today's headcount; the careers page says "Currently no open positions" and also shows a sales manager role for Poland. The company raised EUR 500K in December 2023 and EUR 800K in April 2026, as ITKeyMedia and Startitup reported.
- **Badges and counts.** The home page shows a "Trusted by" logo wall and the about page lists awards; the logos were not checked one by one. The about page lists the Latitude59 2024 pitch competition as "Top 10 Finalist"; no outside page was checked for it. The home page counters say 52,000,000+ comments checked and 13,500,000+ toxic comments hidden, and the home page says clients in 17 countries while the For Politics page says 16; these counts are the company's own and were not checked. The home page says "19+ Languages" but lists 12, and ITKeyMedia counts 14.
- **Competition and model providers.** On this site, Watchdog sells an AI moderation bot for Discord, Telegram, WhatsApp and Reddit communities; TrollWall AI works on brand and public-figure accounts on Facebook, Instagram, TikTok and YouTube. Halász told ITKeyMedia the hate detection is developed in-house, and World In You wrote in 2025 that the model is "built upon open-source NLP models, trained with proprietary data", so the core does not depend on a paid model provider; the product does depend on the four platforms' interfaces, and no page names the provider of the reply-drafting model.
