Key points

How big the income is

All five are self-reported: Six Atomic at 40,000 dollars a month (2022, 22 people); Truein at 40,000 dollars MRR (2021, 20 employees); ChatSEO at about 14,000 euros a month; Topliner above 10,000 dollars a month; EvyAI says it is approaching a million dollars a year, not counting the founder's agency.

Vertical SaaS usually takes a team: 22 people at Six Atomic, 20 employees at Truein
Two figures are years old with no public update
EvyAI's revenue is counted apart from the founder's agency

Acquisition is the hard part

Truein's reseller partnerships failed and organic search grew slower than hoped, so it turned to paid ads; Six Atomic's technology is new enough that buyers struggle to grasp it and niche search volume is low, so it relies on talks, op-eds and referrals; ChatSEO runs on organic traffic alone.

Niche industries have little search volume
Referrals and industry exposure matter more than ads
Free mini-tools can bring organic traffic

Dependencies and risks

ChatSEO depends entirely on access to Google Search Console; EvyAI depends on LinkedIn's rules; Topliner is tightly bound to one agency, with no site or pricing to check; Truein's face-recognition attendance means handling employees' face data.

Dependence on other platforms' access and rules
Tied too closely to one company
Face and payroll data need compliant handling

Tools

Tools and platforms the cases mention. Every link goes to the official site, and we earn nothing from them.

Tool	Used for	Link
Claude Code	ChatSEO builds its free SEO mini-tools with it	Official site ↗
Google Search Console	Where ChatSEO reads users' site data	Official site ↗
Chrome Web Store	Where browser extensions such as EvyAI are published	Official site ↗
LinkedIn	The platform where EvyAI drafts users' posts and comments	Official site ↗
Google Ads	Truein's paid acquisition channel	Official site ↗

Platform rules and compliance

Reading data from Google Search Console, LinkedIn and similar platforms must follow their API and automation terms; when a platform tightens them, the product suffers.
Face recognition uses biometric data, which many jurisdictions treat as sensitive and allow only with notice and explicit consent (for example the EU's GDPR and China's Personal Information Protection Law); check local rules before launch.
Chrome extensions must follow the Chrome Web Store developer policies and state which page data they read.
Business customers often ask for a data-processing agreement and security documentation; have them ready before signing.

FAQ

How much can vertical AI SaaS make?

All five of our cases are self-reported: four make 10,000 to 40,000 dollars or euros a month, and EvyAI says it is approaching a million dollars a year. Two of the figures date from 2021 and 2022 with no update since.

Can one person do it?

It is harder: ChatSEO has three co-founders, Six Atomic 22 people and Truein 20 employees, and both Topliner and EvyAI have an agency behind them.

Where do the first customers come from?

Mostly from the founders' own trades: Topliner from a co-founder's recruiting agency, EvyAI from the founder's LinkedIn training audience, Truein's early customers from his network and cold calls.

Do I need ads?

It depends on the industry: ChatSEO spent nothing on ads and relies on free mini-tools for organic traffic; Truein's founder says Google ads return about 2 dollars per dollar.

What is the biggest risk?

Depending on other platforms (Google Search Console, LinkedIn) or a single partner; sensitive data such as faces also has to be handled lawfully.
