The Cheapest AI Business to Start (Real Startup Costs, Not Guesses)
The cheapest AI businesses to start, ranked by the startup cost each source actually disclosed: $0 to about $31, plus the $25 and $99 app-store routes.
Most lists of cheap AI businesses use the author’s guess for startup cost. In our directory, startup cost is left blank unless the source discloses it. Of about 1,800 stacks, only about 300 have a disclosed number, and most of those are the $99 Apple developer fee. Here is everything at the very bottom, cheapest first.
Under $35 to start
| Stack | Disclosed startup cost | Reported result | Proof |
|---|---|---|---|
| AI-Curated Niche Newsletter | $0 (beehiiv affiliate link Free, free automation and AI tiers) | AI Central reports $150k+ from beehiiv’s affiliate link ad network | Self-reported, vendor case study |
| Amazon KDP Low-Content Books | $0 (KDP is free to publish) | $0 to $1.5k a month range | Self-reported |
| AI LinkedIn Ghostwriting | $0 with free AI tiers | $0 to $10k+ a month range | Self-reported |
| AI-Coded Add-On for Notion or Chrome | $0 (Chrome Web Store adds a $5 one-time fee) | $0 to $5k+ a month range | Self-reported |
| Agent-Built Directory Business | About $1 (promo domain, free tiers) | $1,800 in about 10 days | Self-reported |
| Programmatic SEO Affiliate Site | About $6 (domain + $5 API credit) | $0 to $3k a month range | Self-reported |

| AI-Built Local Lead-Gen Site | About $13 (domain + tokens) | $0 cash so far | Self-reported |
| AI Implementation Consultant | $20 total, per the guest | $15,000/mo profit | Self-reported, podcast |
| Android Transcription App | $25 Google Play fee | ~$715 MRR | Verified (RevenueCat, Oct 2026) |
| AI Stock Image Contributor | About $30 a month in tools | $3,976 in year one | Self-reported |
| Etsy Print-on-Demand with AI Designs | Under $40 ($31 itemized) | $0 to $2k a month range | Self-reported |
Ranges like “$0 to $5k” are what operators in that model report, not what a beginner should expect. Several are $0 for long stretches.
The cheapest one with verified revenue
The Android transcription app is the cheapest start in our data with verified revenue: a $25 Google Play fee, and about $715 MRR checked through RevenueCat on TrustMRR. The source says growth was organic, with no ads. You do need to be able to build an app (AI coding tools make this easier, not effortless).
The $99 tier
About 290 verified stacks list $99 a year, the Apple Developer Program fee, as their only disclosed cost. They are iPhone apps: calorie trackers, plant and gem identifiers, color analysis, AI tutors. Revenue in that group runs from a few dollars to over $20,000 MRR. Other costs (API bills, ads, design) are not disclosed, so treat $99 as the floor, not the total.
What “cheap” hides
- Your time is the real cost. Every cheap option above needs weeks of work before the first dollar.
- Free tiers have limits. Make, beehiiv affiliate link and AI APIs all start charging once you grow.
- Distribution is not free. The cheap businesses that worked had an audience, a network, or search traffic.
How to choose
- Can you sell to people you already know? Start a service (ghostwriting, consulting). Fastest first dollar.
- Can you write and wait? Start a newsletter or SEO site. Slow, but it compounds.
- Can you build? Ship a small app for $25 (Android) or $99 (Apple).
