What does NFTstack (NFT tools directory run by Grok Bot @StSola) sell, and to whom?
Free NFT/on-chain tools directory + featured listings from $39/week + newsletter sponsorships.
NFT creators, collectors and builders hunting marketplaces, mint tooling, analytics, wallets and Dev Kits — plus NFT-tool vendors who want featured/homepage or newsletter placement [1][3].
How was NFTstack (NFT tools directory run by Grok Bot @StSola) built?
Built and run by the founder’s Grok Bot (@StSola); the bot handles daily updates, the newsletter and sponsor outreach [4]. Sources for the directory: curated research, DefiLlama, GitHub, Product Hunt, Hacker News, DEV, ecosystem blogs [1]. Chain Pulse pulls NFT volume by chain from DefiLlama’s public API [2]. Contact hello@stsola.us [1].
What is the business model?
Free directory + paid placements: Featured homepage $39/week, category/chain pin $29/week, newsletter classified $75/5 sends, newsletter primary $150/send (introductory rate card), fast-track review $19 [3]. Dev Kits marketplace lets sellers use their own checkout; NFTstack only charges for featured placement [3]. Affiliate/revenue total not disclosed on-site [1][3].
Where does the traffic come from?
nftstack.net directory, Chain Pulse, Dev Kits, daily email, RSS, live dashboard [1][2]; @StSola on X (stated on site footer and Agent-Built Businesses) [1][4]; sponsor page rate card [3].
What revenue has NFTstack (NFT tools directory run by Grok Bot @StSola) reported?
Reported revenue: Not disclosed (rate card live; first sponsor pitched), per Sponsor rate card + Agent-Built Businesses (pitch noted, no total) (2026-11-04).
What does the agent do, and what does the human do?
What does it cost to run?
Not disclosed. Runs on Grok Bot [4]; domain + hosting implied. Sponsor outreach is agent-run.
What worked and what didn't?
How to copy NFTstack fast
A starter path written by AI from this case. Budgets and timings are our estimates, not the operator's numbers.
Inference One Grok Bot plan (standard ~$30); NFTstack was on Day 24 when checked [1][4]. Closest public Grok Bot template for a niche directory. It will not pull DefiLlama or run a sponsor rate card by itself — closest match.

Key moves from the original case
- Own a vertical (NFT tools only) instead of another AI directory
- Pipe a public data API (DefiLlama) into a daily 'pulse' page
- Publish an introductory rate card before you have big traffic
- Say the AI CEO runs updates and sponsor outreach
What are the risks and the moat?
Tiny email list [1]. NFT market cycles swing traffic. Sponsor revenue unproven in public [4]. Rate-card prices may stay introductory for a long time.
