🏆 Funding Tiers
What Makes a Tier S Tool?
We don’t pay for raw data dumps. We pay for answers.| Feature | Raw Data (Tier B) | Curated Intelligence (Tier S) |
|---|---|---|
| Crypto | ”Here’s the transaction list" | "Top 5 whales accumulating this token right now” |
| Finance | ”Here’s the SEC filing PDF" | "Key risk factors extracted with sentiment score” |
| E-commerce | ”Here are Amazon search results" | "Estimated monthly revenue: $47K, trending up 23%“ |
| Competitive Intel | ”Here’s their homepage HTML" | "Tech stack: Stripe, Vercel, Segment. 2.3M monthly visitors” |
🦄 Tier S: $1,000 + Revenue Share
High-value tools that replace expensive subscriptions. These unlock data people currently pay $500–$20,000/year for. Complex pipelines, novel analysis, or hard-to-access sources.🛠️ Tier A: $250-$500 + Revenue Share
High-utility tools agents query frequently. Reliable, well-documented tools that solve common needs. Think “best-in-class API wrapper with smart curation.”🚀 Tier B: Revenue Share Only
Simple wrappers and adapters. No upfront grant, but immediate listing. Start earning from day one.All tiers earn revenue share. Even Tier B tools generate USDC the moment an agent queries them. You keep 90% of every fee.
🔍 How to Find Unbundling Opportunities
Before pitching, do this research. Here’s a real example of how to identify a fundable tool:Example: Finding a SensorTower Unbundling Opportunity
Step 1: Search for frustrated paying users Go to Grok and search Twitter:"SensorTower" "pay" OR "subscription" OR "expensive""app analytics" "not worth" OR "canceled" OR "only need"
“I pay $400/month for SensorTower just to check competitor download estimates before investor calls. Everything else in the dashboard I never touch.”
“SensorTower is worth it for the App Store keyword rankings alone. Rest is noise.”Step 3: Isolate the $0.10 query From this research, you’d identify: “App download estimates by bundle ID” is the core value. Build a tool that delivers just that. The specific data point people are paying $5K/year to access occasionally. Step 4: Pitch with evidence Your proposal should say: “SensorTower charges $5K/year. Users on Twitter report paying primarily for download estimates. Here’s my tool that delivers that specific data point for $0.10/query. Here are 3 tweets proving demand.”
This is the bar. Every idea below has been evaluated against this standard. If you’re pitching something not on this list, show us you’ve done this research.
📋 Request for Builders (RFB)
We’re actively funding tools across these verticals. These ideas target specific features of expensive subscriptions, not commodity data. If you have a novel idea with evidence of an expensive paywall, pitch it.🏢 Competitive Intelligence & Sales
Replaces: ZoomInfo ($15K/yr), SensorTower ($5K/yr), BuiltWith ($3K/yr), SimilarWeb| Tool Idea | Description | Tier |

📈 Financial Markets & Research
Replaces: Bloomberg ($24K/yr), FactSet ($12K/yr), Capital IQ ($20K/yr) Bloomberg’s value is parsed, structured financial data with analysis, not raw filings you can get from EDGAR for free. Build tools that do the heavy lifting of extraction and interpretation.| Tool Idea | Description | Tier |
|---|---|---|
| SEC Filing Parser | Turn 10-K/10-Q into structured JSON with key metrics, risk factors, and YoY changes | S |

⚡ Crypto & DeFi
Replaces: Nansen ($2.5K/yr), Arkham ($1.5K/yr) Nansen’s value isn’t rug checking or gas prices. It’s wallet labeling, smart money identification, and entity clustering. That’s what people pay $2.5K/year for. Build tools that deliver those specific insights.| Tool Idea | Description | Tier |
|---|---|---|
| Wallet Profiler | Total P&L, biggest wins, current positions, activity patterns (the core Nansen feature) | S |
| Smart Money Tracker | Who are the wallets with consistent alpha? What are they accumulating right now? | S |

What we’re NOT funding in crypto: Honeypot detectors, gas oracles, yield aggregators, bridge routers, funding rate scanners. These are already solved by free tools (DeFiLlama, CoinGecko, exchange APIs) with no premium tier worth unbundling. The $2.5K/year Nansen subscription exists because of wallet intelligence. That’s where the value is.
