No code examples on homepage
Homepage is purely marketing-focused with no indication this is a developer product until you dig into docs
Confusing pricing page
Only 'Talk to Sales' option makes it unclear what API usage will cost, creating friction for developers
Critical Issues
Developer-first positioning missing
Impact: Developers may not recognize this as a tool for them
Developer behavior: Will likely bounce from homepage without exploring the API capabilities
No SDK or language-specific tooling
Impact: Higher integration friction
Developer behavior: Developers expect SDKs for production use; REST-only increases implementation time
Unclear pricing and trial limitations
Impact: Prevents developers from starting
Developer behavior: Won't begin integration without understanding costs and limits
Quick Wins
Add code examples to homepage hero section
Immediately signals to developers this is for them
low effortCreate clear API pricing tiers with usage limits
Removes friction for developers to start testing
medium effortAdd developer-focused navigation and messaging
Better developer recognition and engagement
low effortStrategic Opportunities
Gap: Only REST API, no SDKs or CLI tools
Impact: High integration friction limits adoption
Build SDKs for popular languages (Python, JavaScript, Go) and distribute via package managers
Gap: No visible community presence or support channels
Impact: Developers can't get help or share knowledge
Create Discord/Slack community, Stack Overflow presence, and developer advocates
Gap: No architecture diagrams or workflow examples
Impact: Unclear how to integrate into existing systems
Create integration guides for common use cases and architecture patterns
What This Score Can't Tell You
This evaluation is based on your public-facing web presence. Only hands-on testing by real developers can reveal:
- Whether the API rate limits are reasonable for typical use cases and how they compare to competitors
- How accurate and fresh the people/company data actually is compared to other data enrichment APIs
- The actual API response times and reliability under load
- How well the structured data extraction works with edge cases and incomplete profiles
- Whether the 'AI agents' provide significantly better results than traditional data enrichment services
