🚀 What Inspired CultureGraph?

In today’s fast-paced startup world, building with the right co-founder is more important than ever. While skillsets matter, cultural alignment—shared tastes, values, and worldviews—can make or break a startup. Inspired by this insight and powered by Qloo’s cultural AI, we built CultureGraph to answer the question: “How aligned are two people, beyond the résumé?”

🛠️ How We Built It

We used:

  • Qloo API for taste profiling: converting movies, books, travel, and lifestyle inputs into interpretable cultural vectors.
  • Google Gemini API for reasoning: analyzing longform scenario responses for alignment in thinking.
  • scikit-learn with TF-IDF + cosine similarity for NLP sentiment-based scoring.
  • Streamlit for the web interface and logging.
  • Python to build a lightweight, reproducible experience.

We stored user profiles as JSON and ran batch compatibility checks by comparing new inputs with existing profiles in a master log. Each match includes:

  • Qloo taste similarity
  • NLP sentiment alignment
  • Gemini’s LLM-backed compatibility reasoning

🧠 What We Learned

  • How to leverage multi-modal compatibility signals (structured + unstructured data)
  • Prompt engineering and response scoring with Gemini
  • Combining embeddings, semantic search, and user preferences
  • Deploying live apps using Streamlit Community Cloud

😓 Challenges We Faced

  • Ensuring diverse entity coverage with Qloo’s limited response to ambiguous terms
  • Handling varied input formats and aligning them into a unified compatibility framework
  • Gemini's output needed structure – prompting and postprocessing took iterations
  • Maintaining state management and logs within Streamlit without database overhead

📈 Future Improvements

  • Add visual graph-based network view of co-founder clusters
  • Include MBTI/Big Five-style personality questions for deeper analysis
  • Gamify the experience with points and matchmaking suggestions
  • Expand support for team compatibility (3+ founders)
  • Integrate with LinkedIn or Notion for faster data prefill

❤️ Final Thoughts

CultureGraph is more than a tool – it's a prototype for a future where AI helps us build relationships and teams that last. Whether you're building a startup or just curious about cultural alignment, this platform gives a fresh, data-driven lens into human compatibility.
