Marketplaces have a fundamental discovery problem. Whether you're searching for a wedding venue or a specialized software developer, simple filters (Location, Price, Rating) are often too blunt to capture the nuance of human requirements.

Enter Miia, our specialized conversational agent designed for two-sided marketplaces.

Beyond the Chatbox

Most "AI assistants" on websites are simple support bots. They can answer basic questions or link to documentation, but they can't help you build an event. Miia is different because she is an Agent of Orchestration.

When we architected Miia, we focused on three technical pillars:

  1. Context Management: Miia remembers that you are looking for a venue in Zurich for 50 people, and she uses that context to filter every subsequent conversation about catering or music.
  2. Schema-Driven Recommendations: She doesn't just "talk"; she queries a structured PostgreSQL database via a precise API layer, ensuring her suggestions are real, available, and within your specified budget.
  3. Multi-Turn Dialogue: Event planning isn't a single question. It's a series of decisions. Miia is designed to guide the user through a logical workflow: Concept → Venue → Vendors → Quote.

The Technical Stack

To build an agent like Miia, we used a high-performance stack:

  • FastAPI Backend: For low-latency data processing.
  • RAG (Retrieval-Augmented Generation): Grounding the AI in specific marketplace data (profiles, descriptions, terms) to prevent hallucinations.
  • LangChain/OpenAI SDK: Orchestrating the complex logic flows between the user intent and the database.

The Value for Marketplaces

For the platform owner, a Miia-style assistant provides:

  • Higher Conversion: Users find what they need faster without getting frustrated by 20 filter checkboxes.
  • Proprietary Data Insights: Every conversation is a data point on what users actually want, allowing for better provider seeding.
  • Venture Studio Speed: 1D.works takes these complex products from concept to a deployed MVP in weeks, not months.

Conclusion

The era of the "Search & Filter" marketplace is ending. The era of the "Conversational Assistant" is beginning. 1D.works is proud to be at the forefront of this shift, building the intelligent backends that power the future of digital commerce.
