nBases — AI Platform for Mid-Term Rentals

AI-powered platform helping remote workers and property managers qualify mid-term rentals.

nBases started from a personal pain point and evolved through multiple iterations, from manual deals to an AI-driven B2B platform.

Key Evolutions

1. Manual validation (0→1)

Negotiated and upgraded apartments for digital nomads, closed first bookings manually to validate demand.

2. AI-powered listing analysis

Built an AI system to score Airbnb listings and launched:

  • a public website with AI-scored properties
  • a Chrome extension analyzing listings directly on Airbnb
AI-analyzed listings website

3. B2B SaaS for property managers

Pivoted to a widget SaaS allowing property managers to display AI scores and improve conversion.
