Propelos Introduces Conversational AI Search for European Luxury Real Estate

Propelos has launched an AI-based property search tool for luxury real estate agencies in Europe. The solution allows buyers to search for properties using natural language directly on agency websites.

The platform connects with an agency’s property database from multiple sources. It then delivers relevant listings through a conversational interface. Notably, the system supports more than 95 languages.

Moving Beyond Traditional Property Filters

Most European real estate websites still rely on filter-based search systems. Typically, buyers must select options such as location, budget, and number of bedrooms.

However, these filters often fail to capture detailed preferences. As a result, buyers cannot easily express lifestyle needs or specific requirements.

Propelos aims to address this gap. The tool enables buyers to enter detailed queries in plain language. For example, users can search for a "modern villa with sea views and a home office, near an international school, under €2.5M."

The system then matches these inputs with properties listed by the agency. Importantly, all results come from the agency’s own database. This approach keeps users within the agency’s platform and helps capture qualified leads.

First Deployment in Spain

The first live deployment of Propelos is with Costa Sunsets, a luxury real estate agency based in Spain’s Costa del Sol.

The platform currently searches across a portfolio valued at over €2.32 billion. Early usage shows that buyers often include detailed criteria in their queries. These include location-specific references, lifestyle preferences, and architectural styles.

Examples include searches like "apartments under 2m near Aloha school" or "family friendly" and "investment properties."

The AI interprets such inputs and returns relevant listings quickly. Additionally, the system provides agents with full conversation transcripts and records of properties viewed by the buyer.

How the Technology Works

Propelos uses a multi-model AI system. It combines technologies from OpenAI, Google, and Anthropic.

Each model performs a specific task. These include understanding search queries, analysing images, matching listings, and generating responses.

The platform also processes property data from multiple inputs. These include XML feeds, website scraping, and AI-based image analysis.

This is especially useful in the European luxury market. Often, property descriptions are incomplete or available in only one language.

Integration and Setup

Agencies can integrate the tool using a single line of JavaScript. They can also add a dedicated search section to their homepage.

All elements are customisable. This includes design, messaging, and suggested search prompts.

The setup process is designed to be quick. In most cases, the system can go live within 24 hours.

Business Model and Market Focus

Propelos operates on a subscription-based model. Agencies pay a one-time setup fee along with a monthly or annual plan.

Each plan includes a fixed number of leads. Additional leads are charged separately based on usage.

The company does not charge per conversation. Instead, it charges only for qualified leads beyond the plan limit. This aligns pricing with outcomes delivered to agencies.

Currently, Propelos is targeting luxury real estate agencies in Europe. The focus is on agencies with strong digital presence and at least 5,000 monthly website visitors.

Key markets include Costa del Sol, Palma de Mallorca, Madrid, Barcelona, and Ibiza.

Product Roadmap

The platform already includes an analytics dashboard. It tracks session data, search trends, and buyer behaviour.

Next, the company plans to introduce a buyer engagement feature. This will allow users to receive new property listings via email or messaging platforms.

Such features are relevant for luxury real estate. Buyers in this segment often take longer to complete transactions.

Founder Background

Propelos was founded by Mihnea Gamulescu, a Romanian-British entrepreneur based in Marbella.

He previously founded EDEE AI, a SaaS platform focused on digital marketing budget management. The company was acquired by a UK-based group in 2023.

Gamulescu has over 14 years of experience in digital marketing. He has also spent more than five years building B2B SaaS products.

The idea for Propelos came from his own experience while searching for property in Marbella.

"I was searching agency websites the same way people searched for property a decade ago. Filters, dropdowns, scrolling through hundreds of listings. It felt broken," Gamulescu said. "After years managing digital advertising, including for real estate companies and earlier in my career at iProspect, I understood how much agencies invest to get a single visitor to their website. The on-site experience has to deliver. If a buyer can't quickly find properties that match their wish list of features, location and amenities, that investment is wasted. Propelos makes sure it isn't."
