Open Immo

Context & Challenge

Open Immo is a collaborative real estate platform built to modernize how real estate agents manage, share, and co-broker property listings. Designed as a progressive web app, the platform centralizes mandates, simplifies agent collaboration, and tracks performance across customizable dashboards.

The core challenge was to design and manage the development of a fully scalable product from the ground up, ensuring that:

• The interface respected real estate industry codes while introducing a fresh, modern design language,

• The brand identity was clear, cohesive, and visible throughout the entire platform,

• The UX remained simple for new users but powerful enough for expert agents,

• A flexible and interactive KPI dashboard could support data-driven decisions.

Approach & Execution

Eric Sisounthone led the project from strategy to design and delivery. His dual role as Project Manager and Lead UX/UI Designer allowed him to ensure alignment between design, technical constraints, and business goals at every stage.

His contributions included:

• Creation of the full visual identity: logo, brand guidelines, typography, and color system tailored to a premium and trustworthy real estate environment.

• Design of a custom UI kit and scalable design system in Figma, ensuring visual consistency across mobile and desktop.

• Definition of all user journeys: onboarding, authentication, mandate sharing, internal messaging, and dashboard flows.

• Management of the product roadmap, backlog, and timeline, coordinating between developers and stakeholders to guarantee smooth delivery.

Special attention was given to the dashboard experience. KPIs were segmented by role (agent or admin), with modular components that allow users to filter by time, property type, or region—making insights easy to interpret at a glance.

Impact & Deliverables

The result is a modern SaaS platform that blends tech performance, intuitive UX, and a strong visual identity—all while respecting the codes of the real estate industry.

Open Immo now stands as a forward-thinking real estate platform, empowering agents with tools to collaborate, analyze, and grow — through a digital experience designed for clarity, efficiency, and trust.
