Real Estate Agency Lead Generation: Altro & Immowi

Real estate agency lead generation is the process of creating campaigns aimed at attracting prospective buyers, sellers, and renters through strategic marketing. These campaigns are often built around a single moment: a new development launches, a marketing push runs for a few months, and then it's over. Altro Vastgoed needed something fundamentally different.

As one of Belgium's largest real estate agencies — with offices spread across Flanders and Brussels — Altro doesn't have the luxury of thinking in campaigns. Its offices need a continuous, reliable flow of owners willing to sell or rent, buyers and tenants ready to move, investors looking for their next asset, and new-build prospects at every stage of the funnel. Every week. Every month. Year after year.

Finding a partner capable of operating at that scale, across that many audiences, was the real challenge.

The Challenge: Real Estate Agency Lead Generation for a Network, Not Just a Project

Altro Vastgoed has grown into far more than a traditional estate agency. Its business now spans four distinct units: Altro Vastgoed for residential sales and rentals, Altro Projects for new-build developments, Altro Invest for real estate investment guidance, and Altro Home for interior advice. Each unit serves a different audience with different motivations and different decision timelines.

For a single-office agency, generating enough leads is already a full-time job. For a network of this size, the complexity multiplies quickly. A campaign that works well for attracting sellers in one region may fall flat for new-build buyers in another. A message that resonates with investors looks nothing like one aimed at first-time renters.

Altro needed more than a marketing vendor. They needed a partner who could think across all of it — and keep delivering as the business grew.

The Approach: One Partner, Four Business Units, Continuous Optimisation

Since 2019, Immowi has acted as Altro's fixed lead generation partner — not for a single project or a single quarter, but structurally, across the entire group.

The work is built around data-driven targeting and conversion-focused campaigns, tailored individually to each business unit. For Altro Vastgoed, that means generating valuation requests and sales or rental mandates from owners across their office regions.

• For Altro Projects, it means reaching buyers actively considering new-build properties in Flanders and Brussels.
• For Altro Invest, it means identifying investor profiles with the right intent and financial appetite.
• For Altro Home, it means connecting with clients looking for interior guidance alongside their property journey.

What makes this collaboration different from a standard agency relationship is the depth of understanding that builds over time. After more than six years of working together, Immowi has developed a granular picture of how Altro's markets behave — which regions are active, which audiences convert, and where campaigns need to be refined. That institutional knowledge is something no new partner could replicate quickly, and it's what allows campaigns to be continuously improved based on real performance rather than assumptions.

The Results: Scalable, Measurable, and Still Running

The headline number here isn't a single campaign metric — it's the partnership itself. Six-plus years of continuous collaboration is, in the real estate marketing world, genuinely rare. It only happens when the results keep coming.

Across that period, Immowi has consistently delivered valuation requests, sales mandates, rental mandates, new-build leads, and investor profiles to Altro's offices — feeding a network that has continued to grow and diversify its offering. The fact that the partnership has expanded alongside Altro's business units, rather than being replaced as the agency evolved, is itself a measure of what's working.

Altro today holds a position among the top 10 real estate brokers in Belgium — a standing built not just on the quality of its agents, but on a steady pipeline of qualified opportunities reaching those agents every day.

What This Means for Real Estate Agencies Like Yours

The conventional assumption in property marketing is that lead generation is a developer's tool — useful when you have a specific project to sell, less relevant for a broker managing ongoing sales and rental activity. Altro's story challenges that assumption directly.

If you run a real estate agency — whether a single office or a growing network — and you're relying on referrals, portals, and ad hoc marketing to keep your pipeline full, there's a more structured way to think about it. Consistent, data-driven lead generation, built around your specific audiences and regions, can work just as well for brokers as it does for developers.
