Din Bisevac was once a YouTube child star. At 26, he just pulled off a $58 million comeback, rescuing a failing real estate startup and convincing Google Ventures to lead its Series A round.

Buena, the Berlin-based property technology startup Bisevac now leads, has attracted backing from top investors including Google Ventures, 20VC, Stride, and Capnamic. The fresh $58 million Series A raise Buena announced on July 23 marks a turning point for the company after years of struggling under its original business model. The raise marks the startup's first funding round since Bisevac took over in 2021 and pivoted the business from a failed rental arbitrage model, reports.

Buena had previously burned through $14 million while attempting to lease apartments below market rates and rent them out for a profit, a strategy that ultimately stalled growth. According to reports, Bisevac restructured the company, negotiated new terms with investors, and repositioned Buena as an AI-powered property management platform.

Buena manages more than 60,000 apartments across Germany, and reports say it has achieved roughly $25 million in annual recurring revenue, a sign of rapid post-pivot growth. Buena says it automates property listings, tenant vetting, viewings, and maintenance coordination through its software, which also integrates new AI features to handle repetitive accounting and reporting tasks.

Alongside software development, Buena has pursued an AI-led rollup strategy, acquiring over 20 property management firms since 2023 in a fragmented German market valued at approximately €16 billion, or $17 billion. According to Buena, the property management sector in Germany is notorious for inefficiency, with 96.3% of managers still using outdated systems and struggling with low customer satisfaction scores.

“Property management just has a terrible, terrible brand in Germany. No matter which owner or tenant you ask, everyone will tell you they hate their property manager,” Bisevac told reports. “We wouldn't position ourselves as this mainly technology company in front of our customers because it’s a bit too abstract for them, and frankly just doesn’t matter too much.”

Google Ventures Partner Vidu Shanmugarajah said in Buena’s statement that the startup’s mix of an AI-driven acquisition strategy and product-focused execution creates a strong opportunity to modernize property management globally.

“ healing is just the start, and we look forward to supporting Buena in changing how people own real estate across Germany and beyond,” Shanmugarajah added.

Buena says it intends to expand across Germany and then into the U.S. housing market, which is valued at around $50 trillion, offering significant growth potential.

According to reports, Bisevac's long-term vision is to build an end-to-end platform for real estate investment, allowing individuals to find, finance, purchase, and manage properties within one ecosystem. The goal is to make property ownership more accessible to younger generations, who often invest in stocks and crypto but lack clear pathways to real estate investment.

Din Bisevac's entrepreneurial journey began long before Buena's turnaround. As one of Germany's first YouTube child stars, he launched a clothing brand and Shopify SHOP store before working as a product designer at age 13, reports say. After joining Buena as a designer, he rose to CEO, leading the restructuring that attracted high-profile investors.

The Series A funding underscores the growing investor interest in AI-enabled service industry rollups, a strategy gaining traction among private equity and venture funds worldwide. With fresh capital, an AI-powered strategy, and a vision for property ownership, Buena is preparing to expand far beyond Germany.
