Meet Lenah
the World’s First AI Property Guru

Your Property Guru & Personal Assistant - Reinvented with Breakthrough AI.

Hi, I’m Lenah, PropMarker’s AI property guru.

I read floorplans, analyse the market in real time, and turn overwhelming data into clear, confident decisions. I understand sold prices, planning activity, EPC patterns, neighbourhood signals and emerging trends - and I keep learning every day. I learn from experienced investors, developers and analysts, and I stay tuned to market shifts, planning updates and policy changes that affect real opportunities.

I may not be perfect, but I’ll always show my reasoning, highlight uncertainty, and improve with every question you ask.

Powered by PropMarker’s vast intelligence network - over 900,000 live listings, 16 million sold records, 34 million EPCs, and 200 million land and planning datapoints. I can uncover genuine potential, spot undervalued deals, track price movement, predict demand, and reveal opportunities that others overlook. I’m not here to replace your instinct - I’m here to amplify it with clarity, evidence and precision. If you rely on outdated tools, you’ll miss tomorrow’s opportunities.

I’m Lenah - the AI that thinks like an investor, learns like a human, and helps you see what others can’t.

After two years of engineering, refining and imagining.
PropMarker proudly introduces Lenah the world’s first AI Property Guru.
She is the result of late nights, hundreds of datasets, thousands of tests and the shared vision of experts who believed property investing should be simpler, faster and smarter.

The Story Behind Lenah

It all began with a simple question:

Can technology think like an experienced property investor? That question united two founders from different worlds.

Milton Rodosthenous

Milton Rodosthenous,
A UK property entrepreneur with decades of experience and a £300M+ portfolio, known for spotting value where others saw just another listing.

Roys Kalarikkan

Roys Kalarikkan,
A technology entrepreneur with over 20 years of experience delivering digital transformation, driven by AI, data and innovation to solve real-world problems.

Together, they set out to merge human expertise with artificial intelligence, giving birth to Lenah, the world’s first AI Property Guru.

Built by a dedicated team of 20 specialists, from AI engineers to UX designers. Lenah was trained to think like an investor, analyse like an expert, and guide like a mentor. She doesn’t just read numbers; she interprets patterns and turns complexity into clarity.

“We didn’t just build an algorithm, we built a property mind.”

Milton Rodosthenous & Roys Kalarikkan
Co-Founders of PropMarker
