Specialist profile

Tatiana Korostyleva

Chief Marketing Officer (CMO)

Tatiana Korostyleva is a co-founder and the Marketing Director of Undersun Estate. With 6 years in digital marketing and over 5 years in Phuket real estate marketing, she built the company's marketing and sales system from scratch — from client acquisition to the technical setup of the sales department. Tatiana holds a degree in organisational management, and that systematic mindset shows in how she runs marketing. She has 6 years in digital — building performance campaigns and automated sales funnels in which every stage, from first touch to enquiry, is measurable and tied to conversion. It's a discipline where every unit of budget works toward results, not reach for its own sake. For more than 5 years Tatiana has worked in Phuket real estate marketing and knows the island's market from the inside — its properties, developers and price dynamics from the pre-Covid and Covid periods onward. It's a market with its own rules: a long deal cycle, high price points, an international audience, and trust as the main currency. At Undersun Estate she owns not only client acquisition but the technical infrastructure of sales: full CRM setup and automation, integrations with lead sources and communication channels, and a funnel built so that no lead is lost between marketing and the deal. As a co-founder, she also shapes how the brand sounds across every channel, from Telegram to premium platforms.
