Trayan HristovFounder & CEO

Trayan leads Thrivelia’s retention and lifecycle strategy, helping DTC brands connect customer insight with email, SMS and repeat-purchase growth. His work brings together commercial analysis, customer journeys and creative execution.

What Sets Us Apart

Strategy built around the customer lifecycle

We use customer research, purchase behaviour and lifecycle analysis to connect acquisition, conversion, repeat purchase and reactivation. Our Hourglass approach helps identify what to build, test and improve across the journey.

Strategy, creative and execution together

Lifecycle strategy, copy, design, platform implementation, deliverability and reporting work together. We build and improve campaigns and automated journeys, then use results and customer insight to guide the next round of work.

Commercial measurement beyond opens and clicks

We assess repeat purchase, customer value, campaign and flow performance alongside engagement and deliverability. Case studies identify reporting periods and distinguish platform-attributed revenue from proven incremental lift.
