Tiina Wilen is the creator of Avenue Growth System™ & the CEO of Avenue. She and her team help growth-focused business owners build assets, systems, and infrastructure required for sustainable business growth.

Tiina holds a Master of Science in IT Engineering, a Bachelor in Business, a certificate in Client Acquisition, and a Diploma in Interior Design.

Tiina works as a growth coach for several successful small businesses and occasionally as a fractional CMO/CGO for design brands that scale beyond the 2-5 Million EUR mark.

With a solid corporate background in IT and finance, travel, hospitality, and design, she has worked as a CEO, IT & management consultant, project manager, business developer, and process manager with responsibility for multi-million EUR offshore operations and a global team of 300+ software engineers, global manufacturing & shipping processes and international sales and partnerships.

She and her team help professionals and product brands in the design/wellness/lifestyle industries create concepts, products, services, and brands that become the industry leaders, scale past their current capacity with the right infrastructure, and expand to international markets. She also invests in digital assets and owns several services, media & publishing B2B and B2C brands.

Her favorite hobby is home decor and she tends to redecorate a lot. Tiina doesn’t cook; luckily she married a guy who does, and her secret superpower is wallpapering.

Born in Helsinki, Finland, Tiina is a mother of 2 and the Wilén family lives a harmonious small kids life in the Swedish countryside with their Staffie pup Franklin.

She believes building a business should be fun. She also believes implementing assets, systems and processes is the only way to really grow and scale a great business. Lastly, she believes growth – business and personal – is a choice.
