We are on a mission to help Visionary Leaders, Entrepreneurs and SME CEOs grow profits, impact and joy.

However, what often keeps us from hitting our financial, impact and lifestyle goals is confusion around what we're supposed to do next to grow our companies. 

The Internet is full of great tips, yet most small business owners struggle. Why?

Because nobody is handing a MAP that is tailored for her specific needs, tailored to understand how the different growth activities: sales, marketing, social media, branding, tools, product development, delegation, financial planning, advertising, webinars, SEO, publicity, partnerships... how they actually fit together and when is the right time to focus on the specific activities. 

For years, I and my team at Avenue Strategy Group have been on a mission to end confusion, and we have successfully helped thousands of entrepreneurs, business owners, CEOs of small and mid-sized companies, experts, coaches, consultants, agency owners, product designers, and online business owners to get clarity, create a solid plan and focus on the right activities at the right time to increase their profits, impact and joy.

This system has previously only been available for our private clients, but since we know that right now confusion is bigger than ever, I decided to teach this system to as many as possible, to help them finally get their growth engines going. 

Join me for this on-demand workshop and let's get clarity, make a solid plan and grow your business together!

Best, Tiina Wilen

Creator of Avenue Growth System™ | CEO of Avenue Strategy Group 

Also: a Finn, Mama of 2, Systems Engineer, Business Model Specialist, Investor, IP & Growth Coach to Ambitious Business Owners. 

Tiina Wilen is one of Europe’s leading experts in helping professionals and small business owners package their skills, experiences, passion, and knowledge into intellectual property, products and services that sell at scale, and building the solid infrastructure a growing company needs.

Tiina holds a Master of Science in Systems Engineering & Bachelor in Business and she spent nearly 15 years in the corporate world as an IT & Management Consultant, Product Manager, and Global Process Manager, where she was responsible for multi-million euro offshore operations and delivery performance leading global teams of over 300 software engineers. She has worked as a CEO managing international brand launches, manufacturing, and distribution processes, and is now the CEO of Avenue Strategy Group; the leading growth engineering company in Europe offering coaching, consulting and education for SMEs. She also owns several international B2B & B2C brands, and manages to grow all her assets while spending a lot of quality time with her kids, husband, and animals.

These experiences taught her that assets, systems, and processes create profits and freedom. After launching her first business in the home textile industry, Tiina saw that many small business owners lack solid systems that allow big companies to scale. Tiina and her team are now on a mission to grow profits, impact and joy for small business owners. 

It's time we remove confusion once and for all. 

Growing a profitable company with lots of free time can be simple & enjoyable if you know what you should be focusing on next.

A tiny percentage of small business owners manage to grow their companies and enjoy life while the majority of their peers are stressed, overworked and overwhelmed. There's one thing they do right from start, and I'm here to share this GROWTH ACTIVATOR with you.

What others say

I have long experience as a manager, and have also run my company for several years. Even as an experienced manager you sometimes get stuck, and especially if you are an entrepreneur with your own company.

It's good to have someone outside who can coach you forward. If you have long experience yourself, it is even more important to find a coach who understands your situation and can coach you at the right level. Then it's not about having the support of someone who knows your brand, it's about finding a professional for strategies and models, ideas, and inspiration to lead me forward in my business.
Finding the right person for this is important, as you as an entrepreneur invest your time and money.
For four months I have hired Tiina as my private coach, and this has been well invested money. Tiina has quickly understood my situation, and guided me forward to feel good and able to lead my company forward. She has motivated and given me tips, she has inspired, and expected results. These four months have been much needed for me, I have regained the joy of running my successful business even longer. "Sky is the limit and Tiina helps you get there"
Mariana Ramselius
CEO at Silander Holst S.L
Being in business for years I have learned the priceless value of having a mentor who had knowledge proven by own results and passion to share it with those who are willing to learn. For over a decade I have been building multiple businesses representing other companies, but never broke through to the level I longed for. Tiina Wilén played the main role in both helping me identify my main calling and values I can give to others and helped me building my own brand from the scratch.
The combination of her always up to date knowledge, method, patience, passion and just wonderful personality gave me faith and courage to learn and do things I never thought I could do. By the results I’ve got right from the start launching my company I can boldly declare that Tiina is a top professional in her business niche. I am forever thankful.

I have attended a lot of different educations during my time as a business leader. What Tiina does with the Avenue Program is that it connects the dots to make the picture complete. This is unique. I’m really excited to see how our results will improve in the future.
Barbro Axelsson

I can highly recommend Tiina and Avenue. The program and the energy gave me the power to improve and walk further out of my comfort zone, made me more digital and crossed new boundaries. It was a pleasure and great business opportunity to work in her program.
