Bootstrapping

As non technical co-founders of an online marketplace, my colleague and I found ways to: - string together off-the-shelf products to test hypotheses - find low cost resources to fill gaps while we focused on sales - prioritize and strip back all non-essentials I'd be happy to share my bootstrapping journey and provide some ideas about ways you can do more with less.


Growth marketing

Data, data, data. It's all growth comes down to. Focusing on collecting information from customers and potential customers, and prioritizing BI tools early in your companies trajectory will help you avoid some of the early pitfalls I've encountered!


Advice on funding

I've had experience raising four rounds of Venture Capital; three as a Co-Founder and one as Head of Research & Strategy. I'd be happy to share my funding philosophy, why we decided to fundraise after years bootstrapping, and things to look out for as you begin the journey to accelerate your companies growth.


Product market fit

My background is in market research and marketing strategy. This stood me in good stead to take an insights driven approach to finding product market fit. I'm of the strong opinion there's no better way to find product market fit than to speak with customers and potential customers. To get the most out of these conversations, a solid research plan is needed. This is where I can help!

Harri was an excepcional mentor! He asked for more details of my case to have a better understanding about it days before of the session. During the session not only was he giving concrete advices to improve the results of the tests I was driving, he also encouraged me to follow alternative ways to reach my potential clients, that based on his real life experience, proved to be more effective. If you are facing challenges or feel you need to learn more about marketplaces, Harri is your mentor!

Harri is a gifted and patient listener who made me feel at ease right away. He understands the particular challenges that come with bootstrapping. His mentorship on how to validate my idea while also generating revenue was a match for where I am now in my business.

Harri is a scrappy entrepreneur who started from literally nothing and no money and built a terrific startup with his team. And I feel like I got a front-row seat with regards to some of the high-level analysis and the pivots and the thought processes that went into the company's origin and its strong growth. He is specific with his insights and he is very encouraging to the entrepreneur and our focus on preserving capital and saving time while executing on our mission to bring valued services to paying customers. He truly knows his stuff and he loves building businesses and helping others who are doing the same.

My session with Harri was excellent. He took the time to learn about my business model and market before giving any advice. He offered recommendations based on his experience but also an objective analysis of where he thinks we should adjust our thinking. The biggest takeaway, was that he helped me reign in our roadmap and realign our milestones based on the metrics that should matter, like getting active users and our first dollar of revenue in the door. Our call was only 30 min, but was packed with so many insights. If I were to read or scour Youtube for the same advice it may have taken hours. 5/5 experience overall. Highly recommended.
