It was a really good day – intense, clear, motivating. Now we will continue on this path together. A big thank you to Petra Wolkenstein, who guided us through the day.

We are delighted that VeLuMe is one of eight startups selected to participate in this fantastic mentoring workshop organised by the Vienna Business Agency! A big thank you to the team behind Growth Lab – Martin Wolf, Gregor-Robert Posch, Franziska Kolk and Konsultori – for giving us this opportunity, providing us with room to grow and sharing their expertise with us.

Today I kicked off my financial coaching journey with the incredible Petra Wolkenstein. Petra has this rare mix of crazy deep expertise, patience, and clarity that makes complex financial topics feel approachable and even exciting. She doesn’t just help with numbers — she helps you see the bigger picture of your mission and how to make it truly sustainable. I truly think she is the best out there in Vienna right now! 🚀

Petra has been an instrumental part of Howie from the very early days. What began as temporary executive coaching to support me through the challenges of solopreneurship evolved into a trusted, ongoing partnership over the past two years as we scaled the company. Her clarity, structure, and ability to cut through complexity have been invaluable during high-growth and high-pressure phases. In addition, Petra played a key role in shaping our financial strategy and developing a robust financial plan to support our VC financing round. I’m deeply grateful for her steady guidance and would highly recommend her to any founder navigating a complex journey of building a company.

We value the insights and knowledge that the amazing Konsultori experts have shared with us. Their guidance is helping us grow faster and smarter.
A special thank you to Petra Wolkenstein, whose support and mentorship inspire us to think bigger and tackle challenges with confidence. Her guidance is already making a real difference in how we shape our growth journey.

We won! Yesterday, MINTorin was selected as one of four winning ideas at the European Forum Alpbach Pitch Session in the Climate Track. I’m incredibly thankful to Franziska Kolk, who coached me via Wirtschaftsagentur Wien and helped me bring out the best in this pitch.
This is also your win!

Right now, I’m in the process of figuring out the right strategy to help my business continue to grow and thrive. The financial overview I created with Petra Wolkenstein from Konsultori is a great help in this regard. Because if I don’t have my finances under control, I can’t develop a strategy, let alone adapt it to the situation.

We decided to work closely with Konsultori to implement the sale of our company strategically, and that was the right decision. Petra Wolkenstein guided us through the various phases of the process with her experience, clear structure, and in-depth M&A expertise. Her input helped us prepare important negotiation steps in a targeted manner and sharpen our positioning in line with our strategic goals. The structured development of a convincing deal framework – including financial data, narrative, and argumentation – as well as the targeted preparation for critical discussions with potential buyers, was particularly valuable. As the founding team, we were able to consistently implement our strategy while benefiting from Konsultori’s sound external perspective and methodological certainty. Startups that want to approach their exit in a well-founded manner will find Konsultori an excellent choice.

Adding more value to the day, Konsultori’s power-packed session on Scaling Readiness of startups was another meaningful & strategic event. Goal setting with OKRs, participatory leadership, employer branding, employee experience, employer & employee value proposition, people & culture readiness, hierarchy, operations readiness, go-to-market readiness and the smart RICE FACTOR engagement – REACH, IMPACT, CONFIDENCE & EFFORT. We shared a beautiful, interactive moment at ViennaUP, where our goals are aligned.
