Not too long ago, in a very focused coaching session with Petra Wolkenstein Konsultori, we made plans to blaze new trails and look for innovative ways to take Wristbanditz to the glamorous, international places they belong (a.k.a. work on my weak point and substantially improve the sales process). The result is glamorous: an affiliate partnership collaboration with Cvent – the industry leader in event technology.

Konsultori and Petra Wolkenstein are extremely professional. Her experience really helped us to get through the first funding round. We were thrilled that the documents and arguments which we produced in the preparations stage were so well received in our search for investors and during negotiations. I appreciated such a straightforward, hassle-free and honest partner who never forgot our goals and timeline. Without Konsultori, we’d never have managed to achieve everything within such a short space of time.

Above all, the collaboration is reliable. That’s exactly what you need at the beginning: reliable partners who are there for you regularly and provide constant support. It also feels trusting and not like “off-the-peg counselling”.

Thank you a lot for the session this week! Some of the feedback from the founders (NPS 100!): The practical approach. Petra was super useful and clear and knowledgeable. The practical exercise super useful points for the negotiations. The combination of theory and practice. Even though we only learned about term sheets the negotiation practice was very useful and, in fact, helped us understand terms sheets better. The exercise was really interesting and a good insight into negotiation practice. It has been really great the best exercise I’ve done in the startup world!

Thank you Petra! I want to share the comments received from the founders on the feedback form: “Amazing lesson should be a must for any founder, and life in general.It was really useful from a practical standpoint, clearly and helpfully delivered and felt like a safe space to learn, make mistakes, grow better. This is really great, would love to have more practice on this topic, and so I am going to make sure I use any materials available to work on it more.Great session. ! I don’t like role plays so was dreading it, but that was very useful. Thank you! The practice part was very cool a bit more of „hardcore“ examples and tactics, seemed too nice! Interesting topic I was expecting to get to go more in depth of special techniques of negotiation, maybe doing the simulation after the explanation of techniques so that you can apply. Liked all of it! The interactive element was strong and really enjoyable.”

Our collaboration with Petra has been a privilege, and without hesitation, we attest to her skills as a mentor and industry expert. Given Grayn’s position as an innovative technology company, with a focus on both environmental and social impact data, Petra’s guidance has played a pivotal role in navigating the intricacies of our expansion into the DACH region, specifically Austria. By leveraging our carefully crafted sales and market expansion strategy, Grayn achieved a heightened level of efficiency and success in penetrating the Austrian market. Petra’s expertise played a vital role in this accomplishment, allowing us to navigate the complexities of the local business landscape with confidence and precision. As a result, we were able to establish a strong foothold and make significant progress in our mission to promote sustainable accounting practices in Austria.

I was able to enjoy another great workshop at i2c last week. Petra Wolkenstein shared her knowledge on B2B negotiations with us. My personal highlight was a role-play we did. We formed teams of two-each person representing one of two parties- with the task to negotiate a deal. The scenario was about a scientist and a corporate that had to agree upon IP-rights so that they could bring a new product to the market. If successful, the deal would yield increased revenues to both, but they had different expectations towards the success chance of the project.

Our incubatees raised their negotiation skills for B2B Sales & Partnering to the next level with the help of our negotiations expert Petra Wolkenstein.
