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!

I really enjoyed the workshop with you and many of my TU Wien Innovation Incubation Center pals the other day! Honestly one of the best workshops I have ever attended and probably with much more interaction from all sides compared to some offline workshops.

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.”

I run the Vienna Business Agency’s “Founders Lab” programme, during which I provide intensive support to early-stage start-ups over three months. Workshops and coaching sessions with Konsultori are a central part of the programme. The founders, regardless of their industry, benefit enormously from Petra’s, Franziska’s and Joachim’s input on the topics of business modelling, finance, negotiations and investments. Konsultori’s wealth of experience, expertise and approachability is a great asset to the startup ecosystem in Vienna.

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.

I enjoyed the workshop on customer acquisition measures for civil engineers so much that we are now going to get the whole office on board to implement the measures. The practical examples are motivating and show how customer acquisition can be strengthened on several channels – and that acquisition is something that can be learnt! Highly recommended.

The workshop “Marketing and Acquisition for Creative Professionals” was a great success. Petra’s competent, goal-oriented way of giving feedback, analysing problems in start-ups precisely and quickly and providing practical examples as comparative values, combined with an interactive, “creative” workshop leadership made the event very exciting and definitely recommendable.

Petra used her wealth of B2B negotiating experience to help our lab companies find ways to grow and share the pie with Arsenal. Based on the relationships they’d developed with the business owners, and the quality of their offers, half the companies reached agreements to enter commercial pilots. That speaks volumes for Petra’s value.
