A selection of what our satisfied clients have to say
Working with Scaleuplab (now nugrow), and Sebastian Janus in particular, allowed us to take our pitch deck and financial plan to a much more professional level. Thanks to his experience in SaaS, we were able to approach investors quickly and in a targeted way. Everyone at Scaleuplab was always available, and at the same time we got a very good picture of how the startup world works.
We have tackled several projects together with Sebastian and his team and have been working together since mid-2021. For medium- to long-term financial planning to optimise our business model, we brought in support for our financing documents and strategy, as well as for our pitch deck. Sebastian helped us with advice and hands-on work to make our financial planning more concrete, which supports our long-term strategic direction. We were also able to improve our EBIT. We can highly recommend working with Sebastian & nugrow.
Together with Sebastian Janus and ScaleupLab (now nugrow), we developed our first professional financial plan. Their extensive experience with digital business models and e-commerce helped us a great deal. Sebastian Janus's team works very professionally and fast. Important questions and changes afterwards are handled openly and quickly too, which is not a given. More than a year later, we are still in close contact with the team and can give a clear recommendation.
Whether directly as CFO or as an adviser, Sebastian is a positive and proactive partner who really helped me. He finds the right approach for every startup and knows how best to put it into practice. I can only recommend him.
With his entrepreneurial background, Sebastian is a true expert and an experienced sparring partner in financial planning. His experience with tools is just as helpful as his DATEV knowledge and his understanding of what matters in investor conversations. Sebastian works as an equal and is always there with advice and support. What I also value highly: Sebastian gets to the point quickly and delivers very reliably.
Together with Sebastian I created a pitch deck that convinced investors, which got us over the first startup hurdle straight away. Working together was straightforward and competent: Sebastian has plenty of his own experience from the founder scene and many resources he shared with us. I would definitely recommend him!
Raising capital for the first time as a first-time founder is a huge challenge. What I valued about Sebastian's advice is that it is focused and gets straight to the point, and that you can also clarify detailed questions, not just get "general advice"!
We got to know Sebastian through the German Startups Association (Bundesverband Deutsche Startups). Working with Sebastian was personal and built on trust from the very start. We worked with him on our pitch deck and our financial planning, which helped us enormously. We can absolutely recommend Sebastian and his team as professional contacts and startup coaches.
We experienced Scaleup (now nugrow) as a young, creative, professional, always reachable and reliable team that thinks along with you. A collaboration we can only recommend.
Sebastian offers top-class advice specifically for startups and always had the right resources to hand for me. He knows what a good pitch looks like, how to find the right investors and how to scale successfully. I can only recommend him.
Sebastian helped us prepare our first funding round. He warned us about common mistakes, recommended valuable tools and connected us with the right people. We can absolutely recommend Sebastian and Scaleuplab (now nugrow).
