Finance for PE portfolios and tech scale-ups
For operating partners, CEOs and CFOs: we reinforce your finance team or take on the missing leadership. We start with the task that needs to be solved now.
What does your finance team need now?
Finance leadership is missing
A CFO vacancy, transition or temporary leadership need: an interim CFO takes responsibility for the agreed mandate. For ongoing part-time leadership, we assess fractional CFO or CFO as a Service.
Accounting needs reinforcement
A vacancy, backlog or upcoming month-end is stretching your team. Interim accounting supports agreed reconciliations, documentation and closing tasks.
Planning and reporting need work
Actuals are available, but forecasting, variance analysis or investor reporting needs work. FP&A connects operating assumptions with management and shareholder decisions.

Who takes on your mandate?
At nugrow, our own staff and external finance experts work together. Depending on the task, we fill a single role or put together a team. Sebastian Janus personally leads the intro call.
Before the start, we agree who takes on your mandate, what responsibility the person or team carries and what capacity is needed. Deliverables, coordination and handover are part of the agreed assignment too.
Discuss the right staffingHow we start working together
1. Define the task and deadline
We discuss the trigger, existing team, data availability and the next important decision.
2. Agree responsibility and scope
We agree the role, capacity, working arrangements and fees. For interim needs, you receive initial profiles within 24 hours; the start date is agreed afterwards.
3. Review and hand over results
Priorities, owners and verifiable deliverables form the work plan. Documentation and handover are considered from the start.
Start with a practical work template
Finance Assessment → Reporting package → FP&A implementation. Three connected German-language guides with Excel files, from prioritised findings to a repeatable forecasting process.
CLIENT VOICES
What clients say about working with us
Real quotes from founders and managing directors, translated from German (originals on the German page). Some mention ScaleupLab – nugrow's former brand, same team, same company.
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.

TAKE A SHOT
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.
Raphael Fellmer

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.
