CASE
P2X Solutions needed a competent resource at short notice to cover the Business Controller role during the recruitment process. The situation was further complicated by an ongoing intensive financing round.
SOLUTION
NIS quickly appointed Interim Controller Riikka to handle the Business Controller responsibilities and support the CFO during the financing round. With her help, the financing round was successfully completed, reporting was adapted to the new majority owner’s requirements, and continuity in the finance function was ensured despite the changes.
Interim Controller support during P2X Solutions’ financing round
When P2X Solutions’ Business Controller moved on to new responsibilities, the company quickly needed a competent replacement to cover the role during the recruitment process. At the same time, the finance team was challenged by a rapidly changing environment, as an intensive financing round was underway. With the help of an Interim Controller, the finance team successfully navigated a period marked by significant change.
Interim Controller eased the CFO’s workload during financing
P2X Solutions is a startup building Finland’s first industrial-scale green hydrogen production facility in Harjavalta. The finance team consists of two people: a CFO and a Business Controller.
When the Business Controller left for new opportunities, the role was temporarily taken over by NIS consultant Riikka Vuorenoja. Riikka was responsible for standard BC tasks such as profitability calculations for upcoming investments, developing internal cost accounting for the future production facility, and reporting to various stakeholders. In addition, she supported the CFO during the financing round and handled associated operational tasks, freeing up time for the CFO to focus on higher-level priorities.
NIS interim consultants are used to quickly taking on new responsibilities. Thanks to Riikka’s expertise and background as an auditor, the company chose to retain her not only during the initial short-term recruitment period but throughout the entire financing process. The intensive financing round required flexibility and exceptional working hours from the Interim Controller to ensure high-quality deliverables were provided to investors on time.
Interim solution adapting to a changing environment
As a result of the financing round, Swiss energy group Alpiq became the majority owner of P2X Solutions, enabling further growth and the construction of new production facilities. Interim Controller Riikka supported the integration of monthly financial reporting into Alpiq’s systems and helped implement group guidelines, for example in accounting for investments.
During this transition phase, continuity in the finance function and retention of knowledge were critical, as the Harjavalta plant was nearing completion and the CFO role also changed.
As circumstances evolved, P2X Solutions chose to extend Riikka’s assignment to more than a year, and before completion she will also onboard her successor.
“Using an interim solution gave us additional resources in a flexible way and at short notice. Riikka, who stepped into the role of Business Controller from NIS, is a flexible and meticulous professional, and her expertise was a perfect fit for our company. We were therefore happy to retain her for a longer period,” comments CFO Olli Muurikainen, who joined P2X Solutions in August 2024.
Time and expertise for the finance team through interim support
An interim consultant brings expertise into the organisation and frees up time for other team members. Riikka describes her experience at P2X Solutions as follows:
“The work was very interesting, as you do not often experience a financing round in a startup environment. The assignment was highly relevant and motivating, as P2X Solutions is building the green hydrogen market in Finland. In a startup, roles and responsibilities are flexible, which allowed me to learn new things and apply my skills broadly.”
NIS finance professionals can step into a new role within just a few days. In changing situations, assignments can easily be extended when needed, without long-term commitments. NIS also provides specialised expertise for different needs, ensuring companies get the right person with the right background for each role.
