What They Do
Deftpower B.V. is a private cleantech startup focused on developing software for integrating renewable energy sources such as solar and wind energy into electric vehicle (EV) charging. Their technology includes an AI-supported SaaS platform and a white-label mobile application that enables smart charging, allowing vehicles to connect with networks, energy markets, and over 2,000 charging point operators across Europe. This allows them to reduce costs by up to 20% through dynamic pricing and prepare for vehicle-to-grid (V2G) functionality (source: cbinsights.com). Deftpower serves a wide range of clients, including e-mobility service providers, charging point operators, car manufacturers, energy suppliers, and grid operators, and has a platform that processes millions of transactions in 10 European countries (source: deftpower.com). Their products include a branded app for drivers that provides access to over 800,000 charging points, a business portal for electricity trading and fraud prevention, and developer APIs compatible with OCPI and ISO15118 protocols (source: deftpower.com).
Projects & Track Record
Deftpower has built an impressive track record by implementing its platform for over 40 clients managing widespread EV charging solutions. A notable project is the ongoing smart charging trial launched on May 15, 2025, in Amsterdam, designed as a potential model for global cities by optimizing grid load and renewable integration (source: cbinsights.com). Collaboration with over 40 EV brands and 2,000+ charging point operators strengthens their market position, although specific client names have not been disclosed (source: deftpower.com). Deftpower's platform is active in 10 European countries, focusing on expansion funded by their recent €12.5 million funding round (source: 4impact.vc).
Recent Developments
In the past two years, Deftpower secured €12.5 million in funding on August 29, 2025, led by Endeit Capital with participation from 4impact capital, Proeza Ventures, Rethink Mobility, and Jan Fredriks, supported by the EU's InvestEU Fund. This funding is intended to drive European expansion and AI enhancements for their platform (source: 4impact.vc). The Amsterdam smart charging trial, which began on May 15, 2025, marks a significant milestone in the practical implementation of their technology (source: cbinsights.com). So far, no acquisitions, mergers, awards, or additional certifications have been reported in the sources from 2024-2025, although CEO Jacob van Zonneveld's previous role in founding Plugsurfing (acquired by Fortum in 2018) highlights the continuity of leadership (source: vehicle-2-grid.eu).
Working at Deftpower
Deftpower currently has approximately 70 employees, growing from just over 50 previously. Roles include software development (API and backend for EV integrations), product management, sales, business development, customer service, and operations within engineering, IT, and cleantech functions in an agile team structure (source: 4impact.vc). The company has offices in Arnhem and Berlin, focusing on growth in EV software amid European expansion (source: deftpower.com). The company culture emphasizes technical excellence, rapid execution, and creating clarity from the chaos of the industry, with values aimed at stakeholder success, both economically and ecologically (source: deftpower.com). Specific benefits are not documented in public sources.

Job Description
At Deftpower, we're shaping the future of electric charging every single day. Our SaaS-platform helps businesses across Europe make charging simpler, smarter and more sustainable. With AI and intelligent software, we make sure charging works seamlessly with the energy grid, creating a greener and more stable system for everyone.
We're growing fast, thanks to a recent major investment, and there's never a dull moment! We're expanding, improving our technology. We hope our team of 85 grows to 125 by the end of this year!
About the team
The Sales team at Deftpower sits at the heart of our commercial growth. Led by Nicholas, our CCO. The team works closely with Business Development, Sales Managers and Customer Engagement to turn complex eMobility challenges into long term client partnerships. There are around 10 people working in this team divided over Berlin and Arnhem.
We operate in an international B2B environment where every deal is different. As a white label platform, our success depends on deeply understanding our clients' business models and helping them succeed in their own markets. That means sales at Deftpower is consultative, content driven and highly collaborative. Trust, clarity and long term value always come before short term wins.
About the job
Your work is about turning existing clients into long term fans of Deftpower. You step in when Sales moves towards the contract phase and become the trusted sparring partner who helps clients grow beyond the initial deal. You quickly understand their strategy and challenges and make sure the right people inside Deftpower are involved at the right time.
- You show clients what they didn't know was possible. By connecting their ambitions to everything Deftpower has to offer, you help them get more value out of our products and make the next contract a logical and enthusiastic yes.
- Join the sales process from the contract phase onwards and build strong, lasting client relationships
- Work closely with the CET team during onboarding, migrations and follow up projects, keeping expectations sharp and delivery on track
- Turn client feedback into concrete upsell, cross sell and product improvement proposals
- Handle renewals and negotiations together with internal stakeholders and represent Deftpower towards clients and at industry events
For you

Colleagues describe Deftpower as ambitious, open and energetic, with enough movement and change to keep things exciting. We are growing fast, learning as we go and improving every step of the way.
You work closely with experienced colleagues and a management team that is approachable and involved. You get the space to take ownership, make real commercial decisions and try things out. Sometimes that works immediately, sometimes it doesn't. That is part of how we learn and grow as a team.
This role comes with a lot of time on the road. You visit clients, attend industry events and trade fairs across your region and Europe. Every quarter we bring everyone together in Arnhem for our Deftpower D Day. A full day with all colleagues, followed by good food, drinks and the kind of legendary stories and jokes you only get in a sales team that knows each other well.
- Salary range between ???70.000 and ???80.000 per year, depending on experience.
- Holiday allowance and vacation days in line with local regulations.
- Pension and long term benefits arranged according to local standards.
- ???2.000 training budget per year to keep learning and growing.
- Choose your own laptop to work with, up to ???1.750.
- A flexible setup with hybrid working, short decision lines and a high level of trust.
About you
This role is for people who like responsibility, enjoy working across disciplines and want to help shape how Deftpower grows across Europe. You have space to influence how we sell, how we position our value and how we build sustainable, long term relationships in a fast growing and evolving market.
- You have a proven track record in B2B key account management, preferably in a SaaS environment.
- You enjoy going deep with customers and feel a strong drive to improve their daily operations and long term success.
