Head of Sales (m/f/x)
atmio • Germany
Posted: January 23, 2026
Job Description
atmio is a climate tech startup founded by second time founders who have built and scaled companies before — and we’re doing it again, this time for one of the hardest and most impactful problems out there: reducing emissions of the energy sector.
We’re backed by top-tier VCs and supported by an exceptional group of angel investors and operators who’ve scaled category-defining companies across Europe and beyond.
Our customers include leading German operators of critical energy infrastructure who rely on atmio’s AI-powered hardware + software platform to make methane emissions visible, measurable, and most important reducible.
We already have customers, revenue, and momentum. Now we’re looking for a Head of Sales who’s been a few chapters ahead — someone who has scaled from early traction to €10M+ ARR and knows what’s coming next.
🎯 What You’ll Do
- Own revenue growth end-to-end. From pipeline to forecast to closing — the numbers are yours.
- Scale what already works. Take early traction and turn it into a structured, repeatable sales motion.
- Lead and grow the sales team. Coach our small team and hire the next wave as we scale.
- Be hands-on where it matters. You’ll still close strategic deals while building systems that scale beyond you.
- Design and evolve GTM strategy. ICPs, pricing, outreach, sales cycles, and channels.
- Build the machine. Playbooks, KPIs, forecasting, CRM hygiene, and clear accountability.
- Partner with leadership. Be a sparring partner to the CEO on commercial strategy and growth decisions.
- Stay close to the market. Turn customer insights into better positioning and stronger conversion.
- Develop yourself. This role should evolve to a CRO overtime.
✨ This Role Is Right for You If…
- You’ve already scaled a B2B sales org from early revenue to ~€10M+ ARR (or similar order of magnitude).
- You know what breaks when a company moves from “early wins” to “repeatable growth”.
- You’re comfortable leading a team while still rolling up your sleeves.
- You have a great sales method to navigate complex multi stakeholder enterprise deals.
- You bring structure without slowing things down.
- You thrive in fast-moving environments with ambiguity and high ownership.
- You think in quarters and not hitting your goals is an embarrassing disaster for you. 😉
- You’re motivated by building something meaningful — and making a real climate impact.
🤩 Why This Should Excite You
- You’ll sell cutting-edge HW/SW + AI climate tech into some of the most respected industrial, enterprise, and energy players in Europe
- Your customers will include EU & DE energy infrastructure operators, from SMB to large enterprises, and Fortune-level companies
- You’ll help scale a product that is already in market, revenue-generating, and mission-critical for customers with real-world infrastructure
- You’ll shape the go-to-market motion from Series-A-ish scale to €10M+ ARR, with full ownership and direct CEO access
💪 Skills & Experience
- Scaled B2B SaaS revenue from early traction to ~€10M+
- Hands-on seller turned sales leader with rolling up your sleeves attitude
- Track record of hitting goals in hyper growth environment
- Fluent in English & German; CRM savvy (HubSpot a plus)
