Customer Acquisition Manager

About CLER

At CLER, we’re redefining clean air. We are a Swedish deep-tech start-up on a mission to set a new global standard for air purification. Our proprietary, filter-free technology delivers ultra-clean air with no maintenance, lower energy consumption, and a far more sustainable footprint than traditional solutions.

Why this matters:

• 99% of the world’s population breathes air that fails to meet WHO guidelines, causing more than seven million deaths each year.


• Indoor air quality is often 2–5x worse than outdoor air, even though we spend 90% of our lives indoors.

CLER is built on smart Swedish engineering and rigorous innovation. Our ambition is bold: to redefine how the world cleans its air—by cutting waste, reducing CO₂ emissions, and protecting public health at scale.

We are early in our growth journey, which means this is your chance to join at a stage where impact, responsibility, and opportunity are at their highest.

About the Role

We’re looking for a driven, hands-on Account Executive / New Business / Customer Acquisition Manager to build CLER’s customer base from the ground up. This is a highly important growth role focused on acquiring new customers, opening doors, and closing real business. Are you ready to take the next step and grow within sales? Then this is for you.

The successful candidate will grow their deals and processes into real Key Accounts that we will scale internationally. You will be surprised by the calibre of companies that have already signed with CLER—and the reasons behind it. This is your chance to join something truly special at an early stage of the company’s journey.

You will own the full sales process—from identifying and contacting decision-makers to running meetings, site visits, negotiations, and closing deals. You’ll help shape how we sell, what works, and how we scale. This is a role for someone who wants to build, move fast, and see direct results from their efforts. If you thrive in responsibility, pace, and ownership, this is where you will accelerate faster than in any established organisation.

What you will be doing

• Own the full end-to-end sales cycle: prospecting, meetings, site visits, qualification, negotiation, and closing.


• Actively build your own pipeline through LinkedIn, phone, e-mail, and field activity.


• Manage and close leads from our team at Marketing Acquisition.


• Meet and sell directly to decision-makers within QSR (Quick Service Restaurants) and commercial businesses.


• Work closely with leadership and product to feed back market insights and customer needs.


• Help shape our sales playbook, processes, and tools as we scale.


• Move with pace: prospect, demo, follow up, negotiate, and close – with grit and momentum.

Whom are we looking for

• A strong drive to work with new customers and new business.


• Comfortable taking full responsibility for your numbers, pipeline, and results.


• Thrives with ownership and freedom rather than heavy structures.


• Moves fast, takes initiative, and doesn’t wait to be told what to do.


• Naturally curious and eager to learn from the market, customers, and outcomes.


• Open to feedback and committed to continuous improvement.


• Willing to put in extra effort when needed—not because it’s demanded, but because you care about winning.


• Motivated by performance, progression, and building something from an early stage.

Formal years of experience matter less than mindset. The right ambition and energy will outperform a perfect CV.

Extra +

• Field sales experience


• Background from QSR, such as McDonald’s or similar


• Experience from high-tempo sales environments such as security, IT/telco, or real estate


• Interest in tech, sustainability, and scalable solutions

What We Offer

• A true early-stage role in a high-ambition start-up where performance is noticed quickly.


• The opportunity to grow fast into larger deals, key accounts, and more responsibility as you prove yourself.


• A small, driven team with a flat hierarchy and direct access to decision-makers.


• Competitive salary and commission structure with strong upside.


• Centrally located office in Stockholm.


• Most importantly: real impact—contributing to reduced waste, lower CO₂ emissions, and better public health.
