Job Ad Founding Account Executive

We Are Hiring!

01.05.2026

Founding Account Executive (B2B SaaS) 

Join Sealytix and help shape the commercial future of a company already trusted by some of the world’s largest container carriers. 

Where Sealytix is Today 

Sealytix develops groundbreaking, unique AI stowage and capacity optimization software for container shipping. Our CAPSIM™ engine and optimization suite boost executable capacity, cut bunker use, and increase yield while making vessels safer and greener. By delivering precise, sellable capacity forecasts and operational plans that convert forecasted slots into executable cargo, our technology disrupts how carriers manage revenue and operate vessels.

Founded in 2019 and based in Copenhagen, Sealytix is privately owned, economically sustainable, and already delivering multiple SaaS deployments. Today we work with more than 25% of the world’s largest container carriers.

We are in the midst of a commercial breakthrough and aiming to capture over 80% of the market. To achieve that within the next two years, we must scale our commercial organization rapidly. This Founding Account Executive role is a critical hire in that push: you will join a company with real customers, real revenue, and a clear mandate to scale fast.

What Sealytix Does 

Our AIdriven stowage and capacity optimization products deliver measurable impact for global carriers: 

  • 5–10% higher executable capacity 
  • 10–15% higher yield 
  • €1M+ annual bunker savings per vessel 
  • 50–70% faster stowage planning 
  • Reduced CO₂ emissions and improved CII compliance 
  • Lower risk of container loss and onboard fires 

We help carriers move more cargo, more safely, with less fuel — by enabling smarter stowage, capacity, and booking decisions. Our tools also streamline collaboration between carriers and terminals, saving critical time. 

Your Role 

As our Founding Account Executive, you will not be starting from zero — you will inherit a functioning sales process and an active pipeline built by the management team. Your mission is to take ownership, professionalize, and scale this engine. 

You will: 

  • Own and advance our pipeline by continuing existing customer dialogs while building new opportunities. 
  • Take over CRM ownership and refine our sales process, reporting, and forecasting. 
  • Run highcredibility conversations with operations, stowage, network, and commercial leaders at top global carriers. 
  • Translate deep operational value into commercial outcomes for highly technical buyers. 
  • Shape pricing, packaging, and deal strategy directly with the CEO. 
  • Bring customer insights into product development and ICP refinement. 
  • Represent Sealytix externally - at conferences, customer workshops, and industry forums. 

This is a builder role, but not a blank slate — you join a company with real customers, real revenue, and a proven sales motion. 

Who You Are 

You are a consultative, analytical seller who thrives in complex operational environments and can build trust with technical stakeholders. You understand that early sales in maritime and operational SaaS require credibility, patience, and domain curiosity. 

You likely bring: 

  • Experience selling B2B SaaS (€50k–€200k ARR or higher). 
  • Background in maritime, logistics, industrial, or optimization software — or the ability to master complex operational domains quickly. 
  • High commercial drive with a proven track record.
  • Experience generating a pipeline beyond inbound channels. 
  • Strong ability to unpack operational workflows and quantify value. 
  • A founderlike mindset: resourceful, persistent, and comfortable with high ownership. 
  • Experience as a first sales hire or early GTM builder (nice to have). 
  • Excellent written and spoken English. 
  • Willingness to travel internationally frequently. 

What We Offer 

  • A true founding role with direct influence on GTM, product, and strategy. 
  • Competitive compensation with meaningful commission upside. 
  • A seat at the table — work directly with the CEO and leadership team. 
  • A modern, R&Ddriven culture with fast decisions and minimal bureaucracy. 
  • Highimpact work with global visibility. 
  • Flexibility: Copenhagen preferred, but remote within Europe is possible. 
  • A careerdefining opportunity to shape the commercial engine of a company solving one of maritime’s hardest problems.

André Team Introduction Linkedin Post 2

Announcement

03.03.2026

We are proud and happy to announce that Andre Martin Nielsen has joined Sealytix as our new Chief Product Officer.

André will work with Claus Vesterdal and our development teams to ensure that our customers get products with maximum business value and ease of use. He will also manage key accounts and oversee onboarding and customization activities.

André is an internationally leading expert in stowage software products. His career journey has provided him with comprehensive insights into the industry's lifecycle — from the fundamental execution of Bills of Lading to the complex stowage coordination of 19,000 TEU container vessels.

He started at COSCO SHIPPING (formerly China Shipping) in 2007 as a Ship Manager and Stowage Coordinator. He successfully executed the Hamburg port debut of the world’s largest and longest (400m) container vessel. He also led capacity expansions and drove operational efficiency through various IT initiatives, gaining deep strategic insights into head-office operations.

Our team at Sealytix then had the pleasure of working with him from 2014 to 2019, where he was hired at Navis. Here, he transitioned into software development and product management, focusing on stowage optimization solutions. In close collaboration with our optimization team, he delivered tools that empowered users to maximize vessel intake and improve overall stowage visibility.

In 2019, André moved to HPC Hamburg Port Consulting GmbH to bridge the gap between carrier operations and terminal logistics. During his seven-year tenure, he gained extensive experience with both "greenfield" and "brownfield" terminal projects. Since 2024, Sealytix again enjoyed working with him as an excellent facilitator of the development of a special version of our SLX | STOW product for HVCC Hamburg Vessel Coordination Center GmbH.

We warmly welcome André to Sealytix. We are busy moving forward and André fits right in.

R.M. Kaleris APAC

Announcement 

21.09.2025

We are happy to announce that Sealytix will be a sponsor of Kaleris' APAC Regional Maritime Summit in Singapore next week, 22-24 September 2025.

Together with Bastian Gehnke and Michael Haddon Holst, our CEO will give a talk at 1:15 pm on day 2 about the CAPSIM Plugin for STOWMAN, a stowage optimization and compliance tool that we developed in collaboration with Kaleris.

It solves lashing, stress force, and IMDG errors in a stowage plan, enabling planners to reduce planning time by 50-70%.

In addition, it can reach target trim and VCG with cargo rather than ballast water, driving more cargo loaded and significant bunker savings - $250K - 500K annually.

Big thanks to Martin Bardi and Selke Eichler for making this happen.

Jaike Van Twiller Postdoc

Postdoc on guiding stowage algorithms with deep ai

21.08.2025

We are excited that Jaike van Twiller will start a PostDoc at the IT-Universitetet i København in September with support from Den Danske Maritime Fond.

Jaike will continue his exploration of using deep learning for container vessel stowage planning.

In his PhD thesis, he showed that reinforcement learning is superior to deal with cargo and yield uncertainty.

In his PostDoc, he will continue Agnieszka Sivertsen's excellent work on applying AI to guide the search process of modern stowage algorithms based on large neighborhood search.

It’s an approach with great potential for speeding up these algorithms dramatically. This is invaluable for their applications in the liner shipping industry.

A.S. Successful Phd Defense

Successful PHD Defense

24.06.2025

Big congratulations to Agnieszka Sivertsen for successfully defending her industrial PhD with Sealytix at Roskilde University

Not surprisingly, Aga has studied the containership stowage planning problem. This problem sits at the heart of utilizing the capacity of containerships. Bad planning can easily lead to a loss of more than 15% of executable capacity, hurting the bottom line of carriers and causing unnecessary CO2 emissions. It is hard to believe that this is an area with fewer than 200 scientific publications since container shipping was introduced more than 60 years ago.

Aga has gone to great lengths to change this state of affairs. One big challenge for the research community is the lack of data. To that end, Aga has published the largest benchmark suite to date based on real cargo and vessel data. Another hurdle is the complexity of the problem. Scientists cannot use decades of their career just to understand the major combinatorial aspects of an optimization problem. To address this, Aga, together with experts from Sealytix, has formulated a so-called representative container stowage planning problem (RCSPP). This formulation avoids unnecessary details and defines the main aspects in the simplest way possible. The RCSPP is representative in the sense that an algorithm solving it well can also be assumed to be efficient on the real problem.

These are great contributions to the research community, but Aga went beyond and published a new large neighborhood search algorithm to solve the RCSPP, including some innovative ideas on applying machine learning to guide the search. The latter has evolved into a research project in itself and is now pursued at IT-Universitetet i København by Jaike van Twiller with support from the Den Danske Maritime Fond.

Thank you, Line Reinhardt, for supervising Aga, and thank you, Innovation Fund Denmark, for supporting this PhD project financially.
