Sales-oriented co-founder

Salary Competitive
Equity To be negotiated

We parse accounting and procurement data and translate it into actual kilograms of materials purchased and from there into supplier- and material-level CO₂e with a transparent audit trail.

We are currently in dialogue with several VCs and angel investors moving toward the first seed round. Before closing funding, we must demonstrate strong market validation and commercial traction. You will be a part of the market validation process.

Our initial beachhead market is ESG consultants in Denmark.

You will:

  • Define and execute our go-to-market strategy

  • Validate positioning and messaging with ESG consultants

  • Build early pipeline and close first paying customers

  • Shape pricing, packaging, and value proposition

  • Help build the commercial narrative for investors

  • Recruit and lead the future commercial team


You will work directly with the founder and shape the company at its earliest stage.


Who You Are

You likely have experience in one or more of the following:

  • B2B SaaS sales (ideally early-stage)

  • ESG / sustainability consulting

  • Enterprise or mid-market solution selling

  • Building outbound motions from scratch

  • Positioning technical products for non-technical buyers


But more importantly:

  • You want to build something meaningful

  • You care about climate impact beyond marketing language

  • You are motivated by ownership and long-term value creation

Working at
TrueMass

Today, companies report sustainability metrics using estimates, averages, and spreadsheets. That creates noise, greenwashing risk, and enormous manual work. ESG reporting is becoming mandatory under regulations like CSRD, but the underlying data foundation is broken. We fix that. Our platform parses real accounting and procurement data and converts it into structured, auditable, product-level environmental insights. Instead of guessing emissions from spend categories, we calculate impact based on actual quantities, materials, and suppliers. We turn financial transactions into physical truth.
