About ThirtyEight Capital

ThirtyEight Capital is a venture-building and investment platform focused on building scalable, profitable businesses in large, fragmented industries.

Rather than investing passively, we partner with exceptional operators and entrepreneurs from the very beginning: helping them validate ideas, shape business models and build companies from zero to one.

Our focus is not on building “growth-at-all-costs” startups.

We believe the best businesses are built with strong fundamentals from day one:

• clear customer value
• operational excellence
• efficient distribution
• and an early path to profitability

We particularly focus on sectors where execution matters more than hype:

• Energy & climate
• Local services
• Healthcare & consumer services
• Real estate
• Vertical software & operations

Most of the industries we target are highly fragmented, operationally inefficient and underserved from a customer experience perspective - creating opportunities to build strong, durable businesses with long-term value creation.

We are not looking for employees. We are looking for future founders who want to build real companies with real ownership.

Tasks

We are looking for entrepreneurial individuals interested in building companies in the energy and climate space together with ThirtyEight Capital.

This is not a traditional operating role with predefined responsibilities.

nstead, the goal is to jointly identify, validate and potentially build scalable and profitable businesses from scratch.

Potential areas of focus include:

• Heating & heat pump ecosystems
• Energy financing models
• SME-focused climate solutions
• Installation & service infrastructure
• Energy optimization
• “Energy as a Service” models
• Building technology & modernization

You might already:

• have identified inefficiencies in the market
• be exploring your own ideas or theses
• have industry experience
• or want to start a company but are looking for the right partner and setup

Together, we would:

• explore market opportunities
• validate business models
• develop operational concepts
• build first commercial traction
• and potentially launch a venture together

Our approach focuses on building real businesses with strong fundamentals:

• operational excellence
• efficient customer acquisition
• clear unit economics
• and an early path to profitability

Rather than “growth at all costs”, we believe in building durable companies with long-term value creation.

Requirements

We are less focused on traditional CVs and more interested in entrepreneurial potential, ownership mentality and strong execution capabilities.

Ideal backgrounds could include:

• Energy / HVAC / heating industry experience
• Experience in installation, operations or field services
• Commercial or sales-heavy backgrounds
• Entrepreneurial or startup experience
• Strong operational mindset
• Technical understanding of energy-related systems

You do not need to have founded a company before.

What matters most:

• curiosity and initiative
• ability to operate in ambiguous environments
• willingness to build from zero
• strong work ethic
• commercial instinct
• desire to create a meaningful business long-term

We are especially interested in people who already bring:

their own ideas / market insights/ customer pain points or strong opinions on where the industry is heading

- Direct collaboration with experienced founders and operators

- Access to capital from day one

- Strategic and operational support during the build phase

- Access to an entrepreneurial network across venture, finance and operations

- Joint ideation and company building

- Extremely entrepreneurial environment with high ownership
