Job description

ABOUT THE ROLE

We are a venture studio. We research and validate ideas in-house, then bring in an Entrepreneur inResidence to turn the strongest of them into real companies. Each venture starts with a clear thesis, a budget and a small team already in place.

As EIR, you lead one venture from early build to a standalone business. You work with a small cross-functional team across product, growth, sales and engineering, test quickly with realcustomers, form the company, and hand it to a long-term CEO once it is ready to raise.

You are the single accountable owner from start to handover. This is a hands-on operating role, not an advisory one. You push forward when the evidence supports the venture and recommend stopping early when it doesn't.

• Lead the product build with a small cross-functional team
• Use AI and no-code tools to ship product, research and assets quickly

External Relationships

• Lead conversations with partners, early customers, suppliers and service providers
• Drive early business development and first commercial deals
• Manage contractors and specialists who don't report to you directly
• Keep leadership and investors informed with regular, concise updates

Company Formation

• Set up the legal entity, payments and core operating systems
• Put basic finance, legal and reporting processes in place
• Recruit the venture's first hires
• Document decisions, systems and metrics so the business can run without you

Transition

• Help recruit the venture's long-term CEO
• Hand over the business cleanly and on schedule
• Flag risks early to studio leadership before they cost time or money
• Share lessons learned to improve how the studio builds future ventures

SUCCESS METRICS

• MVP live with paying or active users within the first 90 days.
• Clear traction evidence that supports further investment, or an early, well-reasoned stop recommendation
• Consistent weekly delivery across all work streams
• Entity, payments and first hires in place on schedule
• Long-term CEO hired and handover completed within the agreed timeline MUST-HAVE EXPERIENCE
• Built or led a venture from zero as a founder, early operator or EIR

Leadership & Communication

Leads without formal authority

Clear, proactive written communication

• 6+ years of experience in startup operations, venture building, general management, or a comparable operating role, ideally spanning more than one company.

• Direct, hands-on experience taking at least one company from zero to launch, not just supporting someone else's launch, but owning it.
• Strong working knowledge of AI tools and agentic workflows, with a track record of using them to replace team-based work, not just accelerate individual productivity.
• Experience designing or operating a structured process for de-risking new initiatives—stage gates, funnel management, or comparable venture-building systems.
• Hands-on experience managing execution across multiple work streams, products, or business lines simultaneously without relying on a large team.
• Excellent communication skills, with the ability to provide concise, honest assessments of portfolio or business health.
