About the venture

I’m working on a new SaaS platform in the investment/finance space. The market is large, underserved, and ripe for disruption. The product is already scoped at MVP stage with clear validation from potential users, and there’s a strong route to funding once we launch.

This is an equity-only co-founder role until funding is secured. The expectation is a meaningful equity stake (10–25% depending on fit) and the opportunity to step into a CTO-level position as the company grows.

The role

You’ll take full ownership of the product build: from MVP to scalable SaaS platform. Expect to:

• Build core dashboards and update automation tools
• Develop APIs and integrations for founder–investor workflows
• Shape product architecture and technical roadmap
• Be a true co-founder: involved in strategy, vision, and execution

What I’m looking for

• Full-stack engineer (React/Next.js + Node.js/Python preferred)
• Strong experience building and shipping MVPs or SaaS products
• Startup mindset: pragmatic, fast, and resourceful
• Are execution focused - we are at the point where we need to build
• Interest in fintech / venture capital tools a plus
• UK Based applicants only

What’s on offer

• Equity co-founder role (10–25%, depending on fit and contribution), No salary until funding — ideal for someone with financial runway or moonlighting flexibility
• The chance to build a product from zero, with ownership over technology
• A role that can scale with you
• Market with strong tailwinds and clear monetisation strategy, with several clients already lined up

At Zelt, we’re not just building HR software - we’re reinventing how modern companies run HR, payroll, IT, and finance. We’re at a pivotal moment in our journey: growing rapidly, backed by top investors, and expanding our footprint in the United Kingdom and beyond.

As Founder Associate, you’ll sit at the heart of this growth. You’ll work directly with the CEO, partner with the leadership team and investors, and take full ownership across sales enablement, marketing, finance, culture, special projects and operations.

This role is a launchpad. Many of today’s startup founders, VPs, and investors began their careers in Founder Associate roles. If you are coming from consulting, or another high-performance environment, this is your chance to move from advising to building at exactly the right time.

What you’ll be working on:

• Sales Operations & Enablement: Support commercial teams with pipeline tracking, CRM processes, performance analysis, and enablement materials.
• Marketing & Growth: Plan and execute events, conferences, awards submissions, and campaigns. Experiment with growth-hacking initiatives to amplify brand visibility.
• Culture & People: Contribute to building and nurturing Zelt’s culture, ensuring we remain a high-performing and inspiring place to work.
• Special Projects: Lead cross-functional initiatives directly from the CEO’s office
• Investor & Board Reporting: Prepare and deliver high-impact reports and presentations for our investors and board.
• Finance: Oversee bookkeeping and finance ops, VAT filings, and monthly closes. Work closely with and supervise our external finance partner on accounting and controlling.
• Company Operations: Run the day-to-day business engine, ensuring Zelt operates smoothly across all functions.

What we’re looking for:

• 1–3 years of experience in a top-tier management consulting, VC/PE, or a high-growth startup.
• Exceptional analytical and problem-solving skills, with strong financial acumen.
• Excellent communication skills; able to present confidently and collaborate across teams.
• Entrepreneurial mindset and ownership mentality - you thrive in fast-moving environments.
• Interest in technology, SaaS, and scaling businesses.

Why join Zelt?

• Join at a pivotal time as Zelt scales rapidly in the United Kingdom and internationally.
• Work side-by-side with the CEO on the company’s most critical decisions.
• Exposure to top-tier investors and board members.
• True breadth: finance, sales, marketing, culture, and strategy - no two weeks will be the same.
• A fast track into leadership, entrepreneurship, or VC.
• Competitive compensation and the opportunity to shape the trajectory of a high-growth SaaS company.
