Job Description

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.

 start in stealth mode with anonymity, protect conversations with built-in NDAs, and reveal more when you are ready, at your pace, with the right partner.

→ Relevant matches based on your startup reality:
 Meet candidates filtered by budget, availability, equity/cash preferences, and commitment level. Whether you're part-time and bootstrapped or full-time and fundraised.

What Makes a Great Match

We're excited to connect with founders who bring:


• Bold Vision: You have a compelling FinTech startup idea and the natural ability to motivate others to join you on the journey toward ambitious goals.


• Entrepreneurial Spirit: You're energized by challenges, love finding creative solutions, and are excited about building something meaningful from scratch.


• Strong Communication: You enjoy working with others and can effectively share your ideas while building productive relationships with technical team members.
