Job Description

Startup Wise Guys (SWG) is one of Europe’s most active B2B accelerators, with a strong track record of helping founders turn early ideas into real companies. Through Founders Club, we bring together senior builders to form teams, validate market problems, and ship the first version of a scalable product in a structured, execution-focused environment.

If you’ve spent years building other people’s SaaS, this is your chance to build your own—with the right peers, support, and momentum.

This is a co-founder opportunity. The goal is to help you become (or join) a founding team and launch a venture.

Tasks

  • Co-create & validate a B2B SaaS idea with other founders (or bring your own)
  • Run customer discovery and translate insights into product requirements
  • Define MVP scope and ship fast (architecture, stack, rapid iterations)
  • Set up engineering foundations (repo, CI/CD, security basics, monitoring)
  • Collaborate on early GTM experiments (activation, onboarding, pricing tests)

Requirements

  • 7+ years in software engineering / product engineering (hands-on welcome)
  • Strong full-stack mindset (APIs, data, frontend, shipping cadence)
  • Comfort making pragmatic MVP tradeoffs (speed > perfection)
  • You want to be a technical co-founder, not “the dev for hire”
  • ~10–12h/week for 12 weeks (sessions + execution)

Benefits

  • Build your own product in 12 weeks (validation → MVP → iteration)
  • Weekly execution & accountability ( ~10–12h/week, clear deliverables)
  • Access to 500+ B2B mentors (product, tech, sales, fundraising)
  • 440+ alumni startups in 40+ countries (network, intros, benchmarks)
  • Founder-grade CTO toolkit (MVP scoping, stack choices, investor tech story)

Note To ensure high commitment and quality, the program includes a participation ticket after acceptance.

Apply if you’re ready to stop being the “CTO for others” and start building a company around your own product.
