đź“‹ Description
- • Sisu is not just an incubator; it's a launchpad for the next generation of groundbreaking companies, and we're seeking visionary technologists to step into the pivotal role of CTO Co-founder. This is a unique, founder-friendly program designed to partner with exceptional entrepreneurs from the very genesis of an idea – often referred to as 'day minus one.' Our mission is to empower you, the technical visionary, to bring your most ambitious startup concepts to life, providing unparalleled guidance, resources, and a collaborative ecosystem to navigate the critical first twelve to eighteen months of your venture's journey.
- • As a CTO Co-founder within the Sisu program, you will be at the forefront of innovation, taking ownership of the technical strategy, architecture, and development of a new, disruptive startup. This is a hands-on role where your deep technical expertise will be the bedrock upon which a successful company is built. You will be instrumental in shaping the product from its nascent stages, translating bold ideas into tangible, scalable solutions. This isn't about managing a team from afar; it's about rolling up your sleeves, architecting robust systems, making critical technology decisions, and leading the technical execution with relentless drive.
- • Our founder, Ari Mir, brings over two decades of experience building and scaling successful ventures, including two companies that have achieved over $100 million in annual revenue and employed more than 1,000 individuals. This means you will benefit from direct mentorship from a proven entrepreneur who understands the challenges and triumphs of building impactful companies from the ground up. Ari's insights, strategic guidance, and network will be invaluable as you navigate the complexities of product development, team building, and market entry.
- • The Sisu program is highly selective, admitting only 20 founders per year across 10 distinct startups. This exclusivity ensures a focused, high-impact experience for every participant. You will collaborate with a cohort of equally ambitious and talented founders, fostering a community of shared learning, mutual support, and constructive challenge. This peer network is a critical component of the Sisu experience, providing diverse perspectives and a sounding board for your ideas.
- • Your responsibilities will encompass the full spectrum of technical leadership in a startup environment. This includes defining the technical vision and roadmap, selecting appropriate technology stacks, designing scalable and resilient architectures, overseeing the development lifecycle from MVP to beyond, and ensuring the technical feasibility and quality of the product. You will be expected to identify and mitigate technical risks, make data-driven decisions, and stay abreast of emerging technologies that could provide a competitive edge.
- • Beyond the core technical execution, you will play a crucial role in shaping the company's overall strategy. This involves working closely with your co-founder(s) to define the product-market fit, develop go-to-market strategies, and contribute to fundraising efforts. Your ability to articulate complex technical concepts to non-technical stakeholders, including investors, will be paramount. You will be a key voice in representing the technological potential and execution capabilities of the startup.
- • We are looking for individuals who possess not only profound technical acumen but also an innate entrepreneurial spirit. You should be someone who thrives in ambiguity, embraces challenges, and possesses the resilience to overcome inevitable obstacles. The ideal candidate is a proactive problem-solver, a strategic thinker, and a natural leader who can inspire and guide technical teams as the company grows.
- • This opportunity is designed for those who are ready to commit fully to building something extraordinary. It requires a deep well of ambition, a willingness to learn and adapt, and an unwavering belief in the power of innovation. If you are a top-tier engineer, a machine learning expert, a cutting-edge product builder, or possess expertise in any other deeply technical field, and you are driven by the desire to create a lasting impact, Sisu offers the platform and support to turn your entrepreneurial aspirations into reality. This is your chance to be the technical architect of your own success story, backed by a founder-led incubator with a proven track record.
🎯 Requirements
- • Deep technical expertise in software architecture, systems design, product development, or a related cutting-edge technical field (e.g., Machine Learning, AI, advanced data science).
- • Proven track record of building and shipping complex software products or systems, demonstrating strong engineering fundamentals and problem-solving skills.
- • Demonstrable entrepreneurial drive, ambition, and a proactive mindset towards identifying opportunities and overcoming challenges.
- • Strong collaborative and communication skills, with the ability to work effectively with co-founders, advisors, and potential technical teams.
🏖️ Benefits
- • Direct mentorship and guidance from Ari Mir, a serial entrepreneur with a proven track record of building multi-million dollar companies.
- • Opportunity to be a technical co-founder of your own startup, with significant equity potential.
- • Access to Sisu's network of advisors, investors, and industry experts.
- • A structured 12-18 month program designed to accelerate startup growth, including support with co-founder matching, MVP development, and fundraising.
