About Matthias Isler
Entrepreneur / CTO at Effinuity
--- Please read before booking: Due to limited capacity, I currently offer mentoring sessions exclusively to founders and executives of startups or scale-ups. I’m not able to provide career advice or general coaching. Thanks for your understanding.
I’ve spent 20 years in software engineering, including a decade as a CTO, building, scaling, and leading engineering teams and technology ventures. I’ve founded multiple startups, grown SaaS and marketplace businesses to seven-figure revenues, and achieved a successful exit.
I specialize in technology strategy, AI integration, and scaling engineering teams, helping startups navigate technical challenges, product development, and growth bottlenecks. I’ve worked across SaaS, AI, cloud infrastructure, and digital transformation, ensuring founders make smarter technical decisions that align with their business goals.
Whether it’s validating an idea, optimizing a product roadmap, hiring the right engineers, or avoiding expensive technical mistakes, I bring hands-on experience to help turn ideas into scalable businesses. I don’t just offer theory or abstract strategies—I provide practical, real-world insights from years of building, growing, and leading technology companies.
