You bring the idea. We figure out what it needs to become, then build it properly.
Most product failures happen before the first line of code is written. Building a great digital product requires more than typing syntax — it requires strategic clarity, thoughtful architecture, human-centered UI/UX, resilient database design, and end-to-end engineering discipline. Whether you are launching a venture, modernizing a business platform, or turning a complex idea into software, I take the product from architecture through production deployment.
WHO THIS IS FOR:
- Founders and leadership teams with a serious product idea that needs to become a real, high-performance product.
- Companies building new digital products, SaaS platforms, internal operating systems, or transactional platforms.
Bring me the idea, the architecture, the technical decision or the problem you're stuck on. We leave with clarity.
Software mistakes compound fast. Choosing the wrong database model, picking an overly complex framework, or misunderstanding data relationships can cost a company hundreds of thousands of dollars and months of lost momentum. In a single 90-minute intensive session, we dissect your architectural challenge, identify hidden bottlenecks, evaluate trade-offs, and map out the exact technical path forward.
WHO THIS IS FOR:
- Founders preparing to write code or hire a dev team and needing an unbiased architectural review.
- Engineering leaders facing performance bottlenecks, scaling issues, or architectural dead-ends.
Sometimes you don't need another employee. You need someone who can see the problem from a different altitude.
Founders carry immense psychological and operational weight. You are constantly making decisions with incomplete information — deciding what to build, what to kill, how to price, who to hire, and how to allocate scarce engineering and capital resources. My Founder Advisory practice provides seasoned, candid guidance at the intersection of business strategy, product intuition, and technical reality.
WHO THIS IS FOR:
- Early-stage and growth-stage tech founders navigating high-stakes product or business forks.
- Solo founders who need a rigorous strategic sounding board and execution partner.
For companies that need experienced technical leadership to establish engineering standards, guide architecture, and scale systems.
Hiring a seasoned full-time CTO before your company is ready can cost $300k+ in compensation and equity, while operating without experienced technical leadership leads to catastrophic technical debt, bad hires, and unscalable software. As a Fractional CTO, I step into your executive team to provide senior architectural stewardship, institute rigorous engineering workflows, and build an engineering culture of excellence.
WHO THIS IS FOR:
- Funded startups and growth companies preparing for scale or institutional investment.
- Non-technical founding teams needing authoritative engineering leadership.
Bring Harry into the room.
Harry Zahavi delivers uncompromising, intellectually dense, and electrifying keynotes that bridge the worlds of deep software engineering, venture creation, and human self-mastery.
