Does This Sound Familiar?
"We're about to raise Series A but investors are concerned about our tech stack"
Your team built fast, but now technical debt is a fundraising blocker. You need credibility and a clear modernization plan.
In 2 weeks: Investor-ready technical report + 6-month roadmap. One client used this to close their $4M round.
"We promised a feature to our biggest client in 6 weeks. Our team is maxed out."
Revenue depends on shipping, but hiring takes months and you can't afford delays or poor quality.
Senior developer embedded in your team, shipping production code in weeks, not months. No recruitment overhead.
"Our junior engineers are talented but need guidance. We can't afford a senior hire yet."
Team velocity is slow because juniors lack patterns and best practices. Code reviews are a bottleneck.
6-month mentoring program. Past clients saw 2x faster onboarding and 40% reduction in bugs.

What Clients Say
"Yonatan helped us pass technical due diligence for our Series A. His audit identified 3 critical issues we fixed before investor meetings. We closed $5M two months later."
"We were drowning in technical debt. Yonatan embedded with our team for 8 weeks, refactored our core API, and taught our engineers modern patterns. Our deployment time went from 2 hours to 15 minutes."
"As a non-technical founder, I needed someone to translate tech decisions into business impact. Yonatan's fractional CTO work gave me confidence to make smart hiring and architecture choices."
"Our junior engineers were struggling with system design. After Yonatan's 3-month mentoring program, they're shipping features independently. We saved $150K in senior hires."

Frequently Asked Questions
How quickly can we start?
Most engagements kick off within 1 week of agreement. For urgent needs, I can start within 2-3 business days.
Do you work on-site or remote?
Primarily remote with flexibility for occasional on-site sessions (based in Israel, available for EU/US time zones). I've successfully worked with distributed teams across continents.
What if we need a different tech stack?
I'm technology-agnostic and pick up new stacks quickly. If it's significantly outside my core expertise, I'll be upfront and can recommend specialists.
Can you help with hiring?
Yes—part of fractional CTO work includes creating job descriptions, screening candidates, and technical interviews. I can also help build your hiring process.
Do you sign NDAs?
Absolutely. Confidentiality is standard for all engagements. I can also work within your existing security and compliance requirements.
What's your availability?
I typically work with 3-5 clients at a time to ensure quality. Current availability varies—reach out for a commitment timeline.
Do you offer equity-based arrangements?
For the right early-stage startup with strong alignment, I'm open to hybrid cash + equity structures. Let's discuss during the discovery call.
