Designer Interview
40 questions
I design to build. Early on, I realized the world doesn't need more designers — it needs builders who understand that form, function, and business strategy are inseparable.
Could you please tell us more about your art and design background? What made you become an artist/designer? Have you always wanted to be a designer?
I design to build. Early on, I realized the world doesn't need more designers — it needs builders who understand that form, function, and business strategy are inseparable. I became a designer because it's the fastest way to move an idea into reality and scale it into a category-defining product.
Can you tell us more about your company / design studio?
TMD is a design and innovation lab focused on advanced mobility, aerospace, and autonomous systems. We operate as a venture builder: we identify market gaps at the intersection of technology and human need, design breakthrough solutions, and partner with companies to bring them to market. Not freelance. We own outcomes.
What is "design" for you?
Design is applied strategy. It's the discipline of turning complexity into clarity, and vision into execution. Every design decision should answer: Does this drive adoption? Does this create defensible advantage? Does this compound value? If the answer isn't yes, it's not design — it's decoration.
What kinds of works do you like designing most?
Category-defining products in transportation, aerospace, and robotics. Systems where design directly impacts safety, performance, cost, and human experience simultaneously. Work that ships at scale, not prototypes that live in museums.
What is your most favorite design, could you please tell more about it?
The AIR ONE eVTOL I designed. Not because it's beautiful, but because it's the first aircraft in its class flying under FAA certification with 2,900+ pre-orders and a commercial launch timeline. That's not design - that's proof of concept that translates to real revenue and market leadership.
What was the first thing you designed for a company?
Advanced autonomous platforms for strategic defense applications. Learned immediately that the gap between "good design" and "winning design" is whether it actually solves the customer's most expensive problem.
What is your favorite material / platform / technology?
Carbon fiber composites and advanced alloys when weight matters. But honestly? Data. Real user feedback. Constraint. The best designs emerge from severe constraints - thermal limits, weight budgets, regulatory frameworks. Unlimited budgets produce mediocrity.
When do you feel the most creative?
When I understand the entire system: the market, the customer's real problem, the technical limitations, the regulatory pathway, the business model. Creativity without systems thinking is noise. Creativity within constraints is leverage.
Which aspects of a design do you focus more during designing?
Form follows function. Function follows strategy. So: (1) Does this solve the real problem? (2) Can we manufacture/deploy at scale? (3) Does this create defensible IP? (4) What's the path to revenue? Design that doesn't answer these isn't design.
What kind of emotions do you feel when you design?
Urgency. I'm building against time and competition. The satisfaction isn't in the beauty - it's in the moment a customer says "this works better than anything else on the market."
What kind of emotions do you feel when your designs are realized?
Validation that the vision translates. But that's just the start. The real emotion comes when the product ships, generates revenue, and creates a category. That's when design becomes power.
What makes a design successful?
Three things, in order: (1) Market adoption at scale. (2) Defensible competitive advantage. (3) Revenue and profitability. If people aren't buying it, if competitors can copy it easily, or if the unit economics don't work, the design failed.
When judging a design as good or bad, which aspects do you consider first?
Does it solve a real, expensive problem? Is it manufacturable? Is it better than alternatives? Will customers pay premium price for it? If you can't answer yes to all four, it's not good design.
From your point of view, what are the responsibilities of a designer for society and environment?
Build systems that actually improve life, not marketing narratives about improvement. Design for sustainability means designing for profitability (sustainable business). Design for accessibility means designing for simplicity (which also reduces cost). Good design for society and good design for business are the same thing.
How do you think the "design field" is evolving? What is the future of design?
Designers are finally becoming builders. The best designers I know are founders, not creatives. Design is merging with engineering, business strategy, and systems thinking. The future belongs to people who can simultaneously optimize for aesthetics, physics, manufacturing, cost, regulation, and market demand. Specialists in "design" alone are becoming commoditized.
When was your last exhibition and where was it? And when do you want to hold your next exhibition?
I don't do exhibitions. I do launches. Last one - Air One at Oshkosh Airshow 2026.
Where does the design inspiration for your works come from? How do you feed your creativity? What are your sources of inspirations?
(1) Problems worth solving in real markets. (2) Constraints that force innovation. (3) Competitors I'm trying to beat. (4) First-principles physics. Inspiration from "nature" or "culture" is secondary. Inspiration from revenue is primary.
How would you describe your design style? What made you explore more this style and what are the main characteristics of your style? What's your approach to design?
Minimalist system design. Form is generated from performance, not imposed on it. Every curve, every material choice, every thickness serves function. The aesthetic emerges from ruthless optimization. No decoration. No trends. Timeless because it solves the problem completely.
Where do you live? Do you feel the cultural heritage of your country affects your designs? What are the pros and cons during designing as a result of living in your country?
Israel. Massive advantage. We're forced to solve hard problems cheaply and fast. No resources for waste. No time for consensus. No market for mediocrity. Everything we build competes globally from day one. The constraint is the competitive edge.
How do you work with companies?
As a strategic partner, not a service provider. We identify what you're trying to build, own the design and development completely, and partner on launch and commercialization. We take equity or retainer — not hourly rates. We move fast because we're invested in the outcome
What are your suggestions to companies for working with a designer? How can companies select a good designer?
Hire strategists who happen to design, not designers who happen to think strategically. Look for portfolio evidence of shipped, scaled products — not awards or aesthetics. Ask: "What business problems did you solve? What revenue did your design drive?" If they can't answer, they're not designing.
Can you talk a little about your design process?
(1) Define the problem in market terms, not design terms. (2) Research user behavior obsessively. (3) Generate constraints: cost, weight, manufacturing, regulation. (4) Prototype fast, test immediately. (5) Iterate toward manufacturability and market fit. (6) Launch, measure, optimize. Design is not finished until it ships.
What are 5 of your favorite design items at home?
I don't have a sentimental relationship with objects. My "favorite designs" are the ones I'm building next — aircraft, robotics, autonomous systems. The items in my house are functional. That's the compliment.
Can you describe a day in your life?
4:30am wake, run, think about the hardest problem in front of me. 6am with family. 7am email triage and decision-making. 9am-12pm focused design/engineering work or client calls. 12pm lunch, decompression. 1pm-5pm execution, coordination, problem-solving. 5pm-6pm strategic thinking on TMD/AIR roadmap. 6pm family. After kids sleep: reading (economics, strategy, physics), long-form thinking. Friday-Saturday: protected family time. Sunday: planning and synthesis.
Could you please share some pearls of wisdom for young designers? What are your suggestions to young, up and coming designers?
Stop calling yourself a designer. Call yourself a builder, a strategist, a problem-solver. Learn economics before aesthetics. Learn manufacturing before form. Learn your customer's business model before you touch a pencil. The best design career is one where you become indispensable to someone's revenue growth. Design aesthetic is worth zero if the product doesn't ship.
From your perspective, what would you say are some positives and negatives of being a designer?
Positive: Design is leverage. One person can reshape a category. Negative: Design is only leverage if it ships. Most designers never ship. Most never see the connection between their work and real profit. That gap is where most design talent is wasted.
What is your "golden rule" in design?
Form follows function. Function follows market. Market follows adoption. Adoption follows solving real problems better than alternatives. Start there.
What skills are most important for a designer?
Systems thinking. First-principles problem-solving. Manufacturing literacy. Business acumen. Speed. Ruthlessness in cutting anything that doesn't serve the core value. The ability to say "no" is more important than the ability to say "yes."
Which tools do you use during design? What is inside your toolbox? Such as software, application, hardware, books, sources of inspiration etc.?
CAD (Rhino, SolidWorks). Rendering (V-Ray). 3D printing and rapid prototyping. FEA and simulation. Cost modeling. Manufacturing process knowledge. Economics and pricing frameworks. Regulatory pathway mapping. And the most important: strategic clarity and first-principles thinking. Software is secondary to clarity.
Designing can sometimes be a really time consuming task, how do you manage your time?
Don't design when you're not in flow. Batch work. Protect focus time ruthlessly. Delegate execution to people who are faster at tasks than you are. Your job isn't to do design — it's to own the strategy and hold the quality bar. If you're in Rhino 8 hours a day, you're not scaling.
How long does it take to design an object from beginning to end?
Depends on the object. Concept to CAD: days. CAD to prototype: weeks. Prototype to manufacturing-ready: months. Manufacturing to market: varies wildly. For AIR ONE: 3+ years from early concept to FAA approval because of the regulatory pathway. For a smaller product: 6-12 months from concept to launch if you're moving fast.
What is the most frequently asked question to you, as a designer?
"Can you make it cheaper?" My answer: "Yes, if you're willing to sell less and make less margin, or if you're willing to change the specification." Good design doesn't start with cost — it starts with value. Cost optimization comes after.
What was your most important job experience?
Leading product strategy for advanced autonomous systems that required integration across government, defense, and commercial stakeholders simultaneously. Taught me that the hardest design problems sit at the intersection of regulatory approval, operational constraints, and stakeholder alignment. That experience is what prepared me to own the full product lifecycle at AIR.
Who are some of your clients?
AIR (eVTOL) - Head of Design, FAA-certified aircraft, 2,900+ pre-orders, commercial launch timeline. InTACT (Defense-tech) - Advanced autonomous systems, critical infrastructure protection, Israeli government partnerships. NuDay AI (Healthcare AI) - Co-founder, hospital validation pipeline. Multiple advanced mobility, aerospace, and robotics projects under NDA with commercial and strategic partners. Portfolio includes international commercial partnerships and next-generation transportation architectures.
What type of design work do you enjoy the most and why?
Transportation and aerospace systems where design directly impacts safety, adoption, and competitive advantage. Why? Because you can measure success. You ship, people buy it, competitors try to copy it, you iterate faster. That's the only feedback loop that matters.
What are your future plans? What is next for you?
1) Complete AIR ONE design fully and support through commercial launch. (2) Find my "Steve Jobs moment" — the life-changing product idea that I can't walk away from. (3) Build TMD into a billion-dollar design and innovation firm through IP ownership and equity partnerships. (4) Establish FORMA (AI design intelligence for transportation/aerospace) as the category-defining platform for next-generation vehicle design.
Do you work as a team, or do you develop your designs yourself?
Both. I lead teams on large projects. I work solo on strategy and early-stage concepts. The best setup: small strategic team, larger execution teams brought in as needed, ability to scale fast. No ego — only leverage.
Do you have any works-in-progress being designed that you would like to talk about?
Multiple next-generation aerospace and autonomous vehicle concepts in development phases. Advanced propulsion and autonomous system architectures under development with strategic partners. Cannot share specific details on timeline or partners until appropriate disclosure windows.

Any other things you would like to cover that have not been covered in these questions?
Design is not a career path — it's a tool for building wealth, creating categories, and reshaping markets. Use it as leverage, not as an identity. The designers who matter are the ones building billion-dollar companies. Everything else is noise.
