Build it now.
Build it right.

Founders hire me to tell them the truth early, while they can still do something about it: will anyone pay, will it work, can it be made at scale. Then I help them build it. Three-time CTO, 8 US patents, now building faster with AI.

Meet Reza, builder and catalyst

A catalyst speeds up a reaction without being used up by it. That is my job on a team: find the shortest path from first principles to a working product, and make everyone around it move faster. Do it fast, do it right. The world won't wait, and neither will your competitors.

My top 5 CliftonStrengths

  • Ideation. I connect ideas across fields and start from first principles, not from what everyone else does.
  • Competition. I measure the work against the best in the market, not against last year's version.
  • Activator. The catalyst part. I turn talk into a first prototype, fast.
  • Strategic. I see the routes early, dead ends included, and say so while there is still time to act.
  • Achiever. I finish. Zero mechanical build defects in production across three product generations.

My strongest domain is Influencing: I move people, not just parts. And I own the result. If it's mine, it ships. If it breaks, it's on me.

Today: Research Engineering Manager at WearTech Labs, Simon Fraser University's wearable technology facility, leading engineering and the industry side. Select hardware builds through New Element Research and Development.

How I help

Founders hire me for the first two. Investors hire me for the third. The rest I bring along. All of it starts with one question: will anyone pay for this?

  1. Venture Validation Sprint

    Exit Without Execution, applied.

    Thirty to forty-five days to prove or kill a venture thesis on paper: customer, funnel, pricing, revenue model and IP position, before you commit years and capital to building it.

  2. Fractional CTO

    Hardware from prototype to manufacturable product.

    The hardest phase of deep tech. Design for manufacturing, new product introduction, compliance, supply chain and the team to run it after me.

  3. Technical Due Diligence

    For investors and boards.

    An operator's read on a hardware company: what is real, what is a demo, what it will cost to reach volume, and which risks the deck leaves out.

  4. Founder Coaching

    The conversation nobody else will have with you.

    For founders who want a challenger, not a cheerleader. Positioning, validation, priorities and the habits that keep founders out of the 99% Club.

  5. AI Systems

    I also build the automation.

    Multi-agent pipelines, digital twins and automations wired into the tools a business already uses. Built to run in production, not to demo once. Often the fastest way to prove a thesis is to ship the thing.

What I think

Two frameworks on their way to becoming books, and one belief about speed.

“What founders hire me for: telling them what they do not want to hear, early enough to do something about it.”

Exit Without Execution

Validate the commercial thesis on paper first. Funnel, conversion, pricing, revenue, IP. Especially in hardware, where execution costs the most and a wrong thesis costs everything.

Framework in use. Book in development.

The 99% Club

A sarcastic name for the founders who follow the popular playbook (build big or go home, raise and burn) without asking how many people on that route ever arrive. Almost none do. Not a club you want to join.

Drawn from seven ventures. Book planned.

Stack and ship

Stacked strategies and stacked tools mean “I wonder” can become “here, take a look” in hours, not quarters. Fast start means slow and focused: do one small thing brilliantly, then compound.

How I work, every day.

Writing

Occasional pieces on intelligence, hardware, founders and what I am learning. Once in a while, not on a schedule.

Questions

Straight answers to what founders and investors ask before they book.

What does Reza Larimi do?

Reza Larimi is a hardware builder and catalyst based in Vancouver, Canada. Founders hire him to find out early, while there is still time to act, whether a product will sell, work and scale. Then he helps build it, from first principles and early prototypes to repeatable production, fast and without breaking what already works. He is a three-time CTO and co-inventor on 8 US patents, and uses AI to compress the design cycle. Today he leads engineering and the industry side at WearTech Labs, Simon Fraser University's wearable technology facility, and takes on select hardware builds through his practice, New Element Research and Development.

What is a fractional CTO, and when does a hardware startup need one?

A fractional CTO is a senior technical leader who works with a company part time, usually for a defined phase, instead of as a full time hire. In deep tech hardware the phase that needs one most is prototype to manufacturable product: design for manufacturing, new product introduction, compliance, supply chain, and building the team that runs it afterwards. Reza takes on that phase and hands over to the team he helped hire.

What is Exit Without Execution?

Exit Without Execution is Reza Larimi's framework for validating the commercial thesis of a venture on paper before building it. It tests the customer, the funnel, conversion, pricing, the revenue model and the IP position first. It matters most in hardware, where execution costs the most and a wrong thesis costs everything. The framework is in use with clients and a book is in development.

What is The 99% Club?

The 99% Club is Reza Larimi's sarcastic name for the founders who follow the popular startup playbook without checking the odds: incubator and investor advice, build big or go home, raise and burn. Almost none of them reach the destination that route promises, so it is not a club you want to join. The point is to choose your route on purpose and read the early signals, real customers and real cash. A book is planned.

What is a Venture Validation Sprint?

A Venture Validation Sprint is a thirty to forty-five day engagement that proves or kills a venture thesis on paper, before the founder commits years and capital to building it. It applies Exit Without Execution to one venture: customer, funnel, pricing, revenue model and IP position, with a clear go or no-go at the end.

Does Reza Larimi do technical due diligence for investors?

Yes. For investors and boards he provides an operator's read on a hardware company: what is real, what is a demo, what it will cost to reach volume, and which risks the pitch deck leaves out.

What is Stack and ship?

Stack and ship is how Reza works every day. Stacked strategies and stacked AI tools mean an idea can become a working thing to look at in hours rather than quarters. The rule behind it is to start small and focused, do one thing brilliantly, then compound.

What is Book to Blueprint?

Book to Blueprint is Reza Larimi's YouTube channel. Each episode turns one book into one actionable blueprint in under ten minutes, covering founder and operator books, personal development and strategy. Episodes at youtube.com/@reza-larimi.

What is Reza Larimi's background?

Seven ventures and three CTO seats, eight US patents covering sensors, test beds and methods, and an alumnus of Entrepreneur First in Toronto. Roles include CTO and co-founder of ForthGrid and of Orchard Technologies, CEO and co-founder of GutPlans, R&D product lead at Global Heat Transfer, and research assistant at the University of British Columbia in stretchable sensors, adaptive control and robotic hands.

What are Reza Larimi's strengths?

His Gallup CliftonStrengths top five are Ideation, Competition, Activator, Strategic and Achiever, and his strongest domain is Influencing. In practice he connects ideas across fields, measures the work against the best in the market, turns talk into a first prototype fast, flags dead ends while there is still time to act, and finishes what he starts.
