Build the team.Ship the product.
I'm Spyros Zafeiropoulos, an engineering executive with 12+ years in autonomous driving and robotics. Through STEPS, I help engineering leaders and deep-tech startups get from working prototype to shipped product, and build the organization that gets them there.
01 — Who I work with
Does any of this sound familiar?
A
You just stepped up to leading managers.
The job changed overnight. The playbook that got you here doesn't cover it.
Leadership coaching →B
The prototype works. The path to product doesn't.
The demos impress, but every date slips and nobody can say what "done" means.
Founder advisory →C
The team doubled. Delivery didn't.
More people, more meetings, the same output. The structure hasn't caught up with the headcount.
Fractional leadership →D
The board wants engineering metrics you can't give yet.
You know the team works hard. You can't yet show where it's heading, or how fast.
Founder advisory →02 — How I help
Three ways to work together
For engineering leaders
Leadership Coaching
For managers, directors and VPs stepping into a bigger role: the judgment, systems and presence it asks for.
3 months · bi-weekly 60-min sessions
See the details →For deep-tech startups
Fractional VP of Engineering / CTO
For seed to Series B teams of 10–80 engineers: the org, the execution system and the path from prototype to shipped product.
Starts with a 2–3 week Engineering Org Review
See the details →For technical founders
Founder Advisory
A seasoned sounding board on the hard calls: technical strategy, first leadership hires, the story for your next raise.
Monthly session + async access

03 — In practice
What this has looked like before
Venture-backed autonomy startup
12 → 65+
engineers in two years
What I did
Structured the org into dedicated teams (autonomy & AI, software platform, safety & systems, simulation, product & program), hired directors and senior staff engineers, and built continuous feedback and performance reviews.
Global algorithms organization
140 → 250+
engineers across 7 sites in 18 months
What I did
One algorithm product strategy across ~10 customers and ~20 projects, a new data science & simulation team, and a V-cycle + Agile release process.
Delivery
50% → ~100%
on-time project delivery
What I did
OKR-driven technical product strategy and hands-on Scrumban project management. Key decisions went from days to hours.
