About

I build, test, and ship — then double down on what works.

I’m Hami Tahm, a serial tech founder based in Toronto. Over 12 years and roughly fourteen ventures across two markets, I’ve learned what works and what doesn’t. Today I build HomeCalc.caand help Canadian businesses get found in ChatGPT, Perplexity, and Google AI Overviews.

01The short version

I’m Hami Tahm, a tech entrepreneur focused on building and testing scalable digital products across multiple industries.

Over the past decade, I’ve launched and operated ventures across marketplaces, marketing, and AI-driven platforms — with a focus on speed, iteration, and real-world validation.

I don’t chase ideas — I validate them. I’ve learned that most ideas fail not because they’re bad, but because they’re not tested fast enough or killed early enough.

Now, I’m focused on identifying one breakout opportunity — a product that can scale globally and become a category leader.

I’m especially interested in:

AI-driven products · Platforms with strong distribution loops · Businesses that can scale beyond geography

If you’re building something ambitious or thinking globally, let’s connect.

02How I work
01
Build fast
Ship the smallest real version, this week. Plans don’t survive contact with users — products do.
02
Test aggressively
Let the market, not the roadmap, decide what’s true. Real signal over comfortable assumptions.
03
Kill what doesn’t work
No sunk-cost loyalty. A clean shutdown frees the resources the next bet needs.
04
Double down on what does
When something works, concentrate everything on it. Focus beats spreading thin every time.
