About BlackTitan

I’m David Martinelli, a guy from a regular neighborhood who turned $10,000 into a business machine worth north of half a billion dollars. No silver spoon, no magic lamp, just crazy focus, hard work, and the guts to move when others froze. Today I run BlackTitan, buying steady companies, funding new ones, and showing owners how to squeeze every drop of value out of their work.

But let’s rewind. Ten grand in my bank was all I had. Instead of playing it safe, I dumped it into a small venture I believed in. While friends were busy “waiting for the right time,” I was signing deals, knocking on doors, and learning on the fly. Year after year that seed money grew. First to six figures, then seven, and it just kept compounding. The secret wasn’t luck, it was doing the boring stuff everyone else skips: tracking numbers, fixing leaks, hiring killers, and reinvesting like a maniac.

As wins stacked up, I spotted a bigger play. There were good companies out there, solid cash flow, loyal customers and yet nobody paid attention because they weren’t flashy. I knew if I could grab them, tighten operations, and pour in smart marketing, we could rocket their value. That idea became BlackTitan: we buy, fund, and scale overlooked businesses faster than most folks think possible.

I also found out success is a team sport. So I built The Brotherhood Vault, a private circle where serious operators push each other higher. We swap tactics, kill bad habits, and share deals before they hit the street. If you’re in that room, you’re family, and families don’t let each other play small.

People ask what drives me. Simple: I hate wasted potential. Whether it’s a company stuck in neutral or a dreamer scared to jump, untapped talent bugs me. My mission is to flip the switch, turn “maybe one day” into “done deal.” That’s why I spend as much time coaching and investing in others as I do building my own stack.

Look, I’m still climbing. There’s always a bigger mountain. But I’ve learned a few truths worth passing on:
