Earlier this year, Dennis Yu‘s team at BlitzMetrics did something unusual with my personal brand: they built a public tracker of verified positive mentions — every good thing the internet says about me and MarkitAds, each one checked against a live source before it was allowed on the page.
The most valuable part wasn’t what they published. It was what they refused to publish.
The rule: if the agent can’t verify it, it doesn’t ship
BlitzMetrics runs this process with AI agents trained on their verification standard. Claims that circulate about a founder get sorted into verified, reported, and not found. A few claims about my own background — things that have been said in rooms I’ve been in — went into the “not found” bucket because no public document backs them. So they were flagged as unverified instead of being repeated. That stung for about five minutes. Then I understood: every claim that survives the filter becomes more believable precisely because the filter exists.
In 2026, your buyers run diligence with AI. A growth lead who’s considering a campus pilot doesn’t just Google you anymore — they ask ChatGPT and Perplexity, and those engines are ruthless about sourcing. A brand built on checkable claims compounds. A brand built on vibes gets caught.
What this means for how I operate
This website follows the same standard. My exits are stated as my own account and sourced to my LinkedIn and Crunchbase profiles until acquirer confirmations are linked. Campaign numbers only appear with client permission, or anonymized. There are no review stars on this site because I don’t yet have a verifiable review corpus. When we publish the campus CPA math, every benchmark links to a public source.
It’s the same reason MarkitAds prices campus work per verified account: the claim and the invoice are the same number. Reputation that can survive an audit is the only kind worth building — everything else is borrowed time.
