  • This Site Was Built in One Day. Here Is the Honest Log.

    This website went from a domain search to what you are reading in one working day — July 10, 2026. In the spirit of the verification standard this site runs on, here is the honest log of what was built, by whom, and how.

    What got built

    • A full brand audit — the “Magic Berry Plan”: 15 pages built on Dennis Yu‘s published frameworks. Three AI research agents pulled 200+ live sources, separated every claim into verified / reported / not found, and scored my personal brand honestly (28/100 at baseline — no Knowledge Panel, scrapers owning half of page one, and a campus business with zero public pages). The plan includes a 14-item fix sprint, a Topic Wheel, a Dollar-a-Day amplification budget, and a 90-day scoreboard.
    • An eight-agent operating system — skill files for a daily reputation monitor, weekly prospect research, warm-path mapping, ad optimization, operator recruiting, a Friday metrics loop, and a monthly honesty audit that re-verifies every public claim I make. Nothing publishes or sends without my approval; the rules live in the files, not in vibes.
    • This website — domain registered, DNS pointed, WordPress provisioned on BlitzMetrics‘ platform, and 6 pages plus 22 sourced posts imported, with Person and Organization schema underneath so machines can read the record too. Built to the entity-home standard Dennis’s team documents publicly.

    The part worth copying

    The most valuable artifact isn’t the site — it’s the banned-claims register. There are stories about my background that circulate in rooms I’ve been in. The agents checked them against the public record, found no sources, and locked them out of every page here until documentation exists. That stung, briefly. But in a world where your buyers run diligence with AI, a brand that audits itself is the only kind that compounds. Same standard as the mentions tracker →

    Credit where it’s due

    The system is Dennis Yu’s, published openly at blitzmetrics.com and Local Service Spotlight. The build was run by AI agents operated from Dennis’s team, including Leo Pohlmann in Cologne, whose own site was built the same way — the method proves itself on the people who run it. A fuller engineering write-up will publish on blitzmetrics.com.

    Photos and video from the campus work are the next thing that lands here. If the pages still show placeholder frames, that’s why — real footage only, per the house rule.

  • Why This Site Exists: An Entity Home, Not a Portfolio

    This site launched in July 2026 with one job: to be the entity home for “Justin Sonnenreich” — the single canonical place that states, with sources, who I am, what I’ve built and where else I exist online.

    Why bother? Because in 2026 your first impression is compiled by machines. Google’s Knowledge Graph, ChatGPT, Perplexity — they assemble “you” from whatever’s most structured and consistent. Before this site, the top results for my name included data-scraper profiles and a duplicate LinkedIn. Strangers were writing my record. The fix is boring and it works: one homepage that says everything unambiguously, an About page with a sourced timeline, posts that document real work (cases, projects, credit to mentors), Person and Organization schema underneath, and a hard rule about verification.

    Built on the personal-brand-website system Dennis Yu’s team documents publicly — the same process behind sites like michaelkrigsman.com. If you’re a founder whose Google page 1 is scrapers: fix it before your next fundraise or enterprise deal. Your buyers’ agents are reading.

  • Everything Brands Ask Before a Campus Pilot

    Collected from real calls, answered without the meeting. What exactly do we pay for? A verified action we define together pre-launch — funded account, KYC-passed signup, activated subscription. Per result. How do we know the numbers are real? Unique tracking per operator/shift, reconciled against your own dashboard — you audit us. Which campuses? Where we have trained operators, or where we recruit one for you (one cycle of lead time — how operators work). Who’s liable on campus? Activations run within campus rules; we don’t do guerrilla stunts that spend the trust we sell. Do you work with anyone? No: gambling/sports betting, alcohol and nicotine are excluded, permanently. What does it cost? Depends on the action’s value to you — the math shows the range logic; the rate card is one email away. How fast? Existing operator: weeks. New campus: a recruiting cycle. Semester rhythms rule everything — move-in week is the Super Bowl.

  • The Frameworks I Actually Use (and Where They Come From)

    Five frameworks run most of what I do. None of them are mine; all of them are linked to their source. 1. The Topic Wheel (Dennis Yu): WHAT you sell in the center, HOW-expertise around it, WHY-stories outside — people discover you from the outside in; this site’s structure is a Topic Wheel. 2. Dollar-a-Day (BlitzMetrics): boost candidates $1/day for 7 days, kill the bottom 90%, scale unicorns — amplification with quality control. 3. The Content Factory: Produce, Process, Post, Promote — every activation, talk and win becomes a compounding proof library. 4. MAA — Metrics, Analysis, Action — the Friday loop; metrics without analysis is a screenshot, not a report. 5. LDT — Learn, Do, Teach — the status ladder for our operators: levels are earned, never negotiated, and teaching is the top.

    Steal them from the sources, not from me — that’s what the links are for. Why I credit everything →

  • The Ecosystem Behind MarkitAds: Launch Chapel Hill and 1789

    When agency websites say “award-winning,” ask which award. Here’s our honest version: MarkitAds grew up inside the UNC Chapel Hill entrepreneurship ecosystem — Launch Chapel Hill, the venture accelerator, and 1789 / Innovate Carolina, the university’s founder community.

    What that actually gave us: structured mentorship from operators who’d done it before; deadline pressure with demo days attached; a bench of advisors (including from the University of Wisconsin network) who still answer my calls; and the campus-insider view of how universities think — which became a real asset when UNC itself became a client.

    For student founders: your university’s accelerator is the cheapest leverage you’ll ever get. Take every office hour. It’s a large part of why a bedroom company survived to become a real one.

  • What a Policy Internship Taught a 17-Year-Old Marketer

    In 2020 I interned in political affairs at The Borgen Project, the nonprofit that mobilizes public support for US leadership on global poverty.

    Advocacy work is distribution work with the varnish off. Nobody buys anything; you’re moving attention and pressure — calls to congressional offices, local op-eds, constituent meetings. You learn that mobilization beats persuasion: the win isn’t changing a mind, it’s activating the people who already agree but would never act unprompted. You learn that a specific ask (“call this office, say this sentence”) outperforms a passionate case every time.

    Swap “constituents” for “students” and that’s a campus activation: find the aligned people, lower the friction to one specific action, verify it happened. I was 17 and thought I was taking a detour from marketing. It was the most marketing thing I ever did.

  • Model UN President to Agency Founder: Why Debate Skills Sell

    From 2020 to 2022 I was president of the Montgomery County Model UN team. It sounds like résumé filler. It’s the training I use most.

    Model UN teaches three things agencies get paid for: speaking to a skeptical room off five minutes of prep; writing position papers — which is to say, turning a mess of facts into one defensible argument (every PR pitch is a position paper); and coalition math — knowing that resolutions pass in the hallway, not at the podium, which is exactly how campus distribution works too.

    If you’re a student reading this: the clubs where you argue, organize and recruit are pre-professional training that the “practical” clubs can’t match. We hire from them deliberately.

  • Building a Team of Twelve Before 25

    MarkitAds is roughly twelve people: engineering under CTO Troy Smith, growth under our VP of Growth, revenue operations, content, and the campus activation staff — the ambassadors, associates and activation leads who make the field work actually happen.

    What I’ve learned managing a company where I’m often the youngest person with the final say: 1) Write everything down — authority you have to re-explain is authority you don’t have; the playbook is the boss so I don’t have to be. 2) Hire operators, then give them territories (this applies to executives exactly as it does to campus operators). 3) Pay on results wherever results are measurable; it removes 80% of the awkward conversations. 4) The founder’s job migrates from doing, to selling, to making the record sell — which is what this whole site is for.

    Advisors from the Launch Chapel Hill / UNC ecosystem and from the University of Wisconsin network round out the bench. More on the ecosystem behind us.

  • What Dennis Yu Taught Me About Letting Reputation Do the Selling

    Everything about how this site is built — and a lot about how I now run MarkitAds — traces to Dennis Yu, who has spent years teaching founders that reputation should do the first three touches of every sale.

    The frameworks, credited: the Topic Wheel (people discover you story-first, expertise second, offer last — this site’s blog is literally organized that way); the Dollar-a-Day strategy (amplify only what already works, kill the rest without sentiment); the Content Factory (capture everything, process it into proof, publish, promote); and MAA — Metrics, Analysis, Action — the weekly loop that keeps it honest (“analysis is 10x more important than metrics”).

    The deepest lesson is the standard behind the mentions tracker his team built for me: if a claim can’t survive verification, it doesn’t ship. A super-connector’s instinct is to sell with charm; Dennis’s discipline is to make the record sell first, so charm only has to close. I’m 23; having a mentor whose SOPs are public means anyone can check whether I’m actually running them. Good. That’s the point.

  • A Semester at Waseda: What Tokyo Taught Me About Markets

    In 2023 I spent a semester at Waseda University in Tokyo, away from UNC and away from the American default settings of how business works.

    What stuck wasn’t the classroom. It was watching distribution executed at a level Americans don’t believe exists: konbini supply chains that restock three times a day; vending machines profitable in places no US operator would service; retail staff treating a ¥150 purchase with the ceremony of a luxury sale. Japan runs on the compounding of small, reliable, verified interactions — trust as infrastructure.

    That’s the standard I brought back to our campus operations: the table is clean, the pitch is honest, the operator shows up on time, every signup is real. Reliability at small scale is what permission to scale looks like. (Also: the best marketing conversation I had that semester was with a vending-machine restocker. Talk to operators.)
