  • 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.)

  • The Student Operator Model: Run Your Campus Like a Startup

    The phrase “brand ambassador” recruits the wrong people. We recruit for a different job: run your campus like a startup.

    The proof this works is all over the market: Fresh Prints’ campus managers average $2–3K a semester running real apparel businesses (top operators clear $40K/yr); Fizz pays ambassadors per verified signup and recruits with the same entrepreneurial frame; Storage Scholars built a ~$7M student-run logistics company on 175 campuses. Students will run a P&L, if you hand them four things.

    • Territory: one campus, exclusively yours.
    • Playbook: the full MarkitAds SOP set: activation ops, tracking, verification, capture.
    • Comp curve: base pay for activation days + revenue share on every verified account from your campus + a semester bonus for hitting target.
    • Status: a ladder that’s earned, never negotiated: certify on the SOPs, hit targets, then train the next operator and unlock a bigger share. The best operators become regional leads.

    For students: it’s the highest-leverage résumé line on campus that pays you while you build it. For brands: it’s why our CPA holds, owners perform where gig workers coast..

  • Why Students Are the Most Undervalued Growth Channel in America

    The numbers, from public sources: US back-to-college spending was estimated at $88.8 billion (NRF, 2025); there are roughly 19 million US college students (SheerID/NCES); and the weeks around move-in are when a person opens their first bank account, first brokerage, first delivery subscription, the habits that persist for decades.

    Meanwhile, digital CAC keeps inflating (average e-commerce CAC $68–84; CPMs up ~20% year over year, estimate), and Gen Z is the demographic most likely to be unreachable there anyway: ad-blocked, feed-skeptical, and trained to trust peers over polish.

    So why is campus still undervalued? Because it doesn’t scale like a slider. It requires humans, logistics, and semester rhythms, operational advantages, not media-buying advantages. That’s precisely why it stays cheap: the brands that treat campus as an ops problem (staffing, tracking, verification, operators with territories) buy customers at prices the feed hasn’t seen in a decade. The math is here: what a $5 verified account means.

  • How a Campus Activation Actually Runs: Staffing, Tracking, Verification

    Brands imagine a campus activation as a folding table and some free merch. Here’s what’s actually running underneath when it’s done professionally.

    Staffing

    A trained student operator owns the campus; ambassadors staff the table in shifts around their class schedules. Everyone has been through the playbook: pitch scripts, compliance rules (no misleading claims, no signup pressure, IDs where age matters), and capture duties, every activation is also a content shoot.

    Tracking

    Every operator gets unique links and codes per location and shift. That gives the brand attribution to the table, the day, and the person, which is how per-result pricing stays honest, and how we learn which spots on which campuses convert (dining hall > quad, Tuesday > Friday, move-in week > everything).

    Verification

    The number we invoice is the number that survives checks: the action is defined pre-launch (funded account, KYC-passed signup, activated subscription), our dashboard is reconciled against the brand’s, and anomalies get investigated before anyone bills anything. A person watching the signup happen is the part that is hardest to fake, which is the point of the CPA math.

  • Community Musician: Seven Placements in Eight Months for Scott Arey

    Not every client is a university or a beauty empire. Community Musician, Scott Arey’s brand, is what most of the economy actually looks like: one person with deep expertise and zero media presence. In eight months, MarkitAds earned seven placements for him.

    Scott recorded a video testimonial about the engagement, one of two client videos we point to (the other is Emil Runge’s). We don’t paste text quotes onto case studies; video, in the client’s own voice, or nothing.

    The playbook for a solo brand is the same one we use for founders: mine the stories (Scott had years of them), match them to outlets that need exactly that story, and publish the proof so each placement makes the next one easier, the flywheel Dennis Yu teaches.

  • Selling Sneaker Intel at 16: The Boosted Notify Story (and the 2019 Exit)

    My first company existed because sneaker drops are rigged in favor of people who understand systems. At 15 I was studying release mechanics, bot detection and raffle math the way other kids studied box scores. At 16 that became Boosted Notify: a consulting service helping clients purchase limited, high-end sneakers, over 80 clients a month at peak.

    In 2019 the business was acquired by the COOKLAB Group, an operator in the sneaker-tooling ecosystem. (Founder’s account; sourced on my LinkedIn; acquirer confirmation will be linked when live.)

    Three things stuck. Markets where demand outstrips supply reward whoever understands the allocation mechanism, that’s most of marketing. Recurring service revenue from a problem people actually have beats one-time flips. And when your edge becomes a product category (bots, monitors), sell to someone who wants to own the category. The pattern repeated with Mission: Mentor, and it’s why MarkitAds prices per verified result: I like businesses where the value is checkable.

  • Reputation Repair, Documented: Six Placements for KORR Value

    Reputation repair is the assignment agencies love to sell and hate to document, because the work is delicate and the client rarely wants attention on the “before.” KORR Value let us document it: six earned placements secured through MarkitAds‘ outreach engine. The case study is live at markitads.com/our-work/korr.

    The rules we follow on repair work

    • No astroturf. Every placement is coverage in an outlet that chose to run it, earned with a story that was true: no pay-for-praise, no fake reviews, ever.
    • Fix the substance first. If the underlying complaint is valid, PR without operational change is a delay, not a repair. We say so upfront.
    • Build the positive record, don’t fight the negative one. Search results improve when there’s more true, substantial, well-sourced material about the good work: the same same standard of proof.

    Why show this next to campus work? Because they’re the same product at different altitudes: a reputation is a supply chain of verifiable moments. For a brand on campus, every activation is a reputation event witnessed by hundreds of students. Run it honestly and it compounds; run it cynically and the group chats will do the repair assignment on you. We build for the first case.

  • I Started MarkitAds at 16. Here’s the Honest Version.

    How it started

    I started MarkitAds at 16, in Bethesda, Maryland, because Boosted Notify had taught me something surprising: businesses will pay a teenager if the teenager solves a problem and answers email faster than the adults. I was not a prodigy. I was available, specific, and relentless about follow-up.

    The early agency did whatever legitimate work was adjacent to attention: press outreach, social growth, lead generation. Some months were great; some clients taught me expensive lessons about scope creep and about promising outcomes I couldn’t control. The thing that compounded wasn’t a niche, it was documentation. Every engagement became a checklist; every checklist made the next engagement faster. Years later I’d learn Dennis Yu teaches exactly this as doctrine: repeatable excellence beats heroics.

    Where it stands

    Today MarkitAds is a team of roughly twelve running two lines: PR and lead generation (client placements have included USA Today, The Washington Post and Fox 5; live links pending), and the campus activation network, the business I believe is the company that matters. In between: Mission: Mentor, 10,000 students, an acquisition by Crimson (acquirer confirmation in progress), a degree path at UNC Chapel Hill and a semester in Tokyo.

    The claims on this page are sourced on my LinkedIn profile, and I hold myself to the same standard: if I cannot source it, I do not say it. What I’ll say without a source, because it’s an opinion: starting at 16 wasn’t brave. Staying honest about what actually worked is the hard part.

  • URBN Market: 0 to 10,000 Followers, a Washington Post Mention, and a Fox 5 Segment

    Big-brand logos are nice, but local businesses are where PR either works or visibly doesn’t, there’s no residual fame to hide behind. URBN Market came to MarkitAds at a standing start.

    What happened

    • Social presence grown from zero to 10,000 followers
    • A mention in The Washington Post
    • A segment on Fox 5

    Full case study: markitads.com/our-work/urbn-market.

    The mechanics, briefly

    Earned media for small businesses is a matching problem: reporters need specific, local, timely stories; businesses have them but don’t know which ones count. The engine is unglamorous, story mining, tight pitches, fast follow-up, and content that makes the coverage compound instead of evaporating. The same “capture everything, publish the proof” discipline Dennis Yu drills applies at every size.

    Why it matters here: campus brands are local brands. Every activation we run happens in a town with a business journal, a campus paper and a local TV station, and coverage there feeds the flywheel: activation → content → coverage → easier next activation.

  • Mission: Mentor, What 10,000 Students Taught Me About Campus Distribution

    In 2021, while running MarkitAds, I co-founded Mission: Mentor, a nonprofit edtech with one idea: college guidance shouldn’t be a luxury good. Private counselors charge thousands of dollars for what is, mostly, structured information and accountability. We built a free virtual college counselor to deliver both.

    What we built

    A volunteer team that grew past 30 people. A platform that walked students through applications, essays, scholarships and financial aid. And reach: more than 10,000 students used it before the company was acquired by Crimson in September 2022. (Stated as my founder’s account; sourced on my LinkedIn; acquirer confirmation will be linked here when live.)

    How it actually grew

    We had no ad budget worth mentioning. Growth came from watching how information actually moves through a school: one counselor recommends it to a class; one senior posts it in a group chat; one club president puts it in a newsletter. Campus distribution is a graph of a few hundred high-trust nodes, RAs, club presidents, team captains, TAs, and if you win them, you win the campus for free. If you don’t, no budget saves you.

    That map is the intellectual foundation of MarkitAds’ campus network today: operators are chosen for their position in that graph, not for their follower counts. Mission: Mentor was the research project; the activation business is the productization. And the mission stuck with me too, a meaningful share of the students we serve now get their first paid work experience running our activations. Full story.
