The cheapest way to sell an online course is to market to the end user rather than the buyer, then let the user sell the buyer for you. Kalyan Mazumder built Prepmedians, an SAT and ACT prep platform taught through sketch comedy with Broadway actors, by acquiring teenagers organically on TikTok and having those teenagers ask their parents to purchase.

In this episode I sat down with Kalyan Mazumder, a Yale theater and psychology graduate who acted off-Broadway while tutoring, then built a company around the observation that students who could not memorize a quadratic formula could memorize a Drake song.

Below is the whole playbook: the TikTok content strategy including the watch-time hack, the free-trial funnel that converts curiosity into email capture, why marketing to students beats marketing to parents, pricing, and how the B2B nonprofit channel works alongside it.

Key takeaways

• Market to the user, not the buyer. Kaplan and Princeton Review pay enormous acquisition costs chasing parents. Teenagers are reachable organically.
• 350,000 TikTok followers, ~200,000 views per post. The primary acquisition channel.
• The 5-7 second watch-time hack. Dense on-screen text takes 20 seconds to read, so the video loops five times.
• Withhold quiz results until email capture. Students take a test, watch a lesson, retake it, then must sign up to see improvement.
• 2.5x more effective than Khan Academy in pilot testing. With a 9% score increase from watching a single video.
• Spell “link in bio” wrong on purpose. Correct spelling gets the comment suppressed.
• Pricing: $99/month or $299/year. The annual pays for itself in three months, which pushes people toward it.
• Brand equity over short-term sales. During 2020-2021 he told students who should NOT take the SAT.

Why market to students instead of parents

Marketing to the student rather than the parent is the core strategic decision behind Prepmedians. Kaplan and Princeton Review spend heavily acquiring parents because they sell high-lifetime-value tutoring and classroom services that justify the cost.

A software-only product has a much smaller lifetime value, which means acquisition cost has to come down proportionally. Teenagers can be reached organically on TikTok at effectively zero cost, and parents cannot.

The sequence: a student finds the TikTok, tries the free module, sees their score improve, and enters a parent’s email. The parent receives an email showing their kid rated the product 5 out of 5 on both entertainment and education, while the kid is separately asking for it.

A parent hearing their teenager ask for SAT prep is a very different sale from a cold ad. The student becomes the sales rep.

The free trial funnel that captures emails through curiosity

The free trial funnel converts by withholding results until the student provides contact information, using curiosity and sunk cost rather than a hard gate.

The exact sequence: the student takes a pre-video quiz, watches the comedy lesson module, then retakes a randomized quiz. At that point they have invested about twenty minutes and genuinely want to know whether they improved. Seeing the results requires entering their information.

The improvement is real, which is what makes it work. Pilot testing showed a statistically significant 9% increase from watching a single video once, with questions randomized before and after so the deck is not stacked.

Two different paths by device. Mobile visitors from TikTok get a short signup form immediately, because their attention span is short and the priority is capturing information before they leave. Desktop visitors who arrived by searching get to go through the full module first, because they have ten to twenty minutes and higher intent.

The TikTok watch-time hack that triggers the algorithm

TikTok’s dominant ranking signal is watch time, and a five-to-seven second video with dense on-screen text exploits it. Reading the text takes about twenty seconds, which means the video loops four or five times and registers as extraordinarily engaging.

Kalyan’s format: a trending sound (a Thanos clip, for example), a face effect, a character he has built, and a math fact or shortcut as the text. Seven seconds of video, twenty seconds of reading.

The same logic explains why he does not put calls to action inside the video itself. Anything that reduces watch time reduces reach, so the CTA lives in the caption and a pinned comment instead.

How to write TikTok captions and comments without getting suppressed

Writing “link in bio” correctly spelled in a TikTok comment gets that comment suppressed so students never see it. The workaround is deliberate misspelling: “Lynk in b1o” rather than the correct form.

The full setup that works: a properly spelled call to action in the caption, a deliberately misspelled version in a pinned comment, and a bio that says “11th graders, click the link” with arrows pointing down.

Withholding what is behind the link outperforms describing it. An eleventh grader seeing “11th graders click the link” wants to know what is there. Explaining it first removes the reason to click.

Worth knowing: TikTok’s search now indexes spoken words in videos, not just captions and on-screen text, so audio mentions of URLs can trigger the same suppression.

The three pinned videos for cold, warm, and hot audiences

Prepmedians pins three videos to the top of the TikTok profile, each aimed at a different awareness level.

• Cold audience: the product trailer, which explains what this is to someone who just arrived.
• Warm audience: a testimonial, for someone who understands the concept and needs proof.
• Hot audience: the most viral video (7.2 million views), which carries the strongest social proof.

The link in bio goes to a Beacons page with the trailer embedded and a single glowing button reading “click to start a free trial, no credit card needed, boost your score instantly.” That page also carries a low-commitment email capture for people who bounce before the trial.

The signup page converts at roughly 33%.

Why building brand equity beat chasing sales in 2020

During 2020 and 2021, when SATs were being canceled and going test-optional, Kalyan deliberately published content that hurt short-term sales in order to build trust.

Instead of insisting students still needed to take the SAT, he published honest guidance about who should take it, who should skip it, what to do with scores, and how to think about prepping. Some of that actively discouraged purchases.

The payoff came later. Students who watched the company be honest during that period trust it, and they refer younger siblings and friends. He is seeing that referral effect now.

The underlying tension he names: on TikTok there is a constant pull between what goes viral and what builds an audience that actually buys. Creators with far more followers and views than him are not monetizing, because the depth of trust is not there.

Why teenagers are the hardest audience to make content for

Teenagers are the most critical audience on the planet for entertainment quality, which is why successful K-6 education companies deliberately avoid the high school market. Kalyan asked several of them directly and was told it is too difficult to make a teenager laugh without landing as corny.

That difficulty is the moat. Prepmedians invested heavily in high production value with Broadway actors and sketch comedians, which is expensive and precisely what competitors will not do.

The alternative without funding would have been a Weebly site or YouTube channel with iPhone footage and a few wigs. Other people are doing that version, and it has not converted.

The content library was the single largest expense, ahead of the six-figure software build.

How the education-plus-entertainment approach actually performs

Prepmedians tested 2.5 times more effective than Khan Academy in pilot studies, with a statistically significant 9% score increase from a single video view, rising as students review.

Student ratings run 4.8 out of 5 on entertainment, which is remarkable for teenagers rating an educational product.

The origin of the approach was noticing that students who could not memorize a quadratic formula could memorize a Drake song or a scene from a Seth Rogen movie. Teaching the quadratic formula as a Drake rap worked immediately.

The measurement mechanism was built into the platform from the start: pre-video quiz, video, post-video quiz, with randomized questions. That is also how he raised money in stages, starting with $300,000 and continuing to about $1 million once the efficacy data existed.

Course pricing that pushes people toward the annual plan

Prepmedians prices at $99 per month or $299 per year, with a 10% discount code sent to parents in the post-trial email, bringing the effective prices to roughly $90 and $270.

The annual plan pays for itself in three months, which is the deliberate design. A student who thinks they might take the March SAT and possibly the June one does the math and takes the year.

The benchmarking was against other online-only SAT and ACT programs, some of which run up to $400. The target was competitive pricing that stays accessible to most families.

Purchase zip codes span roughly the top 40-50% of income. The lower half is reached through nonprofit and public school partnerships, which is how the social mission and the business model coexist.

How the B2B nonprofit and school channel works

The B2B channel sells to nonprofits and public schools, which funds access for low-income students. Selling into it works through conferences and warm introductions rather than cold outreach.

Kalyan built a sales team to cold-call schools and found it largely ineffective, because the actual decision makers are not the people who answer the phone. Meeting decision makers directly at conferences worked far better.

For nonprofits, the pattern is a warm introduction to a local chapter, a pilot study demonstrating efficacy, then referrals from that chapter to affiliates nationally.

Business-to-consumer currently generates more revenue than B2B.

When an MBA is worth it for an entrepreneur

Kalyan’s assessment is that an MBA is worth it for network and capital access, and not for the skills themselves.

He needed roughly $1 million in seed funding for a high-fixed-cost product (six-figure software plus a professionally produced content library), and coming from a New York acting career he had no network to raise from. The MBA network is where that money came from.

The skills are available far more cheaply through podcasts, YouTube, and self-study. His framing for anyone asking: what are you building, and what do you need from the degree?

Capital and network, or a career switch into consulting or banking, justify it. Skills alone do not.

Frequently asked questions

How do you sell an online course to teenagers?

Market to the student rather than the parent. Teenagers are reachable organically on TikTok at near-zero cost, while parent acquisition is expensive. Get the student to try a free module, see real improvement, then have them provide a parent’s email so the parent receives proof alongside their kid asking for it.

What is the TikTok watch-time hack?

A five-to-seven second video with dense on-screen text that takes about twenty seconds to read, so the video loops four or five times. Watch time is TikTok’s dominant ranking signal, so the loop registers as exceptional engagement and pushes the video further.

Why do TikTok comments with “link in bio” get suppressed?

TikTok blocks comments containing correctly spelled promotional phrases. The workaround is deliberate misspelling like “Lynk in b1o.” Put a properly spelled call to action in the caption instead, and keep it out of the video itself since it reduces watch time.

How do you capture emails from a free trial?

Withhold the results. Have the user take a pre-lesson quiz, complete the lesson, retake a randomized quiz, then require signup to see whether they improved. Curiosity plus twenty minutes of invested time converts far better than a gate at the start.

Should you build brand trust or chase sales on social media?

Trust compounds. During 2020-2021, Prepmedians published content telling students who should skip the SAT entirely, which hurt short-term sales and built a referral engine. Creators with much larger followings frequently fail to monetize because that depth of trust is missing.

How should you price an online course subscription?

Prepmedians charges $99 monthly or $299 annually, so the annual plan pays for itself in three months. That gap pushes buyers toward the annual commitment. Benchmark against comparable online-only competitors and stay accessible to your actual market.

Is an MBA worth it for entrepreneurs?

It depends what you need from it. For raising significant capital without an existing network, or for switching into consulting or banking, it is genuinely valuable. For the skills alone, podcasts and self-study cost dramatically less and teach the same material.
