12 tactics from Cliff Weitzman
Creative App Marketing Strategies — Cliff Weitzman, Speechify
Watch the full episode“If you didn't have dyslexia you're like see a guy see a buddy. But if you had dyslexia you try five times because you're not gonna read the book by yourself and after the fifth time it works. To this day 15% of the reviews on the App Store are people who say they cried when they downloaded the app.”
Niche Audience as a Shoddy-Product Buffer — Acute Need Forgives Early Bugs
Cliff Weitzman shipped a buggy early version of Speechify that crashed frequently, but dyslexic users retried five times because there was no alternative for them. That acute, unmet need gave him time to improve the product without losing his early cohort. The lesson: the more specific the pain you solve, the more patience your users extend — a forgiving wedge that broad-market apps can't replicate.
“The next centric circle outside of dyslexia was ADHD and then low vision and autism and concussion and anxiety and second language learners. Today that's about 25% of our user base — 75% are neurotypical people: doctors, lawyers, accountants, people in the military, executives.”
Concentric-Circle Audience Expansion — Start Niche, Grow Outward in Rings
Speechify started with dyslexia, then expanded ring by ring to adjacent groups with similar needs — ADHD, low vision, second-language learners — before eventually reaching neurotypical professionals. Each new ring was already primed by word-of-mouth from the previous one. This planned concentric expansion let Cliff keep deep product focus while systematically broadening the addressable market without losing the origin story.
“I identified five Facebook groups for moms of kids with learning differences specifically dyslexia and then I did another five for ADHD I found the Reddit groups and I set a goal that I would post on all of them. I messaged six of my best friends and was like if I don't post in every single one of these groups by 10am Monday I have to run 10 miles.”
Reddit + Facebook Group Posting With Accountability — Early Niche Distribution Hack
Cliff's first distribution strategy was manual: identify the five most relevant Facebook groups and Reddit communities for his niche, then use social accountability with friends to ensure he actually posted. It worked well enough that Reddit flagged him as a bot and he had to create multiple accounts. The lesson is simple but often skipped — go where your specific users already congregate and post there systematically before spending on ads.
“We have been blessed to be alive in 2020 where consumer subscription is an acceptable business model. That was allowed for us because Spotify and Netflix educated the consumer that it's okay to pay a subscription for software. In my case they pay for software which is amazing because I don't have any COGS for the most part.”
Consumer Subscription Over Institutional Sales — Spotify Educated the Market for You
Cliff explicitly chose consumer subscription over selling to schools because he knew institutional sales to faith organizations would be slow, would require an enormous salesforce, and would lose him creative control. The shift in consumer psychology — Netflix and Spotify normalized paying recurring fees for software — made the timing right. For bootstrapped or early-stage apps, the absence of COGS in software subscriptions is what makes unit economics defensible.
“There's a very fun CAC to first payment period — we make sure the CAC is lower than the first payment period and then the renewals are gravy.”
CAC Must Be Lower Than First Payment — Renewals Are Pure Gravy
Cliff's unit-economics discipline is simple: if CAC is covered by the first payment, every subsequent renewal is profit. This framing forces creative and channel decisions to optimize for first payment conversion, not just installs or trial starts. It also means the team can scale spend confidently because they know the math works on day one — they don't have to bet on long-tail retention to justify acquisition costs.
“I got a Google Sheets list of the top 100 best-performing consumer subscription companies in the world and I emailed every CEO, every head of growth. Then I hopped on Zoom calls with them and I flew to wherever they were in the world. I literally sat behind them in their office and looked at how they bought Instagram ads.”
Cold-Outreach to Top-100 Subscription CEOs — Sit in Their Office Watching Instagram Ads
Cliff built Speechify's ad playbook not by hiring an agency but by personally shadowing the people already doing it at scale — founders of Reflectly, Blinkist, Dollar Shave Club, Grammarly, and Whoop. His tactic: cold email the top 100 subscription CEOs, get one call, show up in person. He learned at Reflectly that stories convert better than posts and polls drive more engagement than static images — insights that shaped years of Speechify ad strategy.
“The most important thing is volume. You put out 300 creatives — one out of 300 will blow up but you don't know which one. No one is a genius who can tell you. If they tell you that, that's just the algorithm — Instagram decides which one is gonna be really effective.”
Volume Wins Ad Creative — No One Can Predict Which 1 of 300 Will Blow Up
Cliff's core ad philosophy: produce as many creatives as possible, because predicting a winner is impossible. This is true for TikTok creators, YouTube influencers, and SEO writers as well — volume is the only reliable path to finding what works. Speechify produces 120 new creative pieces per week. At that cadence, the question shifts from 'will this work?' to 'how fast can we find the one that does?'
“We are just very frugal. I'm not gonna pay a margin of ads to an agency. We have a stable of really strong editors who do all the editing. I shoot with a teammate for two hours on a Sunday — that's the video for the week.”
In-House Creative as Competitive Moat — Frugality Beats Agency Margins
Speechify's four company values are product quality, speed, leading with love, and frugality — and frugality explains why they never outsource creative. Agencies add a margin layer without adding brand understanding. Keeping creative in-house means the people making ads are the same people who understand the product, the users, and the mission. This is the same reason they never outsourced engineering.
“We call this character Cruz Silver — a hyperbolized version of Cliff. He talks in a much deeper voice: 'Hi I'm Cliff founder of Speechify. What is Speechify? Well — you get stuff you need to read and we read it to you. Instantly.' Dead stare on the camera. Those convert really well because they're hilarious.”
Founder-as-Character Ad Persona — The Cruz Silver Playbook
Cliff accidentally discovered that a ridiculous founder-as-character persona converts better than polished product demos. Cruz Silver — Cliff in character with red headphones, deep voice, dead stare — became a meme that drove brand awareness far beyond its direct-response contribution. The key insight: leaning into absurdity builds memorability, and memorability compounds into lower CAC over time as the brand becomes the ad.
“I was like what are good ads — one of them is the Old Spice 'I'm on a horse' commercial. Who's got a horse? I posted to Instagram and turns out Logan Paul had a horse at his ranch. I went to the ranch, mounted his horse, and shot a Bold Spice commercial — and it crushed it on YouTube.”
Parody a Famous Ad Format — Old Spice on Logan Paul's Horse Crushed YouTube
Cliff's ad creative strategy includes duplicating proven formats from other industries: if a format works somewhere else, adapt it for Speechify. The Old Spice parody worked on YouTube because the cultural reference was already loaded with brand equity. Separately, Cliff identified a structural advantage: YouTube is owned by Google, which also runs the Chrome Store, so attribution from YouTube ads to Chrome extension downloads is unusually accurate — a channel arbitrage most apps miss.
“Every single person who comes on a call with me has already binge-watched the YouTube channel. It's as if it's our third call. When your time is very valuable and constrained, everything you do has to be serving — and this is about hiring.”
YouTube Channel as Recruiting Funnel — Candidates Arrive Pre-Sold at "3rd Call" Level
Cliff's personal YouTube channel wasn't built for marketing — it was built to document company-building philosophy and attract operators who already deeply believe in the mission. By the time a candidate gets on a first call with Cliff, they've watched hours of content and feel like they know him. This compresses the trust-building phase of hiring from months to a first conversation, a compounding advantage that gets more valuable as the company scales.
“What I'm doing now is finding people who have crushed it on TikTok making TikToks and hiring those people to help me come up with the content for new ads — because hey, I'm funny but I'm not the funniest person in the room. Let me find the funniest people.”
Hire TikTok Creators for Ad Content — Find the Funniest People, Not Ad Agencies
Rather than hiring a creative agency or a traditional CMO, Cliff recruits people who already have a proven track record of making viral short-form content on TikTok. The insight: the creative skill that works on TikTok — fast hooks, cultural fluency, comedic timing — is exactly the skill that works in paid social ads. Paying for a track record of organic virality is more efficient than paying an agency to guess what might work.
