## Lessons from Cliff Weitzman

Cliff Weitzman originally built Speechify as a personal workaround to read his coursework at Brown University after a dyslexia diagnosis. He scaled the text-to-speech app to millions of users through a "Volume of Work" philosophy that treats relentless experimentation as the fastest way to learn. This profile gathers his approaches to productivity, engineering culture, and rapid learning.

### Part 1: Navigating Dyslexia and ADHD

1. **On the struggle of reading:** "I am dyslexic. Reading a sentence takes me the same amount of energy and brainpower as most people take when solving a four-digit long division math equation in their head." — [*Source: GoLocalProv*](https://www.golocalprov.com/?ref=antoinebuteau.com)
2. **On his diagnosis:** "I was diagnosed in 3rd grade. It was the best day of my life. Before that, I would pretend to read in elementary school." — [*Source: Speechify Blog*](https://speechify.com/?ref=antoinebuteau.com)
3. **On the feeling of being misunderstood:** "I'd sit with the book open in front of me and pass my finger under the words so that people wouldn't think I was dumb, or lazy." — [*Source: LagosMums*](https://www.lagosmums.com/?ref=antoinebuteau.com)
4. **On his life mission:** Weitzman frames Speechify as a personal mission: build the support he needed when reading, school, and self-belief were hardest. — [*Reference: Medium essay on his dyslexia mission*](https://medium.com/@cliffweitzman/dyslexia-book-day-1-introduction-2ae5543e89a?ref=antoinebuteau.com)
5. **On overcoming academic barriers:** He recognized early on that dyslexia was a barrier in traditional settings but leveraged audiobooks like Harry Potter to maintain his curiosity. — [*Source: Cliff's Substack*](https://substack.com/?ref=antoinebuteau.com)
6. **On designing for neurodivergence:** Speechify was built to bridge the gap for those who struggle with traditional reading, turning a personal deficit into a technological advantage. — [*Source: Made For Us Podcast*](https://captivate.fm/?ref=antoinebuteau.com)
7. **On the emotional weight of learning differences:** Weitzman treats dyslexia as both a learning challenge and an identity challenge; the work is helping people feel capable while they find the right tools. — [*Reference: Dyslexia Journey episode notes*](https://dyslexiajourney.buzzsprout.com/2077817/episodes/14386818-learn-to-love-listening-ft-cliff-weitzman-dyslexic-founder-and-ceo-of-speechify?ref=antoinebuteau.com)
8. **On ADHD and productivity:** Weitzman’s productivity system starts from fit: audio, speed control, and text-to-speech let people work with their attention patterns instead of fighting them. — [*Reference: Speechify recap of CNBC Fortt Knox interview*](https://speechify.com/news/cnbc-jon-fortt-interviews-founder-and-ceo-of-speechify-cliff-weitzman/?ref=antoinebuteau.com)
9. **On early accommodations:** Before Speechify, he hacked his own education by manually recording readings and using early text-to-speech tools to survive his coursework at Brown. — [*Source: Brown University News*](https://www.brown.edu/?ref=antoinebuteau.com)

### Part 2: The Volume of Work Philosophy

1. **On the core formula:** The ultimate strategy in uncertain domains is "Volume × Leverage = Output." — [*Source: Speechify Blog*](https://speechify.com/?ref=antoinebuteau.com)
2. **On winning through experimentation:** The individual or organization that runs the most experiments is mathematically favored to win. — [*Source: Speechify Blog*](https://speechify.com/?ref=antoinebuteau.com)
3. **On ad testing:** Speechify turns marketing into a high-volume learning system, generating roughly 1,300 AI ads per day and letting performance data decide which messages earn spend. — [*Reference: BigGo summary of 20VC interview*](https://finance.biggo.com/news/82a0b4613f50dfa4?ref=antoinebuteau.com)
4. **On volume as a choice:** "Volume" is not a personality trait; it is a conscious, deliberate strategy chosen to accelerate learning. — [*Source: Speechify Blog*](https://speechify.com/?ref=antoinebuteau.com)
5. **On college applications:** As a high school student, he applied the volume principle by applying to 26 colleges instead of the standard six. — [*Source: Speechify Blog*](https://speechify.com/?ref=antoinebuteau.com)
6. **On relentless editing:** Weitzman’s volume philosophy predates Speechify: he applied the same repetition-and-improvement loop to college applications, including 48 drafts of one essay. — [*Reference: BigGo summary of volume philosophy*](https://finance.biggo.com/news/82a0b4613f50dfa4?ref=antoinebuteau.com)

8. **On removing the fear of failure:** Running a massive volume of tests naturally dilutes the sting of any single failure, turning it into mere data. — [*Source: BeFreed AI*](https://befreed.ai/?ref=antoinebuteau.com)
9. **On adversity quotient:** Weitzman hires for the ability to stay with a hard problem after the easy effort is gone; AQ matters because the company-moving work sits on the far side of sustained difficulty. — [*Reference: BigGo summary of AQ hiring framework*](https://finance.biggo.com/news/82a0b4613f50dfa4?ref=antoinebuteau.com)
10. **On execution speed:** Weitzman sees speed as a compound advantage: as tools commoditize more work, the edge shifts to how quickly teams learn, decide, and ship. — [*Reference: BigGo summary of speed as advantage*](https://finance.biggo.com/news/82a0b4613f50dfa4?ref=antoinebuteau.com)

### Part 3: Radical Learning and Information Consumption

8. **On the multidisciplinary mindset:** At Brown University, he built his own major, combining computer science, engineering, and physics to synthesize distinct fields. — [*Source: Wikipedia*](https://en.wikipedia.org/wiki/Cliff%5FWeitzman?ref=antoinebuteau.com)
9. **On reading a book a day:** He leverages text-to-speech technology to consume long-form PDFs and books in a single day, breaking the traditional speed limit of reading. — [*Source: Cliff's Medium*](https://medium.com/?ref=antoinebuteau.com)

7. **On QA as a primary skill:** In Weitzman’s AI-heavy engineering culture, shipping faster raises the value of verification: candidates and teams have to prove they can use AI without losing correctness. — [*Reference: BigGo summary of AI-assisted engineering culture*](https://finance.biggo.com/news/82a0b4613f50dfa4?ref=antoinebuteau.com)
8. **On repositioning struggling engineers:** If an engineer falters in core development, he tests them in a QA function to see if their true strength lies in verification before letting them go. — [*Source: AudioScrape*](https://audioscrape.com/?ref=antoinebuteau.com)
9. **On AI-assisted engineering:** Weitzman pushes engineering toward active AI use: reading large codebases, shipping under time pressure, and making coding agents part of the normal workflow. — [*Reference: BigGo summary of Claude Code adoption*](https://finance.biggo.com/news/82a0b4613f50dfa4?ref=antoinebuteau.com)

8. **On the evolution of software:** We are moving from software that simply stores information to AI that actively synthesizes and spoon-feeds it to us optimally. — [*Source: Speechify Blog*](https://speechify.com/?ref=antoinebuteau.com)
9. **On embracing the new toolset:** Weitzman treats AI tools as a required part of modern engineering leverage; resistance has to be explained, not quietly accepted. — [*Reference: BigGo summary of AI adoption expectations*](https://finance.biggo.com/news/82a0b4613f50dfa4?ref=antoinebuteau.com)

### Part 7: Building Speechify
