He couldn't read a page as a kid. So he built the app that reads everything aloud - now in the ears of 56 million people.
Cliff Weitzman runs a company whose entire job is to read out loud. The irony writes itself: he spent his childhood unable to get through a single page. Today Speechify, the text-to-speech app he founded and leads as CEO, turns books, PDFs, emails and web pages into natural-sounding speech for more than 56 million people, in over 200 languages, using a library of 1,000-plus AI voices. The company has grown past 200 engineers. In June 2025 it walked away from Apple's WWDC with a Design Award - the kind of trophy that usually goes to studios, not to a tool born out of one student's coursework.
Start with what he's doing now, because it explains everything that came before. Speechify's pitch is deceptively plain: point it at any text and it talks back. Underneath sits AI, deep learning, optical character recognition that scans a printed page and reads it, and voice models good enough that you forget a machine is speaking. The product is used by speed-readers and commuters, but its center of gravity is people who, like its founder, find the printed word expensive. For them the app isn't a convenience. It's an unlock.
"I'm not broken. I'm not stupid. I'm not lazy. I just learn differently."
- Cliff Weitzman, on his dyslexia diagnosisWeitzman was born in Ra'anana, Israel, and moved to the United States at thirteen. He was diagnosed with dyslexia in the third grade, and he tells the story not as a tragedy but as a relief. He has called it the best day of his life - the day a word finally explained the struggle. For years before that, he would sit in elementary school with a book open in front of him, pretending to read. Reading a single sentence, he says, takes about as much energy as doing four-digit multiplication in your head.
Here is the detail that tells you who he is. Before the family moved to America, his father found an English-language audiobook of Harry Potter. Cliff didn't speak English yet. He couldn't follow the plot. But he recognized the anchors - Harry, Hermione, Hogwarts, Hagrid, Alohomora - and used them to navigate. He played the book twenty-two times in a row, until he had the first chapter memorized. That was the method: not reading the words, but absorbing them through the ear until the language stuck. The man who later built a listening machine first taught himself a language by listening on repeat.
The Brown chapter follows the same logic. He got into Brown University on an essay he now calls terrible - half apology for being dyslexic, half frantic attempt to prove he was smart anyway. Once there, the reading load was brutal. So he rigged his computer to read his coursework aloud, and found he could move through material roughly three times faster that way. Classmates noticed. They asked for copies of his setup. The requests kept coming, and the requests became a product. He graduated in 2016 with a degree in Renewable Energy Engineering - a stitch of computer science, engineering and physics, with industrial design courses at RISD on the side - and a head start on what Speechify would become.
"Your mission is to be who you needed most when you were growing up. At least, it's mine."
- Cliff WeitzmanSpeechify wasn't the opening act. Weitzman is a serial founder who shipped a string of projects in and around college - BoardBrake, CellArmor, a launcher called StarterPack that pulled in over 70,000 downloads, and Find Me Scholarships among them. He served as a Google Student Ambassador and took first place at startup pitch competitions at MIT and Stanford. The pattern is consistent: spot a friction, build the smallest thing that removes it, ship it, watch who shows up. Speechify is simply the one where the friction was his own, and the people who showed up numbered in the tens of millions.
The recognition has stacked up. Forbes named him to its 30 Under 30 list in the Education category. Inc. put Speechify on its list of America's Top 30 Emerging Companies. New York Jewish Week included him in its 36 Under 36. Google flagged the app as a favorite Chrome extension. None of it changed the original brief. Ask him what the company is for and the answer points back to the kid faking his way through a reading group: build the tool that kid needed, and hand it to everyone who is still that kid.
There's a tidy symmetry to a person who reads roughly a hundred audiobooks a year and almost never reads with his eyes, running the company that made that possible at scale. Weitzman doesn't treat his dyslexia as a footnote to the success story. He treats it as the spec sheet. The difficulty was the design brief, the workaround became the product, and the product became a way for millions of other people to stop apologizing for learning differently.
Taught himself English by replaying one Harry Potter audiobook 22 times until he'd memorized the first chapter.
Reads roughly 100 audiobooks a year - and rarely reads a single one with his eyes.
Studied Renewable Energy Engineering, not computer science, then went and built an AI voice company.
Has four siblings, including entrepreneur brother Tyler. Founding runs in the family.
Won first-place at startup pitch competitions at both MIT and Stanford before Speechify took off.
Before Speechify came BoardBrake, CellArmor, Find Me Scholarships and a launcher with 70,000+ downloads.
