Can you remember all the details of the business meetings you had last week? Or what you said to your kids when you got home from work? Our ability to remember changes with age. The memories might be there, but they are not quite so accessible. And with a hectic pace of life, human memory can only retain so much. But with the evolution of AI, all that could soon become a thing of the past.
Serial entrepreneur Dan Siroker believes he has found a solution to augmenting human memory in Limitless, an AI pendant that captures and preserves every the minutiae of everyday life, from the detail of work meetings to the informal interactions with family and friends that are otherwise lost in the mists of time.
The inspiration for the human augmentation tool came from an experience Siroker had in his twenties when he started to lose his hearing due to a condition called otosclerosis. He says: 'When I tried a hearing aid, it was magical. To lose a sense and then regain it was like gaining a superpower, and ever since then, I have been on a hunt for ways that technology can augment human capabilities and give us superpowers.'
Political inspiration
Siroker started his career as a product manager at Google before leaving in 2007 to join the Obama campaign. 'It was a talk that Obama gave at Google about his desire to take what we were doing there around science and data and bring it to the government that inspired me,' he says. 'It was one of the first campaigns that used a lot of AB testing on the website and experimented with how best to persuade the world that Barack Obama was a good candidate. He won.'
That inspired Siroker to launch his first company, Optimizely, a website AB testing company that effectively turned that political campaign work into a product. It was around this time that his hearing issues began, prompting him to sell his business for $300 million and start work on what would ultimately become Limitless.
Perfect memory
Two early iterations included Scribe, which transcribed Zoom meetings, and Rewind AI, which could capture and comprehend everything you do on your computer. 'We then started to think about real-world conversation, not just Zoom meetings, but in-person conversations, dinnertime conversations; the concept of perfect memory,' says Siroker. 'That's what led to the Limitless pendant, which captures and preserves everything you say and hear and makes it so valuable.'
Developing the hardware element of Limitless was a huge challenge that Siroker admits he seriously underestimated. Several investors tried to talk him out of it. He says: 'With Optimizely, I didn't have to worry about physical matter or coordinating with Chinese factories. I even found the type of people who make hardware very different from those who make software.'
Limitless, which Siroker cofounded with Brett Bejcek, has applications for business, productivity, etc., and beyond work, for family life. 'It helps me be a better dad,' he says 'Every morning, I get a push notification from the app that looks at everything I've said, everything I've heard, how I've interacted with my kids, and gives me concrete examples of things I could have done better or differently. That kind of life coach capability is only possible when you have something that captures what's going on throughout your day.'
For neurodivergent people, for example, those with ADHD, who have focus and memory issues, Limitless is a tool that can keep them on track and augment their other natural talents.
Secure by design
One of the biggest concerns around AI and its use in so many application is privacy, but as Siroker explains, Limitless is secure by design. He says: 'We use Apple's accessory kit for authentication encryption, so the data is never stolen. Even if you lose your pendant, a third party cannot access the data. It's HIPAA compliant, and in the U.S., provides the same level of protection as your health records.'
Since its inception in October 2023, Limitless is now available in every country where regulations permit, with over 10,000 people already wearing it, and a much longer list of people who have ordered it. Limitless has a remote-first team of 18 based throughout the U.S. and is on track to achieve a million sales in the next two years.
Investors and users
The company has raised $33 million from high profile investors that include Sam Altman, First Round Capital, and more recently NEA. Charles Hudson, managing partner and founder of early-stage venture capital firm Precursor Ventures is both an investor and an avid user of Limitless.
When Siroker initially approached him with the concept of perfect memory, Hudson was intrigued but admits that he didn't immediately grasp it. Then with arrival of Rewind, the vision became clearer.
Hudson says: 'Having a meeting assistant that could deliver high-quality notes for my weekly 70 to 80 meetings would be useful in helping me manage the cognitive load of keeping track of what was said, by whom, and what things I had committed to do. When I invested in Limitless, while there were other meeting assistant tools in the market, I didn't feel any of them had this vision of perfect memory across so many aspects of personal and professional life.
'While Dan talks about it as a perfect memory, I think about it as a perfect presence; with the pendant on, I don't have to worry about taking notes or writing things down because the pendant will catch it all.'
Digital diary
Entrepreneur Josh Lehman is founder of Martian Engineering, which uses AI to speed up software development. He is also a father of two young children. He originally bought the Limitless pendant thinking it would help with work, but quickly realized its biggest impact was at home, especially with his kids.
He says: 'The first day I wore it was over the Easter weekend. I wasn't working and spent the day doing things with the children, going to the playground, coloring, and handling tantrums. The next day, I got a notification from Limitless summarizing my day, including moments where I could've been more patient.
'That's when it clicked. The pendant was capturing all the small, meaningful moments that are easy to forget; moments that photos alone can't preserve. It was like a digital diary. It's now part of my daily routine, especially valuable during mornings and evenings with my kids.'
Transforming human memory
As for the future of human augmentation, Siroker envisages LLMs getting smarter and eventually developing consciousness and a subjective experience. It will transform our reliance on human memory. He says: 'I'm convinced that our grandkids will look back at how we lived our lives today and be shocked at how we went through our lives forgetting 90% of what happened after a week.'
