Here’s how Jack Rolo describes his childhood: He was good at chess, and bad at spelling. He was good at math, and bad at reading. Rolo went on to study physics at Durham University in his native England—and despite often struggling in his courses, it wasn’t until after he graduated that he was diagnosed with dyslexia, a common language processing disorder that affects reading.

Rolo’s experiences informed his founding of Polygon, a Santa Monica-based diagnostics startup that emerged from stealth on Friday with $4.2 million in funding, and the goal of better diagnosing dyslexia, ADHD and other learning-related disabilities. The funding includes a $3.6 million seed round led by Spark Capital, as well as $600,000 in pre-seed funding led by Pear VC.


“It really is a product I wish I'd had access to at an earlier age myself,” Rolo told dot.LA.

After moving to California to earn his MBA degree at UC Berkeley, Rolo met his co-founder Meryll Dindin, who now serves as Polygon’s chief technology officer. Together, they’ve built a platform that aims to partner with schools to test children for a myriad of disabilities that may affect academic performance. (The startup claims it’s already teamed with schools in California, but did not disclose which.) Rolo says he envisions that these assessments become as ubiquitous as vision and hearing exams: that every student, regardless of age, background or academic performance, will be tested.

As is, testing for disorders like ADHD and dyslexia often depends on parents, teachers or pediatricians observing a child, detecting something amiss and intervening. There are problems with this method; for instance, girls are chronically underdiagnosed with ADHD because it presents itself differently than it does for boys. Teachers juggling crowded classrooms may not be able to perceive why a specific child is falling behind. And Black and Latino children are often overlooked when it comes to diagnosing disabilities.

“Common roots of referral are teachers, and typically that's flagged because they'll see the student failing,” Rolo said. “That's part of the problem—that this then becomes almost a wait-to-fail approach, when ideally you want to pick these things up proactively.”

Polygon employs full-time psychologists who evaluate students through a telehealth platform. After undergoing a range of standardized assessments and interviewing their parents and teachers, a student who is diagnosed will receive an "Individualized Education Program," a schooling curriculum tailored toward their disabilities.

Assessments start at $995, which Polygon says is up to five times cheaper than traditional disability testing alternatives. The company plans on driving that cost down further by collecting a large data sample of assessments and building machine learning technology to “pre-screen” students; those who are flagged would then undergo more extensive testing.

“Ultimately, what we're trying to move toward is a model quite similar to the optician, where everyone gets the evaluation,” Rolo said. “Yes, assessments are still not accessible for all families just yet—but this is the beginning, and we hope to drive this cost down way further over time.”

Polygon said the new funding will go toward expanding beyond California and growing its network nationally.

How Replify Found Its Niche and an Acquirer

🔦 Spotlight

Hello LA,

This week’s startup story began three years ago with an AI assistant built for almost any small business. It ended, or perhaps graduated, with an acquisition by one of the fitness industry’s largest technology providers.

ABC Fitness has acquired Replify, an AI platform that manages customer communication for gyms and wellness businesses across phone, text, email and chat. Its virtual agents can answer questions, qualify leads, schedule tours and classes, follow up on missed calls and run outbound campaigns. Financial terms were not disclosed.

Before Replify found its footing in fitness, it was HeyLibby, a general-purpose AI assistant founded in 2023 by former Zillow colleagues Spencer Rascoff, Tony Small and Anna Rodriguez. The company was incubated inside Rascoff’s 75 & Sunny Labs and initially set out to help small businesses turn incoming messages into qualified leads.

That broad vision gave HeyLibby a large potential customer base, from real estate agents and contractors to hairstylists and event planners. But as the team searched for product-market fit, one industry’s problem stood out. Gym and wellness employees were often too busy helping customers in person to answer every call, text or email, leaving prospective members waiting and potential revenue on the table.

That insight reshaped the company. HeyLibby narrowed its focus to fitness and wellness, raised a $4.5M seed round in 2025 and later rebranded as Replify. It went on to work with brands including Gold’s Gym and UFC Gym, proving that its AI agents could do more than answer routine questions. According to the company, customers have captured up to 10 times more leads and shortened sales cycles from roughly 30 days to as little as three to five days.

ABC Fitness became a natural next step. The company provides software to more than 30,000 fitness businesses serving over 40 million members worldwide. By adding Replify to its platform, ABC can offer gyms an always-available AI front desk while bringing Replify’s technology to a much larger global customer base.

Replify’s journey offers a useful lesson amid the rush to build AI products for everyone. The company began with a broad promise, identified a customer with a specific and expensive problem, and built deeply around that need. Gym owners did not need another flashy chatbot. They needed someone to answer the phone when the front desk could not.

Sometimes the smartest AI strategy is simply picking up the call.

      From Uber to Atoms: Travis Kalanick’s $1.7 Billion Return

      🔦 Spotlight

      Hello LA,

      Nine years after his turbulent exit from Uber, Travis Kalanick is back with a new company, an enormous war chest and, apparently, some unfinished business.

      Los Angeles-based Atoms announced this week that it has secured a $1.7 billion equity investment led by Andreessen Horowitz, with a16z cofounder Ben Horowitz joining its board. Bain Capital, Fifth Wall, Uber and several other investors participated, while a roster of major banks, including Goldman Sachs, JPMorgan and Bank of America, are listed as debt partners.

      Yes, Uber itself is now backing the comeback of its famously ousted cofounder. Silicon Valley may preach disruption, but it has always appreciated a good redemption arc.

      Atoms is the culmination of the company Kalanick has spent the past eight years building largely out of public view. Formerly known as City Storage Systems, the parent company behind CloudKitchens, it is now bringing its businesses together under one ambitious umbrella: Atoms Food, Atoms Mining and Atoms Transport.

      The premise is that AI’s next major frontier will not be confined to screens, chatbots or software. Atoms wants to build what Kalanick calls a “computer for the physical world,” using software, sensors, robotics and AI to automate how physical goods are produced, stored and moved.

      That means tackling decidedly unglamorous but enormous industries such as mining, construction, food production and heavy transportation. Rather than betting on humanoid robots that can theoretically do everything, Atoms is focused on specialized machines designed to perform specific, economically useful jobs.

      In other words, the robot does not need a face. It needs a business model.

      For a16z, the investment is as much a bet on Kalanick as it is on industrial AI. In an essay bluntly titled “Travis Is Back,” Horowitz argues that Kalanick possesses the rare mix of technical range, endurance and sheer force of will required to drag old-line industries into a new technological era. The firm’s broader thesis is that robotics will eventually handle much of the repetitive work involved in making, moving and storing physical goods, creating a market potentially as consequential as computing itself.

      There is also some history being settled. Kalanick, Horowitz and Marc Andreessen nearly partnered during Uber’s early days but never completed the deal. In a new conversation about Atoms, Kalanick and Horowitz revisit that missed opportunity and the long road that brought them back together. Sixteen years later, the check is considerably larger.

      The scale of the investment is remarkable, but so is its location. Atoms is headquartered in Los Angeles, giving the city a front-row seat to one of tech’s boldest industrial AI bets. It also reinforces something increasingly evident across LA’s startup ecosystem: the next era of AI will not only be written in code. It will be built in kitchens, warehouses, mines, vehicles and factories.

      Whether Atoms becomes the operating system for the physical world or simply proves that even $1.7 billion cannot make atoms behave like bits remains to be seen. But Kalanick is taking another enormous swing, and this time, Los Angeles is where the comeback story begins.

          LA’s New Defense Startup Comes Out Swinging

          🔦 Spotlight

          Happy Friday LA,

          A new defense startup just emerged from stealth with one of the week’s biggest funding rounds and a mission built for the realities of modern warfare.

          Los Angeles-based Singularity raised an oversubscribed $80M Series A at a $400M valuation to develop low-cost air defense systems at scale. Khosla Ventures and Felicis led the round, with participation from AE Ventures, NEA, Long Journey, Harpoon, Menlo Ventures, Y Combinator and others.

          The company is targeting an increasingly lopsided problem: inexpensive drones and munitions can be produced quickly and deployed in large numbers, while the systems used to intercept them are often costly and difficult to manufacture at comparable scale.

          Singularity’s answer is to borrow from the automotive industry. Its manufacturing team, which includes talent from Tesla and Toyota, is building an assembly line designed to rapidly produce interceptors, while developing the hardware and software in-house. The broader team also includes veterans of SpaceX, Anduril and Lockheed Martin, along with military operators who have deployed air defense systems in combat.

          The company is already conducting multiple flight tests each month. Now it has $80M to prove that air defense can be manufactured more like cars and less like traditional military hardware.

          Whatnot Wants AI to Find Your Next Obsession

          The thrill of Whatnot is not always finding what you came for. It is stumbling into a live show and discovering something you suddenly need to own.

          Now the Marina del Rey-based marketplace is investing in AI to make those moments happen more often.

          Whatnot acquired Shaped, a machine-learning startup that builds real-time recommendation and search systems. Financial terms were not disclosed.

          Shaped founder and CEO Tullie Murrell and nearly a dozen engineers and researchers will join Whatnot, where Murrell will create and lead a new applied AI research group focused initially on discovery and personalization.

          The acquisition comes as Whatnot’s marketplace becomes much larger and more complicated. The company launched more than 35 new categories last year and over 45 during the first half of 2026. Cross-category purchasing is also up 170% year over year, suggesting users are increasingly willing to venture beyond the products that first brought them to the platform.

          Unlike a traditional online store, Whatnot’s inventory shifts constantly as sellers start and end live shows. That makes recommending the right product or stream in real time a particularly difficult AI problem.

          Whatnot is betting Shaped can help solve it. Because the longer shoppers keep discovering new interests, sellers and communities, the less likely they are to close the app.
