As a girl growing up in Denmark and Sweden, Anine Bing dreamed of seeing the world. At 14, she convinced her parents to let her fly to Milan to pursue a career in modeling. “I was determined to go out in the world and make something for myself,” she says. Meanwhile, her future husband Nico was starting his first business at 17, running a clothing store that would grow to multiple locations across Denmark. “Whatever I could get my hands on, I tried to spin that around and make a little money and move on,” he recalls. Today, Anine and Nico are the powerhouse duo behind ANINE BING, a global fashion brand with more than 30 stores worldwide. They’ve built their success on complementary strengths — Anine’s creative vision and Nico’s business acumen — and a shared determination to create something bigger than themselves.

One of the most exciting shifts in AI right now is the rapid adoption of lifelike voice models across industries. These models have always held promise, but for years they struggled with speed, realism, and control. Existing solutions were too slow for real-time use, sounded unnatural, and lacked fine-grained control over elements like emotion or pronunciation, preventing enterprise adoption at scale. Cartesia's new Sonic-2 model is changing that. Built on the company’s pioneering state space models (SSMs), Sonic-2 pairs ultra-fast performance (40ms to first audio) with humanlike voices and total controllability. It’s already powering real-time, voice-native applications across gaming, healthcare, customer service, robotics, transportation, and more. Today, Cartesia announced their $64M Series A to accelerate the deployment of Sonic-2 and push the boundaries of what’s possible in generative voice AI. We’re proud to continue supporting Karan Goel and his team as they shape the future of how we communicate with technology. https://lnkd.in/eezquxX3

The best startups thrive in chaos. They move fast, break barriers, and rewrite the rules. Amid the uncertainty, they strip problems down to first principles, find innovative solutions, and set new records for growth. But as AI evolves from a feature to a fundamental building block, a new question arises: how much more efficiently can companies scale? New data shows a stark divide between the US and Europe when it comes to AI’s impact on hiring. In Europe, 84% of founders expect headcount to grow in the next 12 months, while in the US that number drops to just 54%. US founders are more cautious, prioritizing lean, highly efficient teams and bracing for AI-driven headcount shifts over the next five years. On March 10th at HumanX in Las Vegas, Index partner Martin Mignot will host a masterclass on Scaling Through Chaos in the Age of AI with Scale AI's Vijay Karunamurthy and Remote’s Marcelo Lebre. In this exclusive roundtable discussion, we’ll explore how AI is redefining startup growth, from hiring and GTM to sales training and customer support.

Congrats to Index-backed Taktile on raising $54m to enable AI Adoption for decision making in financial services. "AI’s rapid adoption in business has largely been concentrated in low-risk areas like content generation and customer support. However, its true potential lies in tackling high-stakes, business-critical decisions. Taktile exemplifies this shift — underway in many enterprises around the world — bringing AI to the forefront of risk decisioning in financial services, where accuracy is paramount, and errors carry significant consequences," writes Index Partner Carlos Gonzalez-Cadenas. Thank you Maik Taro Wehmeyer, Maximilian Eber and team for 4 years of partnership. Onwards!

The AI lip sync era is over: our team at Captions is excited to usher in a new era of audio-to-video foundation models. Captions was among the first to commercialize lip sync models, launching the original "lipdub" and "AI dubbing" in 2022. We trained our models and worked with companies like synclabs (pre-YC) as early as 2022. These models gained massive popularity and are used today by companies like Captions, Heygen and Synthesia for everything from dubbing to AI avatars. As the AI lip sync use cases have grown, a key weakness has emerged — half of visual communication happens through facial expressions and body language, not just lip movement. We've all seen it: AI lip sync videos saying one thing with their lips, but their expressions or body language saying another. This is the definition of bad acting. Enter Mirage by Captions, the world's first audio-to-video foundation model. Mirage uses audio alone as an input to generate realistic talking video at 720p resolution — all with "people" who don't exist. Optionally, you can prompt with text for changing location, clothes, accessories, and more. Today, we're releasing an early preview of Mirage to show that audio is enough to drive full-body animation, facial expression, eye movement, and more. To underscore an important point: We recognize this an incredibly useful foundation model, but one that can be dangerous if used incorrectly or maliciously. We are carefully crafting the surface areas where Mirage will be available to consumers in a safe way, and access will be limited as we release this technology. Mirage will be released within Captions suite of AI video editing and production tools over the coming weeks. Please apply below for access.
