Who is Karan Goel? DPS RK Puram and IIT Delhi graduate who raised $100 million for his Silicon Valley startup
Karan Goel, a DPS RK Puram and IIT Delhi alumnus, is gaining attention online after his startup Cartesia raised $100 million from top-tier investors.
Karan Goel, an IIT Delhi alumnus and Stanford-trained AI researcher, is creating buzz online after his US-based startup Cartesia announced a major funding round and a breakthrough in real-time voice technology.
Taking to X, Goel announced that Cartesia has raised $100 million from top-tier investors including Kleiner Perkins, Index Ventures, Lightspeed and NVIDIA. He also announced the launch of its new voice model, Sonic-3, which claims to be one of the fastest voice AI models currently available.
Goel explained that Sonic-3 delivers breakthrough naturalness with emotional range, supports 42 languages, and achieves 190ms end-to-end latency, which is significantly faster than most transformer-based systems used by competitors. The company relies on State Space Models (SSMs) instead of transformers, enabling more human-like, low-latency speech generation suited for live conversations.
“If you're qualified and we can't make your voice AI better than what you're using now, I'll donate $5K to your chosen charity,” Goel tweeted.
The post quickly went viral, drawing praise from founders, engineers and AI enthusiasts.
Michelle Lim, co-founder of Flint, wrote, “From this day on there are two eras. The world before Sonic 3. And the world after Sonic 3. Congrats on the launch!!”
Another user commented, “The way sonic picked up the sentence in Hindi, laughed and then continued the conversation, is really impressive. I gotta try building something using sonic 3 now.”
A third user added, “190ms end-to-end is seriously impressive. The breakthrough on emotional range is what really caught our attention, that’s been the missing piece for natural conversation.”
