You ruined demos for me! Any other demo is gonna feel meh after this one.
Real life, baby

What did I just watch? Really thought this was AI generated. What a time to be alive! Also whoever created the post countdown video - well done!

India ranks 100 for broadband data speeds. Those opposing @Starlink and chest thumping about data affordability in India should look at the reality of “high speed data”in India. Affordability should not come with sub-standard service. Source: ooklaserver.org/global-index

After frequently taking waymos /robotaxis, riding an uber feels less safe.

Is it just the market though especially when it comes to voice models? It begs the question - why is eleven labs still the preferred tts model even for Indian languages? Despite being a “sovereign” model why isn’t sarvam the leader. I think it’s also about focus. In India we try to make everything without focusing on one product, making it world class.

On SigmaMind it runs out of the box. You skip the plumbing and go straight to building the agent. Live today. Experience it now on @sigmamind_ai

Why Coda: trained on real full-duplex conversations between actual people, not audiobook narrators. Sub-200ms latency. Pronunciation you fix in minutes, not a retrain.

Rime's new flagship TTS model, Coda, is now live on SigmaMind AI. @rimelabs @sigmamind_ai Here's why we added Coda to SigmaMind.. 🧵

Excited to announce Slashy The first email client that works for you. The real cost of email isn't the time. It's the mental load of constantly checking it, just in case something needs you. Slashy kills that. You never need to open your inbox unless Slashy tells you. Try it out at slashy.com

As an early user I can say - best thing I like is @slashyai naturally understands my style and a draft is ready to send as a soon as I open an unread email. Sending emails is so much faster.

#53: #AIRadarDaily — @sigmamind_ai There is a massive illusion in the AI space right now when it comes to voice. The demos look like magic. But the moment you try to deploy a voice agent in a real-world enterprise setting, reality hits. You end up duct-taping together different transcription APIs, LLMs, and text-to-speech models. The result? Unbearable latency, awkward robotic pauses, and systems that fail completely the second a customer with a thick accent tries to interrupt. Building truly conversational voice AI isn't just a model problem; it is a deeply complex, unglamorous systems problem. SigmaMind AI is quietly building the definitive orchestration layer to solve exactly this. Founded by Ashish Agarwal and Pratik Mundra, SigmaMind is an enterprise-grade platform that lets companies deploy production-ready voice and chat agents that don't just listen, but actually reason, trigger APIs, and complete tasks in real time. The true moat here is sheer, unadulterated speed and infrastructural rigor. The team have engineered a system that maintains sub-one-second voice-to-voice latency, even when absorbing the brutal drag of traditional telephony overhead. By processing streaming transcripts and acting before a sentence is even finished, their agents can handle interruptions flawlessly and trigger workflows mid-utterance. They handle the incredibly messy audio plumbing so businesses can focus purely on logic and behavior. The market? Customer support teams, call centers, and global e-commerce brands who are already routing over a million calls a month through the platform. They realize that in the world of voice AI, a one-second delay is the difference between a resolved ticket and a lost customer. What stands out here is the audacity of the build. It takes immense technical courage to look at a highly fragmented ecosystem and decide to build the robust, connective tissue from the ground up. This is an Indian team building the complex cognitive infrastructure for global conversational AI. This is the kind of rigorous, head-down execution that gives momentum to the Product Nation dream. Let's celebrate the builders. w/ Jay Ingle & Dikshant Joshi #VoiceAI #ProductNation

We just made voice agents self-improving. Here's how it works 👇 Define your test cases. Run simulated calls. Get structured results back. Feed them into your prompt -- automatically, using Claude, Cursor, or Codex through the SigmaMind API or MCP. Your voice agents just keep getting better.

Would love to!

We launched the SigmaMind MCP server on Product Hunt today. 5M+ calls processed. 2,500+ voice agents in production. And now you can build and manage all of it from inside Claude -- no dashboard, no boilerplate. Upvote/comment if you want to support 👇 producthunt.com/products/sig…
