Who makes Nexus · Kushal SM

Kushal SM

IIT Bombay, B.Tech in Aerospace Engineering, 2020–2024.
Emergent, engineer, July 2025 to March 2026. Emergent is the AI app builder backed by SoftBank, Khosla Ventures and Y Combinator that reached $100M in annual run-rate revenue eight months after launch. Kushal was on the engineering team through that growth: he built the mobile deployment pipeline, brought Codex onto the platform, and built Emergent's customer-support and analytics agents and its internal MCP servers.
Before that, applied AI at Elzo.ai and research on graph neural networks.

Now he builds products for the new app platforms inside ChatGPT and Claude. Nexus is the main one.

Nexus went through both app-store-style reviews:

Claude: approved and listed in the Claude connectors directory since July 2026.
ChatGPT: approved and listed in the ChatGPT plugin directory since September 2026.

Both reviews check what the app does with your data, how it signs you in, and how its tools behave, before it's listed.

Nexus stores only what it needs: your account, the meals, workouts and weights you log, and friend connections you choose.
It never sells, rents or trades your data, and never uses your logs for advertising or to train AI models.
Data is stored on Cloudflare, over HTTPS, with OAuth sign-in.
Ask for deletion at any time; it's done within 30 days.
You can read your whole history from any chat, or from the command-line tool.

Coffeetable: a book-reading app inside ChatGPT and Claude, also listed in both directories.
Chrome Relay: a tool that lets coding agents work in your real Chrome browser.
