The Future of Software Interfaces Is Generative — Thesys Kicks It Off in San Francisco

Last night, I walked into a room in San Francisco filled with founders, designers, and product folks — and walked out with a front-row glimpse of what the future of software might feel like.

As someone who hosts eChai meetups here in SF, I’ve been to my fair share of GenAI gatherings. But this one hit different. It was the launch of Thesys, in collaboration with The GenAI Collective, and the focus wasn’t just on agents or LLMs — it was on a bold new idea: Generative UI.

The Startup: Thesys

Thesys is what happens when two brilliant minds — Rabi Shanker Guha and Parikshit Deshmukh — decide that the way we design software hasn’t kept up with the way we build intelligence.

Instead of creating screens in Figma and handing off to engineers, they’re building a system where AI generates the UI itself. Their platform, C1, lets developers feed in context, and the frontend adapts — forms, charts, tables, inputs, cards — all rendered dynamically by AI.

They call it Generative UI. And they’re not wrong — it’s not just faster than design. It skips the whole traditional workflow.

They've raised $4M from Together Fund and 8VC, and what they’re building feels like the frontend equivalent of what Stripe did for payments.

The event — hosted by Thesys and the GenAI Collective — had all the right energy. Real conversations. Sharp minds. People not just networking but building mental models together.

Rabi and Parikshit kicked it off with a keynote and live demo of their engine. The UI actually responded to an AI agent’s intent in real-time. It was wild.

Then came the fireside chat:

This didn’t feel like a product launch. It felt like a new chapter.

Why This Matters

If you’re a founder building AI-first apps, you need this on your radar.

Because just like LLMs changed how we write code, Generative UI will change how we build products.

Thesys is betting big on this shift. And judging by the buzz in that room — they’re not alone.

Final Takeaway

San Francisco isn’t just about models anymore. It’s about interfaces that think.

And this week, Thesys made that future feel real.
