Head of Engineering & AI Research (Co-founder)

Co-Founder & CTO — 169Pi (Mumbai / Hybrid / Remote Possible)

About 169Pi

169Pi is an AI research and infrastructure company building India’s next generation of reasoning-first models, APIs, and agentic platforms.

We’ve already done what most deep-tech startups only talk about, we trained and deployed our own large model and shipped real products used by developers and institutions.

Our flagship model, Alpie Core, is a 32B-parameter reasoning model (4-bit optimized) that outperforms GPT-4o, Claude Sonnet 3.5, and DeepSeek R1 on reasoning and coding benchmarks.

It powers a fast-growing ecosystem :

• Alpie Core — our flagship reasoning model, the foundation of all 169Pi products.
• 169Pi Playground — developer sandbox to test models, tune parameters, and experiment with reasoning tasks.
• 169Pi API Platform — the unified interface to access the Playground and purchase Alpie Core APIs for enterprise and developer use.
• Alpie Chat Assistant — launching this week, a reasoning-centric chatbot with deeper capabilities, real-time context, and domain-specific tools.
• Vibe Code / Alpie Code — our intelligent coding platform (Planner → Coder → Executor → Debugger → Memory Layer) that lets users build full products or websites end-to-end.

Our technology is already deployed with ISRO and the Bihar Government, with multiple pilots in progress. We’re signing up new users daily on both the Playground and API Platform.

169Pi is a deep-tech company rooted in R&D, reasoning research, and real-world deployment.

We’re now expanding our core engineering leadership as we raise a USD 7–10 M seed round to scale compute, research, and global reach.
