Collaborative AI app builder for teams

Deep Interactions is a humans-in-the-loop AI builder. We don't leave you with a spaghetti mess of a code. We bring product intelligence and power the context layer that enables your team to build in sync - saving companies tokens, time, and nerves. You give us a problem and we ship a working AI product in the same afternoon.

Deep Interactions — Collaborative AI Builder for Teams
See original launch post

Hello! I'm Sruthi Viswanathan, founder of Deep Interactions.

TL;DR

Deep Interactions is a collaborative AI builder for teams. We turn messy ideas, data, and tools into working AI products in a single afternoon — so companies stop burning months and millions on pilots that never ship.

Ask: Intros to CEOs, CTOs, COOs, CFOs, or Heads of AI with an initiative stuck in pilot purgatory — especially in healthcare, fintech, consumer, applied AI, and ops-heavy businesses. → sruthi@deepinteractions.ai

The Problem

Product development hasn't changed in 20 years. Write a PRD, throw it at engineering, hope it matches what users actually need.

Now teams have layered AI on top: vibe-coding through the night, stitching prompts, tools, and agents. Same problem, faster and more expensive:

  • Burned tokens
  • Burned out teams
  • Spaghetti code that still misses the customer

95% of businesses walk away from their AI pilots. Hundreds of billions in wasted AI spend, every year.

The bottleneck isn't models or prompts anymore. It's shared understanding of the customer, the product, and the codebase. Until now, there was no way to keep humans, agents, and code in sync as a product is being built. With today's reasoning models and multi-agent orchestration, couple with situated context, there is.

Our Solution

You bring the problem. We ship the product the same afternoon — alongside your team, inside the tools they already use (Slack, Figma, GitHub, Vercel, Supabase, You name it).

We don’t leave you with a spaghetti mess of a code. We bring product intelligence and power the context layer that enables your team to build in sync.

Already live with 12 businesses and 50k+ real-world usage hits. Saving companies months of work and millions in AI spend.

How can you help?

If you can warmly introduce us to any of the following, I'd be grateful:

  • Operators with a stuck AI initiative (Heads of AI, CPOs, CTOs, VPs of Engineering)
  • Healthcare & wellness companies looking to ship patient- or clinician-facing AI
  • Consumer companies (dating, fitness, fertility, social) ready to put AI in the product, not just the pitch deck
  • Applied AI startups burning tokens on coding agents that don't ship
  • Angels and operators who've shipped AI products at scale

Please contact me at sruthi@deepinteractions.ai

Team

I'm a Human-Centred AI researcher and DPhil in Computer Science at Oxford, with cutting-edge experience across Big Tech, AI labs, startups, and academia — spanning software engineering, UX, ML, and AI research. Recognised by 100 Women in AI (2025).

Around me: a founding AI designer reshaping how humans and agents collaborate, a founding engineer with decades in production systems, and GTM operators who's built customer success from zero. Advised by leading Human-Centred Computing professors, AI scientists, and brilliant Angels.

I started Deep Interactions because I kept watching brilliant teams ship broken AI. The future of AI work isn't more prompts — it's better human-AI collaboration.
