Iris

All your calendars and inboxes, powered by an intelligent assistant.

Iris connects all your calendars and inboxes in one place with a built in personal assistant. It connects with Gmail, Google Calendar, Maps, and more to understand your context - what you’re working on, who you’re meeting, and where you need to be - and intelligently organizes your time around what actually matters. Unlike assistants that just schedule events, Iris learns your rhythm and automates your workflow: drafting emails, moving meetings, blocking focus time, and coordinating across accounts, all with your approval. We’re building the next generation of personal AI, one that keeps you ahead.

Iris: The Personal Assistant

Hi everyone,

We’re Samika & Siddhant - cousins and co-founders of Iris. We connect all your calendars and inboxes in one place with a built-in assistant that truly understands you.

The Problem:
The problem isn’t a lack of tools - it’s that they all expect you to think like them. Between five calendars, three inboxes, and constant context switching, simple things like moving a meeting or replying to an email still take minutes of mental load. Apps like Motion or Reclaim help you plan, but they don’t understand you. They still need perfect inputs, perfect routines, perfect focus.

We didn’t need another productivity system to maintain - we needed something that worked with how we already do things.

The Solution
Iris is your intelligent personal assistant that organizes your day around what actually matters.

She connects with Gmail, Google Calendar, and Maps to understand your context - who you’re meeting, what you’re working on, and where you need to be - and then helps you act on it.
Ask Iris to reschedule a meeting, draft a reply, or block time for deep work - she does it instantly, across all your accounts, with your approval.

Unlike typical AI assistants, Iris builds around your life. She learns your rhythm, adapts to changes, and quietly keeps your day in sync so you can focus on doing the things that matter, not managing them.

The Team
We’re cousins who’ve been building together since we were kids.

Samika previously founded Solstis, worked on adaptive AI systems at CMU for a year, and studied how humans build trust in AI.

Siddhant has been coding since he was 11, he built and launched 12 consumer apps with 2500+ active users. He studied Computer Science from UCSD.

Earlier in the batch, we met Adam Cheyer (founder of Siri), who became a mentor and advisor. That conversation reshaped how we think about assistants - not as UX problems, but as deep engineering problems.

Hear from the founders

How did your company get started? (i.e., How did the founders meet? How did you come up with the idea? How did you decide to be a founder?)

We’re cousins who’ve been building things together since we were kids. Samika had already founded a company before Iris building scalable enterprise agents. Siddhant has been coding since he was 11 years old and loves building complex systems in the form of consumer applications (12 apps in production, 2500+ active users)

Iris started as something we built for ourselves. We were constantly overwhelmed by scattered calendars, inboxes, and tasks and every “assistant” tool felt either too rigid or too dumb. So we decided to build one that actually understood us, combining the reliability of deterministic systems with the intuition of LLMs.

What's the history of your company from getting started until the present day? What were the big inflection points?

We started Iris as a side project to fix our own scheduling chaos with a good user experience. The first prototype synced our calendars and emails, and within hours it was already making our days smoother. That’s when we realized how big this could be.

A major inflection point was meeting Adam Cheyer, the founder of Siri. His advice reframed how we thought about the problem - it wasn’t just a UX challenge, it was an engineering problem. We then brought on one of Siri’s founding engineers as a technical advisor, which shaped our architecture around deterministic logic combined with adaptive LLM reasoning.

That shift (from “AI wrapper” to hybrid intelligent system) became the foundation of Iris.

What is the core problem you are solving? Why is this a big problem? What made you decide to work on it?

The core problem is cognitive overload because people are drowning in context switching between calendars, emails, and apps just to stay organized. Productivity tools today still expect you to manage them. They don’t understand how you work and make you configure rules and routines that fall apart when real life changes.

We felt that pain deeply ourselves. Both of us are neurodivergent so motivation wasn’t the issue, context was. We didn’t need another to-do list but we needed something that understood our rhythm and made intelligent decisions for us.

Iris exists to eliminate that friction. It learns how you work, automates the repetitive decisions, and keeps you focused on what actually matters. This problem is universal, everyone struggles to stay on top of their time. Solving it unlocks human attention at scale.

What is your long-term vision? If you truly succeed, what will be different about the world?

In the future, everyone will have their own Iris: an assistant that actually knows them - how they work, who they meet, where they go and helps them stay a step ahead. When two people both use Iris, their assistants can coordinate directly, handle logistics, and clear out the noise before it reaches them.

At scale, this becomes the foundation for how individuals and teams organize time - from one person’s calendar to entire companies. Iris is how people will work when AI truly understands context.
