Your next big decision
could cost you everything.
Most startups don't fail from bad luck. They fail from one decision made at the wrong time —
hiring before demand, scaling before systems, pivoting on gut feeling.
SarathiOS evaluates your decision before you execute. It flags what you're missing. It stops what would hurt you.

The Problem
Startups don't fail from
lack of effort.
They fail because of decisions made in uncertainty.
Building without real demand
Scaling before systems are ready
Burning cash without visibility
Repeating the same mistakes
You're making 10+ high-stakes calls every week — hiring, spending, pivoting, scaling —
all under pressure, all without a system.
Most feel right in the moment. That's exactly when they're most dangerous.
Most feel right in the moment. That's exactly when they're most dangerous.
There is no co-pilot for founder decisions.
Until now.
Until now.

It understands you.
SarathiOS tracks how you make decisions

The Name
Why we called it Sarathi.
In the Bhagavad Gita, on the eve of the war that will define his life, Arjuna — the world's greatest archer — freezes. He has the skill. He has the army. He has the conviction. But standing at the front of his chariot, looking across the battlefield, he cannot move. The decision is too large.
Standing beside him is Krishna. Not as a warrior. Not as a god. As his Sarathi — his charioteer.
The Sarathi does not fight the war. He does not pick up the bow. He holds the reins, he sees what the warrior cannot see from inside the moment, and at the instant of doubt he speaks the clarity that lets the warrior act.
That conversation became the Gita. Three thousand years later, the founder is Arjuna. The market is the battlefield. The decision is the moment of doubt.
We didn't pick this name because it sounds rare. We picked it because the relationship is exact.
SarathiOS doesn't fight your war. It sits beside you, sees what you cannot, and helps you decide.
Our Mission
We exist to stop
one fatal decision
from ending your startup
01
Give every founder a system to validate decisions before executing — not after.
02
Make founder blind spots visible before they cost runway, team, or momentum.
03
Build the operating layer that turns instinct-driven builders into signal-driven leaders.
The Founder
Nishant Mhatre
Serial OS Builder · Founder of Three Operating Systems · Managing Partner, Hestia Villas
25+ years building at the intersection of technology, real estate, and venture. Nishant led large-scale digital transformation programs across the USA, UK, Europe, Australia, and India before turning his attention to a single mission: building operating systems that eliminate the chaos founders, homeowners, and individuals face every day.
He is the founder of three distinct OS platforms — each targeting a different layer of decision-making and execution. SarathiOS helps startup founders validate high-stakes decisions before they execute. HandleLife OS brings AI-powered life management — tasks, finances, family, and digital safety — into one privacy-first system for individuals. And HSIOS™ is India's first luxury home execution OS, bridging architectural design with on-site construction to deliver premium interiors exactly as designed, on budget and on schedule.
The common thread: Nishant builds systems for the moments where the gap between a good decision and a bad one determines everything.

Common Questions
Before you ask Google
Why not just use ChatGPT?
ChatGPT gives you answers. SarathiOS builds a model of how you specifically make decisions — tracking your patterns, biases, and blind spots across every decision over time. It gets more accurate the longer you use it.
Is this for early-stage or growth-stage founders?
Both. Early-stage founders use it to avoid premature scaling and wrong hires. Growth-stage founders use it to catch systemic blind spots before they compound across teams and burn rate.
What does it cost?
Open is free forever (3 evaluations/month). Founder is $49/mo for unlimited decisions, memory, and behavioral intelligence. Captain is $149/mo for co-founder teams (up to 5 seats). Fleet is custom pricing for VCs and accelerators. Annual billing saves 20%. See full pricing →
Is my data private?
Yes. Your decisions are encrypted and never shared or sold. You own your data and can export or delete it at any time. See our Privacy Policy.
How fast can I start?
Instantly. Evaluate your first decision right here with no signup required. To unlock decision tracking, pattern memory, and the full Demand-Supply-Processing breakdown, open the OS at os.sarathios.com and create a free Open account.
How is this different from Notion or spreadsheets?
A spreadsheet doesn't know that you've been overconfident on hiring decisions three times. SarathiOS does. It applies your actual decision history and known founder-failure patterns to evaluate what you're about to do.

Don't make your next
mistake alone.
Run it through SarathiOS before you execute.
Founders using it have caught decisions that would have burned months of runway.
One founder paused a sales hire after a HIGH RISK score on demand validation. Three weeks later the signal still hadn't come, saving them an estimated $50k in burn.
Named case studies are published with each founder's permission after a decision plays out. Want to be one? Open SarathiOS →
