Breakpoints: pricing pressure, operational complexity

The bottleneck shifted

Execution got easier.
Decisions got harder.

A new launch still costs months and real money. Surveys tell you what people say; markets move on what they do. Sunlight reads the market and shows your next move.

How it works

From decision to tested experiment.

Model the Decision

Sunlight builds a grounded model of the decision in front of you: the market you’re entering, the customers, competitors, and channels that will shape the outcome.

Simulate the Response

Evidence-grounded personas (customers, competitors, demand channels) react across multiple rounds, so you see how the market is likely to respond before you spend a cent.

Get the Experiment

Sunlight hands you the move: the sharpest angle in, the breakpoints to watch, and a concrete experiment you can run to validate it for real.

Built for the people making the call

Founders & Operators

You can't test every market and channel by launching into each one. Sunlight simulates the decision first, then tells you the sharpest way in, and the experiment to prove it.

Growth & Expansion Leads

New market, new channel, new launch: see how customers and competitors are likely to respond before you commit the budget, then run the experiment Sunlight maps out.
