The four questions every founder is really asking
Most founders bet on instinct. MarkLens answers the four questions instinct can't.
Every read comes back with the same shape — so you always know what to do next, not just how to feel.
? Where
Market by market.
See which cities and segments lean in and which to skip. Aim your launch, your spend, and your first hundred customers at the places already pulling for you.
? Why
The reason behind the read.
The drivers, the objections, and the triggers — in plain language. Know what makes people buy and what makes them walk, before you write a line of copy.
? What they want next
Your roadmap, from the demand side.
The unmet wants your category keeps asking for. Build the next thing the market is already reaching for, instead of guessing at the backlog.
How a read works
From a one-line idea to a verdict you can act on.
Describe what you're building.
One line is enough — product, price, market. "Cold brew protein coffee, $4.50, DTC US" gets a read.
MarkLens reads the signal.
It scans live consumer conversation across your category and pulls the read together. — reasoning powered by Claude
You get a verdict.
Sell, refine, or rethink — with the where, the why, and what to build next attached. Act, don't agonise.
Stop guessing what the market wants.
