The problem

What gets in the way today

Everything looks urgent

Product, pricing, hiring, channels. Nothing says which one is holding you back.

Advice for the wrong stage

A playbook for scale does not help before first customers, and the reverse.

Updates written at midnight

Investors ask for numbers, and the monthly update gets stitched from four tools.

How Surfil answers it

Growth Score

One score from your numbers and your site, the constraint it points to and the Programs that fit your stage.

Diagnosis

The constraint your score points to, ranked by the room it has to grow.

Programs

Each stage switches on its own work, from idea to exit, in the right order.

Sprints

Short Sprints of Actions for your stage, re-planned as your numbers move.

Experiments

Design a test, rank it by ICE and read the result when it ends.

Reports

A monthly investor and board update built from your own numbers.

Competitors

Pricing, messaging and launches on a competitor's public site, tracked for you.

Your rhythm

Each day, week and month

Each day

Hear only if it breaks

Your site is read daily, and you get an email only when a passing test fails.

Each week

Do the next Action

Open your Sprint, take the top Action and tick it off when it ships.

Each month

Send the update

Add the month's numbers, then share the report with investors or your board.

FAQ

Before you ask

See pricing →

Do I need to install anything to start?

No. The test reads your public site. Connect Google and add the pixel later to unlock the pillars that need your own data.

Is there a trial?

Pro starts with a 7-day trial. A card is required, nothing is charged until the 7 days end, and you can cancel in two clicks before then.

Does it work before I have customers?

Yes. At idea and validation it focuses on the offer, the test and the data you need first. Pillars that do not apply yet never count against you.
