How it works

From problem to data in three steps.

  1. Pick a tool

    Each tool solves one problem. Its page says what it does and what it cannot do, before you pay.

  2. Run it in one click

    The default settings work as they are. Run the tool from your own Apify account, or set it to run on a schedule.

  3. Pay per useful result

    Failed, empty or unreliable results are never charged. Set a spending cap and the tool stops before it.

Why we build

We love solving people's problems with data. Every tool we build starts with one real problem someone is stuck with, and does one job well.

The Sillage Data team

How we work

Four rules. No exceptions.

  • Pay per useful result

    You pay for results that work. Failed, empty or unreliable results are never charged. Set a spending cap and the tool stops before it.

  • Public data only

    Public web pages and official data access. We never log in to anyone's account and never collect personal contact data.

  • Honest limits

    Each tool's page says plainly what it cannot do. You read the limits before you pay, not after.

  • Answer within 6 hours

    A question, a bug, a missing field: we reply within 6 hours.

Stuck doing something by hand? Send it to us.

A price to watch, a market to understand, a task nobody wants to do by hand. If the data is public, we may be able to build a tool for it.

  1. Describe the problem.

    What data you need, which public site it comes from, how often, and what it is for.

  2. Get our answer within 6 hours.

    A clear yes, a clear no, or what it would take. With the limits, upfront.
