Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Texas. They belong to that state's ranking, not this one.

What moved since the last measurement

This is the first measurement of this cell, so there is nothing to compare it with yet. The next measurement will show what moved.

Stability is normal. AI answers in industrial categories change slowly, and a cell can go several measurements with no change in the top ten.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

  1. 1Best aggregate and stone materials companies in Texas
  2. 2Who supplies washed construction sand and gravel in Texas
  3. 3I need a Texas aggregate and stone materials partner for ongoing ready-mix concrete production, who should I talk to
  4. 4Top aggregate and stone materials suppliers in Texas for civil construction buyers
  5. 5Which Texas aggregate and stone materials suppliers can provide DOT-spec crushed stone and certified gradations
  6. 6List 20 aggregate and stone materials companies in Texas with their specialties.the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.

Where AI drew its answers from

These are the sources the answers in this cell leaned on most, ranked by how many of the named companies each one stands behind.

Texas in context

Texas ranks 2nd of 3 measured states in this category. Each bar is the share of that state's tracked companies that AI assistants named at least once; across every measured state in this category the share is 15%.
