You don't have any data that you're submitting! Try adding this line to your ajax:
data: $('form').serialize(),
Make sure you change the name to match!
Also your data should be submitted inside of a form submit function.
Your code should look something like this:
<script>_x000D_
$(function () {_x000D_
$('form').on('submit', function (e) {_x000D_
e.preventDefault();_x000D_
$.ajax({_x000D_
type: 'post',_x000D_
url: 'company.php',_x000D_
data: $('form').serialize(),_x000D_
success: function () {_x000D_
alert('form was submitted');_x000D_
}_x000D_
});_x000D_
});_x000D_
});_x000D_
</script>
