As commented, check if with enough text the title is still too low for you.
If this is true, think twice if you're right. Most "standard" classes have a well designed default style and change this probably is not as elegant as you think. Extra space before of the title emphasized it discrete but effectively. Maybe it is worth to check before similar document class (for example, for an article compare article, paper,scrartcl, etc) and reduce margins (a little) with package geometry.
If despite all you are decided to change the tile format, it is possible add a negative vertical space with \droptitle (that need the package titling) or simply add a \vspace inside the title without extra packages. Uncomment the corresponding lines of this example (remove the first % only of each line) to see the effect of each option:
\documentclass{article} % Try also "scrartcl" or "paper"
\usepackage{blindtext} % for dummy text
% \usepackage[margin=2cm]{geometry} % to change margins
% \usepackage{titling} % Uncomment both to
% \setlength{\droptitle}{-2cm} % change title position
\author{Fran}
\title{%\vspace{-1.5cm} % Another way to do
A Minimal Working Example}
\begin{document}
\maketitle
\Blinddocument
\end{document}
Other packages as savetrees or wordlike have global effects in all the document (margins, spacing) but also raises the title.
Of course, you can also make a title from scratch. Redefining \maketitle to put a maximum of information in a page show some ways to do. See also Custom title page in report or book class?
amsartorarticle. Also you need some contents to produce some text and change the vertical spacing. – Sigur Dec 28 '12 at 12:01lipsumpackage to your preamble (\usepackage{lipsum}) and issue a\lipsumafter the\maketitle. This should output a few paragraphs of blind text, which should push the title up. LaTeX has some expectations about where text should be and is also very generous in the top spacing before the title, so it will not be all the way at the top (in a single column document). @egreg's comment should point you to a handful of very useful solutions to your current problem. – Ricardo Dec 28 '12 at 14:35
