Who Profits is a website dedicated to detailing the companies, Israeli and worldwide, that directly profit from the Israeli occupation of the West Bank and Gaza Strip.
It includes companies producing and exporting goods made in illegal settlements (e.g. crops grown on expropriated Palestinian land in the Jordan Valley), companies involved in the construction of settlements, providing infrastructure for them (like Veolia, who are building a light rail link between West Bank settlements and Israel proper, and who recently lost their contract to run Stockholm's public transport - though how much influence the campaign against them had is unknown), companies like Caterpillar providing destruction equipment used to destroy Palestinian homes and land, companies like EDS providing electronic security equipment and services for checkpoints, and many more.
The one area it doesn't cover is companies selling arms to Israel, a topic which is fairly well covered elsewhere. (Although many arms companies are listed as they also provide civil 'security' equipment and services.)
