try this

var app = angular.module('app', []);

app.controller('CompaniesController', ['$scope', '$http', 
  function($scope, $http) {
    $http.get('json/companies.json').success(function(data) {
        $scope.companies = data; // get data from json

        $scope.techStack = []

        angular.forEach($scope.companies, function(item){
            $scope.techStack = item.technologies;
            var uniqueTech = [];
            for (var i = 0; i < $scope.techStack.length; i++)
            {
                if (uniqueTech.indexOf($scope.techStack[i]) == -1)
                    uniqueTech.push($scope.techStack[i]);
            }   
            console.log("Unique Technologies : " + uniqueTech);

        })
    });

  }
]);
