JAKARTA, Nov 30 (Reuters) - At a makeshift kiosk outside her home in a South Jakarta backstreet, 39-year-old Julaiha stands at the front lines of a multi-billion-dollar battle over one of the richest opportunities in the global digital economy.

Along with goods such as instant noodles and cigarettes, she sells insurance and offers a service to pay utility bills. Though Julaiha has never had a bank account, she can help customers apply for small loans or order products from the internet.

Julaiha, who uses only one name, last year eagerly became an agent for Singapore-based Grab, a company known as the Uber of Southeast Asia for its ride-hailing service. Her husband, a motorcycle-taxi driver, also works for Grab.

"I used to have work hard in a shop," Julaiha said. "Now I work at home, press the phone, and earn money."

Their recruitment is part of Grab's efforts to muscle in on Indonesia - the home of rival Go-Jek - as the firms vie to bring banking, e-commerce, ride-hailing, food-delivery and other services to every corner of Southeast Asia.

The goal is to become the indispensable "super-app" for countries with a collective population of over 650 million, with the most fiercely contested front now shifting away from their roots in ride-hailing to financial services.

"The majority of people in Southeast Asia don't have bank accounts," said Jixun Foo, managing partner for GGV Ventures and an early Grab backer. "It's a massive opportunity."

The land-grab has attracted billions in funding from marquee names.

Backers for Grab include SoftBank Group Corp, Microsoft Corp, Toyota Motor Corp and Uber , whose Southeast Asia business it acquired in March.

The firms' similarities are striking. Both were founded a year apart as ride service companies: Grab as a taxi-booking app in Malaysia while Go-Jek organised an informal sector of motorcycle taxis - a key way to get around Jakarta, a mega-city with no metro system and epic traffic jams.

With cut-rate prices that made their services accessible in low-income countries, they quickly gained millions of users. Both are even led by friends - Go-Jek CEO Nadiem Makarim went to Harvard Business School alongside Grab co-founders Anthony Tan and Tan Hooi Ling.
