Millions of neighborhood stores that dot large and small cities, towns and villages in India and have proven tough to beat for e-commerce giants and super-chain retailers are at the center of a new play in the country. A score of e-commerce companies, offline retail chains and fintech startups are now racing to work with these mom and pop stores as they look to tap a massive untapped opportunity.

A Pune-based startup with an idea to build a logistics network using these kirana stores said today it has won the backing of a major international investor. Three-and-a-half-year-old ElasticRun said it has raised $40 million in a Series C financing round led by Prosus Ventures (formerly Naspers Ventures). Existing investors Avataar Ventures and Kalaari Capital also participated in the round.

The startup has raised $55.5 million to date, Sandeep Deshmukh, co-founder and CEO of ElasticRun, told TechCrunch in an interview.

Most of these kirana stores each day go through hours of down time — when the footfall is low and the business is slow. ElasticRun works with hundreds of thousands of these stores across 200 Indian cities to have them deliver goods to other kirana stores and consumers.

Supplying goods to these stores are FMCG (fast moving consumer goods) brands that are trying to reach the last mile in the nation. Nearly every top FMCG brand in the country today is a partner of ElasticRun, said Deshmukh.

It’s a win-win scenario for every stakeholder, Deshmukh said. Stores are getting access to more goods than ever, and also getting the opportunity to increase their business in slow hours. And for brands and e-commerce companies, access to such a wide-reaching delivery pool has never been easier, he said.

Deshmukh, who previously worked at Amazon and helped the e-commerce company build its transportation network in India, said he and his other co-founders built ElasticRun because traditional logistics networks are beginning to show cracks.

India’s trucking system, for instance, has long been a laggard in India’s economy. A World Bank report five years ago noted that lorries in India spend about 60% of their time sitting idle.

Because there is a digital log of each transaction, Deshmukh said the startup has a good idea about the financial capacity of these kirana stores. This has enabled it to connect them with relevant financial partners to access working capital, he said.

Deshmukh said the startup will use the fresh capital to on-board more neighborhood stores and deepen its penetration in the country. ElasticRun is also working on new products to expand its offerings for brands and kirana stores and improving its analytics and machine learning algorithms to tackle larger scale.

“By working with the network of small stores across the country, we solve that problem while helping the store owners grow their businesses at the same time. In addition, offering a flexible logistics extension to consumer goods companies to directly reach these small retail shops is a huge advantage over traditional distribution networks,” he said.

In a statement, Ashutosh Sharma, head of Investments for India, Prosus Ventures, said, “ElasticRun is one of those rare businesses that identified a massive need in the market, matched it with a local solution paired with technology, for the benefit of all parties involved. Consumers get faster deliveries and greater choice of goods, store owners realize increased revenues and touchpoints with their customers, and consumer goods companies get better access and insight into their target audiences.”

Update: At an event organised by Prosus Ventures this evening, Deshmukh said while ElasticRun is focused on building solutions for India, in the future he may consider expanding to some Southeast Asian markets that are facing similar challenges.
