Q&A: What Makes an On-demand Service Thrive?

On-demand services are growing exponentially, thanks to the convenience they bring to everyday routines like commuting, groceries, and food delivery. We sat down with Instacart co-founder Max Mullen and Doordash co-founder and CTO Andy Fang at Signal 2016 to find out how they coordinate an army of people to run smooth operations.

Discovering operational hurdles

Andy: With an on-demand service you have to balance requests from customers with merchants, and fulfill those requests as soon as possible. But compared to traditional marketplaces, on-demand services have a higher level of operational complexity. There are a lot of unknown variables you have to account for including demand, supply and logistics. When you're delivering in 45 minutes or less, juggling these variables in real-time can become a very tricky problem.

Max: For Instacart, we not only have customers, merchants and drivers in our operational chain, but also have shoppers placed in stores. And then there is the complicated process of sourcing the goods—where they are, selecting the best ones. Doing that well at scale is one of our biggest competitive advantages.

Balancing supply and demand

Max: Matching supply and demand is a big challenge. Early on, we started our logistics team who built a complicated capacity system that helps even out the peak times for orders. This system helps customers understand when we can actually fulfill our one hour promise and when they have to wait maybe a little bit longer.

Andy: I would say that balancing supply and demand is definitely a very interesting challenge. For example, with restaurant delivery you have very drastic peaks. So if I'm an individual restaurant owner and I want to staff my own delivery service, I don't know if I need ten drivers on the road or maybe just two. With DoorDash we work continuously to reduce those variants and sustain liquidity in our marketplace.

Achieving on-demand success

Max: Knowing exactly where the shopper is throughout the shopping process allows us to assign them the next order. We send text messages to notify the shoppers when they need to start fulfilling new orders. Then, we track how long it takes in seconds for every shopper to get notified, to acknowledge an order, to pick the first item and then their average speed per item. We use intelligent algorithms which decide who fulfills which order. After all, efficiency equals economic viability in the on-demand business.

Putting communications to use

Andy: We use communications to protect customer and shopper privacy. Twilio makes it really easy to mask the phone number when customers are interacting with our dashers. The dashers don't have access to customers’ personal number and vice versa.

Max: We also started using communications for the privacy component. But now that we have data from all the calls and texts, we can actually analyze the interactions that take place. Let’s say a customer calls support and has a four minute call. We can look into the reason why that call took so long and provide better assistance. Similarly, with Twilio APIs we can track the text message exchange between a shopper and a customer and understand where we can improve service.
