Main / Blog / How to Build a Successful Two-Sided Marketplace?

A two-sided online marketplace platform is like a modern El Dorado. Creating a space for sellers and buyers to interact benefits both, as well as the platform owner.

At Dinarys, we receive many requests to build two-sided marketplaces, inquiries how much does it cost, and so on. We can and do perform this type of work frequently, and in this article we’ll share some of that experience.

We’ll go through the steps to create a two-sided marketplace platform. More importantly, we’ll also show you how to create the community that will use the platform. If the platform can not attract buyers and sellers, it isn’t worth much.

Get it right, and the rewards are huge. E-commerce provides huge opportunities for retail businesses. According to Statista, the worldwide number of online shoppers in 2016 approached 20 million.

There is a bit of a “chicken and the egg” issue here. An online marketplace is only as good as its users. So how can you bring in that initial set of users to kick off the enterprise?

Let’s dig in.

What is a Two-Sided Online Marketplace Platform

What is a Two-Sided Online Marketplace Platform

The term refers to a website where buyers and sellers meet. The site acts as an intermediary or middleman, facilitating transactions, product discovery, payment, and so on. The platform  owner takes a percentage of each transaction.

The platform generally does not offer its own products. Instead, the owner controls relations between online shoppers and third-party creators. It may seem difficult at first, but many of the most successful startups today are two-sided platforms.

As an example, let’s look at Uber. Boiled down, the company simply connects riders and drivers. Drivers provide their own cars and driving expertise. Riders pay Uber, which takes a percentage, and passes the rest on to the drivers.

Uber was established in 2009, and is now one of the largest two-sided marketplace platforms in the world. The interesting thing is, Uber doesn’t provide any of its own cars or drivers. It’s a great example of a disruptive commercial model, but without riders, there would not be any necessity for drivers. Conversely, without drivers, riders would never use the service.

There are plenty of other examples of this type of business. Etsy, Handy, Airbnb, and eBay all stand out. These platforms act as a regular between two parties, providing a space for collaboration, and setting rules and standards.

But how did they get started?

There are plenty of other examples of this type of business. Etsy, Handy, Airbnb, and eBay all stand out.

So, as we said, there are three main factors in creating a successful two-sided marketplace.

The trick is developing all three in synchrony.

What tactics should a business use to accomplish that task and enjoy success in the two-sided marketplace field? Where should you start?

Focusing on a particular niche is crucial to building a two-sided marketplace

Find Your Niche

Focusing on a particular niche is crucial to building a two-sided marketplace. Your website should offer unique, specific products and services that are interesting to a clearly defined audience.

Our advice is always to choose a niche you already have experience in, or passion for. By starting with what you know, you’ll have a better understanding of your customers’ problems and needs. You’ll likely already have ideas of holes in the marketplace that you could fill, or features that users can’t turn down.

Current Trends in Two-Sided Marketplace Platforms

Best two-sided marketplace examples

Before you invest in creating a two-sided marketplace platform, you should take a close look at current trends. New players in the space arise every year, and paying attention to the most successful ones is simply good business.

For example, many successful new two-sided marketplace businesses are focused on vertical markets. That means the goods and services sold all relate to a single industry, or vertical. Some recent examples of this include markets devoted to accounting, banking, agriculture, and others.

Here are a few such projects that are worth studying. If you’re founding your own startup in the space, these will give you some ideas.


When Uber began, it was only available in the city of San Francisco


When Uber began, it was only available in the city of San Francisco. The company had trouble attracting drivers, and started to pay them for idling.

Etsy One of the greatest examples of the business model,


One of the greatest examples of the business model, Etsy was one of the first to build a community around its niche market. Under the umbrella of home crafts, Etsy offers a wide range of offline activities, including workshops, lectures, and more.

Etsy also stands out for the way in which it turns sellers into buyers, and vice versa. They leverage the idea that most craftspeople, even ones selling their goods online, prefer to buy from other craftspeople. Buyers and vendors intermingle, developing the platform and increasing Etsy’s bottom line.

Features of a Great Two-Sided Marketplace

There are many other successful two-sided marketplace platforms to learn from. For now, though, we’ll share some specific tips on what features a platform needs. 
1. Simple signup/login process
The simple and quick login process is a must for online marketplace success. For that, allow users to sing into your marketplace with their Facebook, Google+ account. You can offer at least two-three options, making logging process even more enticing. 
During the sing up, ask only for relevant information and let users retrieve name/password.

2. Vendor account page
Vendor page should be user-friendly and convenient. In should include the account settings to editing payment methods.
For a vendor account, we recommend the following features:

PCI Security Standards comprise 12 requirements to all website that accept/keep payment information. SSL certificates are also called digital certificates because they are applied while setting up a secure connection between browser and server.

Immediate message-passing helps to build an ongoing relationship and pave the way for loyalty, trust, and regular customers. 

Scaling Up

Once you have a functional small business, it’s time to look at scaling up. This is the dream for any online business owner.

As you plan development of your two-sided marketplace, keep large vendors in mind. Cultivate these relationships as early as possible, and plan future additions to accommodate them. Large vendors already have their own customer base, and they can bring huge swaths of them to your marketplace. They’ll also help cover the supply-demand gap, flooding the market with product.

Of course, creating a two-sided marketplace isn’t quite that simple. Most startups struggle with what we call the chicken-and-egg problem. If you’re not familiar with this common dilemma, keep reading.

It’s the same for two-sided marketplace platforms. A platform needs sellers to offer anything to buyers, but sellers won’t come if there’s no one buying

The Chicken or the Egg Dilemma

Which came first? The chicken or the egg? The chicken hatches out of the egg, but the egg is laid by the chicken. So, how do you get one without the other?

It’s the same for two-sided marketplace platforms. A platform needs sellers to offer anything to buyers, but sellers won’t come if there’s no one buying.

This can be a real challenge for startups and unknown businesses in any business model, but especially in two-sided marketplaces. For this model to work, it needs to have both buyers and sellers almost from the start, so that they attract and support each other.

The answer is to create an alternative way to attract one side or the other. For Uber, the answer was to pay drivers even when they had no riders. For others, the answer may be to offer value-add enticements to buyers. A community membership or informational resource can be a great way to bring buyers into a store that is light on merchandise.

Next Steps to building a two-sided marketplace

Platform development isn’t the only important piece of creating a successful online business. When planning, be sure to budget for marketing and advertising, SEO, content creation, maintenance, and support. Before you launch your two sided marketplace for startups, have these resources ready.


Have a marketing plan ready to bring users to your site as soon as it goes online. Postcards or leaflets can work well, especially in a local geographic area. Email blasts and social media are also useful.

Customer Service

Treat every new customer like gold. If you make them feel significant, they will turn into loyal advocates for your platform. A small gift or a hand-written thank-you note to buyers and sellers can do wonders, and always ask for feedback via email.

Above all, be responsive to their communications and requests. Nothing will turn off a new client faster than being ignored.
