Tech Companies In Chicago You Should Know About

By | February 1, 2024

The city of Chicago is known for its bustling downtown, diverse dining scene, and world-class performing arts centers. In addition to its attractions, the city also offers a tech community with an abundance of startups.

With such a large population and so many talented people, it’s no surprise that there are an abundance of tech companies in the city.

If you’ve been to Chicago in the past few years, you’ve no doubt noticed it’s quickly becoming one of the great tech hubs in the country.


The city is well-known as a great place for businesses because of its low cost of living, excellent public transportation system, and access to key universities like Northwestern University.

While there are other great tech hubs around the country (Silicon Valley, New York City, and Boston), this list focuses on some companies operating out of the Windy City with headquarters located in Itasca or Lake Forest so they don’t have to take on any additional taxes.

1. Software development company

Honest Inc. is a computer software development company that provides customized solutions to restaurants and retail chains. Founded in February 2017 by former GoDaddy employees, Honest Inc.’s headquarters is located in Chicago, IL.


The Honest team is located in New York City and Los Angeles, CA, in addition to Chicago. Honest is backed by leading venture capital firms and has raised $30 million in funding from investors including Y Combinator, Sam Altman, and Foundry Ventures.

2. Data and exchange platform

Zagso’s core focus is on the $74 billion flower industry and creating a platform that connects florists to customers. Zagso’s platform allows customers to browse, sort and order flowers from local florists at a low cost and with a convenient, trusted experience.

3. Marketing automation software

Rally is a marketing automation software company based in Lake Forest. It was founded in 2016 by Samir Arora and Parul Sehgal. Rally provides marketing software that helps businesses manage and track their marketing activities across channels and devices.

The company was named to the 2018 Inc. 5000 list of America’s fastest-growing companies. Rally was named to the Inc. 5000 list while experiencing rapid growth — the company had just two full-time employees in 2016 and has more than 60 employees today.

That growth has come in part thanks to Rally’s marketing automation software. Rally’s marketing automation software lets businesses manage and track their marketing activities across channels and devices. Rally’s marketing automation software is built on the idea of “prescriptive marketing.”

With prescriptive marketing, businesses can set specific rules for when messages are sent to specific groups of customers or from specific sources. For example, if a customer has clicked on one of your emails, you can automatically send them a message about your latest sale.

Or if a customer starts viewing your ad, you can automatically trigger a sequence of actions in your marketing software.

4. Cloud-based video platform

Mastr is a cloud-based video advertising platform. Founded in 2013, Mastr was originally called Mettle and was one of the first companies to bring in-video advertisements to YouTube.

Today, the company has raised $22 million from investors including FirstMark Capital and North Bridge Venture Partners. Mastr’s technology helps advertisers create digital video ads that are displayed on YouTube, Facebook, and other digital video platforms.

These ads are viewable across devices and platforms, enabling users to easily skip the ad and continue watching their favorite content. Mastr’s cloud-based technology is also scalable, which enables Mastr to scale quickly to meet the needs of its growing customer base.

The Mastr technology was originally developed by the founders in the founders’ garage and is now a nationally recognized brand.
