Halo Cars, a rideshare advertising startup, was founded in 2018 by Kenan Saleh and his co-founders. The company allowed drivers to earn extra money by installing Halo Cars hardware and displaying ads on and in their cars. After testing the concept during college, they took the company full-time and raised funding. Halo Cars grew rapidly, but its early growth was fueled by a high-touch onboarding process that involved manual interventions and hours of work per driver. The team turned to automation with Zapier, a workflow automation software, which allowed them to create custom automated workflows to handle these manual tasks. By automating the process, they reduced their hands-on time from hours to minutes and increased scalability. The team found that people were excited about the automation, as it eliminated an annoying process that everyone had to do. After introducing Zapier, the team continued to automate other processes, including sales team workflows and equipment issue reporting. Even after being acquired by Lyft, the company relies on automation with Zapier to connect apps like Airtable, DocuSign, Twilio, Google Sheets, and Google Drive. Kenan considers Zapier as "the glue" that ties their systems together, using it to send data into Airtable and trigger workflows in other apps. The team uses Zapier to save countless hours of manual time, which would have been difficult to quantify but is estimated to be tens of thousands of hours over the lifetime of the business.
