Index Exchange

We are a global advertising supply-side platform (SSP) that helps media owners get the most out of their content and increase advertising revenue across different screens and ad formats. We also help marketers reach consumers using our ad technology. We started in 2003 as Casale Media and launched the Index Platform in 2011 to make real-time transactions between media owners and marketers easier. In 2015, we officially rebranded as Index Exchange.

Over the years, we have helped shape industry standards, co-authoring OpenRTB specifications in 2011 and OpenRTB 2.6 in 2022. We were early adopters of header bidding and launched the Wrapper in 2016 to improve customer performance. In 2019, we launched IX Labs, our venture arm, and introduced Client Audit Logs to improve transparency. We rebuilt our exchange for omnichannel growth in 2021, and in 2022, we acquired Rivr, a machine learning company. In 2024, Index Marketplaces launched in a closed beta, offering a platform for sell-side decisioning, and we eliminated made-for-advertising (MFA) sites across our exchange. We handle hundreds of billions of requests daily and operate our own infrastructure.

Our vision is total market efficiency, meaning we want to eliminate inefficiency and reduce costs in the programmatic ecosystem. We work to uphold the integrity of the ecosystem. Our core values include:

• Change. Embrace it. Lead it. We are agile and constantly improving in the evolving ad tech industry.
• Support each other. It matters. We create a supportive environment where employees can be their best.
• Learn it. Then teach it. We promote curiosity, problem-solving, and knowledge sharing.
• Build real trust. It doesn’t just happen. We focus on conscious effort and openness to build trust and transparency.
• Be intentional. Launching is fun. It’s the landing that counts. We act with purpose and see initiatives through to completion.

We foster a culture focused on innovation and driving ad technology forward. We pride ourselves on an open environment where people feel connected and supported, encouraging employees to be their best both at work and in their personal lives. We maintain high standards for quality, prioritize continuous learning, and encourage strong relationships and collaboration among colleagues.

Work is hybrid; employees typically work from the office Tuesday through Thursday and can work remotely the other two days. Employees can also work from another location for four weeks each year. We are committed to diversity, equity, inclusion, and belonging (DEI&B), with programs, employee resource groups, company-wide training, and industry collaboration to build an inclusive culture. We also prioritize sustainability, with an employee-led Index Net Zero interest group dedicated to building a sustainable business. We support professional growth through ongoing learning, development opportunities, sponsored memberships in organizations, and by encouraging participation in mentorship programs and industry working groups.

We offer health, dental, and vision plans for employees and their dependents. Benefits include paid time off, health days, personal obligation days, and flexible work schedules. We provide retirement matching plans, stock options, and equity packages. Parental leave is available to birthing, non-birthing, and adoptive parents. Employees receive an annual well-being allowance, fitness discounts, group wellness activities, and commuter benefits where available. An employee assistance program and a mental health first aid program are also available. Additionally, we offer one day of volunteer time off per year and a donation-matching program. We also provide many resources and programs for continuous learning.
