Interview with Dr. Mark Grether, GM of PayPal Ads
Transition from Uber Ads to PayPal Ads
Ari Paparo (00:00):
"Mark was on the podcast about a year ago when he was the head of Uber ads. So we're going to ask him about that change and what's going on at PayPal and a lot of other really interesting stuff."
Dr. Mark Grether joins the conversation to shed light on his transition from leading Uber Ads to spearheading PayPal Ads. Having joined PayPal a year ago, Mark provides a comprehensive overview of PayPal's multifaceted business and the strategic direction of its advertising division.
Overview of PayPal's Business Units
Dr. Mark Grether (02:27):
"PayPal is PayPal itself. We all use PayPal to make online transactions. Venmo is also a part of the PayPal organization... We also have Honey, our browser extension, which helps people to save money as they shop online."
Mark outlines the primary components of PayPal’s ecosystem:
- PayPal: Facilitates online transactions, widely recognized globally.
- Venmo: A social platform enabling peer-to-peer transactions and sharing user activities.
- Honey: A browser extension designed to help users save money through discounts and deals while shopping online.
With operations in over 200 markets, PayPal boasts access to 30 million merchants and serves 400 million consumers, accounting for 25% of global commerce. This extensive reach provides a robust foundation for PayPal Ads to leverage vast amounts of transaction and intent data.
PayPal Ads’ Unique Selling Proposition: Transaction and Intent Data
Dr. Mark Grether (04:41):
"The starting point of the PayPal advertising business is the transaction data... We're using that, the transaction data to have a really, really deep and rich understanding for consumers what they purchase online and offline."
PayPal Ads differentiates itself by harnessing both transaction data from PayPal and Venmo, and intent data from Honey. This combination offers a 360-degree view of consumer behavior, capturing not only what consumers purchase but also where, when, and how they make these purchases.
Mark emphasizes the advantage of this data-driven approach over traditional retail media:
"The big difference between PayPal and the retailer is a retailer who's very deep, but it's very narrow versus we are sitting horizontally across all the merchants... That's very attractive for advertisers who typically sell their products not only on one single merchant website."
This horizontal integration across multiple merchants allows advertisers to assess and optimize market share and incrementality across diverse platforms, addressing key metrics that CFOs and marketing teams are keen to understand.
Advertising Products Offered by PayPal Ads
Ari Paparo (07:38):
"What products can an advertiser currently buy from you guys?"
Dr. Mark Grether (07:38):
"There are basically two main products. The first one is they can run advertising campaigns on our own properties... Secondly, we launched recently what we call offsite ads, meaning they can also leverage our transaction data in the form of PMPs and PGs offline programmatically with our SSP partners."
PayPal Ads offers two primary advertising solutions:
- On-Platform Advertising: Advertisers can run campaigns directly on PayPal, Venmo, and Honey, tapping into the active user base of these platforms.
- Offsite Advertising: Utilizing PayPal’s rich transaction and intent data, advertisers can programmatically target audiences across the open web through Private Marketplaces (PMPs) and Programmatic Guaranteed (PG) deals with Supply-Side Platform (SSP) partners.
Mark highlights the flexibility and depth of targeting available:
"Absolutely, you can do that."
This granular targeting allows advertisers to reach specific consumer segments based on recent purchasing behavior, interests, and transactional patterns.
Geographic Scope and Future Plans
Dr. Mark Grether (11:48):
"We have the US right now live, we have the UK and Germany and those are the three markets that we focused on first."
Initially focusing on the US, UK, and Germany, PayPal Ads plans to expand its geographic footprint beyond these markets. Mark teases upcoming announcements related to AI and commerce media, signaling innovative directions for the platform.
Consumer Behavior Insights from Venmo
Dr. Mark Grether (13:10):
"One thing that people use quite often is pizza... it's a lot about beauty... Lipstick, stuff like that together to let's say a Sephora."
Venmo’s social aspect provides unique insights into consumer behavior beyond mere transactions. Commonly used emojis and transaction notes reveal interests and social interactions, such as frequent purchases of pizza or beauty products. This "shadow commerce" aspect enables advertisers to understand social purchasing dynamics and tailor their campaigns accordingly.
Commerce Media vs. Retail Media
Dr. Mark Grether (15:44):
"If you want to say commerce media, I think that's a broader term... I think commerce media is a little bit closer to what we are doing."
The discussion culminates in defining PayPal Ads’ positioning within the industry:
"Commerce media is a broader term... it is the power of the transaction data across all merchants."
Mark advocates for the term "commerce media" to encompass the wide-ranging data and cross-merchant insights that PayPal Ads leverages, distinguishing it from the more narrow focus of traditional retail media.
