Yelp doesn’t rely on surveillance-based advertising, but they’d like to change that. They have launched a program to target ads at Yelp visitors on non-Yelp platforms based on their Yelp activities. Yelp will serve the ads, so there’s not enough data sharing to break most privacy rules. Consumers may not agree: this recent Jebbit study found 53% of people object to personalized emails based on data they haven’t knowingly shared.

Zoom has announced a deal to buy cloud contact center company Five9 for $14.7 billion (with a B) in stock.  The price is an astronomical 34x Five9’s $425 million revenue and nearly 5x Zoom’s own revenue.  Zoom sees the deal as giving it a firmer foothold in the enterprise communications market, although Five9 is far from the market leader.

Treasure Data will provide its system to free for companies that are stuck in contracts with other CDPs. The trade-up program is available to companies with roughly firms with $1 billion or more revenue, that already have a competitive CDP in place. There will still be some costs for services to make the conversion but Treasure Data says these are fairly small since it has considerable experience with such projects.
