It was an honor to be in Washington, DC as a #Dadvocate for today’s Dads Day of Action in support of paid family leave for all. Huge thanks to @DoveMenCare, @PaidLeaveUS, and @alexisohanian for their leadership on this important issue.

@willbitsky @dylan522p @benthompson Spot on, Will. AI is transforming the web across search, discovery, commerce. Consumer agents are only half the story: brands will run their own agents, driving an ad boom as they guide users end-to-end. Targeting flips too - less guessing who you are, more solving what you need.

Super proud of @aperiamventures portcos @FirsthandLabs @ChaliceCustom and Swivel on AI panel at #DMSbyLUMA led by the one and only @aripap.

[Michael Rubenstein @mrubenstein99]

@antoniogm @Firsthandlabs is helping publishers sell agents, not ads. That means changing what an ad is into a multimedia, interactive, personalized experience. More revenue for pubs, better performance for advertisers.

@ericfranchi @aperiamventures @OSchiffey Wonderful to see Aperiam continuing to flourish - congrats Eric!

[Eric Franchi @ericfranchi]

I used to cover adtech so couldn't resist this one: Adtech pioneers who helped build unicorns like DoubleClick and AppNexus have launched Firsthand -- to build a platform that empowers publishers/brands to create and distribute their own AI agents
