I work in marketing, and for most advertisers, Google, Meta and TikTok are where the marketing dollars flow. Beyond that lies the scrapheap of experimental channels: the Reddits, the Snaps and whatever else got a test budget this quarter. At the very bottom of the pile sits Pinterest.

It's been around for over 15 years, and surprisingly enough it makes over $4.5B in revenue with a user base that's slowly but surely growing. Unlike Google and Meta, which have been spending heavily on AI infrastructure, Reddit, which is licensing its content to AI companies, and Snap, which always seems to be in the news for a misguided hardware launches (2K AR glasses anyone) , Pinterest has stayed relatively staid.

I valued it at ~$20/share; and is currently at ~$21.95 today.

Revenue: $4.6B trailing, growing ~16-18% a year; I assume it slows to ~5% and roughly doubles over 10 years.

EBIT margin: ~16% after capitalizing R&D (7.6% reported); I assume it grows to ~20% over 10 years.…
