Ads vs. Odds
Does brand advertising work? Upwave (YC S12) is hiring engineers to answer that
YC ad-tech wants engineers to prove brand ads work — commenters yell “snake oil”
TLDR: Upwave is hiring engineers to prove whether brand advertising moves the needle, using AI and big data to measure “brand lift.” The community is split between calling it ad-tech snake oil and insisting careful experiments can prove impact, with privacy worries and memes fueling a spicy debate about what ads actually do.
Upwave, a Y Combinator–backed ad-measurement firm, is hiring engineers to help answer the eternal question: do brand ads actually work? The company says its platform measures “brand lift” (did people remember or like your brand more after seeing an ad?) across TV, social, and streaming, with an AI assistant named “Bayes” turning data into plain-English insights. The internet instantly split into two camps: the skeptics shouting “grift” and the pragmatists saying, “Of course brand ads work—measuring them is the hard part.” Cue the classic John Wanamaker meme (“Half my ad budget is wasted…”) popping up in every other comment, with some insisting Upwave wants to invoice the other half.
Privacy hawks bristled at “billions of impressions” being tracked, while engineers debated the ethics of building what one called “a feelings meter for CMOs.” Fans of science argued for real experiments—control groups and “holdouts”—claiming brand impact can be proven if you run proper tests. Meanwhile, comedians had a field day: “AI named Bayes writing PowerPoints to justify vibes,” “microservices bingo,” and “Congrats on your ‘lift’: people vaguely remember a blue logo.” Supporters pointed to Coca‑Cola–level budgets as proof brand spending matters; critics rolled their eyes at “LLMs writing ad decks” and asked if any of this will sell one more soda. Drama level: high, caffeine-like.
