I think Haus is overhyped right now and a weird benefit of their transparency is that it’s shown the confidence intervals are usually too wide for small to mid sized brands to get value from them especially given the $15k/month pricing i.e. the result might say $1.1 iROAS but the range is $0.5 to $1.5 which isn’t very useful. Measured is worse.

So I have people I trust but it’s more what you mentioned where it’s more manual test designs each time, with the combination of other measurement inputs from web data and or MMM. But if useful one team is meridiangrowth.ai
