"I found out a competitor dropped their price three days after my sales had already tanked."
I check manually when I remember — which means I usually find out too late.
Helium 10 is powerful but I need an hour just to understand what happened.
Nobody covers Otto properly. On my second-biggest channel, I'm flying completely blind.
By the time I notice the buy-box moved, I've already lost three days of margin.

Every briefing is hand-built. That's strategy, not a workaround — we want to know what makes a briefing good before we automate it. You get the founder's full attention.
A recommendation engine on top of our data pipeline produces the recommendations automatically. You get your briefing at 7am — without someone writing it at night.
One-click actions. You read the briefing, click "Adjust price," and etrendo applies it via the Amazon SP-API. Only once we've earned the trust to do that.
