How Sundial rebuilt same-day support on Vireo

Read the story
Nadia Rehmani
Co-founder at Sundial

"We run same-day delivery across eleven markets and four languages, so the edge cases never stop arriving. Vireo read two years of our own transcripts and gave us measurable movement — 41% fewer escalations, faster resolution paths, and far less manual triage between shifts. As we push into new regions and serve close to 6.4 million people a month, that kind of partnership is what keeps the promise we make at checkout."
