GRETA &
HANNES
February 7th, 2026 · Philadelphia, PA
Please join us on february 7th, 2026 as we celebrate our wedding in philadelphia.
Greta’s Story
From (North) West Philadelphia, born and raised… (you know the rest). Greta’s the oldest of three athletic, creative sisters, daughter of a brilliant lawyer and talented master metalsmith, and proof that you really can be both practical and sparkly. She played lacrosse at Stanford, studied design and engineering, and went on to start Sequel, a women’s health company that’s as bold and smart as she is.
Hannes’s Story
Hannes grew up in Larchmont, NY with a German dad who talks economics, an artist mom who sees the world in color, and a doting, never bossy sister. He played football & rugby at Stanford, then headed to San Francisco to found Blumen, a company that automates permitting workflows, #slay. Equal parts steady and silly, he’s known for fixing things and occasionally losing his wallet.
Their Story
G&H circled each other at Stanford for years but didn’t actually meet until 2021 — post-COVID, post-chaos, and somehow perfectly timed. They need a Vespa bumper sticker that reads “Founders who found each other.” These days, you’ll find them hiking, biking, cooking, and laughing their way through life in San Francisco — still calm, still stoic, still very much in sync.
