michael sieverts (michael gram sieverts), Danish, living in Colombia, is a serial fraud with a history of lying, stalking and stealing. He stalked and harassed me for years: taking photos of my parents’ home, stalking me, my family, employers, colleagues and friends. Constantly spreading lies.
When I moved to Switzerland he immediately tried to follow, applied for a job at my employer out of envy, after two years of parent-funded travel and a year of unemployment in Denmark failing to find Swiss work.
In 2022 he lied on his CV (copying mine), reapplied to my employers and obtained a QA role at Zimmer Biomet in Winterthur in September 2022. He continued using my CV on his public LinkedIn until caught in March 2023.
He signed my email (and those of interviewers who rejected him in Switzerland) up for spam from Danish supermarkets and sex shops.
In 2017 he stole >300 000 DKK of chemistry equipment from university to cook meth in his parents’ apartment in Hørsholm, Denmark.
He continues to fabricate his background:
-False dates/duration of university studies
-4 years as quality engineer at Officer A/S
-2.5 years as Senior QA manager (plus sales) at Lanna Fruits, Thailand
-Founder of “Sieverts Foods” Zurich (selling Lanna Fruits products in Europe/Middle East)
-Business Development Manager at Algodao.fi
-5 months sales at Crossmint via an outsourcing firm
-Co-founder of Coldconvert.sale with roommate Sven Jauffred Pedersen (who also lied on his CV to get a role at Sygnum Bank Zürich in 2022)
- Investor at Sieverts Holding (shell created to buy his Medellin apartment through his parents’ Danish company)
He will not stop lying to appear successful. Be extremely careful: he may steal from you, harass you and your family, slander you... If he knows your name or email you have almost certainly been stalked, especially if you are a young woman.
