Marissa is from the Latin maris (of the sea) — a 20th-century American elaboration of Marisa, ultimately from Mary. At her appointment she was six months pregnant with her first son; her two weeks of maternity leave became a national debate about American maternity policy. Founded Lumi Labs in 2018 (now Sunshine Contacts).
Subject of countless tech industry profiles.
Marissa does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Marissa reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
