A name that holds
Finding a studio name sounds like an afternoon with coffee. In reality it's a process of elimination. A good name doesn't just have to sound good, it also has to be free: no trademark in the same field, no taken domain, no studio or game that already uses it.
Left by the wayside
Helyx sounded great but was already a registered trademark for games. Spawnlab: domain taken. Genofunk: an existing role-playing game. Helixwerk: clashes with an EU trademark for games. Each of these names would have become a problem at some point, at the trademark office, on Steam or with an unpleasant letter.
Codonwerk
A codon is three DNA bases that together define a trait. "Werk" is German for workshop. Together: a workshop where small building blocks become something of their own. The checks in the German, EU and international trademark registers, the domains and the platforms all came back clean.
The name then became the logo: a C made of two strands with three bases in teal and violet. A codon, in other words.
