Game studio and Lab / Colombia
Quiet name.Loud worlds.
Silent Thread is a game studio from Colombia. It started as the work I did after hours.
01 / Origin
Made after hours.
For years I built products for other companies.
At night I built my own games and tools.
Silent Thread is that night work becoming a studio.

02 / The founder
Esteban Estrada Founder & Director
Started at sixteen. Still on the night shift.
I got my first job at sixteen, at a startup that threw me into the deep end. No title, no hand-holding: figure it out, ship it, own it. I never stopped.
Since then I've built media and radio apps for a company in Boston, a marketplace on web and mobile, AI products, and payments infrastructure as a senior engineer. All of it with someone else's name on it.
At night I build tools for AI coding agents in the open (Guildhall, Cockpit, mcpx, Hindsight) and games. Silent Thread is where that work finally gets a name.
“Being senior is a mindset, not a label you wait to be handed.”
