It became a public company on the Alternative Investment Market in March 2021. tinyBuild was founded in 2011 by Alex Nichiporchik (Latvian: Aleksandrs Ņičiporčiks) and Tom Brien.

[3][4] Nichiporchik came from Latvia and had been a professional Warcraft III: Reign of Chaos player in the early 2000s, which made him enough money to drop out of high school and pursue a career in video game journalism.

Nichiporchik discovered No Time to Explain, a Flash game by Tom Brien, which he thought could be as successful as Super Meat Boy.

However, Buka Entertainment failed to communicate with tinyBuild until stating that it was forced to cancel the project, withholding the royalties.

Nichiporchik stated this experience burnt out tinyBuild, which was no longer interested in pursuing development but did not want to waste the newfound success.

[15] tinyBuild announced in February 2021 that it was to pursue an initial public offering on the Alternative Investment Market of the London Stock Exchange with the ticker symbol "TBLD".

[18] The company acquired the intellectual property rights to the bulk of Bossa Studios' games including Surgeon Simulator and I Am Bread, for US$3 million in August 2022.
