Sparkacus

Sparkacus OÜ designs, builds and operates its own consumer software, chiefly the GoJars brand. GoJars offers apps for web, iOS and Android for finding local services and keeping everyday household matters in order, including a Bills & Spend feature that shows every payment in one place with a reminder before each is due. Users can also connect their own AI assistant to the apps.

Customers are individual consumers, and the company's revenue comes from its own products rather than client work; the company states that it does not currently take on client projects. The services run on AWS infrastructure in the EU, with data kept in the EU and handled under the GDPR.

Sparkacus is a privately held company founded in 2022 (registered on 21 December 2022) with its registered office in Pärnu, Estonia. The company describes itself as small and engineering-led, with the team reported in the 1–9 employee band.

Product: GoJars consumer apps for web, iOS and Android: local service listings, household bills and spend tracking, and connection to a user's own AI assistant.
