Sonder Digital

Sonder Digital is a mobile and software development company with offices in Vilnius, Lithuania; Warsaw, Poland; and Detroit, Michigan. The team traces its roots to telecom and engineering backgrounds—early work centered on fleet management and transport monitoring systems before pivoting to mobile development during the smartphone era. Leadership includes CEO Andzej Lankut and CFO Svetlana Lankut. The company earned a Clutch Leader Award (November 2019) and was recognized by GoodFirms as a Best Business Solutions Provider.

The firm's core work spans mobile app development, custom software, web development, and IT consulting. Early experience came from programming GSM monitoring terminals and devices with cellular connections, then evolved into iOS and Android development after team leaders received professional training in both platforms. The company has worked on projects ranging from e-commerce apps to medical applications with complex architecture.

Services and capabilities

Sonder Digital's service menu includes startup development, custom software development for various business niches (named examples: medical institutions and manufacturing), digital design, web development, mobile development, and IT consulting. The About page states the firm helps with "consultations and marketing tools to the final product," suggesting end-to-end engagement from strategy through launch.

Their portfolio shows real delivery: GetBetter (a social network for people with chronic diseases, developed since 2016 and still supported), Proxima (a social philanthropy platform for donors and funds), Sport Charger (training app for a sports school), Movamba (taxi service management system), Assistant (voice assistant development using AI), I Drive Analytics (road emergency situation analysis), School (education app for students and teachers), and Bombishka (discount and promotional code app).

Clients from testimonials include SpeakToIt (USA), which worked with Sonder Digital since 2011 on two communication apps and an Assistant client; Ringo Solutions (Poland); Massive Infinity (Singapore); PIGU (Lithuania, for QA on web and mobile apps); and a top shopping app in Asia. GetBetter's founder, Stanislav Sazhin, describes Sonder Digital as a "strong and flexible partner."

How they work

The firm operates as a full-service partner. Client feedback emphasizes communication and project management: Marcus, a Swedish startup founder, noted they "developed my app from scratch (incl. development of an architecture and a design)" and provided "excellent communication skills." The PIGU engagement involved testing and QA, with the team flagging critical issues and offering proactive suggestions for improvement. The company operates across time zones (offices span Lithuania, Poland, and the US) and is experienced with remote partnerships, as evidenced by Jaunius Danielius's comment that they performed "excellently...by working remotely."
