Data Stack Conf is a single-day, community-organised technical conference held at the Inter Expo Center in Sofia, Bulgaria, on 13 October 2026. The programme covers modern data platforms, databases, streaming systems, analytics, observability, AI data infrastructure, cloud-native architectures, and distributed systems. It is built for engineers who design, build, and operate data platforms at scale, and runs alongside two sister events, Full Stack Conf and AI Stack Conf.
Data Stack Conf is a community-run technical conference dedicated to modern data engineering. The single-day 2026 edition takes place on 13 October at the Inter Expo Center in Sofia, Bulgaria. The programme addresses the systems engineers use to move, store, process, and observe data: data platforms, databases, streaming systems, analytics platforms, observability stacks, AI data infrastructure, cloud-native architectures, and distributed systems.
The event targets practitioners rather than business buyers. Its stated audience is engineers who build and operate modern data platforms at scale, which places it at the implementation end of the data conference spectrum. It is organised by a community team and forms part of a three-event family alongside Full Stack Conf and AI Stack Conf.
The 2026 edition of Data Stack Conf is a single-day, in-person event held on 13 October 2026 at the Inter Expo Center in Sofia. No online or hybrid attendance option is disclosed by the organiser at the time of verification.
The Call for Papers is open. As a result, the speaker roster and the detailed session schedule are not yet published. Prospective speakers can submit proposals via the official website at https://datastackconf.com/.
Pricing has been announced only in part. A Super Early Bird ticket was offered at EUR 50 and expired on 1 June 2026. Further ticket tiers and prices had not been published by the organiser at the time of verification and should be confirmed directly on the official site.
Data Stack Conf occupies the practitioner, community-conference end of the data calendar rather than the vendor-summit model. Its single-venue, single-day structure and community organisation distinguish it from large commercial expos. The Sofia location positions it within the Central and Eastern European technical conference circuit, accessible to engineers across the region and beyond.
The event is one of three sister conferences run by the same community team. Full Stack Conf addresses software engineering more broadly, and AI Stack Conf covers applied AI, while Data Stack Conf concentrates on the data platform layer. This structure lets the organisers keep each event focused on a defined practitioner audience rather than blending tracks into a single broad programme.
The organiser describes the audience as engineers who build and operate modern data platforms at scale. Based on the programme themes, the typical attendee profile includes:
The event is not designed for non-technical business executives or for attendees seeking strategy and governance overviews. Its content assumes a working knowledge of data systems engineering.
The 2026 themes published by the organiser span the modern data platform stack:
The detailed session schedule depends on the outcome of the open Call for Papers and was not published at the time of verification.
Data Stack Conf is a single-day community technical conference on modern data engineering, held in Sofia, Bulgaria. It is organised by a community team, with Radoslav Stanoev, Nayden Gochev, and Velichka Vodenicharova named among the organisers. The general contact address is info@datastackconf.com. The event is one of three sister conferences alongside Full Stack Conf and AI Stack Conf.
The event is not designed for non-technical business executives seeking data strategy or governance overviews, nor is it an investor forum or startup showcase. Attendees without a working knowledge of data platforms, distributed systems, or data engineering will find most sessions difficult to follow.
The three conferences are run by the same community team and address adjacent technical audiences. Full Stack Conf covers software engineering broadly, AI Stack Conf covers applied AI, and Data Stack Conf focuses specifically on the data platform layer: platforms, databases, streaming, analytics, observability, and data infrastructure.
Yes. The Call for Papers for the 2026 edition is open. Prospective speakers can submit proposals through the official website at https://datastackconf.com/. Because the CFP is open, the speaker roster and detailed schedule are not yet confirmed.
The 2026 edition is held at the Inter Expo Center in Sofia, Bulgaria. The Inter Expo Center is one of the largest exhibition and conference venues in Sofia, used for trade fairs, conferences, and corporate events.
