Bitstamp
Bitstamp is one of the oldest continuously operating cryptocurrency exchanges in the world, founded in 2011 in Ljubljana by Nejc Kodrič and Damijan Merlak as a European alternative to Mt. Gox, and the first crypto exchange to obtain an EU-wide payment-institution license via Luxembourg. The exchange became a workhorse for professional traders and corporate treasuries in the early bitcoin era because of its deep order books, straightforward fiat rails, and relatively boring, compliance-first posture compared to more speculative venues. Bitstamp has moved its headquarters structure across Luxembourg, London, and the US over the years but its Slovenian origin and engineering roots remain, and in 2024 Robinhood announced a USD 200 million acquisition to use Bitstamp as the backbone of its European and institutional crypto business — a validating exit that puts Slovenia on the map for globally significant crypto infrastructure. For the directory, Bitstamp is the canonical Slovenian fintech deep-tech story.

Celtra
Celtra is a Slovenian adtech company focused on creative automation for digital marketing teams. Its software helps global brands and agencies produce, adapt, and distribute large volumes of campaign assets across formats, channels, languages, and audience variants without forcing design teams to recreate each asset manually. That capability matters because modern digital advertising requires massive variation in size, copy, locale, and targeting logic, and manual production quickly becomes a bottleneck. Celtra therefore sits in a high-value operational layer between creative strategy and campaign execution, helping marketing teams scale output while preserving consistency. In the European startup ecosystem, it is a strong example of B2B software built around workflow automation for brand and media teams rather than around direct media buying. It also connects naturally to localization and consumer-growth companies already in the directory, since multi-market campaigns depend heavily on structured creative production at scale.

DDD Invoices
DDD Invoices is a Ljubljana-based API-first compliance platform that lets software vendors, ERPs, accounting tools, and marketplaces emit fully compliant e-invoices and fiscal reports across dozens of jurisdictions through a single integration. The product abstracts country-specific formats (Peppol BIS, FatturaPA, UBL, FacturX, SAF-T, FA_VAT and others), government clearance flows, digital signing requirements, and archival rules, so the customer team does not have to track the dozens of overlapping mandates that the EU's VAT in the Digital Age (ViDA) agenda is phasing in. The company's bet is that mandatory structured e-invoicing across the EU between 2026 and 2030 turns what used to be a back-office nice-to-have into a default requirement, and that most vertical SaaS builders would rather buy than build that compliance layer. It is one of the clearest examples of a Slovenian B2B SaaS built directly against upcoming European regulation.

Elaphe Propulsion Technologies

Elaphe received €7 million from the Slovenian government in 2021 and has supplied its technology to automotive partners globally, including Aptera. It is headquartered at Technology Park Ljubljana.

Katalist
Katalist is a Slovenian-founded generative-AI startup building an end-to-end pre-production workspace for video: writers and directors can import or draft a script, let the system break it down into beats, shots, and storyboards, generate consistent character and location renders, and iterate on the look of every scene before a single frame is filmed. The key differentiator is character- and setting-consistency across shots — the hard problem that plagues early image and video models — which Katalist addresses with reference-conditioning and scene graphs rather than naive prompt chaining. The target users are in-house content teams at brands, boutique production studios, and advertising agencies that have to produce far more video than their traditional pipelines can absorb, and that need a visual ideation layer that survives client feedback cycles. The company graduated from 500 Global's Eurasia program and is one of the more interesting European pre-production tools competing with the LTX Studio / Showrunner generation of US AI-film products.

Outfit7
Outfit7 is the Slovenian-born mobile entertainment studio behind the Talking Tom and Friends franchise, which has become one of the most downloaded mobile IPs in the world and a textbook example of a European consumer software company achieving escape velocity into the US and Asian markets without relocating its engineering base out of Ljubljana. Founded in 2009 by Samo and Iza Login, the studio combined a viral AR-era animal avatar concept with disciplined live-ops, mobile advertising, and cross-promotion to drive billions of downloads, and in 2017 sold to China's Zhejiang Jinke Entertainment in one of the largest cash exits ever achieved by a Slovenian tech company. Today Outfit7 remains the anchor of Slovenia's consumer gaming cluster, running the Talking Tom & Friends universe across games, TV series, and licensed merchandise, and continuing to ship new free-to-play titles from its Ljubljana, Limassol, and London offices.
