Allterco Robotics, better known through its flagship Shelly brand, is a Sofia-based smart-home hardware company that designs, manufactures, and sells Wi-Fi-connected relays, sensors, and smart-plug devices that have become one of the most popular prosumer home-automation product lines in Europe. Unlike cloud-locked consumer smart-home brands, Shelly devices are designed around local control, open protocols (MQTT, REST, Matter), and compatibility with open-source home-automation stacks like Home Assistant, which has earned the company a strong following among technical users and installers who do not want their lights and shutters depending on a third-party cloud. Allterco is publicly listed on the Bulgarian Stock Exchange and has expanded significantly into European and North American retail channels. It is one of the most interesting examples of European consumer hardware being built out of CEE and a useful counterpoint to the region's software-heavy tech narrative.

Imagga is a Sofia-based computer-vision company that sells image-understanding as an API: automatic tagging, categorization, adult-content moderation, face detection, color extraction, visual similarity, and custom-trained classifiers for domain-specific use cases. The product is used by stock-photo platforms, digital asset management vendors, e-commerce catalogs, and moderation teams that need to understand millions of images without staffing a full ML team internally.

Today it competes with Google Vision, AWS Rekognition, and Clarifai from a Sofia engineering base, and continues to specialize in on-premise and private-cloud deployments that US hyperscaler APIs cannot match.

Ontotext is a Sofia-based semantic-technology company that builds GraphDB, one of the leading commercial RDF-native graph databases, together with a suite of text-analysis and knowledge-graph tools used by media organizations, pharmaceutical companies, intelligence agencies, and financial institutions to turn unstructured content into structured, queryable knowledge. The BBC famously used Ontotext's semantic platform to power its 2010 World Cup and 2012 Olympics sites — one of the earliest high-profile production deployments of a knowledge graph at a major media brand — and the company has since expanded into clinical research, drug discovery, and enterprise retrieval-augmented generation (RAG) pipelines where graph-structured knowledge is paired with LLMs. Founded in 2000 as a spin-off from Sirma Group, Ontotext is a rare example of a deep, patient, deep-tech European knowledge-engineering company that predated the current AI wave and is now a load-bearing piece of several enterprise RAG stacks.
Payhawk is a Sofia-founded fintech company focused on spend management for multi-entity businesses. The platform combines corporate cards, expense controls, reimbursements, accounts payable workflows, and accounting integrations into one system designed for finance teams that need real-time visibility over company spending. That matters because expense management becomes significantly more complex once a business expands across countries, currencies, and legal entities. Payhawk's strength is in turning those fragmented workflows into a more controlled operational system that links employee spending directly to approval logic and ERP records. In the European startup ecosystem, Payhawk is notable both as a major Bulgarian success story and as an example of enterprise fintech that sells into sophisticated finance organizations rather than only SMB card use cases. It therefore sits close to travel, procurement, and financial operations infrastructure, making it a useful link between SaaS workflow tooling and regulated finance systems.

After rebranding to Quantive and acquiring additional strategy software assets, the company expanded its vision beyond OKRs into a broader strategy management category. Quantive has raised over $100 million and serves enterprise customers globally, making it one of Bulgaria's most significant B2B SaaS exports.
