What RAZORlabs does

RAZORlabs is a privately-held Bulgarian software development firm founded in 2011 and headquartered in Sofia, operating a dual business model that combines custom software development services with a portfolio of proprietary consumer and business products. On the services side, the company delivers custom web platforms, mobile applications, blockchain solutions, and browser extensions for enterprise and SME clients across industries including energy/heating (Hoval Group, Toplofikacia Sofia), industrial (AURUBIS Bulgaria), retail/promotional goods (Prisma Group), government (the Bulgarian State Agency for Metrological and Technical Supervision, Municipality Rakitovo), and education (Technical University Sofia). Engagements are quote-based, often structured as multi-year contracts, and span ERP-style systems, e-commerce platforms, IoT monitoring, and decentralized applications.

On the products side, RAZORlabs builds and maintains a portfolio of self-serve software distributed primarily through browser extension stores and own websites: Night Eye (paid dark-mode browser extension with 500,000+ daily active users), BlockZilla (ad/promoted-content blocker), Drive Password (Google Workspace-native password manager), Visual Debug (visual feedback tool for client-developer communication), Horenso (asynchronous team information collection, distributed as Slack and Discord apps), and Movemar (field marketing and merchandising platform). The proprietary technology stack spans Laravel, Python, ReactJS, Solidity for blockchain/smart contracts, Flutter for mobile, and Rust/Go/Node.js/TypeScript for the Cudos blockchain network server infrastructure.

The company monetizes through professional services project contracts, paid browser extension downloads, and subscription/freemium SaaS products, and claims 87 clients served, 860,458 active users of its software, and a global footprint spanning 130 countries and 5 continents. RAZORlabs is bootstrapped with no disclosed external funding, runs an intern/education pipeline through Technical University Sofia, and has demonstrated exit capability via the 2022 sale of Relanote to a US-based acquirer.

Direct peers

• Infinum: Croatian-headquartered software agency of comparable size with a dual model of client services and proprietary products. Closest geographic and operating-model analog to RAZORlabs.
• Dark Reader: Open-source dark-mode browser extension and the most direct free competitor to Night Eye. Same product category, target user, and browser-distribution channel.
• uBlock Origin: Open-source ad/content blocker and direct competitor to BlockZilla across Chrome, Firefox and Edge. Competes on the same sponsored-content-hiding use case.
• Bitwarden: Cross-platform password manager with freemium/premium tiers, directly comparable to Drive Password in product category, target user, and Google Drive-adjacent positioning.
• Basecamp (37signals): Boutique software firm that develops and sells its own products (Basecamp, HEY) while maintaining a small, profitable team. Closest model analog for RAZORlabs' services-plus-own-IP approach.
• LimeChain: Bulgarian/European blockchain development firm (a known RAZORlabs partner via Cudos). Most direct peer for its enterprise blockchain services line of business.

Broad incumbents

• BairesDev: Large nearshore software development firm serving enterprise and SMB clients with custom solutions. Comparable services offering, though at materially greater scale.
• 1Password: Established password manager with business and consumer plans; broad incumbent against which Drive Password competes for Google Workspace users and SMBs.
• Automattic: Company behind WordPress that combines open-source platform development with commercial products and services. Comparable dual services-and-products model, though at much larger scale.

Emerging players

• Toptal: Freelance talent marketplace for software engineers. Represents an alternative model for monetizing engineering capacity that competes for the same enterprise custom-development budget.
