What Improvy OÜ does

Improvy OÜ is a privately held Estonian software company (private limited company, registry code 16377480) registered in November 2021 and headquartered at Ahtri 12, 10151 Tallinn. The company builds privacy-respecting software tools intended to help users communicate and understand information more clearly. It operates multiple consumer-facing sub-brands: Fullyst, Saylify, and InoVPN (a VPN service), distributing each through dedicated websites. Its first product — a community catalog for Minecraft servers — was discontinued prior to the current product set.

The company's technical approach is described as using AI "where useful" with an emphasis on simplicity elsewhere; disclosed proprietary technology is limited to a privacy-respecting analytics layer that avoids third-party advertising trackers and honors Global Privacy Control (GPC) browser signals. The business model is product-led growth with self-serve account creation and subscription-based recurring revenue (monthly billing), supplemented by one-time purchases; no enterprise sales motion, pricing tiers, or named customers are publicly disclosed. The company targets a horizontal base of individual and SMB users who prioritize data minimization and transparency, with no institutional investors, parent entities, or disclosed funding rounds in the available record. The company describes itself as early-stage and cash-constrained, having onboarded collaborators through equity-first and project-based arrangements rather than salaried employment.

Direct peers

• Proton (Proton AG): Proton offers ProtonMail, ProtonVPN, Proton Drive, and Proton Calendar under a unified privacy-first subscription model. Directly comparable to Improvy's combination of privacy-respecting communication tools (Fullyst, Saylify) and VPN (InoVPN).
• Surfshark: Surfshark is a consumer VPN service with subscription-based self-serve distribution. Directly comparable to InoVPN in product category, business model, and target customer segment.
• Tresorit: Tresorit is a Swiss-Hungarian end-to-end encrypted cloud storage and collaboration platform serving privacy-conscious individuals and businesses. Comparable to Improvy's privacy-respecting information/communication tools.
• Tutanota: Tutanota is an encrypted email and calendar service headquartered in Germany, with end-to-end encryption and privacy-first positioning. Comparable to Improvy's privacy-focused communication tools under the Fullyst and Saylify brands.
• Bitwarden: Bitwarden is an open-source password manager with freemium subscription pricing and end-to-end encryption. Comparable GTM (self-serve PLG, subscription) and privacy-first positioning similar to Improvy's product philosophy.

Broad incumbents

• Brave Software: Brave offers a privacy-focused browser with built-in VPN, search, and AI features. Broader and more established than Improvy but overlaps in privacy-respecting tools for consumers and PLG distribution.
• DuckDuckGo: DuckDuckGo provides privacy-focused search, browser, and email protection products with strong brand recognition. Overlaps with Improvy on the privacy-first consumer software value proposition but at significantly larger scale.

Emerging players

• Nextcloud: Nextcloud offers self-hosted productivity and collaboration tools (files, calendar, communication) with privacy as a core principle. Comparable to Improvy's communication/information tools for users seeking privacy-respecting alternatives.
