Symless Inc.

What Symless Inc. does

Symless Inc. is a privately-held UK software company (legally Symless Limited, registration 08066283, with an Isle of Man branch) that develops and sells Synergy, a software-based keyboard and mouse sharing utility used to control multiple computers from a single input device across Windows, macOS, Linux, and Raspberry Pi OS. The product operates over a local area network using HID emulation and protocol-based communication between machines, with features including TLS/SSL encryption, automatic key swapping, customizable hotkeys, and clipboard sharing. The commercial stack is built on Deskflow, a GPLv2 open-source upstream project maintained by the Symless team, and includes two parallel product lines: Synergy 1 (mature, enterprise-focused, with centralized policy controls and legacy OS support) and Synergy 3 (current flagship with a rebuilt Qt-based GUI, auto-config, and auto-discovery).

The company sells through a hybrid model: a self-serve, product-led motion offering one-time perpetual personal licenses (Synergy 3 Lite $15, Plus $19, Max $29) directly on symless.com with a 30-day money-back guarantee, and an enterprise field-sales motion for business customers with annual subscriptions (Single User $75, Teams $100/seat/year minimum 2 seats, Enterprise Managed custom) that include procurement support, dedicated account management, and policy-based configuration. Customer segments span individual power users (developers, streamers, home-lab enthusiasts), businesses and enterprises, educational institutions, and government/public-safety organizations, with cited adoption across 26% of Fortune 1000 companies including Google, Amazon, Apple, Intel, Nvidia, Cisco, GE, and HP, plus institutional deployments at Imperial College London, Full Sail University, and Cherokee County 911.

The company is bootstrapped and founder-led (Nick Bolton), with a lean 1-10 person team, no disclosed outside funding, and an active open-source posture including Deskflow stewardship and financial support for KDE e.V. and the GNOME Foundation. It is mid-transition on two fronts: a rebranding from Symless to Synergy to align corporate and product identity, and an EULA evolution clarifying personal-versus-business licensing definitions. Revenue is not publicly disclosed.

Core offering

Symless develops and sells Synergy, a software-based KVM (keyboard-video-mouse) solution that lets a single keyboard and mouse control multiple Windows, macOS, Linux, and Raspberry Pi computers over a local network. The product uses HID emulation to switch control between machines when the mouse crosses a screen edge, with shared clipboard, cross-platform key swapping, hotkey configuration, and optional TLS/SSL encryption. The company sells personal perpetual licenses (Synergy 3 Lite, Plus, Max) and annual business subscriptions (Single User, Teams, Enterprise Managed) for organizational deployments.

Product overview

Symless Inc. offers Synergy, a software KVM (keyboard-video-mouse) solution that enables users to control multiple computers with a single keyboard and mouse. The product portfolio includes two main commercial products: Synergy 1 (mature, enterprise-focused, with features like centralized policy-based configuration and legacy OS support) and Synergy 3 (current flagship with a rebuilt GUI and auto-discovery). Synergy 3 is offered in three personal tiers (Lite at $15, Plus at $19, Max at $29) as one-time purchases, plus three Business/Enterprise tiers for organizations. All products are built on Deskflow, an open-source upstream project maintained by the Synergy team, with most of Synergy 3 being open source (GPLv2) while commercial support and updates are provided. The company also supports the open-source ecosystem through contributions to KDE, GNOME, and individual developers.

Expansion highlights5 records

Direct peers

• ShareMouse: ShareMouse is a direct software KVM competitor offering keyboard and mouse sharing across Windows, macOS, and Linux. It targets the same multi-computer productivity use case as Synergy with similar pricing and feature overlap, making it the closest head-to-head rival.
• Stardock Multiplicity: Stardock's Multiplicity is a software KVM product enabling one keyboard/mouse across multiple PCs, directly competing with Synergy in the same niche. Stardock is a long-established Windows utility publisher, providing a relevant competitive benchmark.
• Barrier (open source): Barrier is an open-source fork of Synergy 1's codebase that provides essentially identical keyboard/mouse sharing functionality for free. It is the most direct free alternative and represents the open-source commoditization pressure on Synergy.
• Input Leap: Input Leap is a community-maintained fork of Barrier, continuing development of the open-source Synergy lineage. It offers the same core functionality and competes directly for cost-sensitive users who would otherwise consider paid Synergy licenses.

Broad incumbents

• Microsoft Mouse Without Borders (PowerToys): Microsoft's free Mouse Without Borders utility, now distributed via PowerToys, provides keyboard/mouse sharing across Windows PCs. As a free tool from a major OS vendor, it is a powerful incumbent threat specifically for Windows-only Synergy users.
• Logitech Flow / Logitech Options+: Logitech Flow (via Options+) provides seamless keyboard/mouse switching across up to three computers when paired with compatible Logitech hardware. It is a leading cross-vendor competitor, especially in consumer and prosumer segments, with the advantage of integrated hardware.
• Apple Universal Control: Apple's native Universal Control feature allows a single keyboard/mouse/trackpad to move across Mac and iPad devices. As a free, OS-bundled solution, it directly substitutes Synergy for the Apple ecosystem segment.
• ATEN International: ATEN is a major hardware KVM switch vendor serving enterprise and industrial customers. It represents the traditional hardware alternative to Synergy's software KVM approach, particularly relevant for enterprise buyers evaluating Synergy against hardware KVM solutions.
• Raritan (Legrand): Raritan, a Legrand brand, is a leading enterprise hardware KVM-over-IP vendor serving data centers and mission-critical environments. It competes with Synergy's enterprise tier for high-stakes multi-computer control scenarios.

Others

• Splashtop: Splashtop provides remote desktop and cross-device access software that overlaps with Synergy's clipboard and multi-computer use cases at the edges. It is a broader remote-access platform, complementary to rather than directly substitutive of Synergy, but competes for adjacent IT budget.
