Tessares

What Tessares does

Tessares is a Belgium-based private software company founded in 2015 and headquartered in Louvain-la-Neuve, with an employee count in the 11–50 range. The company develops Multi-Path TCP (MPTCP) hybrid internet access software that enables telecommunications operators to aggregate multiple network connections — 4G, 5G, and fixed broadband — into a single, higher-reliability link. The product is positioned as interoperable and adaptable, specifically addressing the fragmentation that arises from differing equipment-vendor interpretations of telecom standards.

The firm's commercial go-to-market relies on a core channel partnership with Wavenet, a Belgian telecom services company with more than 25 years' experience, which deploys and maintains Tessares solutions for major European operators including Nokia, Orange, SFR, VOO, and Telia. Direct customer evidence is concentrated within the telecommunications-operator segment, with no disclosed diversification into adjacent verticals. Funding history is modest and EU-anchored: a 2015 founding investment by Proximus Group, a ~$3.7M round in 2018 from Proximus, S.R.I.W., and Vives Louvain Technology Fund, an ~$86K EISMEA grant in 2018, and ~$1.34M from the European Innovation Council in 2019.

Tessares' competitive posture rests on proprietary MPTCP protocol engineering rooted in academic research at UCLouvain (founders Olivier Bonaventure, Denis Périquet, and Gregory Detal). Pricing, contract structures, and revenue figures are not publicly disclosed, and the company has not announced funding or expansion activity in the publicly available data beyond 2019.

Core offering

Tessares develops and supplies a hybrid internet access software solution based on Multi-Path TCP (MPTCP) technology. The solution enables telecommunications operators to combine multiple network connections (such as 4G, 5G, and fixed broadband) into a single aggregated link, improving reliability and performance for end users while remaining interoperable across equipment vendors.

Product overview

Tessares provides a hybrid internet access solution based on MPTCP (Multi-Path TCP) technology. This solution enables telecom operators to combine multiple network paths (such as 4G, 5G, and traditional wired connections) to deliver improved connectivity performance and reliability. Wavenet serves as a deployment and maintenance partner for the Tessares solution, supporting major European telecom operators.

Recent moves6 records

Expansion highlights3 records

Emerging players

• Benu Networks: Benu Networks delivers software-based broadband edge and multi-access solutions for service providers, including Wi-Fi/cellular aggregation. Its multi-access approach is conceptually similar to Tessares' hybrid 4G/5G/fixed broadband aggregation.
• Casa Systems: Casa Systems provides broadband and mobile edge solutions to telecom operators, including vCCAP, fixed-wireless access, and 5G core. It competes with Tessares in operator edge connectivity, though with a hardware-software hybrid rather than pure-software MPTCP.

Direct peers

• Citrix (Citrix SD-WAN): Citrix SD-WAN is a software-based hybrid WAN solution sold to operators and large enterprises. It directly overlaps with Tessares' value proposition of combining multiple underlays into a reliable, high-performance connection.
• Versa Networks: Versa Networks is a pure-play SD-WAN/SSE vendor offering software-defined hybrid WAN with multi-path capabilities. Its software-only delivery model and operator focus make it a direct comparable to Tessares' MPTCP hybrid access solution.

Broad incumbents

• HPE Aruba Networking (Silver Peak): HPE Aruba's Silver Peak-based SD-WAN provides edge-to-cloud hybrid connectivity for branch and multi-site enterprises. It competes with Tessares in the hybrid-WAN category but as part of HPE's broader enterprise networking portfolio.
• VMware by Broadcom (VeloCloud SD-WAN): VeloCloud is one of the leading SD-WAN platforms, used by operators and large enterprises to deliver hybrid connectivity over multiple underlays. It is functionally adjacent to Tessares' MPTCP hybrid access, though VMware/Broadcom serves a much broader SD-WAN market rather than operator-specific hybrid access.
• Cisco (Viptela SD-WAN): Cisco offers Viptela-based SD-WAN solutions widely deployed by telecom operators and enterprises for hybrid WAN connectivity. Like Tessares, Cisco enables hybrid WAN/multi-path connectivity, but at much larger scale and as part of a broad networking portfolio rather than a focused hybrid-access product.
• Ericsson: Ericsson offers operator-grade network software and services that intersect with Tessares' hybrid-access proposition, particularly around 5G and fixed-wireless convergence. Like Nokia, it is a potential partner, competitor, or acquirer for Tessares.
• Fortinet (FortiGate SD-WAN): Fortinet integrates SD-WAN into its FortiGate security platform, widely used by enterprises and service providers for hybrid connectivity. It overlaps with Tessares on hybrid WAN delivery but pairs it with a large security franchise.
• Nokia (NetGuard / AVA): Nokia is both a Tessares customer and a major telecom vendor with NFV, vCPE, and network-services software that addresses hybrid-access use cases. It represents the largest incumbent that could partner with, compete with, or ultimately absorb Tessares-style capabilities.
