Overview

ExecMode is CodeWeavers’ bespoke technical consulting arm, designed to help organizations tackle exceptionally difficult technical problems. Unlike PortJump, ExecMode does not rely on Wine or Windows compatibility layers. Instead, the service delivers custom open‑source solutions—such as upstreaming patches, building integrations, optimizing tools, and supporting mission‑critical software projects—for enterprises and large clients. ExecMode focuses on partnerships where internal constraints or legal/regulatory barriers prevent typical development approaches, bringing CodeWeavers’ engineering expertise to bear through a phased process that begins with a free consultation and can culminate in full implementation

Features and Capabilities

• Initial Consultation: a free, one‑hour session to define the technical challenge, assess feasibility, and determine success criteria, scope, timeline, and budget.
• Discovery Phase: fixed‑fee engagement to research and detail the problem space, assess feasibility, and map potential open‑source solutions. A report is delivered regardless of outcome.
• Statement of Work: a formal plan defining requirements, deliverables, timeline, and cost where ExecMode confirms capability to solve your challenge.
• Implementation: full technical delivery—from upstream patching to custom open‑source code development and system integration—tailored to client needs.
• Open‑Source Upstreaming: ability to deliver patches and enhancements to open-source projects on clients’ behalf—even when clients face legal or procedural barriers to direct contributions
• Complex Challenge Focus: ideal for enterprise‑level, hardware‑level, simulation, robotics, data‑processing, or performance‑critical systems where off‑the‑shelf solutions fall short.
• Proven Technical Track Record: CodeWeavers engineers have solved tough challenges, such as optimizing robotic simulation performance and reducing mission-critical process runtimes in highly constrained environments
