Products, platforms, infrastructure, security, and operations under one roof.
We build products and platforms, modernise systems, and provide fractional CTO leadership. Our work connects software, infrastructure, security, and operations, from the first architectural decisions through production and handover.
For products that cross boundaries, the seams are often where the trouble starts.
Product strategy through production delivery: web, mobile, desktop, APIs, services, payments, and the integration work between them.
Threat modelling, trust boundaries, identity and access, key custody, end-to-end encryption, application security, and controls for regulated systems.
GCP, AWS, Azure, bare metal, containers, networking, high availability, CI/CD, observability, disaster recovery, and production operations.
Understand recurring failures, reduce accidental complexity, strengthen continuity, and carry the work through deployment and handover.
High-concurrency OLTP, reporting separation, database design, migrations, integrations, and the operational discipline required around money and sensitive records.
Technology strategy, delivery ownership, team and vendor leadership, operating models, AI governance, and executive decision support.
Current working stack: Rust, Dart and Flutter, Python, TypeScript, PHP, and SQL across backend, web, mobile, desktop, and WebAssembly. Deep Linux and database work, with C, C++, Java, and Perl available where established systems require them.
Haven and Détente exercise the same disciplines Entente brings to client systems.
OpenPGP-encrypted email and MLS group messaging in one account, with user-held keys, an encrypted vault, and aliases. Ordinary email remains compatible with the wider mail network.
The work spans cryptography, cross-platform clients, mail services, storage, and production operations.
Explore Haven
A cross-vendor console for coordinating AI agents through encrypted rooms, signed operator decisions, and tasks with named owners. In active development and used by Entente's own fleet.
The work combines Rust systems engineering, cryptographic identity, durable state, and distributed coordination.
Explore DétenteClarify the business constraint, map the architecture and risks, and define the smallest credible path to an operational result.
Work close to the code, test the important boundaries, and make progress visible through running software and concrete decisions.
Deliver documentation, observability, recovery paths, and clear ownership so the system can be maintained after the engagement.
Entente brings 25 years across software engineering, infrastructure, operations, security, and technology leadership. That work includes high-concurrency transaction systems, datacentre programmes, international platform migrations, regulated environments, and two generations of encrypted communications technology.
The practice connects product decisions, security constraints, operating realities, and executive priorities. Clients get one accountable technology group across the system, with specialist depth brought to the parts that need it.
Important security claims should be open to technical inspection.
Senior technical ownership for a difficult build, a system in trouble, or a team at an inflection point.
Send a short note with the organisation, the current technology environment, and the outcome you need. Entente structures each engagement around clear ownership and access to the people doing the work.
