We work across the whole business. Pick the part that hurts.

  • AI and agents

    We build agentic systems and software factories: AI automation that runs from the product all the way through to the infrastructure. Voice and chat agents, RAG, multi-agent orchestration, and the evaluation and governance to run them safely.

  • Design

    Product and platform design, from the first sketch of the architecture to the thing running in production.

  • Development

    New builds, audits and maintenance. We run the whole project or work as part of your team.

  • Integration

    We connect and consolidate the systems you already have, so there is less to break and less to pay for.

  • Marketing

    Strategy and execution across channels, aimed at growth, public image and return on ad spend.

  • Infrastructure

    On-premise, AWS, GCP or Azure. We build what you need and keep what you have running.

  • Process engineering

    We streamline how the business runs and cut out the waste and inefficiency.

Selected work

Five products we built. We keep the names private; references are available on request.

  • VPN app and platform

    One Rust core ships native apps on five operating systems, backed by a global node network.

    • Native apps for Windows, macOS, Linux, iOS and Android from one Tauri (Rust) core
    • Native OS networking modules on each platform
    • A globally distributed, WireGuard-based node network with XTLS Reality and Vision support
    • A Stripe-integrated customer website and portal

  • Live remote-training video platform

    We built the full product experience, from the front end through the platform.

    • On-demand transcoding and CDN media streaming
    • iOS and Android apps with Chromecast casting
    • A GraphQL API powering web and mobile
    • On-demand image processing, cached to S3

  • Unified dental-practice API

    One API in front of the major practice-management systems, with data flowing both ways.

    • Bidirectional integrations with major practice-management systems
    • An embedded Raspberry Pi Compute Module sync gateway
    • Reverse tunnels from on-premise systems to the cloud

  • Direct-mail marketing SaaS platform

    Designs made in the browser come out as print-ready mail and live landing pages.

    • A Docker-on-Lambda pipeline that renders web designs to print-ready PDFs
    • Prepress handling: CMYK, USPS knockouts and indicia
    • A browser-based design editor
    • Thousands of TLS-secured custom-domain landing pages

  • Product-analytics platform

    Product usage and business metrics, modelled as a graph.

    • A Neo4j graph model of product usage
    • Data pipelines that feed the graph
    • Interactive dashboards for product usage and business metrics

How we work

Roy Hill-Percival and Kristina Kononovich founded HexTech to modernize businesses. The early years were hands-on consulting inside client teams. Since then the practice has moved toward advisory work.

  • Senior only

    Every person on an engagement is senior. The people you meet are the people who do the work.

  • Embedded and hands-on

    We work inside your team, and we take the work from design through to production.

  • Advisory

    For teams that already have the hands, we advise on strategy, architecture and technical direction.
