Split Second Software Ltd, UK

Market research software.
Engineered to the millisecond.

We design and build the web and mobile platforms behind modern behavioural research, engineered for the timing precision that implicit testing demands, from respondent app to analysis dashboard.

// Who we are

The engineering arm
of a research company.

Split Second Software Ltd is a UK software company that designs and builds web and mobile applications for the market research industry. We're the sister company of Split Second Research (SSR), a behavioural research consultancy that has spent over a decade developing implicit-testing methodologies for global brands.

SSR builds the science. We build what runs it: survey and implicit-test platforms, respondent-facing apps, analysis tooling and the infrastructure underneath. Our work isn't a general web build, it ships straight into live fieldwork, where timing accuracy and data integrity aren't optional.

// What we build

Software built for research, not retrofitted for it.

Research applications have requirements most web builds never touch, response-time accuracy, respondent data handling, panel integrations, fieldwork-grade uptime. That's the default we build to.

01 / Web

Research platforms

Survey and implicit response-latency builders, respondent portals, cross-tab and analysis dashboards, admin consoles, full-stack platforms built to run live fieldwork at scale.

02 / Mobile

Respondent apps

Native and cross-platform apps for in-the-moment data capture and panel engagement, tuned to hold the timing accuracy implicit measures depend on.

03 / Data & AI

Data & AI infrastructure

Pipelines, dashboards and AI copilots that turn raw response data, timing signals and open text into structured, analysable insight, in minutes, not weeks.

// Selected work

Platforms we've designed, built and shipped.

A few of the products currently live and in use across the group.

Platform / SSR

// How we build

Our software development process.

The same disciplined process runs through everything we build. Market research is where our clients happen to be right now, SSR and Think Again Growth, not a constraint the process depends on.

Iterate, every release feeds the next sprint
  1. 01, Scope & discover

    We map requirements, users and technical constraints before writing a line of code.

  2. 02, Design

    Architecture, UX and data model decisions get made deliberately, up front, not improvised mid-build.

  3. 03, Build

    Agile sprints with the client in the room, not just a product owner. Regular demos against real scenarios, not mockups.

  4. 04, Test & QA

    Functional, load and security testing before anything reaches production, not after.

  5. 05, Ship

    Deployed and monitored under real usage, with a proper handover, not just a release note.

  6. 06, Support & iterate

    We maintain what we build and feed what we learn back into the next release.
