    Rapid Prototyping & Proof of Concept Development

    Before a full build, a working prototype answers the questions a slide deck cannot: does the workflow make sense, is the model good enough, and will people use it.

    The cost of deciding slowly

    Most organisations lose more to slow decisions than to wrong ones. An idea enters a committee, gets a business case, gets estimated, gets scheduled — and six months later nobody has spoken to a user or seen the thing work. Rapid prototyping compresses that loop: build the smallest version that produces real evidence, put it in front of real people, and let the evidence decide.

    • Feature debates settled by seniority because no one has data
    • Business cases built on assumptions nobody has tested
    • Six-month builds that discover the core assumption was wrong in month five
    • Innovation budget spent on decks rather than working software
    • Prototypes built so throwaway that a successful one has to be restarted

    What rapid prototyping includes

    We build working prototypes in weeks, not quarters — deployed, usable and instrumented, so the output is evidence rather than an opinion. Where the prototype succeeds, the foundations are sound enough to keep building on rather than rewrite.

    • Clickable prototypes
    • Functional MVPs with real data
    • Technical feasibility spikes
    • Model quality proof-of-concepts
    • User testing support
    • Build-or-stop recommendation

    Key capabilities in detail

    Proof of concept development

    A narrow build that answers one technical or product question definitively: can this work, on this data, at this quality.

    • Single-hypothesis scoping with an explicit success threshold
    • Real data rather than curated demo samples
    • Technical feasibility assessment including cost and latency
    • A written verdict, including when the answer is no

    AI prototype development

    For AI ideas the prototype must measure quality, not just show a good example. We build the evaluation alongside the feature.

    • Labelled evaluation set built with your domain experts
    • Model and retrieval comparison against that set
    • Token cost and latency projections at expected volume
    • Clear reporting of failure modes and their frequency

    Startup and AI MVP development

    A first product that real users can sign up for and use — small in scope, complete in experience.

    • Authentication, core workflow and a usable interface
    • Payments and plan gating where the model requires it
    • Analytics and event instrumentation from day one
    • Deployed to a real domain with monitoring in place

    Design and interaction prototyping

    Clickable and coded prototypes used to resolve interaction questions before engineering effort is committed to them.

    • Interactive flows testing the riskiest interaction assumptions
    • Design-system-aligned components so work carries forward
    • Usability sessions with a small number of real users

    Path to production

    Every prototype ends with an honest recommendation: continue, pivot or stop — and if continuing, what hardening the code needs.

    • Findings write-up with evidence and recommendation
    • Technical debt register created during the build
    • Hardening plan covering tests, security and scale
    • Costed roadmap for the production version

    A typical prototype sprint

    Two to four weeks, one clearly stated hypothesis, and a demonstrable artefact at the end. Scope is fixed to what can be proven inside that window.

    • Week 1: hypothesis, success criteria, flows and data access
    • Week 2: build the core path end to end
    • Week 3: test with real users or real data volumes
    • Week 4: findings, cost estimate, and a build-or-stop call

    Use cases

    Typical situations where teams bring us in for this work.

    Testing an AI feature idea

    Prove the model can hit acceptable quality on your data before committing a roadmap quarter to it.

    Startup MVP

    Get a usable first product in front of early users and investors quickly, without building throwaway foundations.

    Internal tool pilot

    Automate one team's painful workflow and measure the time saved before rolling it out more widely.

    Vendor build-versus-buy

    Build a narrow version of the capability to establish what it really costs before signing a platform contract.

    Innovation programme delivery

    Turn a shortlist of ideas into working prototypes on a fixed cadence so the portfolio is judged on evidence.

    How NexaMarTech works

    The same delivery method every engagement follows — see our full process for more detail.

    1. 01

      Frame the question

      One or two days agreeing the single question the prototype must answer and what result would count as a yes.

    2. 02

      Scope ruthlessly

      Everything not required to answer that question is cut, and the cuts are written down so nobody relitigates them mid-build.

    3. 03

      Build in short cycles

      Weekly demos of working software. No status decks; you use the thing and react to it.

    4. 04

      Put it in front of users

      Real users, real data, instrumented so behaviour is observed rather than reported.

    5. 05

      Decide

      A written recommendation with the evidence: continue, pivot or stop, and what it would cost to productionise.

    • Reusable groundwork if the project proceeds

    Frequently asked questions

    Is the prototype code thrown away?

    Not necessarily. Where a prototype is built on a production-capable stack we carry the working parts forward; where we deliberately cut corners to move fast, we say so up front.

    What do you need from us to start?

    A named decision-maker, access to sample data, and a clearly stated question the prototype must answer.
