Layered

All your project's evidence, in one place.

We build tools and applications that bring a project's own data together with open public data, into one live picture your team can see, question and use.

For evidence scattered across files, maps and databases.

For projects to build on past experience and lessons.

For analysis tailored to your role.

What we've built

Urban Studio screen capture

01 · Spatial analysis tool

Urban Studio

Our spatial analysis tool. It puts a project's own data on one map with open public data, such as deprivation, population, flood risk and access to services, so a team can see where needs and evidence concentrate and check them against the project's objectives.

Tall-buildings evidence base screen capture

02 · For a UK city council

Tall-buildings evidence base

Tailor-made for the client: rich 3D data collected at city scale, landmarks included, with quantitative heights and views analysis to derive policy recommendations and model different policy scenarios.

Illustration: a collection of reports tagged by theme, place and population, with a finding traced to page references in its sources

03 · Evidence synthesis

Making evaluation evidence usable

Organisations build up years of evaluations and reports that are hard to use once they are filed. We explore ways to bring that evidence together: tagging it against the questions a team is asking, comparing findings across studies and tracing each one back to its source, so lessons can shape the design of the next project. Our first prototypes worked with published evaluations.

How it works

From problem to working tool

Ways in

A defined study

A scoped piece of work, delivered through a tool you keep.

A short pilot

A few weeks with your data: a working demo and an honest assessment.

A tool inside your programme

Built with your existing team, structure and budget.

The path

  1. Bring us the problem.

    A study, a review, an evaluation, or something that doesn’t fit a template yet.

  2. We build the working tool.

    A live view of your evidence that your team works with directly, and that produces the deliverable.

  3. The tool works through your project.

    You use it to aggregate your evidence and generate outputs against your objectives, and we stay alongside, iterating it to your needs through the project cycle.

Tell us the problem and we'll shape it together

When to bring us in

Any point in the project cycle

Projects rarely arrive with a clean brief. Wherever yours stands, there is a useful way in.

  1. Before inception

    Shape the idea

    Build the theory of change together and map what is already known, and where the gaps are.

  2. Design

    Plan the evidence

    Methodology for primary data collection: interviews, surveys, web research, open data.

  3. Delivery

    Keep it live

    Monitor milestones and indicators as evidence arrives, with project files organised and searchable and dashboards kept current.

  4. Reporting

    Reach every audience

    Outputs and evidence tailored for each reader: funder report, community summary, technical annex.

  5. After close

    Document lessons

    Consolidate the evidence from the project, analyse it and assess what will be sustained, then carry the lessons forward into a structured knowledge base for your organisation.

The tool and the support fit the stage you're at. Tell us where your project is

Your project data Whatever your project holds

We build tools for people making decisions about places and programmes: councils, health and humanitarian organisations, evaluators, development teams.

Each tool brings a project's evidence into one place a team can sit in front of and question: documents, spatial data, evaluation evidence, stakeholder input, unified and readable.

Built by practitioners who've worked inside the systems we're improving. Our team brings experience from evaluating health, mental health and humanitarian programmes, community research on health and green space in London, multilateral urban development, and software for hospitals and other secure systems.

Founders

Ayesha Khalil

Co-founder

Multilateral urban development specialist (World Bank, IOM) with experience across international agencies on sustainable infrastructure initiatives. Leads strategy and partnerships.

Jonah Rudlin

Co-founder

Evaluation and research specialist (IFRC, IFC, UNDP, Mayor of London), from multi-country evaluations of mental health and humanitarian programmes to community health research in London. Leads product and research design.

Kieran Tilley

Co-founder

Software architect since 2010 across hospital software, quantitative research and secure platforms. Leads architecture, engineering and security.

2019

Origins

Layered began based on a series of ongoing conversations between the co-founders on how new technologies could be made useful in urban, social, environmental and humanitarian work.

2023

First experiments

Projects generate more information than teams can use. We began testing how new technologies could organise it, with a Greater London Authority Civic Data Innovation Challenge prototype that brought open data together to give local government and community groups a finer-grained picture of social conditions across London.

2025

Building

We built our first tools for bringing evidence together: a mapping studio that joins open spatial data with a project's own, and a prototype that makes published evaluations searchable, with every finding cited to its source.

2026

Building for projects

We now build tools for live projects that bring qualitative, quantitative and spatial evidence together: 3D evidence bases that show documents, data and maps together to inform planning decisions, and scenario models for housing growth. Every result traces back to its evidence, so it can be checked and reused.
