Max Harlow

I’m a newsroom developer at the Financial Times. Previously I’ve worked at the Guardian, the Bureau of Investigative Journalism, and Ordnance Survey’s Geovation Hub.

I also co-run Journocoders, a group helping journalists and other people working in the media to develop technical skills for use in their reporting.


  1. Newsagent

    Automatically identify potential story leads. Lets you create autonomous bots which poll data sources and run predefined data analysis. Results are then compared to the last time the bot ran – and any additions or deletions trigger an email alert.

  2. CSV Match

    Finds matches in two spreadsheets, optionally using various fuzzy-matching algorithms. Used by organisations including the Guardian, the Times, and news agency Irin who used it to identify a company the United Nations had a contract with who was also on its own sanctions list.

  3. Reconcile

    Enrich data by doing batch lookups against various online services. For example, quickly convert a list of company names into a list of directors of those companies.

  4. Graphik

    Create simple static charts quickly – a tool for the non-technical. Can be easily customised to your organisation's house style using a simple stylesheet.

  1. Graph databases

    CIJ Summer Conference 2018London, UK

    Graph databases are incredibly useful to find connections or patterns within our data. This was a hands-on introduction to graph database Neo4j, showing examples of its use for investigative stories including the Panama and Paradise Papers, and teaching attendees how to build a graph of noteworthy individuals and match them with corporate data to see the networks involved.

  2. Finding needles in haystacks with fuzzy matching

    CIJ Summer Conference 2018London, UK

    Fuzzy matching has become an increasingly important part of data-led investigations as a way to identify connections between public figures, key people and companies that are relevant to a story. This class showed attendees how it typically fits into the investigative process, and gave a practical introduction to using the CSV Match tool I developed.
