The Prize

The Open Up Challenge is a £5m prize fund to reward next-generation services, apps and tools that create game-changing value for UK small businesses.

We’re looking for 20 winning entries from teams anywhere in the world that will use open banking APIs – newly available from early 2018 – to transform how UK’s five million small businesses discover, access and use business critical financial products, including bank accounts, loans and overdrafts.

The challenge has two stages:

  • Stage 1 (Innovation) is aimed at ideas that deliver the most benefit to small businesses, and entries can be at an early stage or even just an idea. This stage will take place July – December 2017.
  • At Stage 2 (Market Ready) we’ll focus on entries that are market-ready. This stage will take place March – September 2018.

For more about what we’re looking for, how to apply, key dates and our eligibility criteria, see Apply.

An independent judging panel, combining a diverse range of relevant expertise, will select winning entrants and determine prize awards.

  • Cash Awards
    • In the Innovation Stage you’ll get a £50k development grant up-front, and then share in a £1m reward pot if you’re one of up to ten successful Stage 1 prize winners.
    • If you successfully enter the Market Ready Stage you’ll get a development grant from a pot of £500k for up to five teams, plus a share of a £2m pot if you are one of the final three Stage 2 prize winners.
  • Exclusive Early-Stage Access to Data
    • You’ll get access to our Data Sandbox, containing one of the largest anonymised UK banking transaction datasets ever released, and APIs aligned with the forthcoming Open Banking standard.

As part of a cohort of 20 who get development grants and access to the Open Up Data Sandbox during this stage, we’ll work with you to identify what you need and provide support where we can – whether that’s data security, data analytics or something else entirely.

  • User Researchers and UX Consultants. We’re partnering with a Service & UX Design team to carry out extensive research into how the UK’s small businesses and sole traders manage their finances – including dedicating professional user researchers and user testers to spend 1-on-1 time with every prize entrant focused on their users and product.
  • Top Legal Advice To Help You Navigate Financial Regulations. You’ll be able to talk to some of the top lawyers in finance who will help you stay compliant with data privacy legislation, data processing requirements, and regulations related to handling of financial information or brokerage of financial products – and all other legal and regulatory issues need to know about.
  • Help Growing Your Business. We’ll help you to navigate the world of UK fintech – who might invest in you, who might partner with you, which journalists will write about you – and we’ll super-charge your network with events and introductions to influencers.

Exclusive Early-Stage Access to Data and Test APIs

Our Open Up Data Sandbox provides access via API to real anonymised transaction data and other kinds of data to help you design and test your propositions.

We have a close working relationship with Open Banking Limited – the body responsible for building the final public Open Banking APIs – and the Sandbox will, so far as possible, reflect the environment awaiting you in 2018 when the APIs go live.

The Sandbox is being developed by Capco, our technical partner, with input from the fintech and data science community. Check out the information below and get in touch with your feedback (open a live chat here or email openupchallenge@nesta.org.uk).

The Sandbox will go live on 10 July 2017.

Data Available in the Sandbox

Through the Sandbox we expect you to be able to access:

  • real anonymised account and transaction data;
  • product and other reference data provided by UK banks; and
  • service quality and other supplementary data provided by Business Banking Insight and other third party data providers.

Small Business Data

  • a full list of business current accounts, including flags for promotional rates;
  • a full list of unsecured loans below £25,000 that they currently have, current interest rates paid and whether they have insurance for the accounts;
  • features of the accounts they currently hold, such as the presence of internet banking and relationship managers;
  • transaction data going back several years (number of years to be defined), including the types and amounts of each transaction, along with some information on the counterparties
  • end-of-day account balances;
  • overdraft limit changes to the account;
  • a breakdown of monthly fees that have been incurred by the account, listing the type of fee and the number of events triggering it;
  • an indicative credit rating; and
  • background information including age, location and SIC code and anoymised to a suitable level.

Bank Data

  • branch data, including: locations of fixed branches, routes of mobile branches, opening hours, services provided in each branch, types of customer eligible for using the branch, and notices of any planned closures;
  • ATM data, including locations with both postal address and coordinates, environment and access restrictions, services and languages supported, and currencies and denomination of notes available;
  • data on business current accounts offered by the bank, including: eligibility criteria, fees and services, pricing structure and promotional terms;
  • data on small business loans offered by the bank, including: eligibility criteria, fees, terms, minimum and maximum loan amounts and an indication of pricing based on tiers;
  • data on commercial credit cards offered by the bank, including: eligibility criteria, fees, types of card, features, credit limits and balance and cash advance rates.

Functional View of the Sandbox

Below is a description of the functional view of the Sandbox.

You’ll draw on three sets of APIs:

  • Reference APIs: expose reference data (ATMs, branches, personal account offerings, business account offerings, loan offerings and credit card offerings) from each bank.
  • SME APIs: expose information about the small business users you create (location, SIC code, bank accounts, transactions).
  • Portal APIs: provide the business logic for accessing the Portal Interface.

There are two ways you can interact with the Sandbox: via a Portal Interface or via an application you’ve created (you may want to get up and running with the Portal Interface before interacting with your Sandbox via your application). You’ll be able to:

  • self-register to get access to the Sandbox;
  • authenticate and retrieve an API key to call the dashboard, reference, and transaction APIs;
  • create small business user profiles linked to anonymised real world data (including bank accounts, transaction data, location, SIC code and turnover) – then log in as the user to retrieve their information;
  • log in as small business users to retrieve
  • oversee analytics on the number of endpoints you are calling;
  • view the throttling restriction on the number of calls you can make to the sandbox;
  • view interactive API documentation detailing all the endpoints and their fields;
  • view which APIs are up to date with Open Banking Limited’s latest specifications for the real-world APIs coming in 2018, which APIs are not yet aligned, and which APIs are unique to the Sandbox (we’ll add some APIs to simulate accessing data you’ll get from small business users when you go live); and
  • view information about the Open Up Challenge, including events, important dates, T&Cs, contact information and other updates.

Technical View of the Sandbox

Below is a description of the technical view of the Sandbox.

  • Users are able to register for an API key by visiting the Sandbox portal in their browser.
  • On the portal users can additionally view API documentation and dev notes.
  • Once users have created their account they can use the API key to begin consuming the APIs.
  • Each API is mapped to a distinct business functionality.
  • The service attempts to access the data via secure connections.
  • Banks upload flat files with the data to the cloud file system.
  • Anonymised small business and Business Current Account data can be loaded from flat files straight into the database.

API Specification

Below is a high-level API specification based on the Reference and SME APIs. All APIs will be RESTful.

Note that the API specification is still under development. Sign up to our mailing list to receive updates.

You’ll need to register for the Sandbox portal to get your API key.

Reference APIs

  • /atms;
  • /branches;
  • /business-current-accounts;
  • /unsecured-sme-loans; and
  • /commercial-credit-cards.

SME APIs

  • /transactions – get transactions and other information;
  • /business-current-accounts – get small businesses’ current accounts;
  • /loans – get small business loan data;
  • /creditcards – get small business credit card data; and
  • /sme/login – log in as a small business user.

Data Throttling

You’ll be able to access a maximum number of records over the 20 weeks that the sandbox will be live, and we expect this limit to be approximately 10,000 records.

The flow rate of access will be flexible, with a larger amount available earlier in the process so that you can explore what the data looks like and test your propositions.

In line with our security commitments, we’re preventing bulk downloads of data.

Data Security

The Sandbox has been designed with security in mind. Contact us (webchat or email openupchallenge@nesta.org.uk) to discuss our data security measures and your responsibilities should you be accepted onto the challenge.

  • All connections to the APIs will be encrypted (HTTPS).
  • All internet facing APIs will have both token based authentication (JWT) as well as an API key.
  • All services will run within a Virtual Private Cloud, providing network segregation and security.
  • Secure access to the servers using security groups & network access control lists.
  • Multi factor authentication will be used.
  • Data will be stored encrypted.
  • Security auditing and logging of all user actions will occur.
  • A dedicated Key Management Service will be used for the management of cryptographic keys, e.g. database encryption.
  • Two penetration (pen) tests will be completed during the build of the Sandbox.

Backend Technologies & Languages

The backend stack for the Sandbox uses latest technologies:
