Rocket List 2019

A curated list of the best fast-growing companies in London to work for. Built for job-seekers. Updated quarterly.

The best fast-growing companies in London to work for

You'll learn more if you're working somewhere that's growing fast. As a candidate, it's difficult to spot the best companies from the outside (every company has a great website and good press). We've spent weeks researching the best companies to help you focus your job search.

Unlike other 'top startup' lists, our focus is on giving you more information and insight (for example, we include our take on the market and have found examples of people being promoted within the company). This list isn't exhaustive, we know there are great companies not included.

Who are we?

We are building the best way to search for jobs at fast growing companies. Visit our website to be the first to try it.

Mission

Bud builds the products, tools and services that transform personal finances into something to engage with, rather than avoid. Their mission is to make money simpler for everyone by building a layer of thoughtful financial confidence into the every day.

Our take on the market

  • Fintech innovation in the UK is being pushed further by the Open Banking standards (requiring institutions to provide APIs to access your financial data)
  • As a result, it has never been easier for companies to interact with your financial world
  • It's inevitable that more and more companies will want to connect and speak to each other
  • The technologies and partnerships to build this financial layer are complex, meaning the winning businesses will be defensible

Why are they doing so well?

  • Bud was quick to realise the need for a new financial layer, preparing for Open Banking (and PSD2, the European standard) long before it was launched
  • The product has great design, making it easy for new products (whether it's established companies or small prototypes) to integrate
  • The team built out the biggest use cases first to ensure they were giving potential customers value early on

Founders

Data Scientist at Wonga, one of the companies that pioneered the smart use of data for loan decisions. Joined Entrepreneur First where Cleo was formed.

Mission

Cleo's goal is to be the go-to place to manage your relationship with money - a Google-sized company, forcing banks to compete across products and services by putting the consumer first.

Our take on the market

  • Consumer-facing fintechs are exploding in the UK
  • People are not satisfied with the products being offered by traditional banks, who have proven slow to react to the needs of more demanding consumers
  • The traditional banking space is being reinvented, but there are other apps trying more unconventional angles to help people get more out of their money

Why are they doing so well?

  • Cleo was one of the first companies to offer millenials a unique way of getting more out of their money
  • They were one of the first companies to make great use of chatbots that sit within Facebook's messenger app
  • Their mobile-first approach and Gen Z user base has given them strong virality, enabling them to grow to over 1 million users
  • They have taken a lean approach, deciding not to become a bank in their own right. This has enabled them to grow domestically and expand internationally without much friction (there are far fewer regulatory hurdles when you're not a bank).

Founders

Studied mechanical engineering at Warwick, worked in Metal Additive Manufacture research, and co-founded the company with Chris at Entrepreneur First

Studied computer science at Imperial, and worked at Google before joining Entrepreneur First and meeting Theo

Mission

More than £100Bn worth of components are produced using CNC Machines every year, but today the process is slow, costly and heavily reliant on human input. We are developing technology that fully automates CNC manufacturing, hugely reducing the cost of parts while boosting quality and speed of delivery.

By developing fully autonomous, fully flexible factories with this technology at their core, CloudNC is working to make the dream of automatic manufacture a reality.

Our take on the market

  • Industrial production hasn't seen that many breakthrough innovations in the past decades (after centuries of innovation)
  • The introduction of AI into machinery is enabling new levels of reliability, ease and cost. Atomico are calling it industry 4.0
  • Manufacturing is a huge market, but is also going through shifts as we move away from mass production towards a focus on innovative-design and personalisation. The technology that enables cheaper manufacturing will be central to this shift

Why are they doing so well?

  • CloudNC are tackling a big problem others are shying away from
  • The articulation of the benefits is very clear and provides a huge step change: parts should take days to produce, not weeks
  • The founders are both engineers and this puts them in a strong position to make the most of the opportunity

Our methodology

It's really tricky to pick a manageable number of companies to dig deep into, so we relied on three areas to reach our shortlist

  1. Plenty of jobs available. Given our list is for job-seekers, we looked closely at the number of roles available over recent months. We only want to show you the companies that are hiring in numbers. There were some great companies (based on other criteria) that we excluded because they had <5 roles open
  2. High growth. It's hard to find a metric for growth to compare all companies. We considered the last two fundraises (£-value and date) as this data is readily available
  3. Strong investors. We know that not all great companies have great investors, but a strong investor (e.g. Index Ventures, who backed Facebook) is a useful signal that the company is going places. The investor will have done their homework to test the market, the business potential, the management team’s capabilities, etc
