The UK Growth Companies Fundraising in Stealth Mode

Will Davis, 19 October 2022

Stealth mode startups have become a regular occurrence in the high-growth ecosystem but, as their name suggests, they’re secretive in nature and thus not widely known. Plenty of early-stage businesses also raise funding in stealth mode—around 70% of UK equity deals aren’t announced to the public, while more than three-quarters of fundraisings under £500k go unannounced. We dive into the world of stealth mode startups to find out why, and discover 10 high-growth UK companies that are raising unannounced rounds.

What is a stealth mode startup?

Typically, a stealth mode startup aims to hide everything it’s doing from the public. Common disguises include: operating under a secret name, assigning code names to new products, running a basic website that keeps a company’s employees and location a secret, or operating a strict PR policy and requiring employees to sign non-disclosure agreements (NDAs).

Other types of stealth mode startups include in-company stealth mode. This is where information is withheld internally as well as externally, usually when a company only wants to conceal one area of the business (for instance an area that’s developing a new product or functionality). Typically, this type of stealth mode is reserved for large companies who can dedicate extra resources to it, such as when Apple launches a new iPhone or iOS, for maximum public and media interest upon release.

And then there’s businesses that may or may not have a public presence but are exclusively raising investment in stealth mode. This means they’re not releasing any information about funding rounds to the press or on their website and social media.

Benefits of being a stealth mode startup

Companies operating in stealth mode are becoming increasingly popular, especially among early-stage startup founders. Here are a few of the draws to being a stealth mode startup:

IP protection
If a company needs time to work on a new project or new technology, it can better safeguard its IP (intellectual property) by operating in stealth mode.

Competition
A company’s competition has less time to respond when information isn’t made public until the last moment.

Public relations
Operating in stealth mode allows a company greater control over their PR and what prospective stakeholders see. This enables them to work on areas like strategy and product development without outside interference.

Drawbacks of being a stealth mode startup

Operating in stealth mode can still pose a problem for some startups:

Fundraising
It can be harder for startups to source funding from investors if they aren’t already an established name. Having said that, VC funds are often on the lookout for ‘the next big thing’ and usually opt to take risks on early-stage businesses that are new to the scene, where there’s potential for greater returns on investment.

Customer feedback
The process of gauging customer or subscriber feedback and finding the right product market fit can be difficult when the public is much less/not involved.

Publicity
When exiting stealth mode, companies have to work harder to attract publicity than those that have slowly built up a following throughout their development. These days, however, social media channels like Facebook, Twitter and LinkedIn mean it’s easier to generate buzz when the time is right.

Why might a company raise funding in stealth mode?

Businesses usually like to shout about new funding rounds, to showcase and celebrate their growth, and maximise joint PR opportunities with investors, as well as to attract new talent and additional investment opportunities down the line. Meanwhile, certain funding rounds will need to be publicly disclosed, as with crowdfunding. But for some startups, raising in silence may be a better option, even if they’re not operating in stealth mode.

For instance, unannounced fundraisings are often precursors to more significant events (such as a larger follow-on round or an IPO). So a company may choose to keep its initial funding round under wraps, ahead of the big announcement. A stealth round could also be a ‘down round’, in which shares are sold for a lower price than in their previous funding round. To avoid creating a negative impression of themselves, companies may keep these down rounds quiet until their valuations increase.
