How should deep tech companies adapt their communications strategies to encourage domestic investment?
Throughout 2026 we’ve seen government spending decisions, parliamentary bills and industry naval gazing all hung up on the question: who controls the infrastructure the UK depends on for its security, prosperity and resilience, and what happens if that control shifts? Thanks to a unique blend of geopolitical forces, and previous opportunities missed, technological sovereignty has become a defining anxiety of our era.
Among the soul-searching, there is an opportunity for UK deep tech companies here. As the UK government battles to turn the tide, companies have the chance to capitalise on the new attention to highlight the importance of their innovations and secure domestic support to scale. The question is how...
The UK's deep tech challenge
The UK certainly doesn't lack innovation, it has world-leading universities, exceptional founders, and category-defining companies in quantum, robotics, semiconductors and geospatial technology. What it struggles with is converting invention to industrial scale. Early capital is accessible; scale-up capital to commercialise deep tech domestically has not been. Or at least, not as accessible as it needs to be, in the volumes required.
The result? Ultimately UK-born companies have looked overseas for growth capital or become acquisition targets. Quantum Motion and Darktrace are recent reminders that inventing world-class technology and growing it as a domestically-owned success story are two very different things.
Government action stations
Government funding and policy has certainly been spurned into action to tackle the sovereignty issue. A £500 million Sovereign AI Fund launched in April. £400 million has been committed to domestic AI chips and compute infrastructure. In July, the Government Digital Service published its Cloud Challenge Book, an attempt to coordinate the public sector's fragmented cloud demand and reduce dependency on a handful of overseas hyperscalers. A cross-party amendment to the Cyber Security and Resilience Bill now calls for a formal digital sovereignty strategy within 12 months. And we’re seeing new capital solutions such as the UK Scale-up Fund, the British Business Bank's vehicle for mobilising £1bn of pension capital to back the next generation of high-growth British science and technology companies.
Companies will be wondering how they can get ‘in on the action’ and further encourage UK funding for deep tech.
The missing piece
So much of the sovereignty conversation talks about infrastructure changes, but there is little about the more human side of things – like the role of adoption and education – in retaining our most important technologies.
A quantum computer in a lab may strengthen national capability just by existing. But technologies can only become strategic assets considered worth protecting when customers buy them, investors back them, policymakers understand them well enough to support them, and talented people choose to build careers around them.
That requires trust. It requires understanding. And building both, at scale, across audiences that range from Whitehall to venture capital to the general public (especially if their pensions are funding it), is a communications challenge as much as a technological one.
Where communications can support sovereignty
A company can have a genuinely differentiated, sovereign technology but if it can't clearly explain why it matters, which problem it solves, and why the UK benefits from it staying here, it will struggle to hold the attention of the investors, customers and policymakers who influence whether it scales domestically or must look elsewhere. And if the average person doesn’t understand its significance, then any government will struggle to get a mandate to aggressively support home-grown technology.
For tech companies looking to grow their businesses here, and benefit from a new wave of public interest and support, there’s a few communications approaches they can employ to increase their chances:
1. Show what’s at stake: Don't lead with what the technology does technically but with what happens to the UK if it leaves. All content should point to why a technology staying British matters to someone who isn't a specialist.
2. Invest in comms early: Many deep tech founders only invest in comms once they need to raise growth capital or attract government attention, by which time it can be too late. Considering comms capability (whether in-house or agency) at seed/Series A stage means the story is built alongside the technology, not retrofitted onto it, and builds credibility in time for when the company really needs it.
3. Know your audiences, and tailor accordingly: A policymaker needs to understand a technology in terms of potential risk and potential economic upside to justify any intervention, while the general public will be more interested in its impact on jobs, and quality of life. Only by tailoring messaging to each audience will companies get the right attention.
4. Foreground adoption over investment: Funding announcements are great proof points, but they’re not evidence of a technology being a strategic asset. Partnerships and customer stories showcase real-world adoption, and something tangible beyond investor belief.
5. Prioritise thought leadership: Companies that are visible in the media talking about how their area of innovation - whether quantum, materials, cleantech - will benefit the British economy and support British industry to thrive, will excite investors and encourage government to champion them. What's more, for businesses that are still proving their technology, thought leadership signals trust and expertise. In the absence of real-world data, this is a good proxy for value, potential, and trustworthiness in the eyes of investors, customers and government.
The ingredients for UK technology sovereignty are there: world-class research, entrepreneurial talent, and now serious capital and policy protections. What's still missing is the narrative that makes the case, beyond specialist audiences, for why these technologies matter and why keeping them British is worth the investment. If companies can get their comms right, they can help unlock the support needed to grow here, capitalise on the growing interest in sovereign capabilities and, hopefully, be the next big British success story.
