Deep Tech Funding – Seed to Series A Support

Seed to Series A deep tech funding at a glance

Deep tech startups between Seed and Series A now need both strong ARR and a smart capital stack. FI Group UK helps you combine R&D tax relief, grants and other non dilutive funding so you extend runway, reduce dilution and hit investor milestones faster.

From AI infrastructure and quantum to MedTech, climate and advanced materials, the journey from Seed to Series A is longer, riskier and more capital intensive than classic SaaS. The founders and technical leaders who could write grants and R&D claims are the same people needed on pilots, integration and core R&D. Treating specialist funding support as a strategic investment, not a cost to avoid, is now a board level decision.

Why non dilutive capital matters between Seed and Series A
Why non dilutive capital matters between Seed and Series A

Non dilutive capital lets deep tech companies extend runway and accelerate R&D without giving up additional equity, which is critical between Seed and Series A where traction expectations have risen but risk and burn remain high.

Across the UK and Europe, early stage investors increasingly expect founders to have explored available non dilutive sources before asking for more equity. Grants and R&D tax relief are now standard parts of the funding mix for pre seed, seed and Series A companies, particularly those investing heavily in research and development.

Key benefits for deep tech teams include:

  • Runway extension without additional equity dilution
  • Proof of capital efficiency to current and future investors
  • De risking of core R&D, since public funding supports high risk work
  • Stronger negotiating position at Series A, with more time to hit milestones

Why non dilutive capital matters between Seed and Series A
Dilutive vs non dilutive funding at Seed to Series A
Aspect Dilutive equity (Seed / Series A) Non dilutive incentives (R&D tax, grants, loans)
Impact on ownership Reduces founder and early investor stake Preserves equity
Typical ticket size Millions, linked to significant dilution Tens or hundreds of thousands, sometimes millions over time
Investor expectations Rapid growth, ARR, product market fit Clear R&D plan, innovation, value for money
Speed to access Lengthy fundraise and due diligence cycles Faster once a repeatable process is in place
Risk profile Long term control and governance implications Compliance and reporting risk if poorly managed
Best use Scaling teams, go to market, acquisitions De risking R&D, pilots, technical hiring, equipment and tooling

FI Group’s Seed to Series A proposition is to professionalise the non dilutive side of this table so founders and CFOs can focus on building and selling, not managing applications and enquiries.

Deep tech CFO pain points between Seed and Series A
Deep tech CFO pain points between Seed and Series A

Deep tech CFOs are asked to deliver global growth, manage complex R&D portfolios and preserve runway, all while dealing with evolving incentive regimes and increasing compliance scrutiny on R&D claims. The result is often fragmented, reactive use of non dilutive funding.

Common pain points we see in Seed to Series A clients include:

  • Regulatory complexity
  • Compliance and enquiry risk
  • Fragmented global approach
  • Opportunity cost of internal delivery
  • Unstructured funding stack

FI Group’s role is to identify these gaps, set a structured roadmap and then execute it with a mixture of UK and international expertise.
