How Deep Tech Startups Can Navigate the Funding Challenges at Every Stage of Commercialisation

Written by Laura Sheedy | 10 April 2025

Deep tech startups face unique hurdles in securing funding. Their long development cycles, high R&D costs, and complex technologies require a strategic approach to fundraising.

Funding a deep tech startup isn’t just challenging, it can be a journey through uncharted territory. The path isn’t always linear, and finding the right funding at each stage can be a complex puzzle.

So, how does a deep tech startup secure funding realistically? 

Cicada Innovations and Radium Capital hosted ‘Not Your Usual Funding Conversation', where we asked venture capitalists, R&D loan experts, government funding specialists, and founders, what are the challenges and the no-fluff strategies deep tech startups need to secure funding at every stage of their commercialisation journey. 

Our panel featured experts Emerald Scofield, (Main Sequence Ventures), Jessica Olivier (RSM Australia), Pat Stewart (Radium Capital) and Dr Venkata Gutta (Millibeam), who shared their comprehensive insights into how to navigate early-stage funding, the importance of strategic partnerships, and how to actually secure investments, leverage government grants, and structure businesses for growth. 

Read on as they share their non-negotiables on how to secure funding for your deep tech startup.

Early-Stage R&D and Proof of Concept  Challenges

Deep tech startups in the 'early R&D and proof of concept' phase face significant challenges due to their inherently high-risk nature, as investors carefully evaluate founder capabilities, the potential market fit, and the technological feasibility of the innovation.

Startups often operate with limited or no revenue, relying heavily on funding to support ongoing research and development. This makes managing high R&D costs and controlling cash burn critical. Founders must not only convincingly demonstrate the technological feasibility of their ideas, but also prove their potential for real-world applications beyond the lab. Securing early industry partnerships and validating customer interest is essential but challenging. Furthermore, aligning R&D efforts with actual market needs is crucial to ensure commercial viability.

To navigate this, it is recommended that startups should:

  • Build credibility and trust with potential investors, focusing on strengthening relationships with venture capitalists (VCs) early, even before seeking funding.
  • Leverage government funding options, such as R&D grants and state incentives: NSW MVP Grant and the NSW Small Business Innovation & Research (SBIR) Program, with strategic planning and meticulous documentation.
  • Showcase founder capability and "get shit done" attitude.
  • Supplement technical expertise with commercial acumen.
  • Navigate the complexities of early-stage intellectual property protection by creating a clear IP strategy and getting legal advice early on.
  • Start developing a clear picture of the target market.

Prototyping & Early Trials Challenges

During the 'prototype and early trials' phase, deep tech startups face the critical challenge of licensing the technology, commencing trials and proving technological feasibility with real-world applications, while also managing high R&D costs.

To overcome this:

  • Utilise government funding, such as the R&D tax incentive and commercialisation grants, including the Industry Growth Program.  Speak to Radium Capital for more information.
  • Prioritise early customer engagement and gather real market interest over Letters of Intent (LOIs).
  • Focus on demonstrating key metrics that potential customers require.
  • Seek feedback from potential future investors on what milestones are needed to secure further funding.
  • Begin to build a strong network of potential customers and industry partners.

Transitioning to Commercialisation Challenges

The 'transitioning to commercialisation' stage presents deep tech startups with the significant challenge of securing substantial funding for production and team growth, requiring a delicate balance between securing certifications, equity, grants, and loans to avoid dilution. The complex transition from R&D to manufacturing and market entry demands strategic partnerships and collaborations, while long-term sustainability hinges on meticulous planning and securing consistent funding.

To navigate this, startups need to: 

Scaling and Market Entry Challenges

For deep tech startups aiming for global expansion, securing significant funding within Australia is often difficult, compelling them to seek international investment. To attract growth and investors, they must clearly showcase strong revenue potential and the ability to scale. Cultivating relationships with these investors and aligning with their expectations is paramount. Successfully navigating the complexities of diverse international markets and regulatory landscapes is a key challenge, requiring a robust and experienced leadership team to manage the expansion effectively.

Startups during this stage need to:

  • Build relationships with growth investors early and understand their expectations.
  • Explore government export grants and venture debt. This includes the EMDG program (see above) and the Venture Capital Limited Partnership (VCLP) Program. 
  • Focus on demonstrating a strong track record of growth and market penetration.
  • Build a well-structured company with an experienced leadership team.
  • Consider international expansion strategies and build global networks.

Key Takeaways For Founders:

  1. Prepare Early – Start conversations with investors and grant bodies before you need funding.
  2. Leverage Non-Dilutive Funding – Grants and tax incentives can complement equity financing.
  3. Customer Validation is Crucial – Engage with potential customers early to guide R&D efforts.
  4. Structure Your Business Right – Proper legal and financial setup prevents future issues.
  5. Build the Right Team – Hiring commercial expertise alongside technical talent is key.
  6. Strategic Partnerships Matter – Collaborating with competitors and industry players can accelerate growth.
  7. Plan for the Long Game – Fundraising takes time, so always be thinking a few stages ahead.
