The short answer for most DeepTech founders: sequence your funding rather than pick a single source. Non-dilutive government and university grants are typically used to prove the science before significant venture investment; traditional venture capital funds the journey from prototype to scale; and corporate venture capital can add strategic resources alongside capital at later stages. The right mix depends on your technology's maturity, the risks you still carry, and how much equity and control you are willing to trade.

Understanding DeepTech Funding: Unique Challenges and Pathways

DeepTech companies are built on scientific or engineering breakthroughs rather than code and distribution, and that changes their financing math. A guide from Boston Consulting Group maps the journey from an idea isolated on the basis of scientific research through prototype iterations, a product ready to scale, and eventual commercialization, at typical funding amounts ranging from roughly $1 million to $5 million at seed stage to more than $100 million in the growth phase.

According to a knowledge base maintained within MIT's startup-support ecosystem, most traditional venture funds are optimized for software-style businesses and structured as ten-year funds, a timeline that is too short for science-based startups. As that analysis puts it, "the typical angel, seed, A, B, C round structure rarely applies" to these companies, so founders often stay in the lab longer to mature the underlying science before raising equity capital.

The consequence is a distinct capital landscape: grants early, specialized equity later. The following sections unpack each stage and each source.
