VC Radiology Funding Drops

Venture capital investment in radiology peaked in 2021 at just over $2B and has been on a slow decline since then. That’s according to a study in JACR that documents the ebb and flow of VC investment, in particular its shift to companies developing AI algorithms. 

VC investment is the lifeblood of any industry built on innovation, and healthcare is no exception. 

  • Venture capital funding helps many innovators bring their ideas to fruition and helps fund them until revenue from product sales can start rolling in.

So it stands to reason that changes in VC funding levels can have ripple effects, with declines potentially affecting the rate of new technology development.

  • Indeed, some studies have found that every 1% increase in interest rates can cause a 3% decline in R&D spending and a 9% drop in patent filings.

The new research tracks VC funding specifically in radiology, with researchers from Emory and Harvard universities using PitchBook to track VC investments from 2000 to 2023. 

In particular, researchers found…

  • A total of $11.4B was invested in 646 radiology companies during the entire study period. 
  • The average investment was $6.3M with an average $51M post-investment valuation.
  • VC investment activity in radiology peaked in 2021 at $2.18B.
  • Medical devices attracted 28% of investment, followed by AI healthcare software (22%), non-AI healthcare software (18%), healthcare services (14%), and biotechnology and drug discovery (18%).

The new data track with research from other sources – like Signify Research – that have also documented a slowdown in radiology VC investment, particularly in AI. 

  • Most sources attribute the declines to the end of the “cheap money” era during the COVID-19 pandemic as governments began dialing back on stimulus payments and started raising interest rates to tamp down inflation. On the other hand, other research has found that the recent declines are occurring at a rate that’s not proportional to inflation or interest rates alone.

The Takeaway

The new JACR research comes as the investment and healthcare worlds are set to begin their annual courtship ritual next week at the J.P. Morgan Healthcare Conference in San Francisco. Undoubtedly these new findings will be a point of discussion as radiology companies look to secure the capital that will fuel the next innovations in medical imaging. 

VC AI Funding Plummets

If you thought venture capital funding of AI firms was lower last year, you weren’t wrong. A new report from market analysis firm Signify Research found that VC funding of radiology AI firms dropped by nearly half in 2024 compared to the year before. 

VC funding has become a closely watched barometer of the radiology AI segment’s overall health. 

  • As most AI developers haven’t generated significant cash flows from product revenues yet, VC money is the oxygen that keeps AI firms breathing. 

And there are signs that after peaking in 2021, that oxygen is coming into short supply. 

  • Signify’s report last year documented a 19% drop in VC AI funding in 2023, a development attributed to tighter access to capital due to high interest rates. 

Those trends continued into 2024, with the new Signify report finding …

  • Total VC funding was $335.5M, down 48% compared to $645.6M in 2023.
  • The number of funding rounds fell 35% (20 vs. 31), to the lowest level since 2015.
  • Average deal size fell 16% ($16.8M vs. $20.1M).
  • Cleerly raised the most in 2024 with $106M in funding, followed by Qure.ai with $65M (putting Qure into Signify’s elite “$100M Club”). 
  • Funding declines were even worse in the Asia-Pacific (-84%) and the Europe, Middle East, and Africa regions (-76%) compared to the peak in 2021. 

Signify analyst Umar Ahmed noted that 2025 got off to a strong start, with $100M in funding rounds announced in January.

  • This could either represent a rebound in investor confidence, or indicate that the AI funding cycle is getting longer as VC firms put developers under the microscope and demand better ROI for their investments. 

The Takeaway

So it’s agreed that 2024 was a wash for VC radiology AI funding – what about 2025? The year’s strong start appears to have petered out as we approach the spring quarter, and ongoing regulatory turbulence and economic uncertainty in the U.S. isn’t likely to help. Stay tuned.
