About this formation
What almost every one of these nine companies is chasing is not a new drug so much as a new targeting mechanism, a way to make an existing therapeutic modality show up only where the tumor is and behave differently everywhere else. SynsoryBio's proteins that "sense where they are in the body," Eugit Therapeutics' tissue-specific delivery, and Granza Bio's programmable immune particles are all variations on the same wager: that the ceiling on cancer treatment is precision, not potency. That's a real departure from the older idea of oncology as finding the most powerful cytotoxic agent, and it shows up even in the vaccine and cell-therapy players, since Adventris is going after KRAS specifically because broad immunogenicity has failed so often, and Modulari-T is building synthetic gene switches rather than a single fixed therapy. The timing tracks with the maturing of programmable and AI-guided protein design tools since around 2022, which made it practical for small startups, rather than only large pharma, to engineer conditional activation and explainable targeting platforms like Serinus Biosciences claims. What's striking is the gap between this formation's 3.08x growth and the 0.45x rate of the broader "Cancer Therapeutics" and "Therapeutics" formations it sits inside, suggesting founders and capital are concentrating specifically in precision-delivery oncology while the rest of therapeutics broadly cools. That divergence implies investors increasingly treat "another cancer drug" and "a new way to aim a cancer drug" as fundamentally different bets, with the latter absorbing a disproportionate share of new formation activity.
Open questions naming this formation — 4
OPEN
Regulatory/IND-filing consultancy focused on synthetic biology oncology therapeutics
Several companies (Granza Bio, SynsoryBio, Modulari-T) use novel synthetic biology mechanisms in oncology, which don't fit standard FDA precedent pathways, implying a need for specialized regulatory navigation services distinct from traditional biotech regulatory affairs.
NEXT INVESTIGATION
Check back around November 2027 for new YC batches, to see whether independent evidence for "Regulatory/IND-filing consultancy focused on synthetic biology oncology therapeutics" has appeared.
OPEN
Biomarker/patient-stratification data platforms for precision oncology drug discovery
Companies like Velorum Therapeutics, Adventris Pharmaceuticals, and Eris Biotech focus on drug discovery and therapeutics broadly in oncology, which increasingly requires patient stratification tools to de-risk trials — a capability layer not yet visible among the listed companies themselves.
NEXT INVESTIGATION
Check back around October 2027 for new YC batches, to see whether independent evidence for "Biomarker/patient-stratification data platforms for precision oncology drug discovery" has appeared.
OPEN
Shared manufacturing/CDMO capacity for cell and gene therapy oncology startups
Modulari-T, Eugit Therapeutics, and Granza Bio all sit in cell/gene therapy synthetic biology for oncology, a space historically bottlenecked by expensive, scarce GMP manufacturing capacity, suggesting a coming wave of demand for accessible CDMO infrastructure tailored to smaller startups.
NEXT INVESTIGATION
Check back around August 2027 for new YC batches, to see whether independent evidence for "Shared manufacturing/CDMO capacity for cell and gene therapy oncology startups" has appeared.
With multiple companies (Eugit Therapeutics, Modulari-T, Granza Bio, SynsoryBio) building synthetic biology and cell-therapy oncology assets, they'll each need specialized in vivo/ex vivo validation pipelines that generic CROs aren't optimized for, creating demand for a shared testing infrastructure layer.
NEXT INVESTIGATION
Check back around August 2027 for new YC batches, to see whether independent evidence for "Contract preclinical/translational testing platforms specialized in cell & gene oncology modalities" has appeared.

Inside Oncology
Biotech
A primary internal company segment within Oncology, derived deterministically from the shared yc tag “Biotech”. This is a classification of current window members, not a causal layer or a separate time trend.
Other / unclassified
Measured-window members of Oncology that could not be assigned to a narrower shared YC tag or industry without forcing a classification.
