The push away from animal models is a technical necessity, not just an ethical one. Advanced therapeutics like T-cell engagers and multispecific antibodies depend on human-specific biological pathways. These mechanisms are not accurately reproduced in animal models, rendering them ineffective for testing these new drug classes.

To avoid overfitting and prove true generalization, Bolts validates its protein design models by testing them across a wide array of targets from over 25 external academic and industry labs. This diverse, real-world testing is the ultimate benchmark of a model's utility in drug discovery.

Instead of using CRISPR for gene editing (cut and replace), Seek Labs harnesses its natural function. Their platform programs CRISPR to find and 'chop up' viral DNA and RNA, directly lowering the viral load and allowing the host's immune system to take over.

Founder Sean Ainsworth intentionally started his pioneering AAV gene therapy in an ocular setting before any Western approvals existed. Because an intravitreal injection uses a very small vector amount, it provided a significant safety advantage and a manageable way to prove the technology before attempting systemic delivery.

Unlike ventures in established biological pathways, startups tackling novel biology must first prove a specific drug product can work. The primary question isn't about the platform's potential applications but whether a single, tangible therapeutic is viable. Focusing on a broad platform too early is a mistake.

Instead of hoarding early capital, Actuate's CEO synthesized a kilogram of their molecule and sent it to labs worldwide. The goal was to fail fast by seeing if promising results could be replicated, a crucial de-risking step before committing larger funds.

The company's BioSeeker AI platform goes beyond discovery. After analyzing genomic data, it directly outputs the functional components for development: the 'guides' for their CRISPR therapeutics and the 'primers and probes' for their diagnostic tests, making AI a rapid creation tool.

Unlike using genetically identical mice, Gordian tests therapies in large, genetically varied animals. This variation mimics human patient diversity, helping identify drugs that are effective across different biological profiles and addressing patient heterogeneity, a primary cause of clinical trial failure.

The company intentionally makes its early research "harder in the short term" by using complex, long-term animal models. This counterintuitive strategy is designed to generate highly predictive data early, thereby reducing the massive financial risk and high failure rate of the later-stage clinical trials.
