Challenging the notion that biotech requires large teams for clinical progress, Coursera Health operates with just nine people. This small team is managing one Phase 1 trial while initiating a second and developing an AI platform. This demonstrates how a focused, highly experienced team can achieve major milestones with extreme capital efficiency.

While a challenging fundraising market seems negative, it forces startups to operate with discipline. Unlike in frothy markets where companies expand based on hype, the current climate rewards tangible results. This compels a lean structure focused on high-value projects, creating a healthier long-term business model.

By deliberately not over-raising, biotech startups preserve M&A optionality. A seemingly modest exit, like Surf Bio's $400M acquisition, can be a massive win for founders and early investors if the company remained lean, avoiding the need for a billion-dollar outcome.

While biotech cannot easily replicate tech's rapid iteration cycles due to high costs and long feedback loops, it can adopt the capital efficiency model of tech seed investing. The strategy is to kill flawed projects quickly and cheaply, ensuring that when you lose, you lose small.

Actuate Therapeutics maintains high capital efficiency by keeping its full-time headcount low. The company is built around a trusted core team and supplemented by an extensive stable of "best of breed" consultants who are engaged on an as-needed basis, minimizing overhead costs.

For small biotechs, the playbook for success extends beyond scientific discovery. It requires creativity and innovation in the operational process itself—finding efficient paths through regulatory checkpoints, securing non-traditional funding, and leveraging external resources to advance development with limited capital.

CRISPR's CEO suggests a specific financial rule: never spend more than 11% of market cap in one year. Spending above 14-15% risks a 'dilution spiral,' while spending only 6-7% means you aren't taking enough aggressive risks. This provides a clear guardrail for R&D investment.

Iolyx Therapeutics' CEO notes the surprising capital efficiency of lean biotech. Her team advanced a drug from discovery through Phase 2 for approximately $20 million—an amount she could have easily spent on a single marketing campaign at Genentech. This highlights the operational leverage of focused, small teams.

Ona Therapeutics maintains a small team by following a simple rule: outsource functions that external experts can do better (like CROs and manufacturing) at a reasonable price. This allows them to focus all internal resources on their core, specialized competency of designing novel molecules and advancing their pipeline.
