The company was co-founded by two individuals with complementary expertise: Sujal Patel, a successful technology entrepreneur and former CEO of Isilon Systems, and Dr. Parag Mallick, an Associate Professor at Stanford University specializing in proteomics.

Initial capital/funding

Early development was supported by seed funding, which was followed by a significant $18.5 million Series A round in 2018, led by firms like Andreessen Horowitz.

Given Company's Evolution Milestones

Given Company's Transformative Moments

The single most transformative decision for Nautilus Biotechnology was its choice to go public in 2021 via a SPAC merger, rather than a traditional Initial Public Offering (IPO). This move accelerated the funding timeline, providing the necessary capital to sustain a multi-year development cycle for a revolutionary platform.

• Securing Long-Term Capital: The SPAC merger, completed in June 2021, raised about $345 million in gross proceeds, giving the company a substantial financial cushion for its ambitious R&D program. This funding was critical because the platform is a deep-science undertaking that requires years of investment before generating meaningful revenue.
• Operational Discipline in 2025: Despite being pre-commercial, the company has shown a focus on operational efficiency. For example, third-quarter 2025 operating expenses were $15.5 million, a 19% decrease compared to the prior year period, which helps preserve the cash runway.
• Shifting Commercialization Focus: The commercial launch of the Proteome Analysis Platform, initially targeted for 2025, has been delayed to late 2026, a necessary adjustment due to the complex refinement of the core technology. This delay is a realistic acknowledgment of the difficulty in scaling a novel technology. The initial instrument package is planned to be priced around $1 million.
• External Validation: The successful deployment of the first external field evaluation unit in November 2025 is a major step, moving the technology from internal testing to independent, real-world research. This external data generation is essential for building market credibility ahead of the 2026 launch.
