As a strategically focused CDMO, Excellos combines the best of both worlds: the tailored, consultative support of a boutique firm with the scientific and operational strength needed to support complex, high-stakes programs. We offer bespoke solutions across the full development lifecycle, from donor-sourced starting material to final product characterization. Our model is intentionally focused: we’re structured to move quickly, collaborate deeply, and adapt to your unique needs without compromising quality or scalability. With a foundation rooted in clinical experience, a close partnership with the San Diego Blood Bank, and a culture of scientific rigor, Excellos brings both precision and flexibility to every engagement — helping our partners accelerate progress with confidence.
