This recognition highlights our dedication to pushing the boundaries of scientific and biotech web design, creating digital experiences that communicate complex technology clearly while inspiring trust and engagement.


What This Recognition Means

Being elevated to finalist status means our work impressed both the public and the DesignRush jury. Our project is now receiving enhanced visibility across DesignRush’s finalist showcases as we await the final selection of winners.


Project Overview and Design Vision

For Spear Bio, a company founded out of Harvard that develops ultra sensitive immunoassays, our challenge was to translate powerful science into digestible storytelling. We needed a site that spoke to both researchers and investors, balancing credibility with visual impact.

Our approach included:

  • Scroll triggered animations and custom motion: Dynamic visuals guide visitors through the technology in an intuitive narrative
  • Abstract protein inspired motifs and refined palette: The visual identity references proteins and molecules while maintaining a professional, approachable style
  • Interactive infographics and parallax transitions: Complex concepts are broken down into interactive visuals that visitors can explore with ease
  • Performance and scalability: Despite rich visuals, performance remained a top priority. We built a flexible CMS that allows Spear Bio to scale and update content seamlessly
  • On page SEO and fast loading: Optimizations ensure the site ranks for key terms while delivering a smooth user experience

Third Party Validation

DesignRush’s coverage affirms many of these decisions, noting that the site uses animations and transitions to turn complex science into an intuitive visual narrative. They also highlight how abstract visuals paired with modern UX choices create a compelling and immersive user experience.


Why It Matters

This recognition reinforces our belief that biotech web design should be as innovative as the science behind it. When design is aligned with clarity, aesthetics, and storytelling, even the most complex ideas can become engaging and meaningful to diverse audiences.


Thank You

We thank Spear Bio for trusting us to bring their vision to life and DesignRush for recognizing this work.
