Editorial Overview

Founded in London in 2015 by Ashmita Das and Vivek Vyas, Kolabtree fills a vital and underserved niche: connecting businesses that need deep scientific expertise with freelance researchers and PhD scientists. Small biotech startups, food manufacturers, and healthcare agencies use Kolabtree to hire experts for formulation development, literature reviews, clinical study design, and FDA regulatory documentation.

For academics and scientists who want to monetize their specialized knowledge outside traditional university tenures, Kolabtree offers projects with high billing potential ($50 to $200+/hour, or fixed project fees of $1,000 to $10,000+). However, it is an unapologetically elite academic platform: you must hold a Master's or PhD degree in a STEM field, and Kolabtree deducts a hefty 20% fee from freelancer earnings. It provides no accessible opportunities for general workers without scientific backgrounds.
