Fit Biomics is a biotechnology company spun out of Harvard University, pioneering the next generation of health through microbiome innovation. Our flagship products, Nella and V
· Nella, are clinically backed performance probiotics derived from elite athletes, supporting sleep, digestion, fatigue, recovery, and exercise motivation. Our founding research was published in Nature Medicine, and our human clinical data was published in Microbiome Journal.

We are a small, mission driven team of scientists, athletes, and creatives who believe in defying limits and elevating human potential from the inside out.

We are looking for a Go To Market and Growth Intern to own the channels that turn partnerships into revenue: ambassador and affiliate programs, practitioner and wholesale relationships, and the measurement systems that tell us what is working.

Where our Business Development and Partnerships Intern opens doors, this role makes what comes through them perform. You will run affiliate and code programs end to end, manage activation logistics and follow through, and own the numbers that leadership uses to decide where Fit Biomics invests next.

This role is geared toward students in the final year of their program and recent graduates who are ready to step into a career. Fit Biomics intends to make its first full time BD/GTM hire at the end of this internship cycle, and the strongest performer will be first in line.

We welcome applicants from business, marketing, economics, and communications backgrounds, and from science backgrounds with a commercial or analytical bent.

Ambassador and affiliate growth

• Onboard trainers, practitioners, and community leaders into our ambassador and affiliate programs
• Set up and manage discount codes, tracking links, and payout records
• Run the seed and follow up cadence: personal supply shipped, day 7 check in, day 21 protocol proposal, reorder conversation
• Identify which ambassadors actually convert and double down on them

Channel and activation execution

• Manage sampling activation logistics from confirmation through event day: product, materials, staffing, and follow up capture
• Support wholesale and retail placements, including practitioner kits, shelf materials, and sell through tracking
• Coordinate corporate pilot mechanics: cohort setup, baseline and day 60 surveys, and readout preparation
• Keep every activation measured, because unmeasured activations do not get renewed

Growth analytics and reporting

• Own conversion tracking across codes, activations, and channels
• Build and maintain the weekly growth report: what ran, what converted, what reorders
• Analyze which verticals and plays produce the best return, and make recommendations
• Maintain data quality across the tracker, CRM, and code systems

Required

• Final year undergraduate or graduate student, or graduated within the past two years
• Comfortable with numbers: spreadsheets, conversion metrics, and basic analysis are daily work
• Strong written communication for partner and ambassador correspondence
• Highly organized. This role is the operational backbone of the commercial function.
• Genuine interest in health, wellness, fitness, and science backed products

Preferred

• Experience with affiliate, ambassador,…
