Trying to make sense of the types of biotech companies before a job search? You can sort them two ways: by what they work on (medicine, farming, industry, marine) and by what role they play (developer, service provider, tools maker).
This guide is part of our wider look at the biotech industry, and it focuses on how the company types differ for people planning a career.
| Item | Value |
|---|---|
| Red biotechnology | Medicine and human health |
| White biotechnology | Industrial |
| Green biotechnology | Agriculture |
| Blue biotechnology | Marine and fresh water |
| Global CDMO market, PharmaSource estimate | Approximately $220 billion in 2025 |
Figures come from AZoLifeSciences and PharmaSource. Market estimates and definitions can change, so check the sources before you rely on them.
Sorting biotech companies by the colors of biotechnology
The most common way to group the field is by application, using a color code. The main colors are white (industrial), green (agriculture), blue (marine and fresh water) and red (medicine and human health), according to AZoLifeSciences.
Other colors exist too, including yellow, gold, purple, brown and grey. Sources disagree on exactly what each extra color means, so treat the four main ones as the reliable core.
Red: medical and drug-development companies
Red biotechnology is also called biopharmaceuticals and involves biotechnology in the medical field. It covers clinical trials, vaccine development, disease research, antibiotic production, drug development and molecular diagnostics.
This is where most people picture a “biotech company.” Typical employers in this group include:
- Drug developers working on antibodies, gene therapies, cell therapies or vaccines.
- Diagnostics companies building molecular tests.
- Regenerative medicine startups.
Careers here lean on research, clinical operations and regulatory work. If you are curious how a product reaches patients, the fda approval process explains the U.S. regulatory path for medicines.
White, green and blue: industry, agriculture and the ocean
White biotechnology is arguably the largest area of biotechnology. It revolves primarily around biocatalysts used for industrial-scale production and processing of products.
Green biotechnology works on food production and on less environmentally damaging fertilizers and biopesticides. Techniques range from tissue cultivation and micropropagation to genetic engineering.
Blue biotechnology draws on marine biodiversity. It has produced compounds such as cytarabine, which treats leukemia, and ziconotide, a synthetic analgesic equivalent of a peptide found in marine snail venom.
These groups hire many of the same skills as red biotech, such as fermentation, molecular biology and process engineering, but the products and pace differ.
Developers versus service providers
Another split ignores color and asks what the company does in the drug pipeline. Contract companies run much of the pipeline for others, and PharmaSource estimates the global CDMO market at approximately $220 billion in 2025.
- CRO (contract research organization): specializes in research and clinical development, with services such as protocol development, patient recruitment, clinical monitoring, data management and regulatory submissions.
- CMO (contract manufacturing organization): focuses specifically on the manufacturing of pharmaceutical products.
- CDMO (contract development and manufacturing organization): offers integrated development and manufacturing solutions.
In practice, a small developer may have only a handful of staff and rely on these partners. A service provider may work across several client projects, while a developer may depend on a small number of programs.
What the work looks like inside each type
The label on a company tells you less than the daily work does. Two firms in the same color can offer very different jobs, so it helps to picture the roles behind each type.
Developers of medicines
A red biotech developer usually builds a team around a small number of programs. Scientists run experiments on a target, process specialists work out how to make the product consistently, and clinical and regulatory staff plan how to test it in people.
Many of these companies keep manufacturing outside the building. That means roles in project management, quality and vendor oversight matter as much as bench science.
Service providers
At a CRO, the work is organized around client studies. You might handle data, monitor trial sites or prepare documents for regulators, and you often move between projects and sponsors.
At a CMO or CDMO, the work centers on the plant and the process. Typical roles include process development, manufacturing operations, quality control, quality assurance and technical transfer from a client’s lab to production scale.
Industrial, agricultural and marine firms
White biotechnology firms tend to focus on scale: getting an enzyme or fermentation process to work efficiently in large vessels. Green biotechnology firms combine laboratory work with field testing, so the job may take you outside the lab.
Check each posting closely, because the same job title can mean different things across these areas.
Where the lines blur
Real companies rarely fit one box. A firm can develop its own medicine while also selling services, and a large service provider can combine research and manufacturing under one roof.
PharmaSource describes this overlap when it says CROs, CMOs and CDMOs each specialize in supporting specific phases of the pipeline. The categories describe a main focus, not a strict fence.
Terms such as biotech and biopharma are also used loosely. Some people use biotech for smaller research-driven developers and biopharma for the wider group that includes large drugmakers, but there is no single agreed definition. When a job ad uses one of these words, read the description of the actual work instead of the label.
- Look at what the company sells: a product, a service or a platform.
- Look at what the team does each week: research, development, manufacturing or support.
- Look at where the products are headed: patients, farms, factories or the sea.
How funding and size change the experience
Within any type, company stage matters as much as category. An early-stage startup may depend on investors, so understanding biotech startup funding helps you judge how long a company can keep going.
Larger and more established firms usually offer more structure and defined roles. Smaller firms often give you broader responsibility, along with more uncertainty.
Funding also shapes how a company behaves. A firm backed by investors tends to move fast toward milestones, while a service provider earns revenue from clients and can look steadier from the outside.
Neither path is better for everyone. Early-career readers often value the breadth a small team gives, while others prefer the training and clear career ladders of a bigger organization.
Whatever type you lean toward, it pays to read a company’s website, pipeline page and job postings together. They show what it builds, what it outsources and which skills it keeps hiring for.
When you compare employers, ask these questions:
- Which color of biotech is the product in?
- Does the company develop its own products or serve others?
- What stage is it at, and how is it funded?
Frequently asked questions
What are the main types of biotech companies?
Show answer
By application, the main groups are red (medicine), white (industrial), green (agriculture) and blue (marine), per AZoLifeSciences. By role, you will also find CROs, CMOs and CDMOs that serve developers.
Is red biotechnology the same as biopharma?
Show answer
AZoLifeSciences says red biotechnology is also referred to as biopharmaceuticals. Other sources use the terms more loosely, so check how an employer defines itself.
What is the difference between a CRO and a CDMO?
Show answer
A CRO focuses on research and clinical development, while a CDMO offers integrated development and manufacturing, according to PharmaSource.
Do all color categories agree across sources?
Show answer
No. The four main colors are broadly consistent, but sources assign extra colors such as yellow, gold, purple, brown and grey differently.
