When a biotech company needs to fill a critical role through an outside firm, it usually chooses among three broad models: retained, contingent, and a hybrid sometimes called engaged or container search. Each can work well. Each can work badly when it is matched to the wrong hire.
The differences are less about fees than about incentives. How a search firm is paid shapes how it allocates time, which candidates it pursues, and how carefully it represents your company to people who are not looking for a new role.
How the three models differ
In a retained search, the company engages one firm exclusively and pays its fee in installments over the course of the search, usually beginning at kickoff. In return, the firm commits dedicated time to map the market, approach candidates directly, assess them in depth, and manage the process through offer and start date.
In a contingent search, the firm is paid only if a candidate it presents is hired. These searches are often non-exclusive, so several firms may work the same role at once. The model rewards speed and volume, and it works best when qualified candidates are relatively easy to identify and many are actively looking.
Hybrid models sit between the two. Part of the fee is paid upfront to secure commitment, with the balance due on placement. They can suit roles that need more than a contingent effort but do not call for the full depth of a retained search.

Matching the model to the hire
The right choice depends on the role, the market for that profile, and the cost of getting it wrong. A few patterns tend to hold.
- Retained search suits C-suite and board roles, confidential replacements, and scarce profiles, such as a CMC leader with late-stage biologics experience or a CMO with a specific therapeutic area and regulatory history.
- Contingent search suits roles with a well-defined skill set and a broader candidate pool, such as clinical research associates, bench scientists, or several similar hires at once.
- Hybrid models suit director-level and senior individual contributor roles where the market is competitive but the stakes do not justify a full retained process.
Timing plays a part as well. A retained search can take longer to produce a first slate, because it begins with research rather than with candidates already in circulation. In exchange, you see a fuller picture of the market. If an interim leader can hold the role for a few months, that depth is often worth the wait.
Confidentiality deserves particular weight. If you are replacing an incumbent, entering a new therapeutic area, or building a function that signals strategy, a single retained firm working under a clear confidentiality agreement is usually the safer choice. Several firms circulating the same brief can expose plans you would rather keep private.
Questions to ask any firm
Whatever the model, the people doing the work matter more than the structure. Before engaging a firm, ask direct questions and expect direct answers.
- Who will run the search day to day, and how many other active searches are they carrying?
- Which organizations are off limits because they are current clients, and how does that narrow the candidate pool for this role?
- How will you describe our company, our science, and our financing position to candidates, and can we review that narrative?
- What happens if the person we hire leaves within the first year?
- How will you assess candidates beyond the CV, including references and judgment?
Off-limits policies matter more in a concentrated industry. A firm that serves many companies in your therapeutic area may be unable to approach the very people you most want to meet. That is not a reason to avoid the firm, but it should be discussed openly at the start.
Finally, consider what you are buying beyond a list of names. For a critical hire, a good partner helps define the role, challenges assumptions about the profile, and gives you an honest read on how the market sees your company. That counsel is often the most valuable part of the engagement, and it is hard to get from a model built around speed alone.
There is no universally right answer. There is a right answer for the specific hire in front of you, and it is worth choosing deliberately rather than by habit.
