How third-party payer models help impact startups scale
Mission-driven startups often build for people who are underserved or vulnerable. The problem is that the people who benefit most may be unable or unwilling to pay enough for the product or service to support venture-scale growth.
That can force a false choice between commercial scale and impact. Nicholas Andreou’s argument is that founders should look beyond the end user and identify a third party whose incentives align with either the outcomes created or the activities that produce them.
Key takeaways
A direct-to-consumer model can limit both access and growth when the end user has a low ability or willingness to pay.
A third-party payer is a customer that funds the service without being its direct user.
The strongest candidates either benefit from the outcome or already pay for an activity the startup can perform more effectively.
When payer incentives and user outcomes align, a startup can strengthen both its impact model and its commercial model.
The challenge, in the current venture context, is linking those impact models with viable revenue models.
Why direct-to-consumer revenue can constrain impact
If a startup assumes that the end user must also be the customer, it may have to choose between serving people with a greater ability to pay and reaching those with the greatest need. Either choice can constrain the business: prioritising access may weaken the investment case, while prioritising revenue may narrow the intended impact.
The alternative is to separate the user from the payer.
What is a third-party payer model?
A third-party payer model is a revenue model in which an organisation pays for a product or service used by someone else. An employer paying for an employee benefit is one example.
For an impact startup, the model works when the payer has a credible reason to fund the service. Andreou identifies two broad patterns: the payer values the outcome, or the payer values an activity that produces the outcome.
Model 1: Find a payer invested in the outcome
The first route is to identify an organisation that benefits when the startup achieves its intended social or environmental result.
Government and public systems
Government can be a viable payer because it has a direct interest in public wellbeing. In healthcare, for example, a public system may fund preventive support when better outcomes can reduce pressure elsewhere.
Second Nature illustrates the pattern. Its behavioural programme helps people at risk of diabetes manage their weight. A consumer subscription made the product available to those who could pay, but risked excluding lower-income users. By partnering with the NHS, Second Nature could extend access while building a different route to revenue.
Employers
Employers can play a similar role when employee wellbeing also affects organisational performance.
Wagestream offers financial-wellbeing services through employers. One product is earned wage access, which lets employees draw down wages they have already earned before payday. Employees may gain flexibility and reduced financial stress; employers may benefit from improved retention and productivity. The business model depends on that alignment between the user’s outcome and the payer’s interests.
Model 2: Find a payer invested in the activity
Sometimes no obvious customer is willing to pay for the impact itself. The second route is to identify an organisation that already pays for an activity associated with producing that impact.
Olio: monetising waste management, not the impact outcome
Olio enables people to share unwanted food in their communities, helping to reduce waste and address hunger. Those outcomes matter, but they do not automatically reveal a willing and able payer.
Food businesses, however, already pay to dispose of surplus food. Olio recognised that it could serve that operational need regardless of whether a business was primarily motivated by the social or environmental outcome. The activity created a viable customer relationship while preserving the impact mechanism.
Oyster: applying a proven buyer model to a new impact goal
Oyster uses another established purchasing dynamic: companies pay for HR services that help them hire and manage people remotely.
Its impact ambition is to widen access to employment by encouraging companies to consider talent beyond established labour markets, including people in emerging markets. The customer pays for a familiar business activity, while the product can expand opportunities for workers who might otherwise be overlooked.
How founders can assess a third-party payer opportunity
The examples suggest three practical questions:
Who benefits from the outcome? Look for institutions that gain economically, operationally or socially when the user’s situation improves.
Who already pays for the underlying activity? Existing budgets can reveal a customer even when the impact outcome itself is difficult to monetise.
Does the model preserve the intended impact? Separating the payer from the user should widen access without changing the product’s core purpose.
What this means for investors
For investors, the central question is not only whether an impact model is credible, but whether it is connected to a scalable source of revenue. A well-aligned third-party payer can improve the commercial case without requiring the company to reduce its impact ambition.

Link the impact model to a viable revenue model
Impact potential alone does not create a venture-scale business. The challenge is to connect a valuable outcome with a payer that has both the incentive and the ability to fund it.
Third-party payer models offer two routes: find a customer that values the outcome, or find one that values the activity producing it. When that alignment is real, founders can expand access, strengthen the investment case and scale impact alongside financial performance.
