ASSET BASED CONSULTANCY
Eristotle takes an asset-based consultancy approach to help our clients achieve more efficient, repeatable, and value-driven results. This model contrasts with traditional consulting, which often relies heavily on bespoke, one-off project designs.
By leveraging our own proprietary tools, frameworks, methodologies, and other intellectual property (“assets”), we avoid reinventing processes for each engagement. Instead, we tap into a robust collection of proven resources, such as diagnostic tools, templates, platforms, and reference architectures, to quickly assess challenges, propose targeted interventions, and measure outcomes in a consistent, scalable manner.
Through this model, we ensure that our clients benefit from best practices and industry insights embedded directly into our consulting assets. This approach streamlines project delivery, reduces the risks associated with bespoke solutions, and provides a faster time-to-value. By focusing on tangible, repeatable methodologies, we also maintain a consistently high standard of quality, enabling us to address a wide range of business needs with maximum impact.
We continuously embed best practices and expertise into tangible assets, that streamline project delivery, reduce risk, and offer clients cost efficiencies and faster time-to-value. It also allows us to maintain a high level of quality and reproducibility across diverse industries and client needs.

PRICING MODEL
We have a predictable, standardized structure for both the scope of work and the intellectual property we bring to the engagement. As a result, clients typically experience greater transparency and can more easily align the cost of an engagement with its expected outcomes. This consistency can influence pricing in a few ways:
Tiered or Subscription Models
We license or grant ongoing access to our proprietary assets, such as platforms, automated assessment tools, or best-practice libraries, on a subscription basis. Clients pay a monthly or annual fee that covers software usage, updates, and limited consulting support hours, with the option to add premium services as needed.
Usage- or Consumption-Based Pricing
When our asset-based solutions include data processing or analytics that scale with usage (e.g., the number of users, volume of data, or frequency of analysis), we charge based on actual consumption. This model is particularly common when proprietary software or platforms drive much of the engagement.
Fixed-Fee or Package-Based
We may bundle our proprietary tools, frameworks, and services into a well-defined package with a clear scope of work. This approach often leads to a more transparent, lump-sum or fixed-fee pricing model, where clients know exactly what they’re getting and how much it will cost from the outset. In the interest of fairness and incentive to encourage timely execution, we define the corresponding effort in maximum number of days and the maximum duration of the project.
Value-Based or Outcome-Based Models
For projects where we can confidently measure ROI and link our contributions directly to improved performance or cost savings, we may negotiate an outcome-based or success-fee arrangement. Under this model, some portion of the consulting fee is contingent upon meeting specific targets (e.g., efficiency gains, revenue increases, or risk reduction).
Many engagements combine elements of the above models. For instance, we might propose a fixed fee for the initial setup and customization of our tools, then shift to a subscription or consumption model for ongoing access and support.
