ToffeeX is a UK-based deep-tech startup that specializes in generative design for thermal-fluid components. Spun out of Imperial College London in 2019, ToffeeX is redefining how industrial parts like heat exchangers and cold plates are designed—bringing speed, efficiency, and manufacturability to the forefront.
At its core, ToffeeX offers a cloud-native platform that uses physics-based algorithms to generate high-performance component designs tailored to real-world manufacturing constraints. By doing so, it empowers industries such as aerospace, automotive, energy, and electronics to reduce development cycles and unlock performance gains that were previously difficult to achieve.
Founders and Origins
ToffeeX was co-founded by:
- Marco Pietropaoli – CEO and engineering innovator with a PhD in fluid dynamics from Imperial College London.
- Francesco Montomoli – CSO and professor of computational aerodynamics, also at Imperial College.
The duo combined academic excellence with commercial ambition to transform years of fluid dynamics and topology optimization research into a practical tool that industries can use at scale.
Core Product Offering
ToffeeX’s flagship offering is its physics-driven generative design platform, which is built specifically to solve thermal and fluid design challenges. The software uses a combination of simulation, optimization, and manufacturing constraints to produce high-performance part geometries within a matter of hours.
Key Features:
- End-to-End Automation: From input specifications to manufacturable CAD outputs.
- Thermal and Flow Optimization: Designs are generated to enhance cooling efficiency, reduce pressure drops, or minimize weight.
- Manufacturing Compatibility: Outputs are tailored for various manufacturing methods including 3D printing (AM), CNC machining, chemical etching, and stamping.
- Cloud-Based Platform: Accessible globally and scalable for enterprise teams.
This product is particularly useful for engineering teams designing components such as:
- Heat exchangers
- Cold plates
- Fuel manifolds
- Liquid and air cooling systems
- Internal flow devices in high-performance applications
Use Case Highlight: Thermal Optimization with Ricoh
ToffeeX collaborated with Ricoh to enhance the performance of cooling components through additive manufacturing.
Challenge:
Ricoh needed to improve the thermal efficiency of heat sinks while reducing material use and simplifying production complexity.
Solution:
Using ToffeeX’s generative design engine, Ricoh engineers were able to:
- Decrease pressure drop by 68%
- Improve thermal performance by over 30%
- Cut down design iteration time significantly
The resulting parts were optimized for Ricoh’s binder-jetting 3D printing process, validating the platform’s strength in both design quality and manufacturability.
Business Model
ToffeeX operates on a hybrid B2B model that blends software licensing with consultative services.
Key Revenue Streams:
- SaaS Licensing – Engineering teams subscribe to the cloud-based platform to generate designs independently.
- Design-as-a-Service (DaaS) – ToffeeX provides expert-led optimization projects for companies needing tailored design work.
- Partnership Programs – Joint development initiatives with manufacturers and research labs expand the platform’s footprint.
- Custom Integrations – Enterprise clients can request specific tooling or workflow integrations for large-scale deployment.
This business model allows ToffeeX to cater to both agile startups and large enterprises looking for efficient design solutions.
Revenue Model
The company earns revenue through a mix of:
- Annual or monthly subscription fees
- Pay-per-design credits or compute usage
- Bespoke engineering consultation fees
- Collaborative R&D project funding with industry partners
This diversified model supports recurring revenue while enabling flexibility in service delivery.
