What Preoptima does
Preoptima Ltd is a London-based climate technology company founded in 2023 by academic researchers Francesco Pomponi (CEO/CSO), Lorenzo Coccia (CTO), and Jay Arehart (Head of Product), whose combined work in embodied and whole life carbon has been cited more than 6,000 times globally. The company provides AI-powered whole life carbon (WLC) assessment software for the built environment through two integrated SaaS products. CONCEPT targets architects, engineers, developers, and sustainability consultants with real-time carbon optioneering, generative structural design, and automated material quantity take-offs from imported .obj massing models, reducing assessment lead times from weeks to minutes. PACER is a centralised compliance review platform for local planning authorities, developed in collaboration with Westminster City Council and being validated under the government-funded CLEAR project with the London Borough of Tower Hamlets and the City of London Corporation. A WholeLifeCarbon API extends the underlying calculation engine to third-party BIM and design software.
Preoptima generates revenue through SaaS subscriptions for CONCEPT (offered on a freemium model with a free trial), government and authority licensing for PACER, and API licensing. Its go-to-market combines product-led self-serve acquisition with enterprise distribution via the Nemetschek Group ecosystem, including a flagship embedded integration with ALLPLAN's 2026 BIM releases. The customer base spans industry professionals (with named users including Foster + Partners, Maccreanor Lavington, and Group14 Engineering) and UK local authorities, anchored by a £1 million pre-seed round in March 2023 led by Nemetschek with Nomea Investments, Climate VC, and Carbon13. The company operates with a six-person team from a registered office in Covent Garden, London.

Preoptima product offering
Product offeringCore offering
Preoptima provides an AI-powered whole life carbon (WLC) assessment platform for the built environment, delivered through two core products: CONCEPT, a SaaS tool for architects, engineers, developers, and consultants to perform real-time carbon optioneering and generative design comparisons during early-stage concept work; and PACER, a centralised portal for UK local planning authorities to manage, validate, and review whole life carbon assessments submitted with planning applications.
Product overview
Preoptima provides two integrated SaaS products for whole life carbon management in the built environment. CONCEPT serves architects, engineers, developers, and consultants for early-stage carbon optioneering and design optimization. PACER serves local planning authorities for compliance review and carbon tracking in planning submissions. The two products are architected for future integration, enabling industry professionals to perform assessments in CONCEPT and seamlessly submit them to PACER for planning approval.

Preoptima competitors and assessment
Company assessmentDirect peers
- One Click LCA: One Click LCA is a leading SaaS platform for life cycle assessment and embodied carbon calculations across the built environment, serving architects, engineers, and developers with a similar product surface to Preoptima CONCEPT and competing directly for the same sustainability consultant and design firm buyers.
- Building Transparency (EC3): Building Transparency operates the Embodied Carbon in Construction Calculator (EC3), a free, widely adopted tool for embodied carbon assessment of construction materials. It is the dominant open alternative to Preoptima CONCEPT for EPD-based carbon estimation and shares the same architect/specifier buyer base.
- Tally (KT Innovations / Autodesk): Tally is a Revit-integrated LCA plugin for whole-building life cycle assessment, now distributed by Autodesk. It is the most widely deployed Revit-native embodied carbon tool and directly competes with Preoptima CONCEPT inside the same BIM authoring environment, but is bundled with Autodesk subscriptions.
- eTool: eTool is a SaaS platform for LCA and embodied carbon assessment targeting architects, engineers, and project owners. It overlaps with Preoptima CONCEPT on early-stage design carbon optioneering and shares similar building certification and regulatory positioning in the UK/AU markets.
Emerging players
- Briq: Briq is a construction financial planning and analytics platform that has expanded into carbon and sustainability metrics for general contractors and project owners. It overlaps with Preoptima on the data-driven sustainability reporting layer for the built environment, though its primary wedge is financial forecasting rather than early-stage design carbon optioneering.
- CarbonCure: CarbonCure provides carbon-sequestering concrete technology and a sustainability data platform for the construction materials supply chain. It overlaps with Preoptima in the embodied carbon ecosystem but is a materials-side player rather than a design-stage optioneering tool.
- Measurabl: Measurabl is an ESG and carbon data management platform for real estate portfolios, addressing carbon tracking and disclosure for property owners and investors. It overlaps with Preoptima's portfolio/property investor segment but focuses on operational rather than embodied carbon.
- Cobuilder: Cobuilder provides structured product data and digital material passports for the construction industry, including sustainability and carbon-relevant data. It overlaps with Preoptima on the data backbone of embodied carbon assessment and is increasingly relevant as the EU moves toward digital product passport requirements.
Broad incumbents
- IES (Integrated Environmental Solutions): IES provides a broad building performance simulation suite covering energy, daylighting, and embodied carbon (IES LCA). It is a much larger, established player in the AEC sustainability software market and competes with Preoptima CONCEPT in whole-building sustainability assessment, though its focus is more on operational than embodied carbon.
- Sphera: Sphera is an enterprise ESG and product sustainability platform with LCA and carbon accounting capabilities that extend into the built environment. It is a broad incumbent competing with Preoptima on corporate/portfolio-level carbon reporting rather than concept-stage architect workflows.
