Case study: Nature-related financial disclosures (TNFD) — a startup-to-enterprise scale story

When the Taskforce on Nature-related Financial Disclosures published its final recommendations in September 2023, fewer than a dozen technology companies worldwide offered dedicated platforms for nature-related risk assessment and reporting. By early 2026, over 60 vendors compete in this space, and the companies that moved earliest face the defining challenge of any emerging compliance category: converting pilot revenue into enterprise-grade, recurring contracts before larger incumbents absorb the market. This case study traces that journey through the experience of firms that built TNFD-aligned products from scratch, examining what worked, what failed, and what the scaling path reveals about the broader nature finance market.

Why It Matters

Nature-related financial risks represent a category that institutional investors and corporate boards largely ignored until regulatory signals made them unavoidable. The World Economic Forum estimated in 2024 that $44 trillion of economic value generation, more than half of global GDP, is moderately or highly dependent on nature and its services. Yet as recently as 2022, fewer than 5% of FTSE 100 companies disclosed nature-related risks in any structured format.

The regulatory landscape shifted rapidly. The UK Financial Conduct Authority announced in 2025 that it expects listed companies to report against the TNFD framework on a comply-or-explain basis starting in 2026. France's Article 29 of its Energy-Climate Law already requires institutional investors to disclose biodiversity impact. The EU Corporate Sustainability Reporting Directive explicitly references TNFD-aligned metrics within its European Sustainability Reporting Standards (ESRS) for biodiversity and ecosystems. Japan became the first G7 country to formally endorse the TNFD recommendations in 2024, with the Financial Services Agency integrating nature-related disclosures into its corporate governance code revisions.

These regulatory mandates created a defined compliance market with predictable demand curves. Companies need to identify nature-related dependencies and impacts, assess materiality across their value chains, and produce disclosures meeting specific reporting standards. Most lack in-house expertise and data infrastructure to do this, creating demand for external platforms, data providers, and advisory services.

The LEAP Approach: Foundational Framework

The TNFD's core methodological contribution is the LEAP approach, a structured process through which organizations identify and assess nature-related issues. LEAP stands for Locate (identifying the interface with nature across direct operations and value chains), Evaluate (assessing dependencies and impacts on nature), Assess (determining material nature-related risks and opportunities), and Prepare (developing disclosure responses and strategy).

Each phase of LEAP requires specific data inputs and analytical capabilities that most organizations do not possess internally. The Locate phase demands geospatial analysis overlaying corporate asset locations and supply chain nodes against biodiversity-sensitive areas, protected zones, and key biodiversity areas. The Evaluate phase requires biophysical models connecting business activities to ecosystem service dependencies such as pollination, water purification, flood protection, and soil fertility. The Assess phase translates biophysical risks into financial terms through scenario analysis. The Prepare phase structures outputs into disclosure-ready formats aligned with TNFD's 14 recommended disclosures across governance, strategy, risk management, and metrics and targets.

This complexity is the product opportunity. Startups that built integrated platforms covering the full LEAP workflow gained an advantage over point solutions addressing only geospatial analysis or only reporting templates.

Early-Stage Product Development

NatureAlpha: Data-First Approach

NatureAlpha, a UK-based startup spun out of the Cambridge Institute for Sustainability Leadership in 2022, exemplifies the data-first approach to TNFD product development. The company built a nature risk scoring engine that combines satellite earth observation data, biodiversity databases (including IUCN Red List, World Database on Key Biodiversity Areas, and Global Forest Watch), and corporate supply chain data to generate asset-level and portfolio-level nature risk ratings.

The initial product targeted asset managers seeking to screen portfolios for nature-related risks ahead of regulatory requirements. NatureAlpha's first commercial contracts, signed in late 2022 with two UK pension funds and one Nordic sovereign wealth fund, were structured as annual data subscriptions priced at GBP 25,000-75,000 depending on portfolio size and analysis depth. Revenue in the first full year of operations reached approximately GBP 400,000.

Product-market fit emerged through a specific insight: institutional investors needed nature risk data that could be integrated into existing portfolio management and ESG screening workflows, not standalone platforms requiring separate login credentials and analysis processes. NatureAlpha's decision to deliver data through APIs compatible with Bloomberg Terminal, FactSet, and MSCI ESG Manager proved critical to early adoption. Investors could view nature risk scores alongside existing ESG metrics without changing their analytical infrastructure.

Iceberg Data Lab: Biodiversity Footprinting

Iceberg Data Lab, a Paris-based fintech, took a complementary approach by building Corporate Biodiversity Footprint (CBF) metrics that quantify the biodiversity impact of companies using a scientifically grounded methodology based on pressures including land use, climate change, pollution, and resource exploitation. Their CBF metric, expressed in square kilometers of mean species abundance (km2.MSA), provides a single quantitative indicator comparable across sectors and geographies.

Iceberg's early go-to-market strategy focused on French institutional investors subject to Article 29 biodiversity disclosure requirements. This regulatory mandate created a clearly defined buyer with a compliance deadline, eliminating the need to convince prospects of the value proposition. Initial contracts with BNP Paribas Asset Management, AXA Investment Managers, and Sycomore Asset Management established credibility and provided reference customers that accelerated sales across European markets.

The company raised EUR 5 million in Series A funding in 2023, followed by EUR 15 million in Series B in 2025, led by Eurazeo and Demeter Partners. Revenue grew from approximately EUR 1.5 million in 2023 to EUR 8 million in 2025, with the customer base expanding from 35 to over 180 institutional clients.

Scaling Challenges

Data Gaps in Supply Chain Biodiversity Assessment

The most significant operational challenge for TNFD platform companies has been data availability for supply chain nature risk assessment. While direct operations can be assessed using facility coordinates and satellite data, supply chain analysis requires knowledge of where Tier 1, 2, and 3 suppliers operate, what raw materials they source, and from which specific geographies.

NatureAlpha found that even large multinational corporations could identify specific locations for only 40-60% of their supply chain spending. The remainder was allocated to broad geographic categories ("sourced from Southeast Asia") or entirely unknown. This forced the development of probabilistic supply chain models that estimate likely sourcing locations based on trade flow data, commodity production statistics, and industry benchmarks.

These models introduce significant uncertainty. NatureAlpha's internal validation found that probabilistic supply chain assessments achieved 60-70% accuracy at the country level and only 30-40% accuracy at the subnational level, compared to assessments based on known supplier locations. The company addressed this through transparent uncertainty reporting, providing confidence intervals alongside risk scores rather than presenting modeled estimates as precise measurements.

Enterprise Sales Cycle Length

Startups entering TNFD compliance discovered enterprise sales cycles of 9-18 months, substantially longer than anticipated. Several factors drive this extended timeline. Procurement decisions for compliance tools require sign-off from sustainability, legal, risk, and IT departments. Budget allocation for nature-related compliance often falls between existing line items, requiring new budget justification. Many prospective clients initiated competitive evaluation processes comparing 5-8 vendors, extending decision timelines.

Iceberg Data Lab addressed this by offering pilot engagements of EUR 15,000-30,000 covering a limited portfolio assessment, designed to demonstrate value within 60-90 days and convert to full enterprise contracts. Their pilot-to-enterprise conversion rate reached 72% by 2025, validating the land-and-expand model for this market.

Methodology Competition and Standardization

The absence of a single mandated methodology for biodiversity measurement created fragmentation that complicated sales processes. Prospective clients frequently asked which methodology regulators would ultimately endorse, a question no vendor could definitively answer. NatureAlpha, Iceberg Data Lab, and competitors including Align and CDC Biodiversite each used different measurement frameworks with different underlying models, producing non-comparable outputs.

The TNFD secretariat's decision in 2024 to recommend multiple accepted measurement approaches rather than endorsing a single standard both legitimized diverse methodologies and perpetuated buyer confusion. Companies that navigated this most effectively offered methodology-agnostic platforms capable of generating outputs aligned with multiple frameworks, allowing clients to produce disclosures regardless of which standard gained regulatory preference.

Enterprise-Scale Operations

Integration with Existing ESG Infrastructure

The transition from standalone nature risk product to enterprise compliance platform required deep integration with existing corporate ESG and sustainability reporting infrastructure. Enterprise clients operating under CSRD, TCFD, and ISSB frameworks needed nature-related disclosures produced within the same workflow and data architecture used for climate disclosures.

NatureAlpha responded by partnering with established sustainability reporting platforms including Workiva, Persefoni, and Watershed, embedding nature risk data into broader ESG disclosure workflows. This partnership strategy proved more effective than attempting to become a full-spectrum ESG platform. Revenue from integration partnerships represented 35% of NatureAlpha's 2025 revenue, growing to an estimated 50% in 2026.

Iceberg Data Lab took a similar approach with financial data infrastructure, integrating CBF metrics into Sustainalytics, ISS ESG, and S&P Global data feeds. This allowed asset managers to consume biodiversity data through existing vendor relationships rather than onboarding a new data provider.

Pricing Evolution

Pricing models evolved significantly as the market matured. Early contracts were structured as fixed-fee annual subscriptions, but enterprise clients increasingly demanded usage-based or outcome-based pricing. NatureAlpha shifted to a tiered model based on number of assets assessed, with per-asset pricing declining at volume thresholds. Enterprise contracts in 2025 ranged from GBP 50,000 for single-portfolio assessments to GBP 500,000+ for multi-asset-class, global portfolio coverage with API access.

Iceberg Data Lab maintained per-company-assessed pricing, charging EUR 50-150 per company per year for CBF data, with minimum annual commitments. This granular pricing model enabled clients to start with limited coverage and expand organically, supporting the land-and-expand strategy.

FAQ

Q: How long does a full TNFD-aligned assessment take for a large enterprise? A: Plan for 6-12 months for the initial assessment cycle, with subsequent annual updates requiring 2-4 months. The Locate phase typically takes 2-3 months (mapping asset and supply chain interfaces with nature), Evaluate takes 2-4 months (assessing dependencies and impacts), Assess takes 1-2 months (financial materiality determination), and Prepare takes 1-2 months (structuring disclosures). Organizations with existing TCFD processes and comprehensive supply chain data can compress timelines to 3-6 months by leveraging existing governance structures and data infrastructure.

Q: What does a TNFD compliance platform cost for a mid-size financial institution? A: Annual platform costs range from GBP 50,000-200,000 depending on portfolio complexity, number of assets assessed, and depth of supply chain analysis. Additional costs include internal staff time (typically 0.5-2 FTE for ongoing management), advisory support for methodology interpretation (GBP 25,000-75,000), and potential data licensing fees for supplementary datasets. Total first-year cost of compliance for a mid-size UK asset manager typically falls between GBP 150,000-400,000.

Q: Which regulatory framework should companies prioritize if they operate across multiple jurisdictions? A: Build your nature-related disclosure around the TNFD framework as the base layer, as it has been explicitly referenced or endorsed by the UK FCA, Japan FSA, and the ISSB. The EU CSRD's ESRS E4 biodiversity standard has significant overlap with TNFD but includes additional requirements around biodiversity-related targets and transition plans. A TNFD-aligned assessment covers approximately 70-80% of ESRS E4 requirements, making it an efficient starting point for multi-jurisdictional compliance.

Q: How reliable is supply chain nature risk data when supplier locations are unknown? A: Probabilistic supply chain models achieve 60-70% accuracy at the country level and 30-40% at the subnational level. This is sufficient for portfolio-level screening and materiality assessment but inadequate for asset-level risk management or site-specific due diligence. Organizations should use modeled data for initial prioritization, then invest in primary data collection for the highest-risk supply chain segments identified through screening. Transparent reporting of data quality and confidence levels is essential for credible disclosure.

Q: What differentiates startups that successfully scaled in TNFD from those that did not? A: Three factors consistently separated successful scalers. First, integration into existing analytical infrastructure (Bloomberg, FactSet, ESG platforms) rather than requiring standalone platform adoption. Second, regulation-driven go-to-market targeting buyers with compliance deadlines rather than relying on voluntary adoption. Third, pilot engagement structures that demonstrated value within 60-90 days and converted at rates above 60%. Companies that built standalone platforms, targeted voluntary early adopters, or required 6+ month evaluation cycles before demonstrating value consistently underperformed.
