Financial DD asks: is this a good investment? Technical DD asks: does the technology work? Structural DD asks the question nobody else is asking: can this organisation convert the capital into the outcomes the thesis describes? The market can be real. The technology can be validated. The team can be talented. And the company can still fail because the organisational structure that connects the technology to the market was never assessed. Structural DD is the framework for that assessment.
The layer that standard DD doesn’t evaluate
Standard DD evaluates the market (is there demand?), the technology (does it work?), and the team (are they credible?). Each layer has established methodologies, specialist evaluators, and decades of practice behind it. The structural layer — the decision architecture, authority distribution, cadence alignment, and scaling readiness of the organisation — has none of these. It’s the layer that determines whether the other three layers produce outcomes, and it’s the one your process skips.
Katerra raised roughly $2B with market validation, technology validation, and team credentials that passed every standard DD check. The organisation that was supposed to coordinate vertical integration across factories, design studios, construction sites, and a technology platform was structurally incapable of it. June 2021 shutdown. Northvolt’s November 2024 Chapter 11 — $5.8B in debt, roughly $30M in cash — came after the battery technology was validated, the offtake book was signed, and the team included experienced automotive and energy executives. The gigafactory’s organisational capacity to convert capex into production at the required cadence was the structural failure. Standard DD evaluated the technology and the market. Nobody evaluated the operating model.
The structural DD framework: four assessments, two weeks
The framework evaluates four structural dimensions that predict whether the organisation can deliver on the thesis:
1. Decision graph mapping. How do cross-functional decisions actually get made? Not the org chart — the real path a significant decision takes from initiation to implementation. In climate tech companies running four operating models simultaneously, decision latency at the cross-functional seams is where execution speed is structurally determined. The assessment maps the top twenty decision types: who initiates, who decides, who executes, how long each step takes, and where the formal and informal authority structures contradict each other.
2. Founder-organisation fit. Not whether the founder is capable, but whether the organisational design lets the founder operate at the level the company now requires. A founder who appears unable to delegate may be making a rational choice in a system where no one else has the authority, context, or information to decide well. The assessment distinguishes structural constraints from personal ones — because the intervention for each is different.
3. Scaling readiness. If the thesis requires the company to go from 30 to 80 people in eighteen months, does the organisational infrastructure for that transition exist? The assessment evaluates whether the company has passed or is approaching a scaling breakpoint, and whether the current operating model can support the next stage without a structural redesign. In climate tech, breakpoints hit at lower headcounts than in SaaS because the coordination load per person is higher.
4. Cadence alignment. Does the company’s operating cadence match its commercial cadence? Hardware development on years, software on weeks, government procurement on its own cycle — and the commercial market on whatever timeline the customer dictates. If these cadences aren’t reconciled in the decision architecture, the company runs on the slowest cadence applied to all of them, regardless of how fast any individual function can move.
The output is conditions, not judgment
Structural DD produces a risk profile with specific mechanisms and conditional interventions — not a verdict on the team. The output format:
“The decision graph routes cross-functional decisions through the founder. Decision latency from initiation to implementation averages three weeks on decisions that should take three days. If the thesis requires commercial scaling from €5M to €30M in three years, this architecture will cap the company’s throughput. Condition: redistribute decision authority for product, pricing, and customer commitments before the capital deployment plan activates.”
For pre-investment: the conditions either attach to the term sheet or inform the decline. For post-investment: the same assessment becomes a portfolio diagnosis with redesign interventions. The method is the same — Observe, Hypothesise, Test, Revise. The depth and timeline change.
Why climate tech requires structural DD more than software
Software DD processes were built for companies with one operating model and one cadence. The decision graph is simpler. The founder transition is less acute because the founder’s technical depth is more replaceable. The scaling breakpoints are more predictable because the coordination load grows linearly with headcount rather than multiplicatively with operating model count.
Climate tech breaks these assumptions. Carbon removal companies run three operating cadences simultaneously — research on weeks, manufacturing on quarters, project development on years. Earth observation companies run four operating models with incompatible authority structures. Climate insurance companies combine actuarial conservatism with climate model innovation in a single decision architecture. Each of these creates structural risk that software-origin DD frameworks cannot see because they were never designed to look for it.
The structural DD framework is the missing layer. It sits between financial DD (which evaluates the opportunity) and technical DD (which evaluates the technology) and asks the question that determines whether either matters: can this organisation deliver?
The structural layer is where your capital either converts into the outcomes your thesis described, or quietly doesn’t. Run the two-week structural DD on the next deal.
