The Complete Guide to Space Industry Due Diligence

Evaluating a space company is fundamentally different from evaluating a SaaS startup or a traditional manufacturer. The capital intensity is higher, the regulatory landscape is more complex, the technology risk is more severe, and the timelines to revenue are often measured in years rather than quarters. Yet the tools and frameworks available for space industry due diligence have historically lagged far behind other sectors.

This guide provides a structured approach to evaluating space companies using publicly available data, proprietary intelligence from SpaceNexus company profiles, and the SpaceNexus Score — our composite rating that distills six critical dimensions of company health into a single, actionable metric.

Why Space Due Diligence Is Different

Before diving into methodology, it is worth understanding why standard due diligence frameworks fall short when applied to space companies.

Capital intensity. Developing a launch vehicle costs $500 million to $2 billion. Building a satellite constellation can cost $1-10 billion. These are not software companies where a small team can reach product-market fit on a seed round. The capital requirements shape everything — from burn rates to funding strategy to exit timelines.

Regulatory dependency. Space companies need licenses from the FAA (launch), FCC (spectrum), NOAA (remote sensing), and potentially DDTC (export controls). A single regulatory delay can push a launch by months and burn through tens of millions in carrying costs. Understanding a company's regulatory posture is not optional — it is existential.

Technical risk concentration. A rocket either works or it does not. A satellite either reaches orbit or it does not. Binary technical outcomes create a risk profile that is fundamentally different from incremental software development. Due diligence must assess technical readiness with rigor.

Long feedback loops. It can take 3-5 years from company founding to first orbital test. Revenue may not materialize for 5-8 years. Traditional metrics like ARR growth and customer acquisition cost are often irrelevant for pre-revenue space companies.

The Six Dimensions of Space Company Evaluation

At SpaceNexus, we evaluate space companies across six dimensions, each scored from 0-100 and weighted to produce the composite SpaceNexus Score:

1. Financial Health (Weight: 20%)

Financial health assesses a company's ability to survive long enough to execute its business plan. Key indicators include:

• Cash runway: How many months of operating expenses can the company cover with current cash reserves? For pre-revenue space companies, 18+ months of runway is the minimum threshold for comfort.
• Funding history: Track the progression of funding rounds using the SpaceNexus Funding Tracker. Look for increasing round sizes from credible investors. Down rounds or bridge financing are red flags.
• Revenue trajectory: For companies with revenue, assess growth rate, customer concentration, and contract backlog. Government contracts provide revenue visibility but often come with margin compression.
• Capital efficiency: How much capital has the company raised relative to the milestones achieved? Compare against sector benchmarks — a launch company that has raised $500 million without reaching orbit faces harder questions than one that has reached orbit on $200 million.

Data sources: SEC filings (10-K, 10-Q, S-1 for public companies), Crunchbase, PitchBook, and the SpaceNexus Funding Tracker which aggregates funding data for 200+ space companies.

2. Technology Readiness (Weight: 20%)

Technology readiness evaluates where a company's core technology sits on the development spectrum and the credibility of its technical claims.

• TRL assessment: NASA's Technology Readiness Level (TRL) scale (1-9) provides a standardized framework. TRL 1-3 is basic research. TRL 4-6 is development and testing. TRL 7-9 is flight-proven. Ask: what TRL is the core technology, and what evidence supports that claim?
• Patent portfolio: Review patent filings using the SpaceNexus Patent Intelligence module. Patent activity indicates genuine R&D investment and can reveal technical direction. Look for granted patents (not just applications) and assess whether the IP is core to the business model.
• Test and launch track record: For launch providers, examine success rates, cadence improvement, and anomaly resolution. For satellite operators, assess on-orbit performance, mission life vs. design life, and failure rates.
• Technical team credentials: Evaluate the depth of the engineering team. Key hires from SpaceX, Blue Origin, JPL, or major aerospace primes signal technical credibility. Check the Executive Moves tracker for recent leadership changes.

3. Market Position (Weight: 15%)

Market position evaluates competitive dynamics and the company's ability to capture market share.

• Addressable market: Is the company targeting a market that is large enough and growing fast enough to support a venture-scale outcome? Use the SpaceNexus Market Intelligence module for market sizing data.
• Competitive landscape: Who are the direct and indirect competitors? What is the company's differentiation — cost, performance, reliability, time-to-market?
• Customer validation: Has the company secured contracts, letters of intent, or partnerships with credible customers? Government anchor contracts (e.g., NASA CLPS, Space Force SDA Tranche) provide strong validation.
• Backlog and pipeline: What is the contracted backlog value relative to the company's annual capacity? A healthy backlog-to-capacity ratio indicates demand sustainability.

4. Growth Momentum (Weight: 15%)

Growth momentum captures the trajectory of key business metrics over the most recent 6-12 months.

• Contract wins: Track new contract announcements and compare year-over-year. The SpaceNexus Deal Flow module aggregates this data across the industry.
• Headcount growth: Hiring velocity, particularly in engineering roles, signals confidence in the business plan and adequacy of funding.
• Launch or deployment cadence: For operational companies, increasing cadence indicates scaling capability.
• Partnership expansion: New strategic partnerships, especially with larger aerospace primes or government agencies, indicate growing industry credibility.

5. Operational Maturity (Weight: 15%)

Operational maturity assesses whether a company can execute reliably at scale.

• Manufacturing capability: Can the company produce hardware at the rate its business plan requires? Transitioning from prototype to production is one of the most common failure points in hardware-intensive space companies.
• Supply chain resilience: Assess dependency on single-source suppliers, particularly for critical components like propulsion systems, avionics, and solar cells.
• Quality and compliance: AS9100 certification, NASA suitability assessments, and ITAR/EAR compliance programs indicate operational seriousness.
• Organizational depth: Does the company have functional leadership beyond the founders? VP-level hires in operations, finance, and business development signal maturation.

6. Risk Profile (Weight: 15%)

Risk profile identifies factors that could derail execution regardless of the company's other strengths.

• Key person dependency: Is the company overly dependent on a single founder, engineer, or customer?
• Regulatory risk: Are there pending regulatory decisions that could materially affect the business?
• Geopolitical exposure: Does the company have supply chain or customer dependencies in geopolitically sensitive regions?
• Litigation and IP disputes: Active or pending lawsuits can drain resources and create uncertainty.

Practical Due Diligence Workflow

Here is a step-by-step workflow for conducting space company due diligence using SpaceNexus:

1. Start with the company profile: Visit Company Profiles and review the company's SpaceNexus Score, financial summary, satellite assets, contract history, and patent portfolio — all in one place.
2. Review funding history: Use the Funding Tracker to map the company's fundraising trajectory, investor quality, and implied valuation progression.
3. Assess technical credibility: Check the Patent Intelligence module for IP activity and review launch/mission history from public records.
4. Map competitive dynamics: Use SpaceNexus market data to understand where the company sits relative to competitors in its segment.
5. Monitor ongoing activity: Set up alerts for the company's news mentions, contract wins, executive moves, and regulatory filings.
6. Synthesize and score: Use the six-dimension framework above to create a structured assessment, or leverage the SpaceNexus Score as a starting point for deeper analysis.

Common Red Flags in Space Company Evaluation

Years of analyzing space companies have taught us to watch for these warning signs:

• Timeline slippage without explanation: Missed milestones happen in space. But chronic slippage without transparent communication suggests systemic execution problems.
• Revenue projections disconnected from backlog: Be skeptical of hockey-stick revenue projections that are not supported by contracted backlog or letters of intent.
• Over-reliance on a single customer or contract: Customer concentration above 40% creates fragility, especially if that customer is a government agency subject to budget cycles.
• Frequent leadership turnover: Track executive moves using the SpaceNexus Executive Moves tracker. High turnover in VP-level engineering or operations roles is concerning.
• Vague technical claims: Companies that market capabilities they have not demonstrated or use qualitative language instead of quantitative metrics deserve extra scrutiny.
