Materials
Rare earth separation capacity exists. Offtake commitments do not.
DPA Title III can start capacity; only purchase commitments make it permanent.
Frontier capability / Sovereign constraint
The people who speak both stack and state will define the next decade.
Stack & State is the publication and connective layer for bilingual architects: founders, investors, strategics, and public operators who can translate product, capital, procurement, and policy into the same map.

Walter Guevara, INSEAD MBA, is the founder of Stack & State. He writes on the DMV gov-tech and capital ecosystem, operating as a bilingual architect between Silicon Valley and Washington DC.
Built the Bottleneck Map methodology, tracking 25 constraints across 10 layers of the sovereign technology ecosystem.
Operates at the SV-DC nexus: translates between technology roadmaps, institutional architecture, and the capital stacks that connect them.
Bottleneck Map
The map is the product.
Sovereign technology does not fail because actors are absent. It fails because founders, capital, buyers, and regulators cannot see each other's constraints in time. The Bottleneck Map tracks where these failures concentrate.
Evaluation
Government buyers evaluate AI systems without technical evaluation capacity.
Large procurements can be difficult for program offices to evaluate independently.
Diligence
CVCs cannot diligence dual-use technology at the depth the market requires.
Corporate venture can be a bridge when diligence covers both technology and policy risk.
Translation
Founders build into regulatory frameworks they cannot read.
Late regulatory discovery can force expensive product and market-access changes.
Capital
Sovereign capital deploys into strategic tech without layer-specific diligence.
Strategic technology allocations often require technical diligence outside a generalist investment process.
Offtake
Public capital starts capacity. Offtake determines whether it survives.
The bridge between policy and production is a purchase commitment.
The first front
Critical minerals and sovereign materials.
We start with the base layer: rare earths, advanced alloys, battery minerals, processing capacity, offtake, and the public-private capital now reshaping materials supply chains. It is the first front, not the whole brand.
Tracked
Public commitments (source-reviewed)
Programs, awards, and allied industrial-policy signals around materials capacity.
Fragmented
Coverage
Policy papers, trade data, company updates, and investor signals rarely meet in one builder-readable brief.
Base
Layer dependency
Autonomy, energy, compute, advanced manufacturing, and undersea systems all depend on materials capacity.
What the briefing gives you
One week of signal, reduced to the decisions that change a roadmap.
01 / Map
One market map
The companies, programs, bottlenecks, and National Capital Region relationships that matter.
02 / Capital
One capital signal
Where federal, allied, corporate, strategic, or sovereign money is moving before consensus catches up.
03 / Constraint
One policy constraint
The procurement rule, export-control issue, permitting barrier, CFIUS risk, or OTA/SBIR path builders need to understand.
04 / Intro
One introduction thesis
Who should be talking to whom across DC, Northern Virginia, primes, founders, labs, and strategic buyers.
Signals we track
Three patterns visible before consensus catches up.
Built from government awards, procurement databases, company filings, permitting records, and trade data.
Processing over mining
China's mineral leverage is moving from mining to processing.
The map that matters is separation, refining, offtake, and permits.
Public capital without offtake
Why DPA Title III money is not enough without offtake.
Public capital can start capacity. Strategic demand decides whether it survives.
Materials behind autonomy, reactors, compute, and grid hardware
The materials bottleneck behind sovereign technology.
Magnets, alloys, graphite, uranium fuel, and grid hardware turn sovereignty into a bill of materials.
Featured analysis
Builder-readable maps of the sovereign technology landscape.
Published pieces are reviewed for structure and clarity. Primary-source verification is ongoing.
Flagship briefing
The Materials Bottleneck Behind Sovereign Technology
Why processing, not mining, is the real constraint - and who needs to meet whom to solve it.
Export controls
The Complete Guide to Export Controls for Deep-Tech Startups
A builder-readable map of ITAR, EAR, CFIUS, product architecture, and fundraising risk.
Non-dilutive capital
Non-Dilutive Capital for Defense Tech
Every program, decision tree, and transition strategy for founders navigating government funding.
Procurement
SBIR vs. STTR: Which Program, Which Agency, and How to Choose
A decision tree for founders choosing between research partnerships and government-funded prototypes.
Sovereign tech
Sovereign AI Explained
How compute, cloud, and model provenance decisions determine market access and procurement eligibility.
Ecosystem
Who needs whom.
Stack & State tracks the people, programs, companies, capital pools, and constraints shaping sovereign technology markets. The briefing explains what changed. The map shows who needs whom.
Materials
Critical minerals bottlenecks
Processing, separation, offtake, and permitting - the base layer of sovereign technology capacity.
Programs
Government procurement and non-dilutive capital
SBIR, DIU, DARPA, DPA Title III, OSC, DOE LPO - the programs that turn prototypes into production.
Capital
Strategic, corporate, and sovereign capital
CVCs, sovereign wealth funds, development finance, and allied industrial policy - who is deploying where.
Constraints
Export controls and compliance
ITAR, EAR, CFIUS, entity-list screening - the regulatory architecture that shapes product roadmaps.
Gaps
Founder-to-buyer disconnects
The missing links between builders who have technology and government buyers who need it.
Allied
Allied capital and industrial capacity
AUKUS, NATO Innovation Fund, European Defence Fund, and allied supply-chain coordination.
How we work
Editorial standards for a market that requires verifiable independence.
Independent analysis
Editorial judgment is based on source material, market relevance, and operator usefulness.
No paid coverage
Companies, sponsors, members, and investors cannot buy editorial placement.
Labeled sponsorship
Sponsored research, events, or partner work are identified clearly.
Separated introductions
Membership and intro access are separate from editorial selection and criticism.
Who this is for
Founders
Regulatory translation, procurement navigation, non-dilutive capital mapping, and the connective tissue between your product and the buyers who need it.
Investors and CVCs
Curated ecosystem intelligence, policy-risk assessment, deal-flow signal, and visibility into where public capital is creating private opportunity.
Government buyers
Technical market signal, qualified company pipelines, and translation between what is being built and what procurement can buy.
Capital allocators
Sovereign technology market mapping, technical due diligence frameworks, and visibility into the companies and programs that match allocation mandates.
