What Is the STACK Note™ ?
A Structured Venture Note
A Structured Venture Note is a hybrid capital instrument designed to bridge the gap between early-stage venture funding and later-stage structured capital.
It combines elements of:
Convertible instruments (such as SAFEs and convertible notes)
Priced equity rounds
Structured finance mechanisms typically seen in private credit and growth capital
The result is a capital structure that allows investors to deploy capital with defined downside protection and controlled upside participation, while enabling companies to raise at Seed and post-Seed stages without relying solely on traditional venture equity rounds.
A Structured Venture Note does not operate as a simple deferred equity agreement. It is designed as a layered instrument, where return, conversion, and control are explicitly modelled at entry rather than left to future negotiation.
Why Structured Venture Notes (STACK Notes) Exist
Traditional early-stage instruments were designed for speed, not precision.
SAFEs prioritise simplicity but defer pricing tension
Convertible notes introduce debt features but remain structurally light
Equity rounds impose valuation discipline but require full institutional readiness
This creates a gap at Seed and early growth stages where:
Companies have progressed beyond idea-stage risk
Investors require more structured exposure
Full institutional rounds are premature or inefficient
A Structured Venture Note addresses this gap by introducing:
Defined economic participation
Structured conversion mechanics
Pre-agreed capital stack positioning
It allows capital to be deployed into companies that are no longer speculative, but not yet institutionally priced.
Core Structural Components
A Structured Venture Note typically includes the following elements:
1. Defined Entry Valuation Framework
Rather than relying on open-ended future pricing, the note establishes:
A valuation cap or range
Discount mechanics (if applicable)
Scenario-based conversion outcomes
This reduces pricing ambiguity and aligns investor expectations upfront.
2. Layered Return Structure
Unlike traditional venture instruments that rely entirely on exit outcomes, Structured Venture Notes can include:
Fixed return components (yield or minimum return thresholds)
Variable equity upside participation
Conversion-linked performance triggers
This creates a dual exposure:
Downside protection through structured return
Upside participation through equity conversion
3. Conditional Conversion Mechanics
Conversion into equity is not always automatic or singular.
Structured Venture Notes may include:
Milestone-based conversion triggers
Time-based conversion windows
Event-driven conversion (e.g., qualified financing, revenue thresholds, liquidity events)
This allows capital to convert based on actual company progression rather than arbitrary timing.
4. Capital Stack Positioning
The note is explicitly positioned within the company’s capital structure.
This includes:
Seniority relative to future investors
Interaction with existing instruments (SAFEs, notes, equity)
Dilution pathways under different scenarios
This clarity removes ambiguity around ownership outcomes and investor rights.
5. Governance and Control Provisions
Depending on structure, the note may include:
Information rights
Consent rights on major decisions
Structured oversight mechanisms
These are calibrated to reflect the company’s stage and the size of capital deployed.
How a STACK Note Applies This Structure
A STACK Note is the proprietary implementation of a Structured Venture Note within the MoonshotNX ecosystem.
It standardises:
Instrument design
Conversion logic
Capital stack integration
Investor participation pathways
This allows structured capital to be deployed consistently across multiple companies while maintaining comparability and discipline.
The STACK Note is designed to integrate directly with:
Capital readiness diagnostics
Valuation frameworks
Investor room deployment
SPV-based capital aggregation
It functions as both a capital instrument and a system-level structuring mechanism.
Stage Focus: Seed and Post-Seed Companies
Structured Venture Notes are specifically designed for companies that have moved beyond pre-seed uncertainty but are not yet operating at full institutional scale.
Typical Stage Definition
The instrument is deployed into companies at:
Seed
Late Seed
Early Series A readiness
These are companies where:
Product is built and in market
Initial traction is observable
Capital is required for expansion, not discovery
Minimum Requirements for STACK Note Eligibility
To qualify for a Structured Venture Note, companies must meet defined operational and structural thresholds.
1. Product and Market Validation
The company must demonstrate:
A functioning product in market
Evidence of user adoption or customer engagement
Clear problem-solution alignment
This removes pure concept-stage risk.
2. Traction Signals
While not necessarily scaled, the company must show:
Revenue or credible revenue pathways
User growth or retention indicators
Early unit economics visibility
The emphasis is on observable behaviour, not projections.
3. Capital Readiness
The company must be structurally prepared to receive and deploy capital.
This includes:
Clean cap table
Defined ownership structure
Existing instruments understood and mapped
Ambiguity at the cap table level disqualifies structured deployment.
4. Data Room Completeness
A structured capital instrument requires structured information.
Minimum requirements include:
Financial model or operating plan
Legal documentation (formation, IP, prior agreements)
Commercial and product materials
Incomplete data environments prevent proper structuring.
5. Valuation Framework Alignment
The company must be able to support a defensible valuation range.
This is not based on narrative positioning but on:
Market comparables
Traction benchmarks
Capital requirements
The Structured Venture Note relies on this to define conversion mechanics.
6. Capital Use Clarity
The use of funds must be explicitly defined.
This includes:
Deployment plan
Milestone linkage
Expected impact on growth or valuation
Structured capital requires structured deployment logic.
Investor Perspective
From an investor standpoint, a Structured Venture Note provides:
Greater control over entry conditions
Defined return pathways
Reduced reliance on future pricing negotiations
Visibility into capital stack outcomes
It allows participation in early-stage growth with a level of structure typically reserved for later-stage investments.
Company Perspective
For companies, the instrument enables:
Access to capital without immediate priced rounds
Reduced valuation negotiation friction
Structured alignment with investors
Clear pathways to future institutional rounds
It supports progression rather than forcing premature pricing events.
Position Within the Capital Stack
A Structured Venture Note sits between:
Early-stage flexible instruments (SAFEs, convertible notes)
Fully priced institutional equity rounds
It introduces structure at the point where:
Risk is reduced
Complexity increases
Capital requirements expand
This positioning is what defines its role within modern venture financing.
Summary
A Structured Venture Note is a precision capital instrument designed for companies that have moved beyond early uncertainty but are not yet fully institutionally financed.
The STACK Note formalises this structure into a deployable system:
Standardised
Modelled
Integrated into the broader capital ecosystem
It represents a shift from speed-driven early-stage funding toward structured, outcome-aware capital deployment at Seed and beyond.
The Evolution of Structured Venture Capital
Modern startup financing did not begin with simplicity. It began with structure.
The first institutional venture capital firm, American Research & Development Corporation, was established in 1946. Its model introduced a core principle that still defines venture investing today: capital is deployed into high-growth companies with the expectation of long-term, equity-based returns.
For decades, venture capital followed a relatively rigid structure. Companies raised priced equity rounds, investors received preferred shares, and ownership was determined at each stage through formal valuation processes.
As the cost of building startups declined in the early 2000s, the market began to shift. Founders needed faster access to capital, and investors needed simpler ways to participate earlier in the lifecycle. This led to the rise of convertible notes, which became widely adopted as a bridge instrument. They allowed capital to be deployed quickly, with conversion into equity deferred to a later round.
However, convertible notes introduced their own constraints. As debt instruments, they carried interest, maturity dates, and repayment risk, which did not always align with the realities of early-stage companies.
In response, Y Combinator introduced the SAFE (Simple Agreement for Future Equity) in 2013, removing debt features entirely and simplifying early-stage fundraising into a fast, standardised agreement.
This marked a fundamental shift. Early-stage capital became:
Faster
Simpler
Less structured
But that simplification came at a cost.
As companies matured beyond pre-seed, the limitations of these instruments became increasingly visible:
Pricing was deferred rather than defined
Investor protections were reduced
Capital stack complexity accumulated across multiple rounds
What emerged over the past decade is a new phase in venture financing.
Not a replacement of these instruments, but an evolution beyond them.
The Emergence of Structured Venture Notes
Structured Venture Notes represent the next stage in this progression.
They combine:
The flexibility of early-stage instruments
The discipline of priced equity
The precision of structured finance
While convertible notes and SAFEs have been widely used for over 15 to 20 years in modern startup ecosystems, Structured Venture Notes are a more recent development, emerging alongside the increasing institutionalisation of Seed and post-Seed investing.
They are designed for a different moment in a company’s lifecycle:
A point where:
The business is no longer speculative
Capital requirements are larger and more deliberate
Investors require defined risk and return frameworks
Rather than deferring structure, Structured Venture Notes introduce it at the point of investment.
STACK Note FAQ
What is a STACK Note?
A STACK Note is our proprietary name for a Structured Venture Note. It is the same instrument category, presented under our own branding.
What is a Structured Venture Note?
A Structured Venture Note is a venture investment instrument designed to deploy capital into companies that have moved beyond the earliest stage of formation and are now raising growth capital with more structure around entry, conversion, investor protections, and outcome alignment.
It sits between very early flexible instruments and fully negotiated institutional rounds. It is used where a company has enough maturity, traction, and visibility to support a more structured capital instrument.
Is a STACK Note different from a Structured Venture Note?
No. A STACK Note is a Structured Venture Note. STACK Note is simply our proprietary name for that structure.
Why use the name STACK Note?
The name allows us to identify our own structured venture note framework clearly within our ecosystem, while still using a recognised underlying capital concept. It is a branded term, not a different legal category.
What stage companies is a STACK Note designed for?
A STACK Note is designed for Seed+ companies.
That generally includes businesses at:
Seed
Late Seed
Early Series A readiness
These are companies that have moved beyond concept stage and are raising capital to scale an operating business rather than to test whether the business exists at all.
What does Seed+ mean?
Seed+ refers to companies that are beyond pre-seed or idea-stage risk and have already established the basic foundations of a venture-backable business.
In practical terms, this usually means the company has:
a real product or live offering
evidence of market engagement
a clearer operating structure
a more defined growth plan
a need for capital to expand, not simply to begin
Who is a STACK Note for?
A STACK Note is for companies that are too advanced for purely informal early-stage instruments, but not yet at the point where a full institutional priced round is the right fit.
It is intended for founders who need capital with greater structure and for investors who want clearer terms around participation, conversion, and downside positioning.
What are the minimum requirements for a company to qualify?
To be considered for a STACK Note, a company should generally meet the following requirements:
it must be a Seed+ company
it must have a live product, service, or operational business
it must show market validation or commercial traction
it must have a clear use of funds
it must have a reviewable cap table and corporate structure
it must be able to support diligence review
it must be raising capital for growth, expansion, or execution
Does a company need traction to qualify?
Yes. A STACK Note is not designed for pure concept-stage companies.
A company should be able to show some form of traction, which may include:
revenue
pilot customers
active users
signed contracts
distribution progress
repeatable commercial demand
measurable market validation
The exact threshold will depend on the business model, sector, and stage, but there must be evidence that the company has moved beyond theory.
Does a company need a product in market?
In most cases, yes.
A STACK Note is generally intended for companies with a live product, operational service, or functioning commercial offer. The business should be at a point where capital supports execution and scale, not basic invention alone.
Does a company need a clean cap table?
Yes. A company must have a sufficiently clear and reviewable capital structure.
This includes visibility on:
founder ownership
prior equity issuances
SAFEs or convertible notes, if any
employee option allocations
any other existing rights or instruments that affect future ownership
If the cap table is confused, incomplete, or structurally problematic, the company may not be suitable until that is resolved.
Does a company need a data room?
Yes. A company should be capable of presenting the key information required for investor review.
This typically includes:
incorporation and governance documents
cap table records
financial information
product materials
commercial evidence
legal and IP documentation where applicable
Structured capital requires structured diligence.
Does a company need a valuation?
A company must at least be capable of supporting a defensible valuation logic.
Even where the note structure does not operate exactly like a traditional priced round, there still needs to be enough commercial and financial substance to support how the capital is being structured and how future conversion or participation would be assessed.
Is a STACK Note for pre-seed startups?
Generally, no.
Pre-seed companies are usually too early, too unformed, or too speculative for a Structured Venture Note. STACK Notes are intended for Seed+ companies that have already crossed the threshold from idea to operating venture.
Can a company with only an idea qualify?
No. An idea alone is not enough.
A STACK Note requires enough underlying business substance to support diligence, capital deployment, and structured investor participation.
What is the purpose of a STACK Note?
The purpose of a STACK Note is to provide structured venture capital to companies that are no longer at the earliest stage, but are not yet best served by a full traditional institutional round.
It creates a more defined framework around capital entry and investor alignment at the point where a business begins to require greater precision.
Why would a company use a Structured Venture Note?
A company may use a Structured Venture Note because it offers a more deliberate capital structure at Seed+ stage, where founders and investors both need more clarity than very early-stage flexible instruments usually provide.
It is particularly relevant where the company has enough maturity to justify structure, but still wants a financing pathway aligned to its current stage of growth.
Is a STACK Note a legal category on its own?
No. STACK Note is a proprietary name. The underlying concept is a Structured Venture Note.
Does a STACK Note apply only to certain sectors?
No. The structure can apply across sectors, provided the company meets the Seed+ threshold and can satisfy the commercial, structural, and diligence requirements needed for this type of capital instrument.
What matters most when assessing eligibility?
The most important factors are:
stage maturity
real operating progress
evidence of traction
clean structure
diligence readiness
a credible use of capital
A STACK Note is intended for businesses that are already underway and now require structured growth capital.
