A diligence guide, with an explicit scope.
A starting point for investor diligence: what could create a claim, how it could affect invested capital, and what evidence to request.
General information and issue spotting, not legal, tax, or investment advice, an investment recommendation, or a legal opinion about 21f. This is not an exhaustive risk disclosure or offering document. Actual exposure depends on the facts, jurisdiction, investor role, and signed agreements; review those with qualified advisers before committing capital.
01 / THE INVESTOR’S POSITION
Your role shapes your exposure.
Business liabilities can reduce the value of your investment. Whether you also face personal liability requires a separate review of the entity, documents, and your involvement.
01
Capital invested
Operating losses and company claims can reduce the value of an ownership interest to zero. A limited-liability structure, if applicable, addresses responsibility for debts; it does not protect the investment from losing value.
Questions to resolve
What security is being purchased, and what ranks ahead of it?
Can the interest be transferred, and is any exit or distribution required?
02
Additional commitments
A personal guarantee, an unpaid purchase commitment, or an enforceable obligation to contribute more capital can create a separate payment obligation. Read every signature block and incorporated agreement; an investment amount is not necessarily the limit of contractual exposure.
Questions to resolve
Is any guarantee or additional contribution required?
What events trigger payment, and is the obligation capped or terminable?
03
Conduct and decision-making
A board seat, management role, control position, or participation in fundraising introduces questions distinct from passive ownership. Duties, potential statutory liability, conflicts, defense-cost advancement, and coverage require analysis of the actual role.
Questions to resolve
What authority and duties accompany the role?
Who pays defense costs, and what happens if indemnification or insurance is unavailable?
THE CURRENT STARTING POINT
A concept to evaluate. Evidence to establish.
What this page is based on
21f currently presents a public product demo, an Arizona family workspace concept, a proposed subscription model, and an included wireless offer. The 700,000-account audience and $100 monthly price are planning assumptions; revenue scenarios are not verified operating results.
What remains unverified
Formation documents, governing law, capitalization, financing agreements, financial statements, insurance policies, carrier contracts, and regulatory determinations have not been supplied for this overview. No completed legal review or operational approval is represented.
02 / POTENTIAL BUSINESS LIABILITIES
Where exposure can develop.
Each area connects a possible trigger to its investment consequences and the evidence to request. These are diligence topics, not findings of a violation or numerical risk ratings.
01Financing & disclosureThe fundraising path must fit the public story.Public investor pages and financial illustrations need review alongside the eventual securities offering.
What could trigger exposure
If public materials solicit investment under an incompatible exemption, or audience, revenue, partnership, or approval statements omit material qualifications, offering and misstatement claims could follow. A disclaimer alone does not determine whether a communication is an offer.
What it could mean for investors
Potential consequences include a delayed raise, rescission demands, enforcement, defense costs, and reduced runway. Exempt offerings remain subject to antifraud rules.
Evidence to request
Request the selected federal and state offering pathway, eligibility checks, filing calendar, and counsel review of all public and private fundraising materials.
Reconcile every model with its assumptions. Verify paid traction, market evidence, and contracts separately from projections or founder estimates.
Confirm who can solicit investors and whether any placement or referral compensation requires a registered intermediary.
02Capital at riskRevenue potential does not establish an investment return.Loss of capital, dilution, and an uncertain exit are central investment risks even without a legal dispute.
What could trigger exposure
If adoption, retention, collections, or delivery costs miss the model, 21f may need more capital, reduce operations, or cease trading. Later financing may change ownership percentages and economic priority.
What it could mean for investors
An investor could lose the entire amount invested and may be unable to sell when desired. Debt, preferences, fees, and new issuance can reduce proceeds available to a particular investor.
Evidence to request
Request a fully diluted capitalization table, all outstanding securities and debt, and a proceeds waterfall for downside, new-financing, and exit scenarios.
Review cash, liabilities, burn, runway, use of funds, and bundle economics including wireless costs, support, credits, refunds, and acquisition.
Read transfer restrictions, conversion terms, liquidation preferences, participation rights, and any further funding obligations in the actual instrument.
03Investor role & liabilityOwnership, control, and personal commitments differ.Company liabilities can reduce investment value without automatically becoming an investor’s personal debts.
What could trigger exposure
Exposure needs separate analysis if an investor signs a guarantee, commits additional capital, becomes a director or manager, exercises control, or participates in misleading statements or other actionable conduct.
What it could mean for investors
Depending on governing law and the facts, claims or contractual payments may extend beyond the original investment. Entity protections cannot be assumed before the entity and investor role are established.
Evidence to request
Verify the legal entity, formation jurisdiction, good standing, governing documents, and the precise capacity in which each document is signed.
Identify guarantees, capital calls, indemnities, board duties, conflicts, and authority to speak or act for the business.
Review indemnification, advancement of defense costs, and directors and officers coverage, including exclusions and the company’s ability to pay.
04Children, families & dataSensitive family information raises the stakes.Learner profiles, household records, receipts, and future integrations require a documented privacy and security model.
What could trigger exposure
An unauthorized disclosure, excessive retention, vendor misuse, or a mismatch between actual data practices and privacy promises could create exposure. COPPA applicability depends on the service’s audience and collection practices, including child-directed services and knowing collection from children under 13.
What it could mean for investors
Incident response, notice obligations, remediation, enforcement, litigation, and lost customer trust could consume cash and delay growth. Parent-entered information alone does not settle every privacy obligation.
Evidence to request
Request a data map and counsel’s assessment of child access, age handling, parental consent, education-record rules where relevant, and applicable state privacy laws.
Review access-control evidence, vendor terms, retention and deletion rules, recovery exercises, and an incident response plan with jurisdiction-specific notice analysis.
Confirm production safeguards through evidence; a fictional demo and descriptions of security features are not a security audit.
05Arizona education & ESAFunding eligibility and incentives need separate answers.A parent administration subscription, bundled wireless, and proposed referral credits must each be evaluated on their actual terms.
What could trigger exposure
If families rely on incorrect filing guidance or treat an unapproved expense as reimbursable, disputes may arise. A.R.S. 15-2402(J) restricts providers from returning or sharing ESA monies with a parent or student; the proposed $25/$25 credits require specific review.
What it could mean for investors
Expense denials, refund disputes, incentive redesign, regulatory scrutiny, or changes in ESA policy could weaken demand and acquisition economics. Vendor enrollment would not establish approval of every purchase.
Evidence to request
Request a written eligibility analysis for the exact subscription and bundle, and any relevant agency determinations; do not infer that all customers can use ESA funds.
Resolve referral funding source, credits, refunds, and invoice allocation before launching an ESA-related incentive. No eligibility or rebate treatment is established here.
Review source ownership and update procedures for homeschool versus ESA guidance, county filings, and statements about what 21f actually submits or verifies.
06Wireless deliveryThe included line carries contractual and regulatory dependencies.The advertised 2GB data and unlimited talk/text benefit needs an executed delivery arrangement and complete plan terms.
What could trigger exposure
If the network partner fails, wholesale costs rise, or the advertised benefit exceeds contracted service, 21f could face customer claims or service disruption. Telecom obligations depend on the actual provider, reseller, and data-handling roles.
What it could mean for investors
Minimum commitments, fraud, replacement service, refunds, compliance costs, and carrier concentration could pressure margins and retention.
Evidence to request
Request the signed carrier or wholesale agreement, provider-of-record determination, pricing, minimums, termination rights, indemnities, and continuity plan.
Assign responsibility for customer network information, emergency calling, porting, accessibility, applicable disclosures, taxes, fees, and regulatory filings with telecom counsel.
Verify included lines, data renewal, coverage, devices, overages, support, and cancellation. Device safety tips do not establish network-level protection or guaranteed safety.
07Subscriptions & marketingEnrollment promises must hold through cancellation.Recurring billing, “free” benefits, referral endorsements, and refunds are part of the investment risk picture.
What could trigger exposure
If paid-subscription conditions or extra charges are unclear, customers are billed without informed consent, cancellation is obstructed, or rewarded endorsements omit material connections, complaints and claims could follow.
What it could mean for investors
Refunds, chargebacks, payment-processor restrictions, enforcement, and higher churn could impair collections and invalidate acquisition assumptions.
Evidence to request
Review the complete checkout, affirmative consent records, renewal notices where required, cancellation journey, refund terms, and the handling of wireless service at cancellation.
Confirm all conditions of the included benefit are prominent and consistent across ads, landing pages, billing, and support.
Review referral terms and endorsement disclosures; map state requirements to customer locations before expansion.
08Contracts, IP & governanceContract rights and coverage determine how a loss is absorbed.Vendor dependency, ownership of the product, management decisions, and insurance terms affect recoverability and enterprise value.
What could trigger exposure
A vendor outage or termination, disputed code or content ownership, a related-party conflict, or an uninsured claim could require replacement work or interrupt operations. Paying a contractor does not by itself establish every necessary IP right.
What it could mean for investors
A company may bear costs above a vendor’s liability cap or outside insurance coverage. Unresolved ownership and governance issues can also obstruct financing or an exit.
Evidence to request
Request signed IP assignments and licenses, contractor agreements, open-source and content inventories, and permission for proposed integrations and data use.
Review critical vendor liability caps, indemnities, service commitments, data export, termination assistance, and alternative suppliers.
Review governance approvals, conflicts and related-party dealings, pending or threatened claims, and actual D&O, cyber, and technology E&O policy terms with counsel and a broker.
Order is for reading, not a ranking of likelihood or severity. Actual exposure depends on the facts, contracts, jurisdictions, and the service as launched.
03 / BEFORE COMMITTING CAPITAL
Ask for evidence. Record the open questions.
A practical starting packet for an investor and their advisers. These are proposed review steps; completion has not been represented or verified.
REVIEW 01
Entity and financing documents
Formation and governing documents, capitalization table, prior securities, debt, proposed instrument, approvals, and offering review.
Decision it informs
Establish exactly what is being acquired, who owes what, and how a future financing or exit changes the outcome.
REVIEW 02
A reconciled downside model
Financial statements, cash and liabilities, collections, actual service quotes, cohort evidence if available, and a costed use of funds.
Decision it informs
Separate demonstrated performance from assumptions and determine the runway under slower growth or higher delivery costs.
REVIEW 03
Written launch determinations
ESA and incentive analysis, telecom responsibility allocation, subscription terms, privacy applicability review, and any required approvals.
Decision it informs
Identify dependencies that must be resolved before the corresponding offer, data collection, or paid service launches.
REVIEW 04
Evidence that safeguards work
Access and deletion checks, incident and recovery exercises, consent and cancellation records, and source-maintenance responsibilities.
Decision it informs
Evaluate implemented controls and their owners without treating a checklist or public demo as proof of readiness.
REVIEW 05
Contracts, ownership, and coverage
Carrier and vendor agreements, IP chain of title, indemnities, guarantees, insurance policies and exclusions, and claims history.
Decision it informs
Understand which losses remain with the company or investor and whether contractual recovery would be practical.
REVIEW 06
An agreed reporting process
Proposed reporting rights, budgets, milestone evidence, conflict procedures, and escalation for material incidents or legal changes.
Decision it informs
Set the information and decision rights in definitive agreements; the roadmap’s suggested cadence does not grant investor rights.
Safeguards reduce exposure; they do not erase it. Liability caps, indemnities, insurance, and investor rights depend on enforceability, exclusions, available funds, and the final agreements. A public overview cannot establish that a particular investment is suitable or protected.
