MILLI — “Your daily money, backed by Bitcoin.”

1) One-line

A membership-based money app for millennials that pays you in sats for living your life, gives you low-friction credit when you need it, and proves its solvency every day with transparent, on-chain reserves.

2) Core promise (why millennials care)

  • Ownership > outsourcing. You keep keys (collaborative custody by default), we keep the rails smooth.
  • Cashflow first. We underwrite your life (income + bill history), not just your FICO.
  • Sats in, fees out. Everyday spending turns into Bitcoin automatically—no trading screens, no drama.

3) Flagship products

  1. SatsBack™ Card (debit & “charge” credit)
    • 1%–5% merchant-funded rewards paid in BTC (instant via Lightning).
    • Millennial-friendly perks: rent, childcare, groceries, transit.
    • Charge flavor (pay-in-full monthly) builds a clean cashflow history for future credit lines.
  3. FlexLine™ (BTC-secured line of credit)
    • Post BTC as collateral, borrow USD when needed.
    • Conservative LTV (e.g., 35–45%), auto-top-up from your vault to avoid liquidations.
    • Interest can be paid in USD or sats; no prepayment penalties.
  5. BillFlow™ (split big bills, zero headache)
    • We front eligible recurring bills (rent, daycare, medical, car insurance) and you smooth them over 3 months.
    • Underwritten by linked bank cashflows (Plaid), not just FICO. Late-fee-free by design.
  7. Round-to-Sats + Auto-DCA
    • Round every purchase to the next dollar; stack sats daily.
    • $0 fee on auto-DCA for Plus and Pro members; Lightning withdrawals included.
  9. Family Vaults (2-of-3 collaborative custody)
    • Millennial households = couples + kids. Shared vault with allowance streams paid in sats.
    • Emergency-recovery kit and human-readable key backups.
  11. Credit Builder (rent & bill reporting)
    • We report eligible payments to bureaus; unlock better APRs without carrying balances.

4) Business model (durable, diversified)

  • Interchange (Durbin-exempt partner): ~1.2–1.6% of card volume.
  • Net interest income from FlexLine + BillFlow (conservative APRs, transparent).
  • Membership: Free / Plus $9 / Pro $19 per month.
  • BTC purchase spread (0–0.8%, waived on tiers).
  • Merchant bounties for SatsBack offers.
  • B2B white-label: embed SatsBack & proof-of-reserves for brands.

Back-of-napkin (illustrative):

50k active members × $600 monthly card spend = $30M volume → at 1.4% interchange ≈ $420k/mo.

$50M average lending book × 5% net yield ≈ $2.5M/yr ($208k/mo).

25k paid members (avg $12/mo blended) ≈ $300k/mo.

→ Early run-rate: **$928k/mo** before opex. (Keep ops lean, partner smart.)

5) Treasury & risk (Bitcoin-backed, boring-safe)

  • Proof-of-Reserves & Proof-of-Liabilities: daily Merkle attestations + independent auditor reports.
  • Liquidity ladder: 30/60/90-day cash runway segregated from BTC treasury.
  • Hedging policy: We don’t speculate with collateral. Match currency of liabilities; BTC treasury is long-only, cold-stored, majority multisig.
  • Stress-tests: LTV triggers assume –50% BTC drawdown in 24h; auto-margin buffers protect members.

6) Compliance path (US-first, global-ready)

  • Register as MSB (FinCEN); obtain state MTLs; partner with FDIC-insured sponsor bank for cash + cards.
  • Lending licenses (or rent-a-charter partner) for FlexLine/BillFlow; UCC Article 9 filing on BTC collateral.
  • KYC/AML, OFAC, 314(b), adverse media, and SAR program.
  • Entity: Delaware Public Benefit Corp (PBC) — mission locked: financial sovereignty via Bitcoin.

7) Product tiers

  • Free: SatsBack up to 1%, round-ups, basic vault, Lightning withdrawals (fair-use).
  • Plus ($9): 2% base SatsBack, $0 fee DCA/withdrawals, BillFlow access, higher limits, rent reporting.
  • Pro ($19): Up to 5% SatsBack offers, FlexLine access & best APR band, family vaults, travel protections, priority support.

8) Tech stack (ship fast, ship safe)

  • Wallet & custody: Mobile app (iOS/Android) with collaborative custody (2-of-3); Taproot-first; descriptor-based wallets; PSBT flows.
  • Lightning: LDK-based node or LSP partner; MPP + AMP support; splicing for UX.
  • Core infra: Kotlin/Swift, gRPC micro-services, Postgres + Ledger DB, Kafka for events, Terraform on AWS.
  • Risk/underwriting: Cashflow models from linked accounts (Plaid), employment signals, alternative data (with member consent).
  • Observability: Realtime solvency dashboard; open API for third-party verifiers.

9) Brand, voice, vibe

  • Name: MILLI (millennial + millisats).
  • Tagline: “Stack every swipe.”
  • Palette: high-visibility orange with clean monochrome.
  • Tone: optimistic, sovereign, no-nonsense. Zero casino vibes.

10) Go-to-market (land & expand)

  • Beachheads: LA (Culver City!), Austin, Miami—dense millennial pros + creator economies.
  • Ambassadors: fitness, photography, indie-hacker, and creator niches (your wheelhouse).
  • Sats Challenges: 30-day “Debt-free in Sats” sprint; “Rent-to-Sats” campaigns with landlord partners.
  • Employer perks: Offer MILLI as a post-tax benefit; auto-DCA from payroll with matching in sats (employer marketing angle).

11) 90-day action plan

Days 0–15

  • Incorporate MILLI PBC; lock mission.
  • RFP to sponsor bank, BIN sponsor, LSP, and custody collaborators.
  • Draft compliance program; hire fractional BSA officer & GC (outside counsel).

Days 16–45

  • Build alpha: wallet + SatsBack engine + round-ups + basic Lightning.
  • Close partner term sheets; start state MTL filings (prioritize CA, TX, FL).
  • Finalize card art + brand guidelines.

Days 46–90

  • Private beta (1k members): SatsBack, round-ups, Lightning withdrawals.
  • Pilot BillFlow with 3 landlord/property-manager partners.
  • Treasury dashboard live + first PoR/PoL attestations.
  • Waitlist push + creator partnerships; announce PBC status.

12) North-star metrics

  • Daily Active Stackers (DAS), SatsBack redemption rate, 30-day retention, Carded spend/member, BTC AUM, Funding cost vs net yield, Proof-of-Reserves checkouts (yes, make it a vanity metric—transparency is a feature).

13) Competitive moat

  • Radical transparency (live solvency) + collaborative custody (keys with you).
  • Cashflow underwriting for real-life bills (rent/childcare) vs generic revolving credit.
  • Millennial household suite (family vaults, bill smoothing, rent reporting) > generic “crypto card.”

14) Sample landing copy

Own your money.

Meet MILLI—the money app that turns every swipe into sats, smooths your biggest bills, and proves its reserves daily. No casino. No gimmicks. Just sovereignty with training wheels.

15) Name & tagline alternates (just in case)

  • ORANGE HOUSE — “Make home payments, stack sats.”
  • CITIZEN SATS — “Spend fiat. Keep Bitcoin.”
  • STACKJOY — “Joyful money, backed by Bitcoin.”

If you want, I’ll turn this into a tight 10-slide investor deck and a one-page spec for the SatsBack engine and FlexLine underwriting so you can start calls today. Ready to go god-mode? 🚀🥇🧡
