Um toque pra dizer 'foi pessoal ou empresa' — e sua margem MEI fica clara em tempo real

Problem

Sou MEI, recebo Pix de cliente e pago meu mercado no mesmo Nubank. Não sei quanto a empresa está dando de margem real, nem se já passei perto do teto de R$81K do MEI. Bling e Conta Azul são caros e complicados pra mim — eu não tenho contador, sou só eu.

Audience

Brazilian solo MEI / family micro-businesses (~14 million MEIs as of 2024) — home-based service providers (manicures, professores particulares, freelance designers), small e-commerce sellers, agricultural family businesses. Specifically: those with ONE bank account (typically Nubank or Inter PJ-light) mixing personal + business Pix on the same CPF, no contador, ~R$3-7K monthly revenue.

What we ship

**Core features (MVP)**

  • Open Finance Brasil OAuth (Nubank, Inter, Itaú, Bradesco, C6) — every 4 hours pull new Pix transactions
  • WhatsApp daily 20:00 push — "Hoje teve 7 transações novas, vou listar uma por uma": each one 1-tap pessoal/empresa
  • AI heuristic auto-suggestion: counterparty CNPJ → empresa (Receita Federal API lookup), recurring valor padrão → empresa, known friend → pessoal
  • Real-time MEI dashboard: total revenue YTD, % of R$81K cap, annual projection
  • **Critical alerts**: 70% cap reached → "Cuidado, você está a 6 meses do teto MEI" + 90% → "Migrar para ME?" recommendation
  • DAS reminder (5th of month), generates Pix QR for direct Sebrae payment
  • Year-end IRPF helper: generates personal IRPF spreadsheet + DEFIS empresa anual

**Primary user flow**

1. Landing "MEI sem contador? Tira o caos do Pix em 5 minutos" — CTA "Conectar grátis"

2. Pluggy OAuth — 3 minutes, full Pix history imported

3. WhatsApp connect — every day 20:00 "What was Pix R$340 from João Silva?" 1-tap

4. After 7 days — dashboard ready, real margin visible

5. Pricing trigger: after 14-day free trial — R$19.90/mo

**What it looks like**

  • **Landing page**: hero "MEI, separar Pix pessoal de empresa virou um toque" + WhatsApp screenshot with one question + Pix QR CTA
  • **Main app screen**: progress bar to R$81K cap, monthly revenue chart, margin % green/red
  • **Output / notification**: WhatsApp daily 20:00 message + monthly DAS reminder with Pix QR + year-end "Sua DEFIS está pronta"

**MVP build plan (11 days)**

  • Day 1-3: backend (User, MEI, Account, Transaction, Tag), JWT, Pluggy OAuth, Receita Federal CNPJ lookup
  • Day 4-7: WhatsApp Twilio cron daily transaction-tagging flow, AI auto-suggestion (CNPJ heuristic + Claude Sonnet pattern matching)
  • Day 8-9: dashboard (R$81K cap progress), DAS reminders, IRPF/DEFIS export
  • Day 10-11: PT-BR landing, deploy, soft launch r/empreendedorismo and r/MEI

Reasoning

14M MEIs in BR — massive audience. Existing ERPs (Bling, Conta Azul, Omie) target SMBs with a contador, not solo MEIs. MaisMei and Meu MEI Digital are fiscal-only (DAS reminders), not financial separators. Mobills/Organizze — generic, no PJ/PF split. This product combines (a) auto-Pix-categorization via Open Finance, (b) WhatsApp 1-tap UX (low friction), (c) MEI-cap monitoring (critical for compliance — Receita Federal actively cross-checks Pix vs CPF/CNPJ via Convênio ICMS 166). Buildable in 11 days — Pluggy SDK, public CNPJ API, standard Twilio WhatsApp. High loyalty (compliance is critical), low churn because monthly DAS payments = re-engagement.

Quick competitive read

  • **Conta Azul** [CMP-088-conta-azul] — R$65/mo SMB ERP, contador-driven; structurally excluded from solo-MEI by pricing model
  • **Bling** [CMP-088-bling] — R$25.90/mo MEI tier, but e-commerce / NF-e centric; misfit for service-MEI
  • **Tiny ERP** [CMP-088-tiny-erp] — R$39/mo Essencial floor; vacates the R$19.90-R$39 corridor we occupy
  • **Mobills** [CMP-088-mobills-mei] — R$16.90/mo PF tracker; closest pricing pressure but no PJ/PF split, no MEI compliance layer
  • **MaisMei** [CMP-088-maismei] — R$14.90/mo MEI fiscal app (DAS + manual NF-e), no Open Finance bank-sync; complementary not substitutable
  • **Market density**: medium (5 mapped competitors, all with structural gaps).
  • **White-space**: solo-MEI Pix-categoriser + cap-monitor combo via Open Finance + WhatsApp 1-tap UX — uncontested in BR. Competitive pressure 7/10. Direct pricing pressure: Mobills (R$16.90) and MaisMei (R$14.90) — defended by MEI-compliance layer + WhatsApp distribution moat.

Initial pricing hypothesis

R$19.90/mo (justified: user already pays R$22 for Conta Azul-equivalent, our pricing is 10% cheaper). 14-day free trial. ARPU R$240/year. Upsell to R$39/mo "MEI Pro" with auto NFS-e issuance via Sebrae integration.

Distribution hypothesis

Reddit r/empreendedorismo and r/MEI launch + SEO ("app MEI separar Pix", "controle financeiro MEI sem contador", "DAS automatico") + LinkedIn for entrepreneur families + Sebrae digital course partnerships + WhatsApp groups with MEI consultants — R$50 Pix referral program per activation.
