Growth Channels

1. WhatsApp Viral Loops

Every transaction creates sharing:

Buyer purchases → Gets receipt with "via Yebo"
Seller receives payment → Notification with link
Both get: "Share to earn 50 KES"

javascript

async function triggerViralLoop(transaction) {
  // Buyer share
  await sendMessage(transaction.buyerId, {
    text: `✅ Purchase complete! Share Yebo with friends, earn KES 50 each.`,
    buttons: [
      { label: 'Share on WhatsApp', action: 'share', url: referralUrl }
    ]
  });
  
  // Seller share
  await sendMessage(transaction.sellerId, {
    text: `💰 KES ${amount} received! Know someone who sells? They get KES 100 free credits.`,
    buttons: [
      { label: 'Invite Sellers', action: 'share', url: sellerReferralUrl }
    ]
  });
}

2. Eneza Distribution

Leverage 12,000+ Eneza users:

Already posting WhatsApp Status ads
Already have audience
Natural upgrade to full Yebo

Eneza user posts ad
    ↓
"Want to accept payments too? Connect YeboShops"
    ↓
One-click upgrade
    ↓
Full Yebo user

3. B2B Partnerships

Partner Type	Value
Employers	Bring job seekers
Schools	Bring learners
Trade associations	Bring sellers
Mobile money agents	Distribution

4. Content Marketing

Success stories (sellers making money)
"How to" content (use agent for X)
SEO for job/commerce searches

Referral Program

javascript

const referralProgram = {
  referrer: {
    perSignup: 50,  // KES
    perTransaction: 10,  // KES (first 5)
    max: 1000  // KES total per referrer
  },
  referee: {
    signupBonus: 100,  // KES credits
    firstTransactionBonus: 50  // KES
  },
  tracking: {
    code: 'unique_per_user',
    attribution: '30_days',
    fraud: ['same_device', 'same_ip', 'velocity']
  }
};

Naira payments needed

Payment Integration:

javascript

// Add OPay support
const opayProvider = {
  name: 'opay',
  country: 'NG',
  currency: 'NGN',
  
  deposit: async (amount, phone) => {
    // OPay API call
  },
  
  withdraw: async (amount, phone) => {
    // OPay API call
  },
  
  webhook: '/webhooks/opay'
};

Timeline:

Month 1: OPay integration
Month 2: Palmpay integration
Month 3: Local testing
Month 4: Soft launch
Month 5: Full launch

4.3 Technical Scaling

Current Architecture (10K users)

Single region (Kenya)
├── Cloud Run (auto-scaling)
├── Neon PostgreSQL
├── Single WhatsApp number
└── Cloudflare CDN

Target Architecture (1M users)

Multi-region
├── Load Balancer (global)
├── Cloud Run (per region)
│   ├── europe-west1 (EU/Africa)
│   ├── us-central1 (Americas)
│   └── asia-east1 (Asia)
├── PostgreSQL (read replicas)
│   ├── Primary (write)
│   └── Replicas (read, per region)
├── Redis (caching, sessions)
├── Multiple WhatsApp numbers
└── Cloudflare (CDN + Workers)

Database Scaling

Read Replicas

javascript

// Read from replica, write to primary
const db = {
  primary: new PrismaClient({ url: PRIMARY_URL }),
  replica: new PrismaClient({ url: REPLICA_URL }),
  
  read: async (query) => db.replica.$queryRaw(query),
  write: async (query) => db.primary.$queryRaw(query)
};

Sharding (if needed)

javascript

// Shard by user_id
function getShard(userId) {
  const hash = hashCode(userId);
  return hash % NUM_SHARDS;
}

const shards = [
  new PrismaClient({ url: SHARD_0_URL }),
  new PrismaClient({ url: SHARD_1_URL }),
  // ...
];

async function query(userId, query) {
  const shard = shards[getShard(userId)];
  return shard.$queryRaw(query);
}

Caching Strategy

javascript

// Cache user profiles (high read)
async function getUser(userId) {
  const cached = await redis.get(`user:${userId}`);
  if (cached) return JSON.parse(cached);
  
  const user = await db.users.findUnique({ where: { id: userId } });
  await redis.setex(`user:${userId}`, 3600, JSON.stringify(user));
  return user;
}

// Cache product listings (high read)
async function getListing(listingId) {
  const cached = await redis.get(`listing:${listingId}`);
  if (cached) return JSON.parse(cached);
  
  const listing = await db.listings.findUnique({ where: { id: listingId } });
  await redis.setex(`listing:${listingId}`, 300, JSON.stringify(listing));
  return listing;
}

Queue System

javascript

// Async job processing
const queues = {
  notifications: new Queue('notifications'),
  emails: new Queue('emails'),
  aiProcessing: new Queue('ai'),
  webhooks: new Queue('webhooks')
};

// Process in background
queues.aiProcessing.process(async (job) => {
  const { photos, userId } = job.data;
  const listing = await generateListing(photos);
  await createListing(userId, listing);
  await notify(userId, 'Listing created!');
});

4.4 Platform Ecosystem

Third-Party Integration

Open APIs for partners to build on Yebo:

YeboID as Auth Provider

javascript

// Any app can use YeboID for login
app.get('/login/yebo', (req, res) => {
  res.redirect(`https://id.yebo.com/oauth/authorize?
    client_id=${CLIENT_ID}&
    redirect_uri=${CALLBACK_URL}&
    scope=profile,email`);
});

app.get('/callback', async (req, res) => {
  const { code } = req.query;
  const tokens = await yeboid.exchangeCode(code);
  const user = await yeboid.getUser(tokens.access_token);
  // User is authenticated
});

YeboSafe as Payment Provider

javascript

// Any app can use YeboSafe for payments
const payment = await yebosafe.createPayment({
  amount: 1000,
  currency: 'KES',
  description: 'Order #123',
  callbackUrl: 'https://myapp.com/payment-complete'
});

// Redirect user to payment page
res.redirect(payment.checkoutUrl);
