Managing Multiple Client Demos Under NDA: The Agency Guide

The Nightmare Scenario:

Monday: You create a fashion e-commerce demo for Client A (luxury boutique).

Wednesday: Client B inquires (also luxury fashion boutique).

Thursday: You realize both clients are competitors in the same market.

Friday: You signed NDAs with both.

The Problem: How do you demo Client B without showing them Client A's data?

The Consequence: Violate NDA = lawsuit + reputation destroyed.

The Solution: Isolated demos.


The Agency Confidentiality Problem

Why This Is Common

Agencies attract similar clients:

  • You're good at fashion e-commerce → fashion clients find you
  • You specialize in restaurants → restaurant clients come
  • You nail SaaS dashboards → SaaS companies inquire

Result: Competing clients, same vertical, active at the same time.

The Traditional Nightmare

Old Approach:

Client A Demo (Week 1):

  • Build custom demo
  • Use Client A's brand, products, data
  • Store in shared codebase
  • Deploy to clienta-demo.vercel.app

Client B Demo (Week 3):

  • Need to build from scratch (can't reuse!)
  • Risk: Accidentally include Client A data
  • Time: Another 2 weeks
  • Cost: Another $12,000

Problems:

  1. Can't reuse work (confidentiality)
  2. Risk of data leakage
  3. Double the time and cost
  4. Scaling is impossible

Real Agency Disaster Stories

Case 1: The Leaked Competitor Data

Agency: 12-person design studio Niche: Restaurant booking systems

What Happened:

Month 1: Built demo for upscale Italian restaurant chain (8 locations, Rome-themed)

Month 2: Built demo for upscale German restaurant chain (12 locations, Bavaria-themed)

The Mistake:

  • Reused template from Client A
  • Forgot to regenerate data
  • Client B's demo included: "Ristorante Romano" (Client A's flagship)

Client B's Reaction:

"Why does our demo show our competitor's restaurant?"

Result:

  • NDA violation claim
  • $75K settlement
  • Lost both clients
  • Reputation damaged
  • 3 other clients left

Total Cost: $400K+ in lost revenue


Case 2: The Accidental Data Merge

Agency: 8-person agency Niche: E-commerce

What Happened:

Client A: Organic food marketplace Client B: Organic cosmetics marketplace Both: Berlin-based, overlapping customer base

The Mistake:

  • Used shared database for demos
  • Forgot to separate environments
  • Client B demo loaded Client A products
  • "Organic Apples €4.99" in a cosmetics shop

Client A's Reaction:

"Did you show our pricing to Client B?"

Result:

  • Lost Client A immediately
  • Legal threat
  • Had to prove no data breach
  • Lawyer fees: $15K
  • Reputation hit in Berlin market

Total Cost: $150K+ in lost projects


Case 3: The URL Mistake

Agency: 5-person boutique agency Niche: SaaS

What Happened:

Client A: CRM for real estate Client B: CRM for insurance Both: Targeting enterprise in Germany

The Mistake:

  • Named URLs obviously: clienta-crm-demo.vercel.app and clientb-crm-demo.vercel.app
  • Client B Googled their demo URL
  • Found Client A demo in same pattern
  • Realized they're seeing reused work

Client B's Reaction:

"You're building the exact same thing for our competitor?"

Result:

  • Client B felt unvalued
  • Refused to sign contract
  • Left bad review mentioning "template agency"
  • Lost $80K deal

Lesson: Even URLs leak information


The Branch Isolation Solution

What Is Branch Isolation?

Traditional Software Branches:

main (production code)
├── feature/new-checkout
├── bugfix/cart-issue
└── develop

Symulate Demo Branches:

fashion-ecommerce (project)
├── client-luxury-munich (Client A - private)
├── client-boutique-berlin (Client B - private)
├── client-fashion-vienna (Client C - private)
└── internal-testing (your team)

Key Difference:

  • Each branch = completely isolated data
  • Client A never sees Client B data
  • Zero risk of leakage
  • Reuse code, not data

How It Works

Step 1: Create Project Template

// api/products.ts - SHARED CODE
import { defineCollection, m, type Infer } from '@symulate/sdk'

const ProductSchema = m.object({
  id: m.uuid(),
  name: m.string(),
  price: m.number(),
  category: m.string(),
  image: m.internet.url()
})

export type Product = Infer<typeof ProductSchema>

// Define the collection structure - data will be customized per branch
export const products = defineCollection<Product>({
  name: 'products',
  basePath: '/api/products',
  schema: ProductSchema,
  // Note: seedCount and seedInstruction will be set per branch
  seedCount: 50,
  seedInstruction: '' // Override this in each branch
})

This is your reusable template.


Step 2: Create Client-Specific Branches

For Client A (Luxury Fashion Munich):

// Branch: client-luxury-munich
// Configure Symulate for this client's data
import { configureSymulate } from '@symulate/sdk'

configureSymulate({
  collections: {
    branch: 'client-luxury-munich', // Isolates this client's data
    persistence: 'memory' // or 'local' or 'cloud'
  }
})

// Override the collection seed instruction for this client
export const products = defineCollection<Product>({
  name: 'products',
  basePath: '/api/products',
  schema: ProductSchema,
  seedCount: 50,
  seedInstruction: `Luxury fashion boutique in Munich.
    Products: Designer dresses, handbags, shoes.
    Brands: Chanel, Gucci, Prada, Valentino.
    Pricing: €150-€2500.
    German names and descriptions.
    Target: wealthy customers aged 30-55.`
})

Deploy: luxury-demo-x7k2p.vercel.app (random URL)


For Client B (Fashion Boutique Berlin):

// Branch: client-boutique-berlin
// Configure Symulate for this client's data
import { configureSymulate } from '@symulate/sdk'

configureSymulate({
  collections: {
    branch: 'client-boutique-berlin', // Different branch = completely isolated data
    persistence: 'memory'
  }
})

// Override the collection seed instruction for this client
export const products = defineCollection<Product>({
  name: 'products',
  basePath: '/api/products',
  schema: ProductSchema,
  seedCount: 50,
  seedInstruction: `Contemporary fashion boutique in Berlin.
    Products: Streetwear, sustainable fashion, accessories.
    Brands: Local Berlin designers, eco-friendly brands.
    Pricing: €30-€400.
    German names, younger demographic.
    Target: urban millennials aged 25-40.`
})

Deploy: boutique-demo-m9f3j.vercel.app (different random URL)


Result:

  • Same codebase
  • Completely different data
  • No way for Client A to see Client B data
  • No way for Client B to see Client A data
  • Perfect confidentiality

Branch Strategy for Agencies

Naming Convention

BAD (Reveals too much):

❌ bmw-dealership-demo
❌ mercedes-competitor-2025
❌ audi-vs-bmw

GOOD (Maintains confidentiality):

✓ automotive-luxury-2025-01
✓ automotive-luxury-2025-02
✓ automotive-luxury-2025-03

Even better (Completely opaque):

✓ demo-a7f2k (random ID)
✓ demo-m3p9x (random ID)
✓ demo-j8r4n (random ID)

Why?

  • No one can tell who you're working with
  • URLs don't leak competitor information
  • Professional confidentiality maintained

Branch Lifecycle

// Create branch for pitch
Branch: client-proposal-2025-01
Status: Active
Purpose: Pitch demo
Created: 2025-01-10
Expires: 2025-01-31 (21 days)

// If they sign:
Branch: client-proposal-2025-01 → client-fashion-active
Status: Active
Purpose: Project development
Updated: 2025-01-15

// If they don't sign:
Branch: client-proposal-2025-01
Status: Archived
Auto-delete: 2025-02-15 (30 days after expire)

Benefits:

  • Clean up old demos
  • Don't pay for unused data
  • Automatic confidentiality (data deleted)

The Competing Clients Workflow

Scenario: Same Week, Same Industry

Monday: Fashion Client A inquires Wednesday: Fashion Client B inquires Both: Need demos by Friday

Old Approach (RISKY):

Monday-Thursday: Build Client A demo
Friday: Present Client A, they love it
Monday-Thursday: Scramble to rebuild for Client B
    ↓
Risk: Accidentally reuse Client A data
Cost: 2 weeks of work
Result: Stressed team

New Approach (SAFE):

Monday Morning (1 hour):

1. Create fashion-ecommerce project
2. Build product schema
3. Build UI components

Monday Afternoon (2 hours):

Branch: client-fashion-01
- Add Client A specific data instructions
- Deploy to demo-a7f2k.vercel.app
- Send to Client A

Tuesday Morning (30 minutes):

Branch: client-fashion-02
- Add Client B specific data instructions
- Deploy to demo-m3p9x.vercel.app
- Send to Client B

Result:

  • Both demos ready in 1.5 days
  • Zero risk of data leakage
  • Complete confidentiality
  • Reused code, not data

Security Best Practices

1. Access Control

// Team permissions
Project: fashion-ecommerce
├── You (Owner) - Full access
├── Developer A - Access to client-fashion-01
├── Developer B - Access to client-fashion-02
└── Designer - View only, all branches

Why?

  • Developer A can't accidentally see Client B data
  • Developer B can't accidentally see Client A data
  • Limited blast radius if mistake happens

2. Deploy URLs

BAD:

❌ client-name.youragency.com
❌ clientname-demo.vercel.app
❌ demo-clientindustry.netlify.app

Reveals:

  • Who you're working with
  • What industry
  • Your client relationships

GOOD:

✓ x7k2p.demo.youragency.com
✓ demo-x7k2p.vercel.app
✓ Random subdomain, no correlation

Reveals:

  • Nothing
  • Perfect for NDA compliance

BAD:

Email to Client:
"Here's the demo: demo-your-company-name.vercel.app"

Forward button: Dangerous
URL in subject line: Searchable

GOOD:

Email to Client:
"Here's your private demo preview:
[Password-protected link]

Password: [sent separately]

This demo expires in 14 days."

Benefits:
- Password protection
- Time-limited access
- Professional presentation

4. Data Cleanup

BAD:

Keep all demos forever
"We might need it later"
300 old demos sitting around

GOOD:

Demo lifecycle:
- Create for pitch
- Active during pitch (14 days)
- Archive if not won (30 days)
- Auto-delete after 60 days

Benefits:
- Clean workspace
- Lower costs
- Automatic confidentiality
- GDPR compliance

Handling Client Questions About Reuse

The Awkward Question

Client: "Is this a template you use for everyone?"

BAD Answer:

"Yes, we build the same thing for multiple clients."

Result: Client feels like they're getting commodity work

GOOD Answer:

"We have a proven architectural foundation that ensures quality and speed. However, your data, branding, and specific requirements are completely unique to you. The code is ours, but the experience is yours alone."

Result: Client understands value of speed + customization


The Competitor Question

Client: "Are you building this for our competitors too?"

BAD Answer:

"Well, we built a similar demo for Competitor Name last month..."

Result: NDA violation + lost trust

GOOD Answer:

"We maintain strict confidentiality for all clients. Each demo is isolated and client-specific. We can't and won't discuss other client work."

Result: Client trusts your professionalism


The Data Question

Client: "Where does this demo data come from?"

BAD Answer:

"Oh, we just reused data from our last fashion client."

Result: NDA concerns + lack of confidence

GOOD Answer:

"This data is AI-generated specifically for your demo based on your industry, target market, and requirements. It's completely unique to your project."

Result: Client impressed by customization
