Common Pitfalls

Mistake 1: Building Before Selling

Wrong: Spend 6 months building perfect product Right: Sell before you build, validate with real customers

Mistake 2: Targeting Everyone

Wrong: "We serve all industries" Right: Pick one industry, dominate it, then expand

Mistake 3: Underpricing

Wrong: $200/month to win customers Right: Charge premium ($1K+), provide premium value

Mistake 4: No Differentiation

Wrong: "We do voice AI" (generic) Right: "We help real estate agents capture 3x more leads"

Mistake 5: Trying to Build Platform

Wrong: Build proprietary AI from scratch Right: Use existing platforms, focus on service/implementation

Success Factors

1. Pick a Niche

Don't be everything to everyone. Pick one industry and become the expert.

2. Prove ROI Quickly

Show results within 30 days. Clear metrics customers care about.

3. Provide White-Glove Service

Early customers need hand-holding. Make them wildly successful.

4. Get Testimonials

Case studies and video testimonials are gold for sales.

5. Build Recurring Revenue

Prioritize MRR over one-time fees. Predictable revenue = scalable business.

6. Stay Close to Customers

Regular check-ins, proactive optimization, anticipate needs.
