Start-ups should focus on customer experience (CX) to engage customers and drive profits. CX is intrinsically linked to employee experience and companies that excel at CX have satisfied employees. There are five ways for start-ups to redefine their CX strategy: 1) Map the customer journey to identify touchpoints, 2) Improve onboarding to address conversion issues, 3) Provide real-time support, 4) Measure CX with metrics like CSAT and NPS, 5) Actively collect and act on feedback. Focusing on CX from the start is important for start-ups in today's connected world.
