Word of mouth

Customers discovered the product for 2FA sharing and expanded to customer support use cases organically

Growth Levers

  • Add WhatsApp integration as recommended by multiple commenters to expand beyond SMS
  • Target customer support teams who want to offer SMS as a support channel through Slack
  • Market the 2FA code sharing use case specifically to teams with shared accounts
  • Address A2P 10DLC compliance concerns proactively in marketing to build trust with US-based businesses
  • Expand to international markets where SMS remains dominant before WhatsApp fully displaces it

First Customer Strategy

The product was built to solve the founder's own pain point: receiving 2FA codes sent to a colleague's phone for shared work accounts. After solving this personal need, the tool expanded as customers adopted it for SMS-based customer support, where end users prefer texting over email or chatbots.

Pricing Insight

No specific pricing mentioned in the thread. The product uses Stripe for payments and relies on carrier integrations, suggesting a per-message or subscription pricing model to cover carrier costs.

New Market Opportunities

  • WhatsApp Business integration Two commenters independently suggested WhatsApp support — one directly recommended it, another noted WhatsApp for Business has eaten the SMS space in Brazil
  • International messaging markets Commenter from Brazil highlighted that SMS is dying there in favor of WhatsApp, suggesting the product needs to expand messaging channels to compete globally
  • A2P 10DLC compliant messaging Commenter asked about A2P 10DLC compliance, indicating this is a real concern for businesses wanting to use SMS-to-Slack and an area of competitive differentiation

Key Takeaways

  • • Products born from personal frustration (shared 2FA codes) often discover larger use cases (customer support) after launch
  • • SMS remains a preferred channel for many end users, but WhatsApp is eating SMS in international markets — multi-channel is key
  • • Building on top of established platforms like Slack provides a built-in distribution channel and reduces user adoption friction
  • • Regulatory compliance (A2P 10DLC) is both a barrier to entry and a moat for products that handle it well
  • • End users preferring SMS over email and chatbots is a powerful positioning insight for customer support use cases
