AI SaaS challenges we solve
Common ai saas issues in apps built with Devin or Lovable.
Cost management and unit economics
Every user action costs you real money in API calls. If a user generates 100 requests a day and each costs $0.05, that's $5/day per user — $150/month. Without token tracking, usage tiers, and cost optimization, your AI SaaS can lose money on every customer.
Upstream API reliability
OpenAI and Anthropic APIs have outages, rate limits, and variable latency. Your SaaS needs fallback providers, retry logic with exponential backoff, request queuing, and graceful degradation. AI tools build direct API calls with no resilience — one upstream outage takes your entire product down.
Prompt management and versioning
Your prompts are your product's core IP. AI tools hardcode prompts in the source code. You need a prompt management system with versioning, A/B testing capability, and the ability to update prompts without deploying code. A bad prompt update shouldn't require a rollback of your entire application.
Output quality and consistency
AI responses vary in quality, format, and accuracy. Your paying customers expect consistent output. You need output validation, structured output parsing, retry logic for poor responses, and quality monitoring. One hallucinated response in a customer-facing context can destroy trust.
Usage-based billing
AI SaaS products typically need usage-based or credit-based pricing rather than flat monthly fees. Tracking usage accurately, enforcing limits in real-time, and integrating metered billing with Stripe requires careful implementation that AI tools don't provide.
Data privacy with AI providers
Your customers' data is being sent to third-party AI APIs. You need clear data processing agreements, the option to use providers that don't train on your data, and compliance with privacy regulations. Enterprise customers will specifically ask how their data is handled.
