What do you think works more LTD or subscription model?

Great question, and one that depends a lot on your product and audience! For pdftopdf.ai, we’ve leaned towards the subscription model because it aligns well with ongoing usage and allows us to improve the product continuously. Subscriptions create a steady revenue stream, which helps invest in updates, support, and scalability. They also encourage us to maintain a strong relationship with users over time. That said, lifetime deals (LTDs) can be powerful in specific scenarios, like early-stage launches or targeting a niche audience that loves one-time costs. LTDs are great for building initial buzz, gaining feedback, and expanding your user base quickly. But they come with challenges—mainly the pressure to sustain your product long-term without recurring income from those early adopters. I’d say subscriptions are better for long-term growth and sustainability, while LTDs work well for short-term cash flow and brand awareness. Which one works for you might depend on your goals—are you building momentum or looking for a consistent, predictable revenue stream?

Ultimately, the best model depends on your specific product and target users. Subscriptions provide steady revenue for ongoing development and user support. They incentivize continuously delivering value to retain subscribers. LTDs can jumpstart growth by attracting a flood of initial users and cash flow. But the tradeoff is less predictable long-term revenue. For a mature product with clear demand, subscriptions may be ideal. For gauging interest in a new product, an LTD could be the way to go. Either way, the key is matching the model to your product roadmap and target audience's needs.
