SaaS valuations are under pressure. Growth has slowed from 30%+ to the low teens, while multiples remain high compared to faster-growing sectors like semiconductors. SaaS firms must leverage AI to reignite top-line growth or their valuations will inevitably compress to match their new reality.

Unlike traditional SaaS, achieving product-market fit in AI is not enough for survival. The high and variable costs of model inference mean that as usage grows, companies can scale directly into unprofitability. This makes developing cost-efficient infrastructure a critical moat and survival strategy, not just an optimization.

With AI accelerating development, the key challenge is no longer building faster; it's getting completed features through legal, marketing, and other operational hurdles. Organizations must now re-engineer these internal processes to match the new pace of creation.

During a 5x growth period, Fixer's support response times went from 5 minutes to 5 hours, jeopardizing customer trust. The team had only planned for their growth strategies failing, not succeeding. This highlights the critical need to build infrastructure for best-case scenarios, not just worst-case ones.

Many high-growth AI B2B companies face a hidden bottleneck: a shortage of Forward Deployed Engineers (FDEs) who can get customers implemented and running. Despite huge demand, growth is limited by the number of these skilled professionals. This forces them to operate like services businesses, where hiring and training FDEs is the primary constraint.

For founders, AI tools are excellent for quickly building an MVP to validate an idea and acquire the first few customers—the hardest step. However, these tools are not yet equipped for the large-scale, big-picture thinking and edge-case handling required to scale a product from 100 to a million users. That stage still requires human expertise.

Founders shouldn't expect AI to automate a business function instantly. Real-world adoption is a gradual "glide path" where automation scope increases over time. This requires building systems that facilitate human-AI interaction, allowing humans to coach the AI and vice versa for a smooth transition.

The proliferation of AI has dramatically reduced development time, shifting the primary constraint in product delivery from engineering capacity to the customer's ability to learn and integrate new features into their workflow. More output no longer guarantees more value.

SaaS growth relies on upselling features and adding seats. AI challenges this by enabling customers to build their own integrations that were once expensive upsells. Furthermore, if AI keeps team sizes static, the "expand" motion of selling more seats vanishes.
