From Pricing Page to Stripe: The Engineering Decisions That Determine Whether Your Net Revenue Retention Cracks 110%
Most SaaS teams wire up Stripe in a weekend and call it done. The teams hitting 110%+ NRR make a different set of engineering decisions — on proration, upgrade flows, dunning, and metered billing — that compound quietly into millions of ARR.
LLM Agents on the Symfony Workflow Component: State Machines, Idempotent Steps, and Replayable Failures
Most production LLM agents fail not because the model is wrong, but because the orchestration layer cannot recover when one step times out. This post shows how the Symfony Workflow Component — built for business processes — makes an excellent agent loop runtime with explicit state, replayable transitions, and built-in audit traces.
