Guest: Mark Walker, CEO at Nue.io

SaaS pricing isn’t breaking because of AI — it’s breaking because most revenue systems were never built for the speed and complexity of today’s models.

In this episode, Mark Walker, CEO of [Nue.io](http://Nue.io), joins host Ken Lempit to unpack why modern SaaS and AI companies are abandoning legacy CPQ and billing stacks for a flexible, unified revenue infrastructure built for rapid change.

Key highlights:

- Why legacy CPQ + billing can’t support modern SaaS pricing
- How committed consumption + bank-billed models are reshaping monetization
- Why speed of configuration is now a GTM advantage
- What RevOps must rethink as pricing experiments explode
- How elite teams thrive on hard problems and high-velocity execution

If you’re a B2B SaaS founder, CRO, CMO, or RevOps leader navigating complex pricing models, upgrading your revenue stack, or preparing for next-gen AI monetization, this conversation will change how you think about scaling.
