Why teams choose Assembled AI over Sierra
Purpose-built for omnichannel support: Assembled is the expert in support operations with our background in workforce management, building omnichannel solutions for brands like Stripe, Robinhood, and Hubspot. Forethought wasn't built for teams that run support on all async and live channels.
Transparency and control: Configure your workflows, preview AI behavior, customize your brand voice, and connect to your internal knowledge to ensure AI steps in exactly how and when you want it to. Sierra is limited in self-serve customization capabilities and requires additional headcount to maintain.
Support-first innovation: We don’t treat AI as a one-size-fits-all solution. Over the past several years, we’ve partnered with hundreds of customers to deeply understand support challenges. This insight drives tools that fit your workflows, enhancing support without adding unnecessary complexity.
