Overview
Drift
Drift helps you transform your website from a static brochure into a 24/7 sales engine. Instead of forcing your potential customers to fill out long forms and wait days for a follow-up, you can engage them the moment they show interest. The platform uses AI-powered bots to qualify leads, answer common questions, and even book meetings directly on your sales team's calendars while you sleep.
You can create personalized experiences for your most important accounts by recognizing them the second they land on your site. By connecting your marketing and sales workflows, you ensure that high-value prospects never hit a dead end. Whether you are a mid-sized company or a large global enterprise, the platform helps you shorten your sales cycle and provide a more human buying experience for your customers.
Sierra
Sierra is a conversational AI platform that helps you transform customer service from simple chat into autonomous problem-solving.

You can ensure your AI agent stays on brand and follows your specific business logic through a robust reasoning engine. The platform focuses on high-quality, human-like interactions that reduce the need for manual intervention while improving customer satisfaction. It is designed for consumer-facing brands that need to scale their support operations without sacrificing the nuance and personality of their brand identity.
