Clearbit vs Thena: Which Is Better in 2026?

Clearbit (now part of HubSpot) is a B2B data and enrichment platform that helps companies enrich their contact and account records with accurate company and person details, identify website visitors, and power smarter sales and marketing. By turning a single piece of information — like an email or a company domain — into a rich profile of firmographic and contact data, Clearbit helps teams understand who their leads and customers are, qualify and route them effectively, and personalize their outreach and marketing.

The platform's core capability is data enrichment: given limited information, it appends details such as company size, industry, location, role and more, filling in the gaps in your CRM and marketing systems so records are complete and useful. Beyond enrichment, Clearbit offers capabilities like identifying anonymous website visitors (revealing which companies are showing interest), real-time enrichment of form submissions to shorten forms and improve data quality, and intelligence that supports lead scoring, segmentation and targeting. This data foundation helps sales and marketing teams work more precisely and efficiently.

Clearbit is widely used by B2B sales and marketing teams that depend on accurate, complete data to qualify leads, personalize campaigns, route prospects to the right reps, and understand their pipeline and audience. Its integration into the broader sales and marketing stack — including its connection to HubSpot — makes enriched data available where teams already work. As B2B go-to-market increasingly relies on good data for targeting and personalization, enrichment and intelligence platforms are an important part of the stack. For B2B teams that want to enrich their data, identify interested companies and power more precise, personalized sales and marketing, Clearbit offers a powerful, well-established and widely-trusted solution — used in accordance with applicable privacy regulations.

Thena is a customer support and operations platform built for B2B companies that support their customers through shared Slack and Microsoft Teams channels. As more B2B relationships move communication into Slack Connect and Teams channels, support requests, questions and issues increasingly come through chat rather than traditional ticketing — and managing that effectively is hard. Thena turns these conversations into a structured, trackable, AI-assisted support workflow, so nothing gets missed and teams can deliver excellent, organized support where their customers actually talk to them.

The platform sits on top of your shared channels and helps you manage them like a real support operation: detecting and tracking requests, assigning and prioritizing them, ensuring timely responses, and giving visibility into what's happening across all your customer channels. It uses AI to help triage and respond, surface insights, and reduce the manual overhead of keeping up with many conversations. By bringing ticketing-like structure and intelligence to chat-based support, Thena solves a real problem for B2B teams whose customers expect to reach them in Slack or Teams but who need the accountability and tracking of a proper support system.

Thena is aimed at B2B SaaS companies and others whose customer relationships and support happen heavily in shared messaging channels, and who want to manage that professionally rather than letting requests slip through informal chats. It connects to the broader support and CRM stack so customer context and data flow where they're needed. As B2B communication continues shifting into Slack and Teams, and as AI makes managing those conversations smarter, platforms that bring order and intelligence to channel-based support are increasingly valuable. For B2B companies that support customers in Slack or Teams and want a structured, AI-assisted way to manage it, Thena offers a focused, modern and genuinely useful solution.
