Theos vs. respond.io
respond.io is an omnichannel inbox for teams, with workflows and AI agents across WhatsApp, Instagram, Messenger, TikTok, email and calls. Theos is an AI sales agent: it answers those chats to sell, and it also goes out to find B2B customers, so one agent covers inbound and outbound.

Frequently Asked Questions
Theos is an AI sales agent. For B2B, Theos does your cold outreach: it reaches decision-makers on B2B social networks, writes personal messages in your voice, follows up, handles objections and books qualified meetings on your calendar. For B2C, it answers every Instagram, Facebook and WhatsApp message in seconds, qualifies the lead and closes the sale in chat.
Most tools send messages. Theos sells. It builds a strategy around your product or service, holds real conversations, qualifies each lead and books the meeting or closes the sale. One agent covers outbound and inbound, learns from every reply and keeps your CRM in sync. Think of it as Claude Code for sales: an agent that does the work, not a copilot that suggests it.
On Instagram, Facebook and WhatsApp, Theos runs on Meta’s official APIs, so your accounts connect exactly the way Meta intends. B2B social networks are different: each sets its own rules and can limit accounts it sees as too active. There, Theos keeps activity conservative, lets you approve messages before they go out and pauses when an account needs attention. No one can promise a network will never restrict an account, so how you use yours is always your call.
B2B companies that want more meetings with decision-makers: founders, agencies, consultants and sales teams. And B2C businesses that get leads in their DMs, like e-commerce, gyms, real estate, education and clinics, and want every chat answered and sold.
It depends on your industry and your product or service, but Theos is built for one outcome: more clients and more revenue. We’ve used it to book meetings with teams at Ford, BMW, Salesforce, HubSpot and L'Oréal.
Tell Theos what you sell or paste your website. It builds your strategy, you review it, connect your channels and go live. Advanced plans include onboarding sessions with our team to set up and tune your first campaigns.
