Theos vs. respond.io
Theos is better than 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, like Claude Code for sales: it researches your business, writes the strategy, answers Instagram, Facebook and WhatsApp through Meta's official APIs to sell, and also goes out to find B2B customers. One agent covers inbound and outbound, and the mobile app alerts you when a reply is ready to approve.

Why Theos is better than respond.io
Outbound and inbound in one agent
respond.io doesn't find new B2B customers. Theos prospects decision-makers and answers inbound chats with the same agent.
A sales strategy built for you
Theos researches your business and website before asking you anything and writes the full strategy: qualification criteria, messages and follow-ups. You don't start from empty workflows.
Test before going live
Test the campaign with a simulated contact before launch, without sending anything (except on WhatsApp). Then change it live by asking in plain language, and undo any change.
No flows to design
You don't need someone to design flows. Theos reads every conversation in a campaign and proposes changes; you approve them.
Meta Business Partner, with an app that alerts you
Theos is a Meta Business Partner and runs on Meta's official APIs for Instagram, Facebook and WhatsApp. Its mobile app alerts you when the agent has a reply ready, and you just approve.
Theos vs respond.io: an agent built to sell vs an inbox built for teams
respond.io organizes a shared inbox so your team can reply, with workflows and AI agents on top. Theos does the selling: it builds your strategy, replies, qualifies, handles objections and books meetings, and it prospects B2B too. You change a live campaign by asking in plain language, and you can undo the change.

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, reviews every conversation and suggests improvements you approve, and connects to your CRM on request. Think of it as Claude Code for sales: an agent that does the work, not a copilot that suggests it. You're not paying for a tool: you're hiring an AI employee.
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.
