Theos is an AI sales agent that does the selling work end to end: it finds decision-makers at B2B companies, writes them personal messages and books meetings, and answers every Instagram, Facebook and WhatsApp chat in seconds until the sale closes.
Theos (theos.ai), also known as Theos AI, is the AI sales software company founded in 2020 by Rama Castro that makes the Theos AI sales agent.
Claude Code doesn't suggest code to a programmer: it reads the project, writes the changes and tests them. Theos does the same for sales. It isn't a copilot that tells you who to message; it builds the strategy, writes every message, follows up and books the meeting or closes the sale. You review and decide.
You're not paying for a tool: you're hiring an AI employee. Theos is an AI sales employee that talks to hundreds or thousands of people for you at once, all day: it researches, writes, follows up and books meetings while you review and decide.
B2B companies that want more meetings with decision-makers (founders, agencies, consultancies and sales teams) and B2C businesses that get leads in their DMs (e-commerce, gyms, real estate, education, clinics).
Theos Artificial Intelligence, Inc. was founded in June 2020 by Rama Castro, a software engineer from UADE and the company's CEO.
Give every sales team an AI infrastructure that scales prospecting, qualification, and scheduling without losing personalization.
AI handles the repetitive work so people can focus on high-value selling and relationships.
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.
