Adding Zeus to our website quite literally increased our Decisions in Principle by 10X! It’s the single best change we’ve ever made to our marketing and sales process.

Zeus gives us credibility at a time when many competitors don’t have 24/7 support. It’s not just a generic tool, the team worked collaboratively to tailor the product for our business, and that commercial enthusiasm is rare.

Zeus is a game-changer. We’ve worked with other chatbots, and none come close to how intuitive and brand-aligned Zeus is. It qualifies leads faster, saves time, and becomes a true extension of your brand, with the patience of a saint.

Ensuring Momentum Mortgages stands out from the competition meant researching and investing in adding AI to my business in order to provide the best customer experience possible. When clients come to my website it’s important we support them 24/7, and I’m delighted in how Zeus does this for my customers.

We’re flying on customer care and client retention, with a 54% engagement rate through Zeus. In month one alone we booked over 200 appointments against 400 leads, and because it all goes out at the same time the response is on a different level. Speed matters in what we do, and it’s worked really, really well.
Ian Bush
Managing Director
Mortgages First
We used to complete on around 42% of our anniversary opportunities, and this year we’re up to about 67%. Zeus has really helped with that, reaching people we’d never have spoken to and getting more of them in front of advisers, where we convert around 80%. The booking team were apprehensive at first, but now they love it.
Mike Kenney
Regional Sales Director
Embrace Financial Services
We’re definitely getting more engagement and more enquiries with Zeus than we would without it. The conversations capture really good information, which makes it far easier to route each lead to the right adviser, rather than a form fill that tells us very little. Sam and the team have been great to deal with, fixing anything immediately.

Zeus follows up with every lead by text the moment they come in, so I know nobody slips through the cracks. By the time we get someone on the phone they’ve usually already watched our kids’ programme video and they’re excited about it. Every lead gets contacted, and every lead feels heard.

Email vs Message
Channel matters as much as content. The best marketing copy is wasted if no one opens it, and email open rates can't compete with WhatsApp and SMS, where messages get seen and read in minutes. As inboxes get noisier, meeting customers where they actually spend time is what determines whether your message lands at all.

Zeus keeps nudging with valuable follow-up, and the highest engagement often comes after a customer has already ignored initial messages. Most teams stop chasing after a couple of weeks of voicemails and chaser emails, especially on products with long sales cycles. That persistence is exactly where the uplift in renewals comes from.

Zeus AI is a well-funded platform benefiting from over £2m+ invested into core technology, complemented with experienced forward-deployed engineers providing boutique implementation.
Zeus sets the standard for secure, compliant, and intelligent business automation, perfect for CTOs seeking robust data protection, transparent oversight, and expert technical support.
Zeus has been iterating on reliable agent creation since 2023.
Setting up your agent works like training a new staff member. We start by understanding your offer and call to action. From there, we build a sales script and conversation flow so the AI can handle calls like a real phone agent.
This involves connecting it to a custom knowledge base about your business, training it on common objections, and setting clear guardrails for how it responds.
Once trained, we link the AI to your Meta Business account, set up a new phone number, and begin reaching customers via WhatsApp. Our team monitors conversation quality and keeps iterating to improve performance and conversions.
We run a working session with you to train the AI so it sounds exactly right for your business.
A new mobile number used only for Zeus AI, keeping customer messaging organised and professional.
We connect the number through Meta Business Manager so Zeus can start conversations on WhatsApp.
Upload a contact list (first name, mobile number, plus optional fields).
Zeus builds and runs the AI nurture on WhatsApp or SMS.
When contacts are ready, Zeus routes them into your booking link or notifies your team.
Zeus AI Ltd is a London-based technology company that specialises in setting up AI agents that nurture contacts and book calls for your team. Conversations run on WhatsApp, website live chat, and SMS.

AI makes it easy for your customers to ask questions and learn more about your brand. Adding a Zeus AI agent to your website makes it accessible for customers and creates a huge uplift in total enquiries.
No. Zeus AI uses the latest OpenAI models, but the product is not a model wrapper. Zeus includes workflow logic, guardrails, integrations, and a custom knowledge layer so replies are grounded in the client's business context.
Zeus AI uses the latest OpenAI models and upgrades as better models become available. The architecture is model-agnostic, so model changes do not require rebuilding client workflows.
Zeus runs automated prompt tests at volume, then iterates prompts, flows and guardrails. Business-specific answers use the client's knowledge. If the information is not available, Zeus is designed to say it does not know rather than invent an answer.
Zeus is built for enterprise use and supports corporate security and procurement reviews, including data protection, encryption, logging, and data segmentation between clients.
Zeus AI supports GDPR requirements, including consent handling, access, and erasure workflows.
A pilot can start from a CSV of leads. Production use can ingest leads through the API and send outcomes through webhooks into a CRM. Diary booking links and lead-state rules are supported.
Zeus can engage contacts, qualify intent, answer approved business questions, nurture leads, and book calls.
Clients get onboarding and rollout support. Larger deployments can include structured account management.
A user is treated as opted out when they clearly ask for contact to stop, including STOP and similar wording, or when they say they are the wrong contact and do not want further messages.
Zeus is used to book meetings. WhatsApp engagement is typically higher than email when the sales script is clear.
The sales script is reviewed with the client before launch, then rolled out in small batches so real conversations can be checked and refined.
Zeus is designed so the client team does not have to build an internal AI tool. Operational lift is kept low.
Zeus can book calls without the client team logging in to manage WhatsApp conversations. Their main work is handling the booked calls.
Zeus provides a reporting dashboard and exportable CSV files that can be checked against the client's CRM.
No. Zeus is service-led. Messages are transactional and behaviour triggered, not promotional blasts.
Messages carry a clear opt-out. Opt-outs are honoured, logged, and synced with other channel preferences.
Comparable deployments cited on this FAQ show 3% opt-out and 1% complaint rates, with WhatsApp outperforming email on the same use case. Zeus starts with one narrow, high-value flow.
Yes. Zeus recommends a scoped, reversible pilot on a single use case, with agreed metrics and a stop trigger.
