Elyos AI replaces an outsourced answering service or an overworked office manager for plumbing, electrical, HVAC, and fire and security firms. One customer, James Frew Ltd, runs its agent through winter demand spikes of more than 500 calls a day for customer service and fault diagnostics, without adding headcount.
Elyos AI is a London startup, founded in 2023, that builds autonomous voice and chat agents for trades and field service businesses. Its six named agents answer inbound calls, diagnose faults, and book jobs directly into software like Simpro, handling over 100 calls at once without a human operator.

About Elyos AI
Elyos AI is a London company that sells AI-powered call handling and job booking software to trades and field service businesses such as plumbers, electricians, HVAC engineers, fire and security firms, and facilities operators. Founded in 2023 by Adrian Johnston, Philippa Brown, and Panos Stravopodis, the company set out to fix a problem specific to trades: missed calls and slow follow-ups that cost jobs, especially outside office hours. Elyos raised a $13 million Series A in January 2026 led by Blackbird Ventures, with Y Combinator and Pi Labs also participating, bringing total funding to $16 million after an earlier seed round. The platform runs six named agents (Out-of-hours Agent, Daytime Customer Service Rep, AI Sales Executive, Appointment Confirmation Agent, Scheduling Assistant, and Field Engineer Assistant) that can pick up a high volume of calls in parallel, diagnose faults over the phone, qualify leads, chase overdue quotes, and book jobs directly into a business's existing software. The agents act with minimal human input: they read and write job records, reschedule appointments, and close out jobs without waiting for a person to approve each step, though customers still route emergencies and edge cases to a human. Elyos does not publish which language model underpins its voice stack. It is built for small and mid-sized trades operators who cannot staff a 24/7 call center: plumbing and heating firms, electrical contractors, fire and security companies, and property or facilities management businesses. Customers such as Amax Fire and Security and Gas.Care Group report deploying all six agents across their operations, and James Frew Ltd runs its 'Jamie' agent to handle high call volumes during winter demand spikes for customer service and fault diagnostics. Elyos does not publish self-serve pricing. Every customer goes through a sales-led onboarding that starts with a demo booked from the website, and the company quotes custom pricing based on call volume and which of the six agents a business deploys. There is no published free trial or free tier. The company is expanding beyond phone into email and messaging channels and building out deeper integrations with field-service software, with international expansion beyond the UK planned for 2026. Its most recent public update was the January 2026 Series A announcement, which the company used to fund additional engineering, operations, and go-to-market hires.
Pricing
Elyos AI does not publish pricing. Every deployment is sold through a demo-led sales process with a custom quote based on call volume and how many of the six agents a business activates; there is no self-serve checkout or published free trial.
Key Features
- Out-of-hours call coverage: The Out-of-hours Agent answers calls when the office is closed, including emergency triage, so a trades business is not reliant on an outsourced overnight answering service.
- Concurrent call handling: The platform can handle over 100 inbound calls at the same time, so a busy morning or a cold-snap boiler outage does not produce a queue of missed calls.
- Fault diagnosis over the phone: The Daytime Customer Service Rep runs fault diagnostics with callers before handing off to a technician, cutting the number of calls that need a human agent.
- Direct job booking into existing software: Agents book, reschedule, and close jobs directly inside Simpro, ServiceTitan, Commusoft, HubSpot, or HighLevel, so staff do not reconcile a separate system.
- Quote chasing and lead qualification: The AI Sales Executive calls new leads within seconds of an enquiry and follows up on outstanding quotes automatically, without a salesperson dialing back manually.
- No-show reduction via reminders: The Appointment Confirmation Agent sends automated reminders that customers credit with cutting no-access and no-show rates on scheduled jobs.
Strengths
- Amax Fire and Security reports its Elyos agents handle 30% of technical calls with zero human intervention, which it credits with cutting reliance on an outsourced out-of-hours answering service.
- James Frew Ltd's 'Jamie' agent processed over 500 calls a day during a winter demand spike, covering customer support and fault triage without hiring extra staff.
- Backed by a $13 million Series A (January 2026, led by Blackbird Ventures) on top of an earlier seed round, giving it more runway than most trades-focused AI startups to keep building integrations.
- Two-way integration with Simpro covers booking, rescheduling, quote chasing, lead qualification, job notes, and PPM scheduling rather than a shallow one-way calendar sync.
Weaknesses
- Elyos does not publish which language model or speech stack powers its agents, so buyers evaluating latency or reasoning quality against rivals like NexusCall AI or Toma have to take the vendor's word for it.
- No pricing is published anywhere on the site or in press coverage; every deal goes through a booked demo and custom quote, which is friction for a small trades business trying to compare costs quickly.
- International coverage is limited: the company describes expansion beyond the UK as a 2026 plan rather than a shipped feature, so non-UK trades businesses may find local support and integrations still maturing.
Frequently Asked Questions
How much does Elyos AI cost in 2026?
Elyos AI does not publish self-serve pricing. Every deployment goes through a demo booked on the company's website, and the sales team prices each rollout around expected call volume and the number of agents in use. There is no listed monthly fee, per-call rate, or free trial anywhere on the site.
Is Elyos AI fully autonomous?
Elyos agents handle most routine calls, bookings, and quote follow-ups without a person on the line, but not every case is hands-off. Customer Amax Fire and Security says 30% of its technical calls now finish with no human involved at all, while the rest still route to a technician or office staff for parts of the job an AI should not finish alone, like a genuine emergency dispatch.
What are the best alternatives to Elyos AI?
NexusCall AI is a closer fit if you want a published, lower-commitment monthly price and bilingual call handling. Toma is built for car dealership service departments rather than trades firms. Botrelic suits a business whose support volume is mostly WhatsApp, web chat, and email rather than phone calls.
How does Elyos AI compare to NexusCall AI in 2026?
NexusCall AI publishes plans starting at $297 a month and answers in under two rings in English and Spanish; Elyos AI keeps pricing behind a sales call and does not publish a comparable response-time figure. Elyos's edge is deeper integration with trades-specific job software like Simpro and ServiceTitan, covering scheduling, PPM, and job notes rather than call answering alone.
How do you get started with Elyos AI?
There is no self-serve signup: a business books a demo through the elyos.ai website, where the team scopes which of the six agents fit the operation. Onboarding then connects the agents to the business's existing job management software, such as Simpro or ServiceTitan, before agents go live on real calls.

- NexusCall AI: Pick NexusCall AI if you want a published monthly rate and bilingual English and Spanish coverage; pick Elyos AI if you need deep two-way Simpro or ServiceTitan job-booking, not just call answering.

- Botrelic: Pick Botrelic if most of your support traffic runs through WhatsApp, web chat, and email; pick Elyos AI if phone calls and physical job scheduling drive your workflow.
