## Ringmere

Ringmere replaces the voicemail-and-missed-call problem with an AI receptionist that answers every call on the first ring. You keep your existing number or take a new UK local number, teach the assistant your services, prices, opening hours and FAQs — by importing from a website, PDF, spreadsheet or even a photo of a price list — and approve everything before it goes live. Calls are answered 24/7, transcribed and summarised, and booking confirmations, reminders and missed-call text-backs go out automatically.

The product is built for businesses that live on their phone: salons, barbershops, dental and aesthetics clinics, physio, vets, garages and MOT centres, plumbers, restaurants, takeaways and hotels. On higher tiers it also answers WhatsApp and SMS in two-way AI chat, drafts replies to customer emails, routes calls to up to five departments or an unlimited number of teams, and syncs hotel room bookings with channel managers such as Beds24 and Cloudbeds.

Ringmere emphasises control and compliance: it only uses services, prices and answers you have approved, checks live availability to avoid double bookings, and escalates vulnerable or urgent callers straight to a person. Customer records are stored in the UK, with GDPR readiness, encryption and an AI-and-recording disclosure switched on by default. Pricing is month to month with no long contract: Starter at £49, Growth at £99 and Pro at £249 per month excluding VAT, each with included minutes, extra minutes at £0.25/min (or £0.20 on Pro), and a 7-day free trial. White-label reseller plans are available for agencies, franchises and multi-location groups.

**Pricing & Plans:** Monthly subscription plans, prices exclude VAT: Starter £49/month (150 call minutes), Growth £99/month (240 minutes across calls and chat), Pro £249/month (700 minutes). Extra minutes £0.25/min, £0.20/min on Pro. Every plan includes a UK phone number, a 7-day free trial and month-to-month billing. Agency/Enterprise white-label pricing on request.

- **24/7 call answering:** Answers on the first ring day and night with a real-time, speech-to-speech voice that holds a natural conversation instead of sending callers to voicemail.
- **In-call calendar booking:** Books, reschedules and cancels appointments against live availability in Google Calendar or Outlook, plus table reservations, takeaway orders and hotel room bookings, so the same slot is never promised twice.
- **Lead capture and human handoff:** Asks who is calling and what they need, logs it against the call, and escalates emergencies, complaints and vulnerable callers to your team with full context.
- **WhatsApp, SMS and email replies:** On Growth and Pro, two-way AI chat on WhatsApp and SMS handles bookings and questions, and every customer email gets a drafted reply for you to send.
- **Transcripts, alerts and compliance:** Calls are transcribed and summarised on a dashboard with recovered-revenue tracking; owner alerts and daily summaries arrive on WhatsApp, and GDPR-ready records are stored in the UK with disclosure on by default.

**Strengths:** Answers calls 24/7 without hardware, engineers or scripts to write; Books into Google Calendar or Outlook using live availability, avoiding double bookings; Clear, published UK pricing from £49/month with a 7-day free trial and no long contract; Compliance-focused: UK data storage, GDPR readiness and AI/recording disclosure on by default

**Limitations:** Focused on UK businesses with UK phone numbers; international number support is still described as coming; Extra minutes beyond your plan allowance are billed at £0.25/min (£0.20 on Pro); Free trial availability is restricted to UK cards that have not used a Ringmere trial before

## Sierra

Sierra is a conversational AI platform aimed at businesses that want to improve customer experience and grow customer lifetime value. Instead of static chatbots, Sierra focuses on AI agents that can hold natural conversations, take actions through connected systems, and adapt over time. The company describes its offering as the leading conversational AI platform for businesses, used by large brand-name enterprises across sectors such as financial services, healthcare, telecom, media, travel and hospitality, retail, technology, and the public sector.

A central feature is Ghostwriter, an agent-building agent that can take unstructured input — standard operating procedures, transcripts, whiteboard photos, or audio recordings — or a plain-English goal, and turn it into a production-ready, multilingual, multichannel agent with built-in guardrails. Around it sits a set of operating tools: Insights Explorer for deep, research-style analysis of agent performance, Monitors that flag conversations needing attention, Experiments for multivariate testing of conversation design, and Observability that exposes tool calls, knowledge lookups, and latency. Horizon adds long-horizon planning, customer context memory, outcome optimization, and proactive engagement triggered by real-world signals.

Sierra deploys a single agent across chat, SMS, WhatsApp, email, voice, and ChatGPT, so customers get consistent help on the channel they prefer. Trust, security, and compliance are emphasized, including a public Trust Center. Notably, Sierra prices on outcomes rather than seats: the company states customers pay for a job well done, aligning cost with the value the agent delivers.

**Pricing & Plans:** Outcome-based pricing: Sierra states that customers pay for results delivered rather than per seat. Specific rates are not published and require contacting Sierra.

- **Ghostwriter agent builder:** Turn SOPs, transcripts, whiteboard photos, audio recordings, or a plain-English goal into a production-ready, multilingual, multichannel agent with built-in guardrails.
- **Omnichannel deployment:** Run a single agent across chat, SMS, WhatsApp, email, voice, and ChatGPT so customers get consistent help on their preferred channel.
- **Analytics and observability:** Insights Explorer, Monitors, Experiments, and Observability surface agent performance, flagged conversations, and every tool call, lookup, and latency event.
- **Horizon long-horizon planning:** Breaks complex outcomes into steps that improve over days or months, with customer context memory and proactive engagement triggered by real-world signals.
- **Outcome-based pricing:** Pay only for the value Sierra delivers, aligning cost with completed customer outcomes instead of seats or licenses.

**Strengths:** Ghostwriter builds production-ready agents from SOPs or plain-English goals, lowering the barrier to launching.; Single agent spans chat, SMS, WhatsApp, email, voice, and ChatGPT for consistent cross-channel support.; Outcome-based pricing ties cost to delivered results rather than seats.; Strong operational tooling for analytics, experiments, and observability of live agents.

**Limitations:** No published price list, so budgeting requires a sales conversation.; Enterprise-oriented positioning may be heavy for very small businesses.; Deep capabilities like Horizon and Context Engine assume integration with existing systems to reach full value.
