## DOO

DOO positions itself as more than a chatbot layer. The pitch is that agents should finish the job rather than only answer questions: an agent detects intent, checks the customer's record in your systems, executes the workflow (issuing a refund, moving a booking, replacing a missing item), and reports back in the customer's own language. All of this runs through a single unified inbox where WhatsApp, Instagram, email, web chat, SMS, and voice conversations are threaded per customer with the full history attached.

Setup is deliberately frictionless. You enter a website, work email, or company name, and DOO reads the public information about your business to assemble a working agent you can test on real questions before speaking to sales. A no-code builder called CTRL lets teams train, correct, and govern each agent, while analytics surfaces quality scores, SLA drift, and early warnings on at-risk customers. Language handling is a core strength: the platform understands slang, accents, and mixed-language messages, and switches language whenever the customer does.

Pricing is quoted per engagement — DOO uses a "Book a demo" and enterprise sales motion rather than self-serve tiers, so contract values and seat counts are not published. Publicly cited results include tens of millions of agent replies, roughly 79% automated conversation resolution, and markedly faster first-response times. DOO is a Bahrain-rooted company that has drawn strategic investment and partnership attention across the Gulf, with customer references spanning telecom, delivery, and banking.

**Pricing & Plans:** Pricing is model-led rather than published: DOO runs a demo-and-quote sales process with a free trial available and no credit card required to start. Plan pricing, usage limits, and channel allocations are given on request.

- **Unified omni-channel inbox:** WhatsApp, Instagram, email, web chat, SMS, and voice all land in a single threaded queue, merged per customer with every past conversation attached.
- **Action-taking AI agents:** Agents run connected workflows such as checking an order, starting a refund, or moving a booking, with human approval gates you configure for sensitive steps.
- **Multilingual, code-switching conversation:** The agent understands slang, accents, and mixed-language messages, and switches languages mid-conversation when the customer does.
- **No-code agent control center:** Build, train, and correct every agent in CTRL, with quality auto-scored on every conversation and coaching alerts when tone or SLA slips.
- **Voice and analytics:** Inbound calls join the same queue as chats with full transcripts, while dashboards report CSAT, resolution rates, and at-risk VIP escalation.

**Strengths:** Genuinely action-oriented agents that write to back-end systems rather than only answering FAQs; Strong multilingual and dialect handling, which suits Gulf and other mixed-language markets; Everything lands in one inbox with per-customer threading, reducing duplicate work; Fast deployment path: type a website and test a working agent before any sales call

**Limitations:** No public pricing tiers, so budgeting requires a sales conversation; Enterprise-led rollout means smaller teams may find onboarding heavier than a self-serve product; Value depends on connecting your internal systems, which requires integration work

## 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.
