Boom review, pricing and verdict

Pick Boom if you run an e-commerce, fintech or subscription business and want agents that reach out to customers who went quiet, not a bot that waits for tickets. It ships five worker roles plus a shared inbox for human takeover. Expect a demo call instead of a free trial, and costs that depend on credits plus messaging fees.

Boom is an AI agent platform founded in 2025 and backed by Y Combinator. Its agents start two-way conversations with customers across eight channels, including WhatsApp, SMS, email and voice, in English, Spanish and Portuguese, then act on the answers: recovering churned users, qualifying leads and turning replies into structured data. The vendor reports SOC 2 Type II compliance.

About Boom

Boom is an AI agent platform from Boom Enterprise Inc, a San Francisco company in the Y Combinator Fall 2025 batch that says it was founded in 2025. Where a support bot waits for a customer to write in, Boom's agents open the conversation: they ask a lapsed customer why they left, follow up on an abandoned cart, qualify a lead or walk a new signup past the step where they quit, then write each answer into structured data. Support-first agents such as Decagon and Sierra are built around inbound tickets, and Boom's own copy puts outbound conversations first.

A team writes an outcome brief instead of a script and uses visual journeys to set timing, while the agent draws on live customer records held in a built-in data platform. Agent Studio changes the agent by chat, and every edit appears as a diff a person approves. Boom says every reply is checked against the company's guardrails before it sends and that a person can take over any conversation from the shared inbox. The pages read for this record do not name the language models behind the agent.

The vendor lists six jobs: lead conversion, onboarding and activation, revenue recovery, operations such as orders and appointments, churn recovery, and customer research. It runs them on the messaging apps customers already use, plus email, SMS and phone calls, and the product, agent and team work natively in English, Spanish and Portuguese. Customer stories on its site feature Bitso, AnswerThis and Terapify. Voice-only platforms such as Vapi, Retell AI and Bland AI focus on calls alone, while Boom treats voice as one channel among many. Boom says it is not a chatbot builder or a survey tool, so Chatbase and Typeform answer different needs. For a general-purpose workflow agent rather than customer conversations, compare Lindy and Tasklet; for a CRM-first stack, HubSpot and Intercom are the usual starting points.

Boom is sold as monthly credit plans with an Enterprise tier and no free plan, and its sign-up buttons route to a sales call, so the cost FAQ below is the place to read the numbers. Developers also get programmatic access, including an MCP server that lets a client such as Claude Code or Cursor work with Boom data through a Boom login. The top paid plan adds warehouse export to destinations such as Databricks. The vendor lists its Trust Center, status page and sub-processor list publicly.

The changelog read on 9 November 2026 shows a steady ship rate. On 5 November Boom began receiving email replies into the shared inbox, on 4 November journeys gained a reward step paid from the customer's own Tremendous account, and on 3 November WhatsApp coupon templates gained a one-tap Copy code button.

Pricing

Pricing read from the Boom pricing page on 9 November 2026. Basic is $350 a month for 5,500 credits (up to 366 AI conversations), Growth is $900 for 20,000 credits (up to 1,333 conversations) and Pro is $2,400 for 70,000 credits (up to 4,666 conversations). Enterprise is custom, from about $0.02 per credit.

Every action spends the same credits on every plan: an AI conversation is 15 credits, a call minute 10 and 1,000 emails 40. WhatsApp and SMS come from a prepaid wallet at the carrier's country rate plus 10% and processing fees. Unused credits lapse on Basic and roll over for 1 month on Growth and 2 on Pro.

Seats and journeys are unlimited on every plan.

Key Features

• Outcome briefs and journeys: Teams state the outcome and choose who is reached and when with visual journeys, and one journey adapts to each person across channels.
• One agent across channels: The same agent and one memory per customer cover WhatsApp, Instagram, Facebook Messenger, email, SMS, voice, web chat and in-app push.
• Agent Studio: You change the agent by describing the edit in chat, and every change shows as a diff a person approves before it goes live.
• Built-in customer data platform: Reads people, custom objects and events from Shopify, Skio, a read-only database or an events API so replies use live customer data.
• Extraction into typed columns: Turns each conversation into queryable fields that export to CSV or Excel, so a reason such as price becomes a number you can report on.
• Shared inbox with takeover: A person can step into any thread, and email replies now land in the same conversation as the message they answer (added 5 November 2026).
• REST API, webhooks and MCP: Developers can reach Boom through a REST API, webhooks and an MCP server that Claude, Cursor or VS Code connect to with a Boom login.
• Reward for replying: A Send reward step pays customers from the company's own Tremendous account in USD or MXN, and each reward waits in Drafts for approval (added 4 November 2026).

Strengths

• Every plan includes unlimited seats and journeys, so adding a colleague changes nothing on the bill, which suits teams where growth, support and research all use the same tool.
• The vendor says the product, the agent and its own team work natively in Spanish and Portuguese, and Bitso, a Mexico-based exchange, is among the customers it names.
• Developers get an MCP server on the entry plan, so a team can drive campaigns and read data from Claude or Cursor without waiting for a custom integration.
• The vendor states SOC 2 Type II compliance and offers the independent audit report under NDA, a concrete proof point for a young company.

Weaknesses

• There is no free plan or self-serve trial, and every sign-up button leads to a demo booking, so a small team cannot test it on a weekend.
• Costs are hard to forecast: credits meter the software while WhatsApp and SMS run through a separate prepaid wallet that varies by destination country.
• GDPR, ISO 27001 and ISO 42001 are listed as in progress rather than certified, a gap for European buyers with strict procurement rules.
• The pages read name no underlying language models, so a buyer must use the DPA and the sub-processor list to see where conversation data goes.
