Its site describes a "Human + AI" model: AI handles account research and prioritization, while its own people make calls, qualify interest and set appointments. Service lines include appointment setting, SDR outsourcing and sales prospecting, account-based marketing, demand generation, webinar and event follow-up, and cross-border lead generation with multilingual campaigns. It runs campaigns through its own platform, which the site calls Smart Engage in one place and Pipeline in another, and it sells a Global GTM Assessment for companies entering new markets.

It runs campaigns in North America, Europe and the UK, Asia-Pacific, Southeast Asia and Latin America, with outreach in languages such as Thai, Bahasa, Vietnamese, Mandarin, Spanish and Portuguese. That makes it relevant for companies selling across several regions. The site does not set a company size range, though it shows logos of large enterprises. - Its company profile says Callbox was founded in 2004 and is headquartered in Encino, California. - Its company profile lists 700+ full-time staff and six offices across the US, Australia, Singapore, Malaysia, Colombia and the Philippines. - Its company profile claims 15,000+ companies served across 50+ markets and 10,000+ campaigns run. - Its site shows a Clutch Top Lead Generation Company 2026 badge, a G2 Grid Leader badge for Spring 2025 and a HubSpot Gold badge. - Its homepage cites ratings of 5.0 on Clutch (100+ reviews), 4.4 on G2 (90+ reviews) and 4.5 on Google (85+ reviews). ## How Callbox works Its homepage lays out four stages: Intelligence (finding accounts), Coordination (connecting outreach across channels), Conversation (qualifying and booking) and Progress (handing over context and learning from results). Outreach runs across email, LinkedIn, phone, web, chat and events. The site says the client's CRM stays the sales source of truth and the client's reps own and close the opportunity. Each pricing pod includes one dedicated SDR, a multi-channel cadence, AI-enriched contact data, campaign manager oversight and weekly reporting. The broader team around a pod includes copywriters, data research analysts, QA specialists and an account strategist, and the pricing page says its Callbox Pipeline CRM, a sequencing engine, deliverability infrastructure and a real-time dashboard are included. Its company profile names Rom Agustin as CEO and Rebecca Matias as COO, along with VPs for business development, sales and marketing, and North America. It gives Encino, California as headquarters and 2004 as the founding year. Founders are not named. ## Published results and clients These are Callbox's own claims from its website. We have not verified them independently. - Its case study says a 12-month US logistics campaign produced 146 sales appointments and 500+ MQLs. - Its case study says a four-month campaign for an enterprise managed services provider produced 70 SQLs and 140 MQLs. - Its case study says a three-month office and workplace solutions campaign produced 57 sales appointments. ## Engagement and pricing Its pricing page estimates $6,667 a month per Campaign Pod. The page says exact pricing is set after a consultation and varies with industry, geography, sales cycle and campaign goals. Engagements are subscriptions that scale by adding pods. Contract length, minimum term and any setup fee are not stated; the page says these are covered in the consultation and that there are no hidden fees. ## Callbox strengths and trade-offs Strengths, based on what its site publishes: - Publishes an estimated price per Campaign Pod - Multilingual campaigns across five regions - Long operating history, founded in 2004 - Pods include a dedicated SDR and campaign manager Trade-offs to weigh: - Contract length and minimum term are not published - Exact price is set only after consultation - Runs campaigns on its own platform, so check how data flows into your CRM ## How Callbox compares Outsourced SDR firms rent you trained reps, usually with cold calling at the center, and are measured on booked appointments. The real differences are whether reps are dedicated or shared, onshore or offshore, how long the minimum term is, and who owns the data and call recordings when the contract ends. Ask how a qualified appointment is defined before you compare prices. Callbox suits companies that want a staffed, multi-channel calling and email operation, especially across several countries or languages. The published per-pod estimate gives a useful starting budget, so ask what one pod realistically produces in meetings for your segment, what the contract term and notice period are, and whether the included CRM is required or can be skipped in favour of syncing to your own. Ask to speak with the dedicated SDR and campaign manager before signing. Teams that want to own their outbound tooling may prefer a build-and-handover provider. ## Callbox vs. OneGTM | | Callbox | OneGTM | | --- | --- | --- | | Type | SDR outsourcing and appointment setting firm | Founder-led GTM engineering practice | | Focus | Outsourced B2B lead generation, appointment setting and SDR firm founded in 2004. | Outbound, signals, enrichment, RevOps, and AI systems built in the client's own accounts | | Pricing | Its pricing page estimates $6,667 a month per Campaign Pod. | Scoped on a call | OneGTM wrote this profile and competes in the same market, so weigh the comparison with that in mind.
