Quick answer
Pick Thoughtly if your outbound is really fast follow-up to leads you already own — its own comparison pages say plainly that it does not do cold outbound. Pick Zian AI if the motion is net-new cold contact that needs orchestration and continuous script optimisation across phone, SMS, email and WhatsApp. Thoughtly publishes pricing and a SOC 2 Type II posture today; Zian does neither, and is application-gated during beta.
How we compared
Every Thoughtly claim below comes from a page Thoughtly publishes itself — its pricing page, comparison hub, security page, languages page, Revenue Autopilot page and developer docs. Counts were taken from the raw pages, not third-party summaries, because summaries of vendor pages get counts wrong. All Thoughtly pages were checked on 30 August 2026; vendor pages move, so re-check before signing.
Where Thoughtly does not publish something, this article says “not published” rather than guessing. One note on domains: thought.ly is Thoughtly’s short-link domain. The root redirects to thoughtly.com and registered short links resolve, but an unregistered path returns the shortener’s “Link not found” page, so cite docs.thoughtly.com for documentation.
The sentence that decides most of this
Thoughtly’s own comparison hub answers the title question better than we could. Against Air.ai it says Thoughtly “converts the inbound leads you already paid for — voice + SMS + email + CRM, no cold outbound.” Against 11x.ai: “Thoughtly converts the leads you already have — voice + SMS + email + CRM. We don’t ship cold.” Against Artisan, again: “No cold outbound.”
That is a deliberate position, not a gap. Thoughtly is capable of outbound calling — its docs introduction lists inbound and outbound calls as core use cases, its pricing table lists “AI voice agents (inbound + outbound)”, and its docs cover branded calling for outbound numbers. The distinction is what those calls are for: speed-to-lead and re-engagement against contacts you already have a relationship with. Its Revenue Autopilot page describes agents that “call, text, and email every inbound lead until someone’s ready to talk.”
So the honest split is not “voice versus multi-channel”. It is warm outbound versus cold outbound. If your list is inbound enquiries, aged leads and CRM contacts, Thoughtly is built for that. If your list is people who have never heard of you, Thoughtly’s own comparison pages position it away from that work.

Where Thoughtly is the better buy
You want a price before a sales call. Thoughtly publishes one; Zian does not, and that is a real cost if you need to budget this quarter. Thoughtly’s pricing page also commits to bundling: “Voice, SMS, email, and workflows in every plan. No surprise per-channel fees, no per-seat tax.”
You need a security artefact now. Thoughtly’s security page states SOC 2 Type II with “Annual audit, continuous monitoring. Report available under NDA,” plus HIPAA with BAA and TCPA consent tracking. Zian has published no security certification. If procurement needs a report to review, that is decisive, and it favours Thoughtly.
You want to build it yourself, quickly. Thoughtly’s docs promise you can “build and deploy fully-functional voice agents in under 15 minutes—no coding required.” Its FAQ is unusually candid about fit, saying Thoughtly suits teams with “unique scripting requirements”, and adding that if you need “programmatic agent building or an embedded solution, such as for your own software solution, Thoughtly may not be the best fit.” Vendors rarely publish their own disqualifiers; that one is worth respecting.
Your motion is US inbound speed-to-lead. Thoughtly’s home ground, and its compliance material is shaped for it.
One thing not to hold against Thoughtly: channel breadth. Zian markets phone, SMS, email and WhatsApp; Thoughtly’s docs publish the same four in one omnichannel agent. Anyone telling you Thoughtly is voice-only has not read its pages.
Where Zian AI fits better
Zian’s case is narrower than vendor comparisons usually admit. It is about cold outbound, and about who operates the system.
First, the motion. Thoughtly has excluded cold outbound in writing. Zian’s SmartReach AI and PrecisionPitch AI exist for the opposite problem: SmartReach AI orchestrates message, channel and timing by country, industry and profile with intelligent follow-up pacing, and PrecisionPitch AI continuously split-tests scripts and approaches against real success outcomes. Thoughtly publishes Auto-QA and evals from its Scale tier, which grades conversations; continuous script split-testing is not published on any Thoughtly page we opened.
The second is who does the work. Thoughtly’s model is a builder you operate, with white-glove onboarding and a dedicated CSM at the Scale tier. Zian is in a partnership-application beta, so the programme is run with you rather than handed to you — no self-serve tier, no way to swipe a card at midnight. That is a trade-off, not a feature: it is slower to start and will not suit a team that wants to test on a Sunday afternoon.
Third, geography. Zian has run outbound acquisition since 2017, at one point operating campaigns for roughly a hundred businesses in the same vertical simultaneously, with a learning engine tracking around 420,000 data points across more than 10,000 leads a day. For non-US outbound that matters, because the rules differ and Thoughtly’s published compliance material is North American in shape — TCPA, state dial rules, and one non-US compliance article, on Canada’s CASL. We ran the same source-checked exercise in Zian AI vs Bland AI.
Two places Thoughtly’s own pages disagree
Checked on the same day, two Thoughtly properties give different answers. Neither is a scandal — docs drift behind marketing at most vendors — but both change the shape of a contract, so raise them on the call.
Choice of model. The pricing feature table lists “Choice of LLM (GPT, Claude, Gemini)” as included on every plan, with “Custom LLM (bring your own model)” at Enterprise. The docs FAQ says the opposite: “choosing your own language model is not supported at this time.” The docs also say custom speech-to-text and text-to-speech providers “are not supported at this time.”
How you are billed. The pricing page frames Flex as “Starts at $500 per month” with “Unlimited usage across channels”. The docs FAQ says “Thoughtly is priced on a per-minute basis, starting at just 5 cents per minute.” Those are different commercial models. Ask which governs, and get it in the order form.
The language count moves too: the languages page lists 34, the pricing page says “34+”, and the docs list 35 by including Estonian. Trivial in practice, but it is why we count from raw pages.
What we are not claiming
Thoughtly publishes performance figures on its Revenue Autopilot page — “+47% more connects”, “60s avg. speed-to-lead”, “3.2× booked meetings” — described there as results from Autopilot customers after 90 days. We repeat them as Thoughtly’s claims, not verified facts; the sample and method are not published. We could not open Thoughtly’s Trust Center, which refused our request, so we claim nothing about its contents. Thoughtly’s security page says “AWS, 4 regions” without naming them, so Australian data residency is not published either way. And Zian holds no security certification, so nothing here should be read as one.
Frequently asked questions
Does Thoughtly do outbound at all?
Yes, but a specific kind. Its docs list outbound calls as a core use case and its pricing table lists inbound and outbound voice agents. Its comparison pages then narrow that: “We don’t ship cold.” Read it as outbound to contacts you already hold.
Which one can I start using today without talking to sales?
Thoughtly. Its pricing page lists self-serve onboarding on the Flex tier and a “30–60 day pilot on Flex”. Zian has no self-serve signup and no published pricing during its partnership-application beta, so access is gated behind an application.
Are there Australian rules an AI outbound agent has to follow?
Yes, and they are stricter than many teams expect. The Australian Communications and Media Authority publishes the permitted hours: telemarketing calls are allowed Monday to Friday “9am to 8pm” and Saturday “9am to 5pm”, while on Sunday they are “not allowed”. ACMA also states that telemarketers “must not call on national public holidays”, must identify themselves and their employer, must say why they are calling, must end the call if you ask them to, and must display caller ID with a return number. Any AI dialler you buy has to respect all of that.
Does Thoughtly support Australian calling rules?
Not published. Thoughtly’s security page covers TCPA consent tracking, DNC list honouring and per-state dial rules — all United States frameworks. Its DNC glossary entry describes scrubbing against “federal and internal Do-Not-Call registries”. Its languages page lists English with no regional variants named, and we found no mention of ACMA or the Australian Do Not Call Register on any Thoughtly page we opened, nor an Australia-specific page in its published sitemap. That is a documentation gap, not proof of non-compliance, so ask them directly.
Is Zian more secure than Thoughtly?
No, and on published evidence the reverse is true. Thoughtly publishes a SOC 2 Type II posture with reports available under NDA, plus HIPAA and BAA options at Enterprise. Zian publishes no security certification. Zian does offer private model deployment on customer infrastructure; Thoughtly lists dedicated infrastructure and data residency at its Enterprise tier. If a certificate is the requirement, Thoughtly is the one that has published one.
How many integrations does Thoughtly really have?
Its pricing page claims “200+” native integrations. Its public integrations directory names 24 tools, counted from the raw page on 30 August 2026, and one of those is Zapier, which its own listing describes as reaching “5,000+ apps”. Both numbers can be true depending on what you count; if a specific system matters to you, confirm it is one of the named 24 rather than assuming.
Choosing
The test is one line. If the people you are calling already raised their hand, Thoughtly is purpose-built for that and publishes the price and security posture to prove it. If you are opening cold conversations at volume, in markets with their own rules, and you want message, channel, timing and script optimised continuously against booked outcomes rather than assembled once in a builder, that is what Zian is for. Our roundup of the best AI voice agents for outbound calls covers the wider field if neither fits.
Zian AI is in partnership-application beta: limited places, and a conversation before access. If cold outbound is your problem, Apply For Partnership and we will tell you honestly whether it is a fit.
