What Is Certainly AI and What Does It Cost? (2026 Guide)

Certainly AI is a Copenhagen company, founded in 2017, that sells multi-model AI agents for ecommerce and D2C support, and its pricing page, captured on 15 September 2026, listed three plans: Starter at €500 a month for 2,000 conversations, Pro at €1,250 for 10,000 and Enterprise from €2,500 for 40,000. On 24 September 2026, certainly.io did not resolve at all (its name servers refused DNS queries), so those prices come from the 15 September capture and could not be re-checked on the live page.

We build AI agents for customer service ourselves, so this is written by people who have to evaluate platforms like Certainly in practice. We worked from Certainly's own pages rather than a review aggregator.

What is Certainly AI?

Certainly was founded in 2017 in Copenhagen (its site lists the legal name Certainly A/S and a Copenhagen address) and, per its own homepage, has deployed 1,000+ AI agents that have handled a live-updating count of tens of millions of queries (over 72.6 million at the time of this screenshot). The pitch leads with implementation risk instead of feature breadth: the homepage says plainly that "most AI projects stall," and positions Certainly's agents as ones that "go live, and stay loved." That framing is aimed at a buyer who has already been burned by one failed AI pilot and is shopping for reassurance as much as for features.

The 2017 founding date matters. Most of the "AI agent" category only started after large language models became commercially usable around 2022 and 2023. Certainly predates that by five years, so its early years went into rule-based and NLU chatbots before generative AI was layered on top. That history shows in the product today as a multi-model, multi-channel platform rather than a single-model wrapper built during the recent boom.

Named customers with published results include Feastables (the MrBeast chocolate brand), where Certainly's agent is credited with 6.5% of total revenue and a 20% higher average order value on post-chat purchases; Fintiba, which reports a 97% chat containment rate with 24/7 multilingual support; and Quad Lock, which reports a 43.4% resolution rate and 5x agent productivity. Other named clients include Ticketmaster, McDonald's, and GANNI. These are Certainly's own case-study figures, and Certainly doesn't cite an independent audit of them. The range of brand sizes, from a DTC phone-mount company to a McDonald's-scale enterprise, does suggest the product spans different deployment sizes.

How does Certainly's AI work?

The mechanism worth understanding first is Certainly's multi-model architecture. Instead of building on a single LLM, Certainly natively supports Claude, Gemini, and GPT, plus more than 200 additional models through OpenRouter, with what it calls "zero lock-in." A team isn't betting its support automation on one model vendor's pricing or availability. If a model gets deprecated or a better one ships, the agent framework doesn't need rebuilding around it.

On top of that model layer, Certainly's agents are built to "reason, act, and resolve" a conversation end to end instead of answering a question and stopping. That's the difference between a chatbot that tells a customer where to click and an agent that looks up an order, applies a discount, or processes a return inside the connected systems.

Channels and integrations

Certainly deploys across web, Meta (WhatsApp and Messenger), SMS, email, and voice, and connects to more than 50 pre-built integrations spanning ecommerce, CRM, help desk, and marketing platforms, per its own site. That breadth matters for the DTC brands Certainly names as customers, since one shopper's journey with a brand like Feastables or GANNI often spans an Instagram DM, a website chat widget, and a follow-up email. Certainly's pitch is one consistent agent answering all three.

Security and compliance posture

Certainly states it is GDPR compliant with EU data residency, SOC 2 aligned, and backed by a 99.9% uptime SLA. "SOC 2 aligned" is not the same as holding a SOC 2 report, so ask for the audit if your security review needs one. The EU data residency detail matters for the Fintiba case study (a German fintech) and any European financial-services buyer where data location is a compliance requirement.

What features does Certainly include?

• Multi-model AI: native support for Claude, Gemini, and GPT plus 200+ models via OpenRouter.
• Multi-channel deployment: web, Meta, SMS, email, and voice.
• 50+ pre-built integrations across ecommerce, CRM, help desk, and marketing platforms.
• AI reporting, tracking revenue influenced, resolution rate, and CSAT.
• GDPR compliance and EU data residency, plus SOC 2 alignment.
• 99.9% uptime SLA, with custom SLA terms and uptime credits on Enterprise.

How much does Certainly AI cost?

The pricing page we captured on 15 September 2026 listed euro prices, billed annually, excluding VAT and sales tax, and said the company is "trusted by 200+ CX teams," with logos including BetVictor, HUG, Joseph Joseph, and Entain. This is a recent change: an archived copy of the same page from March 2026 showed no prices at all, only "Contact us" buttons and annual conversation caps (Starter up to 24k a year, Professional up to 120k, Enterprise up to 300k). Because certainly.io was unreachable on 24 September 2026, confirm these figures with Certainly before you budget:

The per-conversation rate halves at each tier: roughly €0.25 on Starter, €0.125 on Pro, and €0.0625 or less on Enterprise. That's a real volume discount, and it tells you what Certainly wants: bigger annual commitments. A team's actual cost per resolved conversation depends on which tier its volume lands in, and on how many of those conversations the agent resolves rather than hands off.

Every plan runs as a 3-month pilot with 7-day cancellation notice, and Certainly notes annual billing over quarterly saves roughly 25%. Payment runs by bank transfer or credit card via Stripe, with a 5% surcharge on card payments.

What are Certainly's pros and cons?

Pros

• Per-conversation pricing with a clear volume discount, published as of the 15 September 2026 capture.
• Multi-model architecture avoids single-vendor LLM lock-in.
• Named case studies spanning a wide range of company sizes, from DTC brands to Ticketmaster and McDonald's.
• GDPR compliance and EU data residency, relevant for European and regulated buyers.
• Multi-channel reach: web, Meta, SMS, email, and voice from one platform.

Cons

• Entry pricing (€500/month for 2,000 conversations) is higher than the self-serve tools in this category.
• Annual billing commitment required for the listed rates; the 3-month pilot softens but doesn't remove that commitment.
• A 5% surcharge applies to card payments.
• Case-study results (containment rate, resolution rate, revenue share) are vendor-reported, without independent audit.
• The website was unreachable on 24 September 2026, so the pricing could not be re-confirmed that day.

Who is Certainly AI best for?

Certainly fits a D2C or ecommerce brand with real multi-channel support volume (web chat, Meta, email, maybe voice) that wants one AI agent handling all of it with model flexibility built in. The named case studies suggest it's used at both DTC scale (Quad Lock, Feastables) and large-enterprise scale (Ticketmaster, McDonald's).

It's a weaker fit for a small team just starting to explore AI support automation, since the €500/month entry price and annual billing are a real budget decision rather than a low-friction trial. It's also not built around a traditional help desk ticket queue. A team whose support already runs through Zendesk or Freshdesk and wants AI acting inside that system is solving a different problem than Certainly is built for.

Independent review evidence for Certainly is thin. Capterra lists it at 4.4 out of 5 from 13 reviews, which we re-read on September 24, 2026. Thirteen reviews is a sample worth reading in full rather than averaging, so treat the score as directional.

What are the alternatives to Certainly AI?

Certainly and Macha sit at different points in a support stack. Certainly is built to be the primary agent handling a brand's web, Meta, SMS, email, and voice conversations directly, often instead of routing everything through a help desk first. Macha runs as an agent layer on top of the help desk a team already has, so it fits a team that has standardized on Zendesk, Freshdesk, Gorgias, Front, HubSpot or Intercom and wants those existing tickets automated. It's done for you: the Macha team analyzes your past tickets, builds the knowledge base and the agent, and runs it in safe mode until the drafts are right, at about $0.40 a ticket, which includes setup and a dedicated success manager who handles your changes. For a closer comparison focused on ecommerce support tickets rather than a full multi-channel agent, Yuma AI sits nearer to Certainly's ecommerce customer base; it charges for conversations the AI fully resolves, a model that ties its revenue to resolutions rather than volume. If the multi-channel, sell-and-support shape is what you are after, Alhena AI is the other vendor competing for that brief.

How we researched this

The plans, channel coverage and feature detail come from Certainly's own pricing, product and documentation pages. The euro prices come from a capture of certainly.io/pricing taken on 15 September 2026; on 24 September 2026 the domain did not resolve, so we checked the Internet Archive instead, which holds a March 2026 copy of the pricing page with conversation caps but no prices, and a May 2026 copy of the homepage whose company data lists the 2017 founding year and Copenhagen address. We re-read the Capterra rating and Yuma's pricing page on 24 September 2026. We have not run Certainly on a live store ourselves.
