The problem: live isn't the same as implemented

Qonto offers an integrated finance platform: business banking, expense management, invoicing, insurance, premium cards, account aggregation. Every module is built. Every module is shipped. None of it matters if customers go live on basic banking and never configure the rest.

"We had built powerful capabilities across every module, but customers weren't completing the second half of implementation," says Maxime Champoux, Head of Product. "They were live on basic banking. That's not implementation done. That's implementation half-done."

This is the problem every implementation team eventually inherits. The customer is technically live. Their account is configured for the core use case. They're using something. But they're not using the parts of the product that earn the renewal or unlock expansion. The longer they stay shallow, the more vulnerable the account becomes to a competitor pitching a single feature done better.

For Qonto specifically, the gap was visible in the data:

• Insurance products and premium card upgrades had near-zero organic discovery

• Multi-step workflows like account aggregation sat at 8% activation

• Customers stuck to basic banking while competitors pitched them specialized alternatives

Qonto didn't need to onboard these customers. They were already on. They needed to keep them moving, account by account, into the parts of the platform they hadn't found yet. That's post-sales implementation, at SMB volume the team could never reach by hand.

Impact

• 375,000 customers guided through a redesigned interface without disruption

• 2x increase in activation on multi-step workflows

• 10,000+ customers moved into insurance and card upgrade flows in 2 months

• 40% faster time-to-first-value on new features

• 3-10x higher engagement than traditional product tours

The solution: an agent that watches each account and surfaces what they're missing

Qonto deployed Tandem with a JavaScript snippet. Once live, the agent sits inside the product and watches what each customer is doing. When a customer is in a context where a feature they don't yet use would help them, Tandem surfaces it. Not as a popup. Not as a tour. As an offer to walk them through it, right there, in the product.

"It addresses our navigation challenges and helps customers extract more value from Qonto," says Champoux. "As a result, we see an increase in activation and a decrease in support tickets across the board."

The shift isn't from no guidance to some guidance. Qonto had documentation, tooltips, and product tours. The shift is from static guidance that depends on the customer finding it to contextual implementation that arrives when the customer is most likely to act on it.

What Tandem actually does

Configures the modules customers never opened on their own

Before Tandem, Qonto had no in-product way to move customers into insurance or card upgrade configuration. These high-margin modules sat undiscovered.

Tandem watches for the right context. When a customer is viewing transaction limits, Tandem can surface a card upgrade. When they're managing expenses, an insurance product. The agent doesn't just suggest the upgrade. It walks them through the entire configuration.

Result: in two months, more than 10,000 customers completed implementation on insurance and premium card modules that previously generated zero in-product activity.

Unblocks multi-step configuration

Qonto's most powerful features (account aggregation, team permissions, advanced reporting) take multiple steps to configure. Customers used to abandon halfway and never come back.

Tandem walks them through the steps with context-aware guidance. When a customer hits a decision point, the agent explains what's actually happening and why. Account aggregation alone went from 8% to 16% activation. Customers who complete these flows stick around longer and use more of the platform.

Carries customers through product changes without losing them

When Qonto rolled out a redesigned transactions interface (v2), they needed to bring a million existing customers through it without losing them. The old way to handle this is documentation, in-app announcements, and support tickets when customers get lost.

Tandem walked 375,000 customers through the new interface contextually. Each one got the introduction at the moment they encountered the change, not in an email they would have ignored. Adoption of new features hit 3x in the first month compared to organic discovery.

What changed

The Qonto team considered building this themselves. They have engineers. They have AI capability. They considered the path.

The math didn't work. Six months to build. Two full-time engineers to maintain. Specialized expertise in prompt engineering, intent detection, and conversation design. Plus the ongoing work of keeping the agent in sync with a UI that changes constantly.

"The decision was clear," says Champoux. "Tandem brought capabilities we couldn't replicate quickly. The agent understands context, adapts to customer behavior, and self-heals when our UI changes."

The deeper change was cultural. Qonto's product team became Tandem's biggest internal champion. More than 60 employees actively share ideas for new Tandem flows in their internal Slack. Account receivable onboarding, registration funnel configuration, complex business workflows. Every team with a post-go-live implementation problem found a use for the agent.

What's next

Qonto is expanding Tandem across the platform with a single goal: make sure every module reaches best-in-class adoption.

Current initiatives include:

• Account receivable onboarding flows

• Registration funnel configuration

• Complex business workflows customers used to abandon

• Behavioral signals to identify accounts at risk before renewal

The pattern is consistent. Wherever a post-sales implementation gap exists between what Qonto built and what customers configure, Tandem closes it.

The bottom line

Implementation doesn't end when the customer is live. It ends when the customer is actively using everything they signed up for. Qonto's team treats that distinction as the foundation of their platform's growth, and Tandem is how they extend implementation to a million customers without scaling the team behind it.

"Every customer who discovers our full capabilities through Tandem is a customer who won't need to look elsewhere. In a market where competitors try to unbundle financial services, we're using AI to keep customers configured on the integrated platform that delivers more value." — Maxime Champoux, Head of Product, Qonto
