For our first eight months, we required a credit card at signup. Standard SaaS practice. The reasoning is well-known: a credit card requirement signals intent, filters out tire-kickers, simplifies the upgrade flow. We believed it. We were wrong.
The argument for credit cards
The logic is seductive. Onboarding is expensive — it consumes infrastructure, support time, setup effort. People who aren't serious enough to enter a credit card aren't worth that cost. And once you have a card on file, converting to paid is frictionless: one click, not a procurement cycle.
This logic is correct in some markets. It's wrong in ours.
What the data said
In month eight, we ran a retrospective on signup cohorts. The question was simple: what's the best predictor of whether a new account becomes a paying customer?
The answer was not whether they'd entered a credit card. It was whether they'd completed their first setup — whether they'd connected AIVA to a real data source and had a real conversation with it.
Accounts that completed first configuration converted at 68%. Accounts that didn't: 4%. The credit card was completely uncorrelated with conversion.
The implication: the bottleneck wasn't intent. It was activation. People who signed up with a card weren't more likely to convert than people who'd sign up without one. They were equally likely to activate — or not — based on factors that had nothing to do with payment information.
Meanwhile, the card requirement was reducing signup volume. We ran a three-week A/B test removing it. Signups increased 340%.
The maths
After removing the credit card requirement:
- New signups: +340%
- Signup-to-paid conversion rate: 28% (down from 31%)
- Net paying customers acquired: significantly up
The conversion rate dropped slightly — some of those new signups were genuinely casual. But the net paying customers acquired per month increased substantially, because 340% more people were entering the funnel and 72% of them still converted.
More importantly: the customers who converted without a card on file were just as likely to stay paying as those who'd had one. Churn rates were identical.
We were solving for the wrong problem. The friction we needed to remove wasn't in the payment flow — it was in the activation flow.
What we built instead
Removing the card requirement was easy. What came next was harder.
The insight was that activation — getting a customer to their first real AIVA conversation — was the actual conversion moment. So we rebuilt onboarding around getting there as fast as possible. Pre-built setup templates. A wizard that connects a data source in four steps. An email sequence that pings you if you haven't completed configuration after 48 hours.
First-configuration rate went from 34% to 61% in six months. That 27-point improvement in activation did more for our growth than any other change we've made.
Today every new AIVA account starts with ₹500 of free credit — enough to run real conversations on real traffic before you decide whether to recharge. No card required.
The lesson: credit card requirements are a solution to a problem (intent filtering) that isn't the problem most products actually have. The problem is activation. Optimise activation, not intent signals.
