Challenge

Chatbase was founded in March 2023 as part of an early wave of startups building applications on top of large language models (LLMs). The company's platform enables customers – from fast-growing startups to large enterprises across industries such as tech, retail, and healthcare – to create AI agents that answer questions and resolve user issues.

The fully bootstrapped company runs a dual go-to-market motion – a high-volume self-serve channel where customers sign up, pay, and deploy agents without friction, alongside a sales-led track with personalised onboarding for enterprise accounts. "We need both ends to work seamlessly," said founder and CEO Yasser Elsaid. "A startup should be able to enter a payment method and go live quickly, and an enterprise should get the dedicated support and onboarding they expect."

Elsaid, who was Chatbase's only employee until June 2023, also wanted billing infrastructure that was easy to run, manage and integrate. The provider needed to support Chatbase's pricing model, which combines base plans with a set amount of monthly usage and options to pay for additional usage and purchase add-ons. Chatbase also aimed to mitigate the high fraud risk associated with its self-serve model, while maintaining the flexibility needed to attract more enterprise customers.

Solution

Elsaid decided to launch with Stripe based on its ease of use for both Chatbase's users and internal teams, as well as its ability to support the company as it grew.

Chatbase implemented Stripe Payments and Stripe's Optimized Checkout Suite, a set of prebuilt payment UIs and AI models, to deliver a modern payment experience designed to drive conversions. Using Stripe Checkout, a prebuilt payment form optimised for conversion, Chatbase helps customers easily complete payments using their preferred methods, including credit and debit cards, Apple Pay and Google Pay. Chatbase also integrated Link, a wallet built by Stripe that lets customers autofill payment details for faster checkout.

Chatbase chose Stripe Billing to manage and bill customers. With Billing, Chatbase could easily charge customers for both subscriptions and one-off purchases while retaining the flexibility to try out new pricing models, such as success-based pricing or per-seat pricing. Chatbase turned on Smart Retries to automatically retry failed subscription payments, using AI to determine the optimal retry time.

Chatbase prides itself on getting customers up and running on the platform quickly. The downside: "That introduces a lot of bad actors," said Elsaid, referring to card-testing attacks in which fraudulent actors use bots to rapidly test hundreds of stolen credit card numbers.

The company integrated Stripe Radar for Fraud Teams, Stripe's AI-powered fraud solution that uses data from more than $1.9 trillion in transactions to detect and block fraud while minimising false positives. Chatbase used Radar for Fraud Teams' no-code interface to implement custom rules that block fraud patterns known to be specific to its business.

Chatbase chose Stripe Revenue Recognition to automate complex GAAP revenue accounting processes. With Revenue Recognition, the team can use accurate data from both Stripe products and external sources to prepare audit-ready accounting statements with minimal time and effort.

To analyse and report on its data in greater depth, Chatbase implemented Stripe Sigma. Team members use Stripe Sigma to explore questions with natural language prompts, such as, "How much revenue are we making in that country?" or "How much revenue do we make from customers with this base plan and these add-ons?"

Results

Chatbase hits $10 million in ARR less than 3 years after launch

Chatbase landed its first paying customer 30 minutes after Elsaid published his first product demo. In March 2026, the company hit $10 million in ARR. "We have a lot of different customers around the world," said Elsaid. "Having a platform that handles different types of payments in different countries was the biggest benefit we got from Payments."

Without a dedicated billing team, Chatbase recovers $870,000 in revenue in 3 years

Chatbase has achieved its massive growth while remaining lean, with just 26 employees 3 years into its journey. Using Stripe products has allowed the company to avoid devoting precious engineering resources to payments or billing. "Billing is a very complex thing," said Elsaid. "Building this out on our own or using a legacy tool where the integration is not as easy would burn hours from our engineering team."

Efficiency hasn't come at the expense of revenue. Since launching in 2023, Chatbase has used Stripe Billing's revenue recovery features to recover $870,000 in revenue that might otherwise have been lost to payment failures. "Stripe makes sure we're not losing money we shouldn't be losing," said Elsaid.

Chatbase reduces fraud by nearly 40% with Radar for Fraud Teams

Chatbase has reduced fraudulent transactions by 37% with Radar for Fraud Teams. Designing custom rules tailored for the most common fraud schemes the company encounters has been particularly effective in preventing issues such as card-testing attacks and payments from accounts with suspicious email domains.

Chatbase accelerates accounting with Revenue Recognition

Chatbase uses the data and tools available in Revenue Recognition to speed up key but time-consuming accounting processes – saving up to three full days of work as a result. "Having one place where all the data and numbers are makes accounting much, much easier," said Elsaid. "You just download the CSV and then you run the numbers."

Chatbase partners with Stripe to move upmarket and capture enterprise demand

Chatbase initially found success serving SMBs. Now, the company is focused on expanding its enterprise customer base, while maintaining strong support for its SMB customers.

"Stripe is friendly and intuitive enough for the self-serve customers, but powerful enough to take to bigger companies and enterprises," said Elsaid.

For example, Chatbase anticipates using Billing to offer custom billing and pricing for larger companies. The team is also considering usage-based billing, which offers a no-code interface to simplify the management of usage-based pricing plans.
