# How ReplyDaddy Went From a Reddit Script to a SaaS Business With Dodo Payments > Before ReplyDaddy was a SaaS, it was a Reddit script and two customers willing to pay for it. - **Company**: ReplyDaddy - **Industry**: AI - **Payment provider**: Dodo Payments (Merchant of Record) - **Published**: 2026-07-07 - **URL**: https://dodopayments.com/case-studies/replydaddy ## Key Metrics - **127 signups** -- Generated in one week from the original script - **3 countries** -- Reached after launching with Dodo Payments - **2 days** -- To integrate using AI and documentation --- ## The Company **ReplyDaddy: AI-powered Reddit marketing built for founders and agencies** ReplyDaddy started as an internal tool. Neel was building another startup, TeacherOp, and needed a way to market it on Reddit. Existing tools weren't solving the problem. Many relied on automated posting, leading to account bans and low-quality responses that were easy to spot as AI-generated. Instead of continuing to search for a solution, Neel built his own. What began as a simple CLI script helped generate 127 signups in a single week. After sharing the results publicly on Twitter, two people reached out asking to buy the script. At that point, ReplyDaddy wasn't even a product. It was just proof that a problem existed. Today, ReplyDaddy helps agencies, SMBs, and indie founders discover relevant Reddit conversations and generate contextual AI-assisted replies without risking account bans. Around 60% of customers are agencies running Reddit marketing for clients, with the remainder split between businesses and independent founders. ## The Challenge ### A founder needed to validate demand before building a business Neel wasn't looking for a complex payment integration. He needed a way to answer a simple question: would people actually pay? When two customers offered to purchase the original Reddit script, speed mattered. There was no SaaS product, no billing system, and no time to build one. The payment experience needed to be simple, trusted, and available immediately. At the same time, Neel was building with AI rather than traditional engineering resources. Any future payment infrastructure would need documentation good enough to work seamlessly with tools like Claude. He had previously used LemonSqueezy but found the experience unintuitive and slower than expected. For a solo founder focused on shipping quickly, payments couldn't become another project. > "I went to Dodo, I created my account for ReplyDaddy, it got approved in a day or two. Then I created two payment links for $199 and shared them. They made the payment and I sent them the source code via email. That's when I was sure that monetisation was possible for this product." > > -- Neel, Founder, ReplyDaddy ## The Solution ### From payment link to full SaaS infrastructure Dodo's first role in the ReplyDaddy story wasn't powering subscriptions. It was helping validate the business. After creating a Dodo account and getting approved, Neel generated two payment links and shared them directly with buyers. Within hours, the payments were completed and the source code was delivered. No integration was required. Once ReplyDaddy evolved into a SaaS product, Dodo became the long-term payments infrastructure. As a Merchant of Record, Dodo handles: - Global payment acceptance - Recurring subscription billing - Tax collection and remittance - Payment links for custom purchases - Developer-friendly documentation - Fast onboarding and approvals The transition from validation to production happened on the same platform. > "I barely open the dashboard these days. It is not required. Unless I have to create a custom payment link, I don't open it. That's what I like--it just works." > > -- Neel, Founder, ReplyDaddy ## The Implementation ### Built in two days using AI and documentation When ReplyDaddy became a SaaS, Neel completed the integration in two days. Rather than writing everything manually, he used Claude alongside Dodo's documentation to generate much of the implementation. The process was straightforward enough that payments, subscriptions, and billing were live within 48 hours. What stood out wasn't just the speed of setup, it was the lack of maintenance afterwards. Webhooks worked. Subscriptions renewed. Payments processed successfully. For a solo founder running every part of the business, that reliability mattered more than features. > "If you go to Twitter and someone asks for a payment gateway suggestion, maximum replies will be Dodo Payments. Especially with Stripe not being available in India, it's very helpful for founders." > > -- Neel, Founder, ReplyDaddy ## The Results ### From a payment link to a growing SaaS business Dodo Payments didn't just help ReplyDaddy collect payments. It helped prove the business should exist. ### Validation before a single line of product code The first two customers paid $199 each through Dodo payment links before ReplyDaddy existed as a SaaS. Those transactions provided the confidence to invest time and effort into building the full product. Instead of guessing whether people would pay, Neel had proof. ### 125+ signups from the original script Before becoming a product, the original Reddit script generated 127 signups in a single week. The combination of user interest and successful payments validated both demand and willingness to pay. ### Built and maintained by one person The Dodo integration was completed in two days and has required minimal attention since. Payments run in the background while Neel focuses on product development, customer conversations, and growth. ### Global payments without compliance overhead ReplyDaddy serves customers across multiple countries, including agencies and businesses using Reddit as a marketing channel. With Dodo operating as Merchant of Record, tax collection and remittance are handled automatically, removing a major operational burden for a solo founder. > "Dodo will be the primary payment gateway for ReplyDaddy and for any other platform I launch as well. The onboarding was really fast, the setup is quick, the documentation is really good, and the team is very responsive." > > -- Neel, Founder, ReplyDaddy For ReplyDaddy, Dodo Payments wasn't just part of the product journey. It was the first proof that the journey was worth taking. --- ## About Dodo Payments Dodo Payments is the billing and payments platform for AI-first companies.
