🔧 Workflow

Take on new requirements every evening, first reviewing the business workflow with the client via voice or text and organizing it into a requirements document. The next day, use natural language to describe the client's requirements on Vibe Coding platforms like Base44, where AI automatically generates applications containing databases, user authentication, and business logic. Humans act as referees to conduct item-by-item acceptance testing: running through logins, permission isolation, and core CRUD (Create, Read, Update, Delete) operations, and having AI correct discrepancies. The input consists of the client's requirement interview records and business sample data, and the output is a production-ready internal management tool, supplemented by monthly fixed hosting and maintenance. After template reuse, a project from requirements to delivery is compressed to 1 to 3 days, while hosting multiple long-term clients yields only monthly fees.

🛠 Setup Requirements

Requires the ability to sort out business workflows and write clear requirement descriptions. There is no need to know how to code, but basic concepts such as database table structures, role permissions, and single sign-on (SSO) must be understood. For tools, subscribe to Base44 or similar platform plans, use Lark or Notion to manage requirement documents and acceptance checklists, and use WeChat or WhatsApp to communicate with clients. In the initial stage, help friends or nearby small merchants for free or at a low price to build one or two cases, accumulating reputation and acceptance checklist templates; you can start taking orders within 2 to 4 weeks. It is recommended to organize the interface screenshots and business workflows of the first successful case into a portfolio page, which will significantly increase the conversion rate for subsequent customer acquisition.

💰 Revenue

① SME internal tool custom building (main revenue): Business owners pay service fees per project, ranging from 3,000 to 10,000 RMB per project. When steadily serving 8 to 15 clients, the combined monthly income from new projects and inventory hosting is about 10,000 to 30,000 RMB (proportions between the two are not explicitly split according to the case study source, unindependently verified; observed up to 2026); ② Inventory hosting subscriptions: Delivered clients pay a monthly maintenance fee of 500 to 2,000 RMB, turning one-off project payments into recurring cash flow (public figures for active client count and volume in this segment are unavailable, and weight is not broken down); ③ B-end major orders and deep customization: Services for process-complex enterprises charged via project service fees. According to the source, top-tier builders targeting B-end major orders can earn more, though quotes and volume are undisclosed, and their revenue share is also blank; ④ Opportunity item—Platform ecosystem delivery acceleration: Base44 was acquired by Wix in June 2025 for an initial consideration of approximately $80 million, with about $25 million reserved for retention bonuses (according to company announcements). The platform continues to increase investment, allowing builders to reuse templates to amplify delivery, though revenue from this channel currently has no standardized metric.

💸 Cost

Platform subscription is about 200 to 500 RMB per month, plus minor domain, deployment, and communication tool costs, totaling under 500 RMB per month—far lower than the human resource overhead of traditional development.

⏱ Time Investment

2 to 4 hours per day handling requirements, acceptance testing, and revisions, with catch-up work on weekends during peak project periods. After template reuse, an individual can manage over 3 projects in progress simultaneously.

🚀 Getting Started

Step one: Practice using a fictional requirement on a Base44-class platform, such as a reservation plus inventory system for a small restaurant, building a demo that can log in and modify data. Step two: Find a small business owner friend nearby and build an inventory or booking tool for them for free in exchange for detailed usage feedback and a testimonial. Step three: Start charging for the third project, pricing based on business value, and bundle monthly hosting and maintenance upon delivery, turning one-off revenue into recurring annual compound revenue.

🔑 Keys to Success

✅ Humans must act as referees to inspect AI-generated application logic item by item; errors in database permissions and login isolation will directly ruin reputation.
✅ Template compounding is core: accumulate past inventory, booking, and CRM solutions into a base foundation, and subsequent projects can be delivered with minor tweaks, increasing gross margin with volume.
✅ Pricing should be based on business value rather than working hours, avoiding the race-to-the-bottom price war of per-head or per-day outsourcing.
✅ Sign clear maintenance scope and change-charge clauses upon delivery, controlling infinite feature requests within the renewal contract. Hosting fees are the source of stable cash flow.

⚠️ 风险

⚠️ Platform price hikes or changes in functional strategy will directly raise delivery costs and compress gross margins.
⚠️ Loss of control over client expectations, treating Vibe Coding as an infinitely free request-revision loop, leading to project failure and losses.
⚠️ If strict acceptance testing is neglected, security vulnerabilities in AI-generated applications could lead to client business data leaks and legal disputes.
⚠️ As similar platforms and competing builders flood in, the pure-order-taking model may be eroded by price wars, requiring deep industry cultivation to build a moat.

📌 Real Cases

📌 Base44 was founded by Israeli solo entrepreneur Maor Shlomo. Within about 6 months of launch, it attracted over 10,000 enterprises and thousands of paying users, and was acquired by Wix in June 2025 for $80 million in cash plus performance-based earn-outs. He stated that his monthly profit before acquisition was about $189,000.
📌 According to public post-mortems, Base44 reached an ARR of about $1 million 3 weeks after launch, $1.5 million at 4 weeks, and $3.5 million ARR in 6 months before being acquired by Wix. The process involved zero external financing, and the final transaction included a $25 million team retention bonus.
📌 Post-acquisition, Base44 launched its proprietary model Base 1 as an independent business under Wix and expanded into multilingual markets such as Japanese, indicating that the platform continues to increase investment, and the ecosystem window for providing custom building services based on it remains open throughout 2026.
