Free trial is free exploit ????

Sorry for my english, it's not my first language. For context, i'm now spending a lot of money in order to understand if i should provide or not a free trial to a user, because of abuses i had last few days. Ok so just a little bit of context, I have a good traction on all my 4 applications (more than correct MRR regarding the current state of SaaS, and many users that connects everyday), but honestly i am at lost regarding free trial.

AI 分析

痛点:SaaS 免费试用被批量滥用,尤其来自特定地区,导致获客成本被恶意消耗,创始人被迫关闭试用或投入额外成本做限制。

目标用户:提供免费试用的中小型 SaaS/独立开发者,尤其是按用量计费、AI API、云服务类产品。

证据:i'm now spending a lot of money in order to understand if i should provide or not a free trial to a user, because of abuses i had last few days... we had so many users that tried to exploit our free trial from Asia that we had to just shut it down. ... giving 5$ usage to new users (we have approx 100-150 new users per day) is harsh

变现:按用量或按月订阅的反滥用 API/SaaS,提供风险评分、设备指纹、邮箱/手机/信用卡验证、IP 情报和试用额度控制;也可做 Stripe App 或 Shopify App 插件,按拦截量或 MAU 收费。

MVP:2 周内做一个轻量 API + JS SDK:注册时检查一次性邮箱、代理/VPN IP、设备指纹、同一支付卡/邮箱复用、速率限制,并给出风险分;支持 Stripe 卡指纹校验和人工白名单,先服务 5-10 个 SaaS 创始人。

竞品:Stripe Radar、Fingerprint、Sift、SEON、IPQualityScore、Castle、Arkose Labs

摘要:一位 SaaS 创始人抱怨免费试用被严重滥用,旗下 3 个产品曾因亚洲地区滥用而关闭试用,当前项目每天 100-150 个新用户、每人送 5 美元额度,成本压力明显。他正在花不少钱研究是否继续提供免费试用,说明反试用滥用有真实需求和付费可能,但该领域已有 Stripe Radar、Fingerprint、SEON 等成熟竞品,独立开发者需从轻量、垂直或低价角度切入。
