About
Prostir is a no-code platform for launching custom AI apps without building the backend yourself.
Users upload their knowledge, write plain-English rules, connect tools such as Stripe, HubSpot, Notion, Slack, or custom APIs, then launch one AI app that can work inside ChatGPT, Claude, Cursor, a website, or a web app. Prostir handles the technical layer behind the product: knowledge ingestion, MCP endpoints, tool access, authentication, customer accounts, usage limits, Stripe-backed payments, and deployment.
The product is built for experts, creators, consultants, SaaS teams, course owners, and businesses that have useful knowledge or repeatable workflows and want to turn them into a working AI product. A consultant can package playbooks into a paid AI expert. A course creator can launch a tutor that answers from approved material. A SaaS company can ship a customer support or onboarding assistant trained on its own documentation. An internal team can create a private helper for recurring questions and tasks.
Prostir solves the gap between “this works in ChatGPT” and “customers can actually use and pay for it.” Custom GPTs are limited to one platform and usually leave creators without payments, customer ownership, usage controls, or proper deployment options. Building a custom AI backend from scratch means developers, auth, hosting, tools, APIs, MCP, payments, dashboards, and months of work. Prostir packages that infrastructure into one product flow.
The goal is simple: help people turn knowledge, instructions, and tools into live AI apps faster, with clear control over who can use them, what they can access, how they behave, and how they are monetized.

Sometimes people misinterpret that as 'oh I have to do all of these things, I have to tick all of these boxes in order to be successful.' No, absolutely not. You have to play to your strengths and to your company stage and your priorities. If you try to overreach and do everything, you're going to do it all really badly.
The Mobile Growth Stack is a menu, not a checklist
Andy's framework encapsulates everything that could form part of a mobile growth strategy — but its purpose is to help teams pick, not pile on. Stage-appropriate focus beats comprehensive coverage; early stages reward big swings on PMF, not sophisticated experimentation infrastructure.

App Category Waves: Fitness Then Meditation Then Creator Tools — Ride the Next Wave Early
Thomas Petit maps health/productivity app evolution as wave patterns: general fitness came first, then meditation opened the adjacent space (enabling Reflectly after Headspace/Calm), now creator tools — professional TikTok/Reels editing — are the next wave. CapCut is the breakout leader dragging 20 medium-sized apps with it. Identifying the wave early, before the category is saturated, is the highest-leverage moment to launch.
There's a play for whatever you're stuck on.
