Here is a running build guide and the prompts we used or would use to build the front end of the MVP for this Idea. “again this is a work in progress these are just our thoughts”
Our mock site, check it out: https://venture-growth-game.base44.app/
Budget: Under $1,000
You don't need a developer. You don't even need $10K. You need to prove the core idea and mechanics work. Kid chooses a business, faces real choices and challenges, feels immersive.
Build the entire MVP in Base44 or Replit. The simulation logic — weekly decisions, financial tracking, consequence outputs — is simple enough that a no-code AI builder handles it. The game at this stage is closer to an interactive web app than a full game engine. That's fine. You're not validating graphics. You're validating whether the decision loop is addictive.
Plug in Claude API or ChatGPT API as the AI advisor. Parent dashboard lives in the same build or a separate Softr page pulling from Airtable. Subscriptions through Stripe. Weekly parent email through Beehiiv.
Total cost: API usage + no-code tool + Stripe fees = under $1,000 until you grow the user base.
The Base44 / Replit Prompt to Build the Simulation
Paste this directly into Base44 or Replit AI:
"Build a web app called VentureAI. A kid picks a business type from these options: Lemonade Stand, Food Truck, Sneaker Brand, Pet Shop, Sports Card Store. After picking, they enter a weekly simulation loop. Each week they see: their current cash balance, their revenue from last week, their expenses from last week, and their profit or loss. They are then presented with one business decision card. Each decision card has a short scenario (2-3 sentences) and three choices. Each choice has a hidden outcome — positive, neutral, or negative — that affects next week's cash balance, revenue, and customer count. After they choose, show them the consequence in plain language and update their financials. Track a 'Town Growth Score' that increases with good decisions and decreases with bad ones. After 4 weeks, show a simple end-of-month summary: total revenue, total expenses, net profit, one concept they encountered (chosen from: profit margin, cash flow, supply and demand, reinvestment, pricing strategy). Include an AI advisor button on every decision screen. When clicked, it calls the Claude API with this system prompt: 'You are Nova, a friendly business advisor for kids aged 8-14. The kid just made or is about to make a business decision. Never give them the direct answer. Always respond with one question that helps them think it through. Keep responses under 3 sentences. Use simple language.' Store all game state in local storage. Build a simple parent dashboard page at /parent that shows: child's name, current week, total profit/loss, list of financial concepts encountered, and a summary of decisions made this week."
The Decision Library — Build These First
Before launch you need at least 20 decision cards per business type. Structure every card like this:
Scenario: 2–3 sentences describing a real business situation. Written at a 4th–6th grade reading level. No financial jargon.
Choice A: The smart move. Outcome: positive cash flow impact, +10 to Town Growth Score. Choice B: The neutral move. Outcome: flat financials, no score change. Choice C: The tempting but bad move. Outcome: negative cash flow, -10 to Town Growth Score.
Example card for Lemonade Stand:
"It's been a hot week and your lemonade is selling fast. Your supplier just raised the price of lemons by 25%. What do you do?"
A: Raise your prices by 25% to protect your margin. (Smart — margin preserved, slight customer drop) B: Keep prices the same and eat the cost this week. (Neutral — margin shrinks, customers stay) C: Buy a huge batch of lemons now to stock up before prices rise further. (Tempting — ties up all cash, risk of spoilage)
