What is Idea Builder?
Idea Builder
Great ideas are slow-cooked, like biryani, not instant-noodled.
Idea Builder is an AI-powered thinking space that helps you explore, challenge, and evolve an idea before you build it. Instead of asking one AI for a quick verdict, Idea Builder brings different perspectives to the table, from friends and mentors to customers, experts, researchers, investors, and potential cofounders.
Key features
- 🧠 Multiple AI perspectives — Talk to different personas, each with a distinct role, expertise, and way of thinking.
- 🔍 Deep investigation — Research users, problems, alternatives, markets, technology, business models, and risks.
- 💬 Natural conversations — Think out loud instead of filling out endless validation forms.
- 🧩 Connect the dots — See how conversations and evidence change your understanding of the idea.
- ⚡ Challenge your assumptions — Surface contradictions, unknowns, blind spots, and the questions that actually matter.
- 🗺️ Idea Observatory — A living view of how your idea evolves as you learn.
- 🎯 Next-action focused — End with clearer questions, experiments, and decisions rather than an arbitrary “idea score.”
Use it for:
Startup ideas, side projects, product concepts, business ideas, AI products, research ideas, or simply that idea you've been thinking about for months but haven't built yet.
What makes it different?
Most AI tools give you more answers. Idea Builder helps you figure out which questions are worth answering.
Explore. Challenge. Evolve. Build.

SaaS, getting four to five times EBITDA isn't [unreasonable]... I would recommend getting like two to three here at consumer.
Don't underwrite consumer-sub deals against SaaS comps — buyers price the gap
When raising debt or pitching acquirers for a CSS company, do not benchmark against B2B SaaS multiples. Consumer retention curves are structurally weaker (70% Y1 vs 90%), so debt and valuation math scale down proportionally. Crowley's M&A view: position the business honestly inside CSS norms instead of overreaching on SaaS comps and watching deals fall apart in diligence.
Hours 5 to 12 I started using Cursor to build out the core features. From there I spent hours 13 to 20 testing bugs and iterating. At hours 21 to 30 I thought I would spend a lot of time polishing the UI. Hours 31 to 40 edge cases. Hours 41 to 48 demo prep.
Plan the 48-hour MVP hour-by-hour, not as a vague "I will build this weekend"
Rather than a vague 48-hour ship goal, Hassam allocated specific hour blocks: 0-4 mapping the partner's SOPs, 5-12 core features in Cursor, 13-20 bug testing, 21-30 branded UI polish, 31-40 edge cases, 41-48 demo recording. The schedule forced shipping over polishing and made the demo deadline binding.
There's a play for whatever you're stuck on.
