Startum — Demo video

Most startups fail because they build something nobody wants. Startum is an AI co-founder that helps first-time founders find a real problem, prove people will pay for it, then build and launch the product. Ask one question, for example "Would physio clinics pay $50 a month for this?", and the Validation Autopilot takes over. It is a Muse Spark agent with ten tools. It reads the research, searches the web, checks competitor prices, narrates every step live and returns a Build / Pivot / Drop verdict. Every reason links to a source the agent actually read; the server drops any reason whose source never appeared in the run. A typical run takes 30–40 seconds and costs about $0.06 of Meta AI. From there, founders test with real people (voice interviews with speaker labels, waitlists, landing pages). Then Muse Image and SAM 3.1 design the brand, and Muse Spark designs every screen, links them into a clickable prototype and writes a runnable Next.js app. The Launch playbook and launch videos take the product to market. Startum works in English, French, Spanish and Arabic (right-to-left). Startum existed before the hackathon. During the hackathon we moved every AI feature onto Meta's models and built 13 new capabilities, including the Autopilot, voice interviews, brand visuals, page review, design → prototype → code, launch videos and Traditional → Innovative. HACKATHON.md in the repo separates hackathon work from earlier work; every hackathon commit is prefixed "Hackathon:", and the baseline is tagged pre-hackathon-baseline.
