The Playbook: How to Build a Great App in 2025

With the rebuild behind them, Eyal and Yali share the structured playbook they wish they'd had from day one. Step one is knowing exactly who you're building for and what their pain points are. Step two is becoming data-obsessed — not just looking at top-line numbers but understanding what the conversion funnel is telling you at every stage. [1] — Eyal "Step 1: know exactly who you're building for. Step 2: worship your data. Step 3: obsess over in-app analytics to find drop-off points. Step…" 06:54 Step three, Yali adds, is obsessing over in-app analytics: tracking feature clicks to identify your most compelling value proposition, and watching onboarding screens to see exactly where users drop off. Step four is scaling through influencer marketing — but only after the product is ready to convert. The evidence is vivid: their 70th influencer video hit 600,000 views and pushed ARR from $8,000 to $38,000 in three days.

One viral video: $8K to $38K ARR in 3 days
A single viral influencer video with 600,000 views drove PropGPT's ARR from approximately $8K to $38K in about 3 days.
One Viral Video Took ARR From $8K to $38K in 3 Days
Their 70th influencer video hit 600,000 views and single-handedly pushed PropGPT's ARR from $8,000 to $38,000 in three days. Influencer marketing has a lottery-like upside — but only if the product can hold the users it acquires.
PropGPT's Tech Stack and Cost Structure
PropGPT runs on React Native with TypeScript and Python for ML, Neon for the database, RevenueCat and Superwall for monetization. LLM costs are $20/month, data APIs $100/month, and after $10K in monthly marketing spend, margins sit at roughly 50%.

$10K/month marketing spend
PropGPT spends approximately $10,000 per month on influencer marketing.
Final Advice: Co-Founders, Demand, and Conviction
Get a co-founder who has your back. Be scientifically honest about whether your idea has real demand. Once you convince yourself, it becomes an order of magnitude easier to convince investors and team members to join you.
