The challenge
A fintech startup needed to build a multi-asset portfolio tracker covering stocks, ETFs, bonds, and crypto across 90+ global exchanges. Traditional data vendor negotiations take months and require enterprise contracts. The team of three engineers needed to ship an MVP in weeks, not quarters.
The solution
Using Eulerpool's free tier for development and Startup plan for production, the team built real-time portfolio valuation, historical performance charts, and dividend tracking. The TypeScript SDK integrated directly into their Next.js app. WebSocket streaming provided live price updates without polling.
The results
The app launched in 2 weeks with coverage across 90+ exchanges. Development cost during build: $0 (free tier). Production cost: $499/month for real-time data serving thousands of users. No vendor negotiations, no sales calls, no minimum commitments.
"Other data vendors wanted 6-month contracts and $50K minimums. Eulerpool let us ship in 2 weeks and scale on our own terms."
