Fintech Product Teams
Finance-correct embedded charts for your product without building a chart library from scratch.
The embedded chart problem for fintech startups
If you're building a fintech product — a portfolio tracker, a research terminal, a risk dashboard, a client portal — you need finance-correct charts in your UI. The standard approach: integrate a charting library (Highcharts, D3, Recharts) and build custom visualization components.
The reality: this takes weeks of engineering time per chart type. Candlestick charts alone require OHLC rendering, wick/body calculations, color logic, zoom behavior, crosshair tooltips, and volume subpanes. A vol surface requires 3D rendering. A yield curve requires interpolation math.
For a pre-Series B startup with limited engineering bandwidth, building a charting library is a poor use of resources.
Quadesto as your chart layer
Every Quadesto chart is embeddable via iframe. The embed inherits your data, updates when you refresh, and renders with finance-correct methodology.
The integration pattern:
1. Your backend pushes data to Quadesto via API (or your users upload directly).
2. Quadesto generates the visualization with correct methodology.
3. Your frontend embeds the chart via iframe, styled to match your product.
4. Users interact with the chart (hover, zoom, explore) without your team building any of that interaction logic.
What you get without building
Candlestick charts with volume — without implementing OHLC rendering.
Yield curves with proper interpolation — without implementing monotone convex.
Vol surfaces with SVI fitting — without implementing 3D rendering.
90+ computed indicators — without implementing any math.
Responsive, interactive charts — without implementing touch handling, zoom, or tooltips.
Cost comparison
Building a single finance-correct chart component from scratch: 2-4 weeks of senior frontend engineering (£8,000-16,000 at market rates).
Quadesto Pro with unlimited embeds: £149/month. You'd need to build 1.5 chart components per month for Quadesto NOT to be cheaper.
The math is clear for any team with fewer than 5 dedicated frontend engineers.
