Competitive analysis emails
Local competitors on an interactive map with rating comparisons and competitive gaps highlighted in real-time.

6× demo bookings. Zero HubSpot API calls.
Owner.com’s outbound team needed personalized images at HubSpot’s scale — thousands of prospects, each with a unique chart pulled from their own market data. HubSpot couldn’t reach external APIs at send time. So we built a three-layer rendering engine that pre-bakes the personalization upstream, lets HubSpot send a static URL, and ships an image that looks bespoke to every recipient.

Increase in demo bookings
Dynamic personalization transformed Owner.com's outbound performance, delivering a 6× increase in demo bookings through hyper-personalized, data-driven email campaigns.
The challenge
HubSpot can't call external APIs.
Owner.com is the all-in-one platform for independent restaurants — online ordering, websites, marketing, loyalty, and a direct channel that takes the third-party commission out of takeout. Their outbound team needed to reach thousands of restaurant operators with email that proved Owner already understood their market, their menu, and their delivery competition before the first reply.
Traditional email personalization stops at merge tags. You can insert {{first_name}}, but you can't fetch live data, render competitor comparisons, or show real-time business scores.
Owner.com needed to send hyper-personalized emails showing:
- Local competitor analysis with interactive maps
- Business performance scorecards with live metrics
- Website preview screenshots with brand analysis
- Live reputation metrics and review scores
All without HubSpot making a single API call.
System architecture
The three-layer solution.
A three-layer architecture that turns static email templates into dynamic, data-driven visual experiences. Each layer owns one job and hands off cleanly to the next.

Layer 2 · Rendering platform
Fetch & merge data, server-side HTML rendering, image rasterization, public CDN URLs.
3
Layer 3 · OpenGraphImage.com
Web crop optimization, email-safe formatting, global CDN delivery, device scaling.

What the team said
In their words.
We needed personalized email at a scale HubSpot couldn’t touch. BRCG built the rendering engine that made it possible — every prospect got a unique image generated from their own market data. Demos 6×’d in the first quarter.
