How Subthirtyfive Turned a Niche Wealth Manager Community into a Thriving Digital Platform

The Challenge 

Subthirtyfive — an exclusive club for up-and-coming wealth managers, founded in partnership with Baillie Gifford, Janus Henderson, and Winterflood — needed to evolve how it engaged members.
Pre-pandemic, events were in-person breakfasts and evening sessions. But with their audience largely working from home, the job to be done was:
“Take a live, physical community and transform it into a digital-first platform without losing impact or credibility.”

What They Needed 

• A way to replicate structured, CPD-accredited events online.
• A custom digital platform with interactive features and on-demand educational content.
• End-to-end support with event production, promotion, and analytics to satisfy sponsors and keep growing the community.

Our Approach

We helped Subthirtyfive seamlessly transition to digital:

• Video production for live events in London and Edinburgh (2018–2019), capturing fund manager insights.
• Full digital transformation during the pandemic, creating an online hub with on-demand videos, blogs, and CPD-accredited resources.
• Virtual event production: hosted by Winterflood, with leading managers from Baillie Gifford and Janus Henderson. Branded throughout to Subthirtyfive guidelines.
• Audience engagement: managed registrations, ran targeted email campaigns, conducted speaker tech tests, and facilitated live Q&A.
• Post-event value: produced on-demand versions for the site and delivered analytics reports to sponsors.

The Results

• The first online event was a resounding success:
  • Over two-thirds of registrants attended live.
  • Positive feedback from sponsors, speakers, and attendees, including Annabel Brodie-Smith (AIC).
• Subthirtyfive thrived online, expanding reach and sponsor interest.
• Ongoing partnership with Bombora to deliver future virtual and hybrid events.

The Takeaway

We didn’t just help Subthirtyfive run webinars — we helped them pivot their entire model from live-only to a scalable digital-first platform that keeps members learning, connected, and accredited.
