Mathmo had a clear market fit, but couldn’t make the numbers work at scale because key fundamentals weren’t in place.
Three funnels (free student webinars, free parent webinars and paid challenges) confused prospects and cannibalised each other, and some free offers ended with nothing to buy.
No acquisition cost target linked to what a subscriber was worth, so there was no basis for spending more.
Nothing between sign-up and the live session, and no follow-up afterwards, so paid leads leaked before the pitch.
The webinar itself wasn’t built to close: no urgency, no webinar-only offer, and little handling of parents’ objections.
We worked in the order that limited our scaling potential: unit economics first, then offer and funnel, then creative and media.
1. Unit economics: make each customer worth more
Raised the subscription from £69 to £111 a month, timed to peak demand in the school calendar. Each increase raised what Mathmo could afford to pay for a customer.
Set a £3 cost-per-lead target from price and webinar conversion. Launch day came in at £1.80.
Eventually returned £1.66 in first-month revenue for every £1 invested, and an estimated £6.70 over each subscriber's lifetime.
2. Offer and funnel: one route to purchase
Cut to a single funnel: cold traffic → weekly parent webinar → subscription.
Repositioned the landing page around one outcome: jumping a whole GCSE grade boundary in 7 days.
Audited all 31 webinars Rob delivered live, feeding back weekly on structure, bonus stack, urgency and close.
Built email flows for pre-webinar reminders and follow-up, lifting conversion from 2.5% to 6.3%.
3. Creative and media: scale into demand
Led creative strategy, testing new hooks weekly on founder-led content and customer testimonial mashups.
Concentrated budget on peak-intent windows.

Founder, Mathmo
I was referred to Frontline thinking I simply needed help with ads. Sam's growth methodology looked at my whole business and tackled the key blockers before we spent more. Together, we refined my webinar USP, tested offer messaging over several weeks and killed the parallel programs I was building without clear direction. We also reworked the weekly webinar structure, presentation and pitch, strengthened our CRM by bringing in the right talent, led the ad creative strategy and finally scaled the ad spend. In our first year together, the business grew from £100K to £700K in annual revenue, and paid ads were the main driver of that 7× growth.
