Where we look
One growth problem. Four places to investigate.
The symptom may appear in one channel while the cause sits somewhere else. We examine the full commercial journey before deciding where effort and budget should go.
Which opportunity or constraint matters most?
We define the commercial goal, trace the customer journey and identify the constraint most likely to change the growth trajectory.
Are you acquiring customers who create profit?
We build the offers, creative, campaigns and channel mix required to attract customers who create commercial value.
Where are valuable customers abandoning the journey?
We improve the path from first interaction to purchase across landing pages, ecommerce experiences, product pages and checkout.
Is your data producing better commercial decisions?
We connect measurement, lifecycle activity and practical automation to improve retention, decision quality and customer value.
Meta, Google Search and Shopping, and other relevant paid social or search channels
Shopify and other ecommerce platforms, landing pages, product pages, checkout and conversion testing
Email, SMS, lifecycle marketing, CRM and retention programmes
Analytics, tagging, dashboards, automation and martech integration
Depending on scope, Surge Catalyst executes directly, directs specialist delivery or works with your existing team.
The Surge Growth Diagnostic
Four lenses. One ranked growth opportunity.
We connect unit economics to the customer journey, identify where value is being lost or created and rank the opportunity most likely to change revenue and profit.
What you receive
- A commercial growth model connecting spend, margin and customer value
- A ranked opportunity map showing where value is being lost or created
- A 90-day intervention plan with priorities, owners and sequencing
- A measurement framework defining the commercial signal and next decision
The first intervention is large enough to produce a credible signal and focused enough to learn before committing more budget. Scope and timing are confirmed after the initial conversation.
How an engagement works
From growth question to measurable intervention.
Each engagement moves from a clear commercial objective to evidence, implementation and the next investment decision. Scope, responsibilities and measures are agreed before delivery begins.
Establish the objective and fit
We clarify what growth needs to achieve, the available evidence and the constraints around the decision.
Find the highest-value opportunity
We examine unit economics, acquisition, conversion, retention, customer behaviour, technology and data.
Create the smallest credible intervention
We implement the strategy, campaign, experience, lifecycle programme, automation or measurement change required to produce a clear commercial signal.
Scale, revise or stop with evidence
We interpret the result, improve what works and use the evidence to determine where the next investment should go.

Why Surge Catalyst
Senior growth judgement from diagnosis through delivery.
Surge Catalyst brings commercial strategy, acquisition, digital experience, lifecycle, data and technology into one growth decision. Each engagement is led by a senior strategist who stays accountable as the work is built, measured and improved.
Surge Catalyst was founded by Satheeshan Siva, a principal growth strategist with more than 15 years of experience across technology, digital platforms, ecommerce and commercial growth.
The four-lens diagnostic connects economics to the customer journey so effort goes to the lever most likely to change revenue and profit.
The senior strategist responsible for the engagement remains involved through implementation, measurement and the next decision.
We can move from offers, media and conversion into lifecycle, analytics, automation and platform integration when the constraint demands it.
Surge Catalyst can execute directly, direct specialist delivery or work with your team while keeping every contributor accountable to the same commercial outcome.
