From real-user evidence to confidence-ranked decisions

A 3-second delay can wipe out
30% of your revenue.

Most teams still cannot see what poor site performance is costing the business or which fixes matter first. Stroma turns that blind spot into evidence and a revenue-ranked path forward. Most teams still cannot see what poor performance costs or which fixes matter first. Stroma makes it measurable.

Every decision makes sense on its own. At scale, they compound into lost conversion: higher bounce rates, lower ad ROI, and users who leave before they convert. We diagnose the system, not just the symptoms. Each decision looks harmless alone. Together, they drag conversion down. We diagnose the system, not the symptom.

How It Works

From one URL to a commercial decision in three steps

You give us the site. We test it against the users you actually serve. You get a decision-ready Snapshot that shows whether deeper work is justified.

01 Submit

Share the site and market context

Share your production URL and tell us where your users are, so the test is calibrated to the market you actually serve.

02 Test

Run the site against customer reality

We test against real devices, real networks, and the conditions your customers actually experience, not office broadband or synthetic defaults.

03 Decide

Turn the gap into a decision

You get scores, revenue-at-risk ranges, and a clear recommendation on whether the evidence justifies deeper work.

Free. No call required. Delivered within 2–3 business days.

Inside The Snapshot Report

What lands in your hands

Every Snapshot is a web performance diagnostic structured to support a go or no-go decision, not just deliver a technical readout.

  • 01

    Bleed Index severity score

    A 0–100 score showing how much performance is costing you, with severity tier and urgent barrier summary.

  • 02

    Where revenue friction is showing up

    Drop-off patterns and likely friction sources: slow content, interaction delays, device mismatch, and third-party drag.

  • 03

    How your market context changes the picture

    Mobile versus desktop performance plus benchmark gaps calibrated to the region you serve.

  • 04

    Diagnostic evidence behind the gap

    The technical causes behind the slowdown: oversized scripts, third-party tags, render-blocking resources, and how they compound under real network conditions.

  • 05

    Commercial range and next-step recommendation

    Directional revenue-at-risk ranges with the assumptions behind them, plus a clear recommendation on whether deeper work is justified.

  • 06

    Evidence gate, not manufactured urgency

    If the numbers do not justify investment, the report says so. The point is decision clarity, not pressure.

Each layer answers a different decision. You commit more only when the previous layer proves the case, and every asset transfers to your team. Each layer answers a decision. You only go deeper when the evidence earns it.

Common questions

FAQ

Who is this for?

Anyone accountable for digital revenue, including CTOs, CMOs, product leaders, and founders, who ships web products to users on mobile or in markets with real infrastructure constraints. Engineering leaders get technical root causes. Marketing leaders get revenue impact tied to ad spend. Product leaders see which UX trade-offs are costing real performance.

How is this different from running Lighthouse ourselves?

Lighthouse gives you a lab score. The Snapshot shows what real-user performance is likely costing you in the market you actually serve.

It is designed to support a commercial decision, not just expose a technical issue. If you go deeper, the next layer replaces external benchmarks with your own measured data and a commercial model your team can challenge line by line.

Is the Snapshot really free? What's the catch?

Yes. The Snapshot is free because it is the first decision screen, not a teaser deck.

You get the report, the evidence summary, and the recommendation either way. If the numbers justify deeper work, we tell you what the next gate would build. If they do not, you still keep the Snapshot and the recommendation.

How accurate are the revenue estimates?

For the free Snapshot, they are directional ranges, not guarantees. We use published speed-to-conversion research, market calibration, and observable site evidence to size the gap conservatively.

If you go deeper, the next layer replaces external benchmarks with your own traffic, conversion data, and product economics. Every model is scenario-based, assumption-led, and explicit about correlation versus causation.

What happens after the Snapshot?

If the Snapshot shows meaningful revenue at risk, the next step is an evidence-gated system: measure what your customers actually experience, quantify what the gap is costing you, diagnose what is driving it, and decide what to fix first.

Each stage produces assets your team keeps. If the numbers do not justify deeper work, you still keep the Snapshot report, the evidence summary, and the recommendation.

What do we keep if we stop after the Snapshot or Gate 0?

If you stop after the free Snapshot, you keep the report, the evidence summary, and the recommendation.

If you proceed to Gate 0 and stop there, you keep the deployed measurement infrastructure, the Customer Infrastructure Profile, and the directional commercial assessment. Stroma builds capability that transfers to your team, not dependency on ours.

How is this different from a dev agency audit or a RUM tool?

A dev agency audit usually gives you generic recommendations. A RUM tool gives you ongoing symptom monitoring.

Stroma builds the layer between them: measurement infrastructure, a commercial model, diagnostic evidence, and a revenue-ranked decision system your team can operate independently. That is why the assets still matter after the engagement ends.

Do we need Stroma to implement fixes?

No. The goal is to hand your team or delivery partner a prioritised backlog, success criteria, and a decision playbook tied to measurement infrastructure.

Your internal team is often the right executor once the evidence is clear. Stroma can stay involved if useful, but the system is designed to be operated without us.

Eleven years at MultiChoice, building products like DStv Stream and MyDStv across design, development and engineering management for millions of users across Africa.

When your product reaches that many people on 3G and entry-level devices, you learn where performance actually breaks. It's rarely where dashboards point first. It shows up in compounded decisions that look fine in high-bandwidth offices but fail on real networks. That gap between what gets measured and what gets experienced is where I work.

That experience became the foundation for Stroma's approach: measure what's real, quantify what it costs, diagnose why, and prioritise fixes in waves that pay for themselves.

Eleven years at MultiChoice, building DStv Stream and MyDStv for millions of users across Africa, taught me where performance really breaks: on real networks and entry-level devices, not in office conditions.

That became Stroma's approach: measure what is real, quantify the cost, diagnose the cause, and prioritise fixes that pay for themselves.
