What’s actually happening right now

✗
Your product works. Users like it. But activation hasn’t moved in months — and nobody can tell you which design changes would actually move it.

You’ve shipped redesigns. Some felt right. But without friction data tied to revenue, you’re optimising by instinct. The team has strong opinions. What’s missing is a system that turns those opinions into testable hypotheses with measurable outcomes.

✗
Your design team is talented. They ship good work. But design decisions still come down to opinions — and there’s no framework to settle them with data.

The team knows good design. But without friction data and conversion metrics attached to each decision, the loudest voice wins by default. Your best designers want to be measured on impact, not aesthetics. They just don’t have the system to do it yet.

✗
Your product looks good. Users say it’s “well-designed.” But you can’t draw a line from design decisions to revenue metrics — and the board wants that line.

Design is doing its job aesthetically. But the gap between “looks good” and “converts well” is where revenue lives. The onboarding flow, the pricing page, the upgrade path — each one has friction you haven’t quantified yet. That’s the ceiling.

Six weeks from now

✓  Data-backed

Every design decision has friction data behind it. You stop redesigning based on HiPPO opinions. You walk into every design review with session recordings, funnel drop-off points, and a ranked priority list. Your design team stops losing 3 weeks to “let’s try both.”

✓  Converting

Your activation rate is climbing — measurably, sprint over sprint. Your pricing page converts better because it was redesigned around user behaviour, not opinions. Every flow change has a before-and-after metric. Design is a revenue lever you can actually pull.

✓  Revenue-driver

Your board sees design impact in revenue metrics — activation up, churn down, expansion up — not just “prettier UI.” Your design budget is an investment with measurable ROI, not an expense line. Top design talent wants to work where design moves numbers.

What changes when design decisions are data-backed

Now With ProductQuant

Design decisions informed by experience and intuition Every design change backed by session data + A/B tests
Onboarding completion steady — friction points not yet quantified Friction quantified and removed — completion rate climbing
Pricing page conversion unmeasured against category benchmarks Pricing page redesigned around user behaviour data
Design impact evaluated by aesthetics, not revenue metrics Design decisions defended with conversion data

How It Works

The D.R.I.V.E. framework. Design that ships results in 4-6 weeks.

Three phases. Every design decision backed by user data. Every pixel tied to a conversion metric. No redesigns based on gut feeling.

D
Phase 1

Diagnose

Week 1-2. Friction analysis across your entire product. We find exactly where users drop off — and why.

  • Full-funnel friction audit (signup to activation)
  • Heatmap + session recording analysis
  • Drop-off quantification by flow step
  • Design Impact Assessment (see below)
R
Phase 1

Research

Week 1-2 (parallel). User session deep-dives, heatmap pattern analysis, and behavioural segmentation.

  • User session recordings review (200+ sessions)
  • Click/scroll heatmap analysis per key page
  • Behavioural cohort segmentation
  • Competitive UX benchmarking
I
Phase 2

Iterate

Week 3-4. Rapid design sprints targeting the highest-impact friction points. Prototype, test, refine.

  • Design sprint (1 high-impact flow per sprint)
  • High-fidelity prototypes in Figma
  • User testing with 5-8 target users
  • Iteration based on test results
V
Phase 2

Validate

Week 4-5. A/B testing the redesigned flows against current. No opinions — only statistically significant results.

  • A/B test setup + hypothesis documentation
  • Statistical significance monitoring
  • Conversion lift measurement per variant
  • Winner deployment + documentation
E
Phase 3

Embed

Week 5-6. Design system handoff so your team can maintain and extend everything we built — without us.

  • Component library (Figma + code)
  • Design system documentation
  • Pattern library with usage guidelines
  • Team training + handoff session

Before we redesign anything, we measure everything.

The Design Impact Assessment runs in week 1. It tells you exactly where your product is bleeding users — and quantifies the revenue cost of each friction point.

1

Conversion Funnels

Where are users dropping out of your signup, onboarding, and upgrade flows?

  • Step-by-step funnel drop-off rates
  • Revenue impact per drop-off point
  • Benchmark comparison by product type
2

Friction Points

Which UI elements are confusing, blocking, or frustrating users?

  • Rage click + dead click analysis
  • Form abandonment audit
  • Error state frequency mapping
3

Design Debt

How much inconsistency exists across your product's UI patterns?

  • Component inconsistency inventory
  • Accessibility compliance gaps
  • Technical debt vs. design debt triage
4

Activation Gaps

What's the gap between signup and "aha moment" — and what's causing it?

  • Time-to-value measurement
  • Onboarding completion rate by step
  • Feature discovery path analysis
5

Device Parity

Is your mobile experience bleeding conversions your desktop captures?

  • Mobile vs. desktop conversion gap
  • Responsive breakpoint audit
  • Touch target + interaction review

Why this matters: Most redesigns fail because they start with aesthetics, not evidence. The Design Impact Assessment gives you a prioritised list of exactly what to fix, ranked by revenue impact. No guessing. No "let's just refresh the whole thing."

Conversion Lift Guarantee

If your redesigned flow doesn't show measurable conversion improvement within 60 days of deployment, we iterate free until it does. We measure success in metrics, not mockups.

Your design is polished. The next step is making it measurably effective.

Your product looks good. Modern. Professional. Your team ships consistent UI. Your Figma files are organised. Nobody complains about the design.

The opportunity is what happens when you connect that polish to data. When every element on every screen is intentionally designed to move users toward the outcome that generates revenue. When activation improves with each sprint because the design decisions are informed by user behaviour, not taste.

That's the gap between "clean" and "converting" — and closing it is a system, not a redesign.

Honest Comparison

ProductQuant vs. Other Options

We're not the right fit for everyone. Here's how we compare.

ProductQuant Freelance Designer Design Agency In-House Team
What you get Data-driven redesign + A/B tested results Mockups + UI polish Brand refresh + design system Ongoing design capacity
Measures success by Conversion lift + activation rate Client approval Deliverables completed Velocity / output volume
Time to measurable impact 4-6 weeks Never (not measured) 3-6 months Varies widely
Uses behavioural data Heatmaps, sessions, A/B tests Rarely Sometimes (extra cost) If they have the tools
Cost (3 months) $20K–$40K (sprint) $15K–$30K $60K–$150K $90K–$180K (salary + tools)
What happens after You own the system + design library You get Figma files Dependency continues Ongoing cost

Note: If you need ongoing UI production (icons, marketing pages, feature screens), a freelance designer or in-house team is the better fit. If you need a full brand overhaul, an agency makes sense. If your product converts poorly and you need data-driven design that moves metrics, we're your best option.

Run your own numbers

Every signup you paid to acquire hits your onboarding flow. Some activate. Some don’t. The gap between your current activation rate and where it could be — that’s revenue you’ve already paid for and aren’t capturing.

You know the numbers for your product. Run the math: signups per month × the activation gap × your ACV. That’s what’s sitting on the table every month.

And that’s just activation. Your pricing page, feature adoption, and upgrade flows each have their own gap between current and possible.

4–6 weeks from now, the highest-impact flow could be redesigned, A/B tested, and converting. Or the gap stays where it is. Your call.

Who You're Working With

Not an agency. Not a hire. A partner.

Jake McMahon
Jake McMahon — Product Design & Growth Strategist
I'm Jake, the founder of ProductQuant. I've spent the last 8 years as a product operator at B2B SaaS companies from $1M to $50M ARR. Not a visual designer. Not a UI contractor. A product person who treats design as a growth lever.
I started this practice because I kept seeing the same failure mode: companies hire designers who make things look better, but nobody measures whether "better-looking" actually moves the needle. The redesign ships, the team celebrates, and 3 months later the board asks why conversion hasn't changed.
What I won't do:
  • Redesign without friction data — every change needs a reason backed by user behaviour
  • Make it "prettier" without measuring whether "prettier" converts better
  • Deliver a Figma file and disappear — we ship, test, and measure
  • Recommend a full redesign when 3 targeted flow fixes would move the metric
What I will do:
Redesign the flows that move activation and retention metrics. Quantify every friction point, redesign the highest-impact ones with session data, and A/B test the changes. Hand you a design system your team can maintain and iterate on. And if the friction analysis shows your design isn't the problem — I'll tell you what is, and we won't waste your money redesigning something that isn't broken.
Risk Reversal

Four commitments. Zero risk.

We measure success in conversion lifts, not deliverables. Our commitments reflect that.

Conversion Lift Guarantee

If your redesigned flow doesn't show measurable conversion improvement within 60 days, we iterate free until it does. We don't ship "redesigns" — we ship results.

Data-Backed Decisions

Every design change comes with the data that justified it. Session recordings, heatmaps, funnel analysis. No "I think this looks better" — only "the data shows this converts better."

Design System Handoff

You get a complete component library, pattern documentation, and usage guidelines. Your team can maintain and extend everything without us. No vendor lock-in.

A/B Test Results

Every major design change is validated with A/B testing before full rollout. You see the statistical significance, the conversion delta, and the projected revenue impact before committing.

Common questions

Everything you need to know before booking a call.

Do you replace our design team? +
No. We complement them. We bring the data layer — friction analysis, A/B testing methodology, conversion measurement — that most design teams don't have time or tooling to do themselves. After the engagement, your team has the frameworks and design system to continue on their own.
What tools do you use? +
Figma for design. Hotjar or FullStory for session recordings and heatmaps. PostHog, Amplitude, or Mixpanel for funnel analytics. LaunchDarkly or Statsig for A/B testing. We adapt to whatever your stack already uses — we're not going to make you buy new tools.
How do you measure success? +
Conversion rate of the redesigned flow, before and after. Activation rate change. Onboarding completion improvement. Time-to-value reduction. Every engagement has a baseline measurement in week 1 and a comparison measurement post-deployment. We agree on the target metric before we start designing.
What if our analytics aren't set up properly? +
That's common — and it's part of what we fix in Phase 1. The Design Impact Assessment includes an instrumentation audit. If your event tracking has gaps, we'll flag them and help your engineering team patch the critical ones before we start measuring. You can't improve what you can't measure.
What happens after the sprint? +
You have redesigned flows live in production, A/B test results proving they work, and a design system your team can build on. Most clients continue into Design OS ($12K-$18K/mo) to tackle additional flows. Some take the system and run it internally. Both work — you own everything.
Do you write code or just deliver designs? +
We deliver production-ready designs with detailed specs, component libraries, and developer handoff documentation. We work closely with your engineering team during implementation and QA. We don't write your production code, but we make sure what ships matches what we designed — pixel-perfect.
