The gap between signup and first value closed — measurably, sprint over sprint.

CONVERSION
TRACKED

Every flow redesign has a before-and-after metric. No more designing by opinion.

REVENUE
ATTRIBUTED

Activation, churn, and expansion moved by design decisions you can point to. Not just prettier UI.

Design decisions that can't be tied to revenue metrics aren't design decisions — they're opinions with a budget attached.

Most design work is evaluated on aesthetics: does it look good, does the team like it, does it feel on-brand. None of that answers the question your CFO asks. The difference between design as a cost centre and design as a growth lever is whether every change has a measurable hypothesis behind it — and a metric to validate it against after it ships.

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, design decisions default to opinion instead of data. 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 quantified friction is your revenue ceiling — and we show you exactly where it is.

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 upgrade flow 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.

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

The Framework

The D.R.I.V.E. framework. From friction audit to shipped redesign in 4–6 weeks.

Every design decision backed by user behaviour data. Every flow change A/B tested before full rollout. You see what moved and by how much.

Week 1–2

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)
Week 1–2

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
Week 3–4

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
Week 4–5

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
Week 5–6

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

Six disciplines. Every one tied to a conversion or activation metric.

Your pricing page, upgrade modal, and checkout flow are doing revenue work right now — or bleeding it. Conversion design is the discipline that finds exactly where users drop, quantifies the cost, and redesigns those moments to close the gap between intent and action.

  • Pricing page redesign — hierarchy, anchoring, CTAs
  • Upgrade and upsell flow friction removal
  • CTA audit and click-through rate optimisation
  • Free-to-paid conversion funnel redesign
  • Modal and interstitial design for upgrade moments
  • Landing page conversion rate optimisation

Turning the gaps between intent and action into revenue

Every drop-off point in your funnel has a design root cause. We find it, quantify it, and fix it — with measurable before-and-after conversion data.

Most SaaS products lose the majority of signups before users see the value the product promises. A well-designed onboarding flow maps the shortest path to the first aha moment — and removes every piece of friction standing between signup and activation.

  • First-session flow mapping and friction audit
  • Empty state design for blank-slate products
  • Progressive disclosure and step-by-step guidance
  • In-app tooltip and contextual help design
  • Onboarding checklist and milestone design
  • Welcome email sequence and in-app messaging alignment

Getting more signups to their first moment of value

The shortest path from signup to activated user is a design problem. We map it precisely, remove the friction points, and build the flows that turn new signups into engaged users.

Activation is the moment a user realises your product does what they hoped it would. Most products have one — but the path there is full of unnecessary steps, unclear cues, and friction that erodes confidence. Activation path design clears the route and signals progress at every step.

  • Aha moment identification and instrumentation
  • Feature discovery UX — surfacing value in context
  • Progressive disclosure and feature gating design
  • Activation metric definition and UI feedback loops
  • Habit formation loops and re-engagement triggers
  • Notification and nudge design tied to user behaviour

A product that shows its value before users give up looking

We design the paths that lead users to your product's most valuable moments — faster, with less friction, and with enough feedback to keep them moving forward.

Most A/B tests fail not because the hypothesis was wrong but because the test was under-powered, the metric was wrong, or the implementation introduced confounding variables. Rigorous experiment design means fewer tests, better decisions, and results your team actually trusts.

  • Hypothesis design from behavioural and funnel data
  • Sample size and statistical power calculation
  • Control/variant specification and design
  • Test implementation review and QA
  • Results analysis with confidence intervals
  • Multivariate test design for complex flows

Experiments that produce decisions, not just data

We design tests that are statistically sound, properly implemented, and analysed with rigour. The result is a decision your team can act on — not a p-value to debate.

A design system is a velocity multiplier — when it exists. Without one, every new feature takes twice as long, consistency erodes sprint by sprint, and the design-to-engineering handoff becomes a negotiation. A well-built system lets your team ship faster and maintain quality as you scale.

  • Component library design and documentation
  • Design token architecture (colour, spacing, type)
  • Figma component library build and maintenance
  • Design-to-code handoff specification
  • Usage guidelines and governance documentation
  • Design system audit and gap analysis

The infrastructure that lets your team ship faster at scale

A design system is not a deliverable — it's infrastructure. We build the component libraries, tokens, and governance that let your team move faster without sacrificing consistency.

Session recordings, heatmaps, and usability tests tell you things analytics never can — why users do what they do, what they're looking for, and where the interface is failing them. UX research turns behavioural observation into design decisions your whole team can act on.

  • Session recording analysis (PostHog, FullStory, Hotjar)
  • Heatmap and click-map interpretation
  • Moderated and unmoderated usability testing
  • User interview design and synthesis
  • Cognitive walkthrough and expert review
  • UX audit with prioritised findings report

Behavioural evidence that makes every design decision defensible

We watch what users actually do — not what they say they do. Every design recommendation is grounded in observed behaviour, not stakeholder preference or designer intuition.

Before we redesign anything, you know exactly what’s costing you conversions.

The Design Impact Assessment runs in week 1. It maps every friction point, quantifies the revenue cost of each, and produces a prioritised list of exactly what to fix first — ranked by impact, not designer intuition.

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

Friction Points

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

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

Design Debt

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

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

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

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

Every design sprint includes a measurable hypothesis. If a shipped redesign doesn't produce a statistically significant conversion lift within the test window, we continue iterating at no additional cost until it does.

Your design looks clean. The question is whether it converts.

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.

How We Compare

ProductQuant vs. the alternatives

We’re not the right choice for every team. Here’s an honest breakdown.

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 This Is For

This works for product teams where design decisions are tied to metrics — or where they should be.

Good fit

  • You have a product with measurable activation and conversion metrics
  • You want design decisions tied to friction data, not opinions or instinct
  • You're ready to run A/B tests and track results with PostHog or Amplitude
  • Your design team wants to be measured on impact, not aesthetics
  • You can move on a 4–6 week sprint cadence without enterprise procurement delays

Not the right fit

  • You want a brand refresh or visual redesign with no product metrics attached
  • You're looking for a full-time designer as a long-term hourly contractor
  • You don't have product analytics in place and aren't willing to set it up
  • You need UI/UX support inside a 90-day enterprise procurement cycle
  • You evaluate design quality by how much the team likes the colours
Who You’re Working With

A product operator who measures design by conversion rate, not client approval.

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.
What We Commit To

Four commitments. Written into the scope before we start.

We measure success by conversion lift, not deliverables completed. 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 owns the design system and can iterate independently after handoff.

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.

What most people ask before booking a call.

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.
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.
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.
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.
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.
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.

Your highest-impact flow could be redesigned, tested, and converting in 4–6 weeks.

We start by mapping exactly what’s costing you conversions. You leave the first call with a friction analysis and a prioritised list of what to fix first.
