Most portfolio companies at the growth stage build products based on sales requests and founder intuition rather than structured user research. Design is reactive – fixing UI problems after they cause churn. We bring product design and research discipline that aligns what you build with what users actually need, reducing wasted engineering time and improving the metrics that drive exit valuation.
The Problem
Engineering builds features based on the loudest customer, not user research
Without structured product research, the roadmap is driven by whoever yells loudest – a churning enterprise customer, a board member's pet idea, or the sales team's latest lost deal. This produces a bloated product that does many things poorly instead of a few things well. For PE/VC portfolio companies heading into diligence, every sprint spent on the wrong feature is a sprint not spent on the metrics buyers actually underwrite: retention, activation, expansion revenue. Research eliminates the guesswork.
Poor UX creates friction that shows up as churn and support costs
Portfolio companies at the growth stage often carry design debt from their early product. Confusing navigation, inconsistent UI patterns, slow workflows, and mobile-unfriendly interfaces create friction that users tolerate until they find an alternative. The cost of this friction is hidden in churn data and support ticket volume. For PE/VC-backed companies trying to improve net revenue retention ahead of a hold-period review, UX problems are a tax on growth that increases with every new customer.
No design system exists, so every new feature looks and works differently
Without a design system, every engineer and designer makes independent decisions about components, spacing, color, typography, and interaction patterns. The result is an inconsistent product experience that feels unprofessional and confuses users. For portfolio companies moving upmarket or competing against well-funded incumbents, this inconsistency is a competitive disadvantage. A design system also slows engineering velocity because developers rebuild common components instead of using a shared library.
The company has outgrown its designer but can't justify a full design team
Many portfolio companies have a single designer – often a junior hire or a generalist who handles everything from product UI to marketing materials. The company needs senior design thinking, user research expertise, and design system architecture, but can't justify the cost of a full design team at its current stage. The gap between what the product needs and what the design resource can deliver grows wider every quarter, and it usually surfaces publicly during buyer diligence, not internally.
How We Help
We start with a product design and research audit that evaluates your current user experience, identifies usability problems, and maps user pain points to business metrics. This includes heuristic evaluation of key product flows, analysis of user behavior data, review of support tickets and churn reasons, and competitive UX benchmarking. The audit produces a prioritized list of design improvements ranked by expected impact on retention, activation, and user satisfaction.
User research is the foundation of everything we do. We run structured research programs – user interviews, usability testing, surveys, and behavioral analysis – that give your team direct insight into how customers actually use your product, where they struggle, and what they need. For PE/VC portfolio companies, we focus research on the questions that connect to business outcomes: why do users churn, what drives activation, where do upgrade decisions happen, what prevents expansion. Research findings are presented as actionable recommendations, not academic reports.
From research findings, we design solutions. Our design team works in your existing product workflow – designing in Figma, participating in sprint planning, delivering specs to engineering, and iterating based on feedback. We handle the full design cycle: information architecture, wireframing, visual design, interaction design, prototyping, and usability validation. Every design decision is grounded in research data and aligned with your growth objectives.
Design system development creates the infrastructure for consistent, scalable product design. We build component libraries, define design patterns, document usage guidelines, and create the Figma and code assets that enable your engineering team to ship consistent UI without waiting on design for every feature. The design system accelerates development velocity while maintaining quality – a combination operating partners value because it shortens time-to-market for new features and reduces the design debt a buyer would flag in diligence.
We also bring design strategy to product planning conversations. Before features are specced and built, we help evaluate whether they solve the right problems, connecting product decisions to research data and prototyping concepts before committing engineering resources.
For PE/VC firms with multiple portfolio companies, we run design maturity assessments across the portfolio, identifying which companies need design investment, where UX is creating growth drag, and which design approaches to replicate.
Measurement connects design work to business outcomes: task completion rates, time-on-task, error rates, and satisfaction, tracked alongside activation, feature adoption, retention, and NPS. Monthly reports show how design improvements move the metrics operating partners and boards track.
What we deliver
- Product design and UX audit with prioritized improvement roadmap
- User research program with structured interviews, usability testing, and behavioral analysis
- Design system with component library, pattern documentation, and Figma assets
- Product design execution embedded in sprint cycles with research-backed specifications
The portfolio companies that retain customers best going into 2026 aren't the ones with the most features — they're the ones where every feature actually works well for the user.
Our Methodology
Our product design and research engagements follow a 90-day sprint model. The first 30 days focus on audit and research: we evaluate the current UX, run initial user research, and identify the highest-impact design improvements. We also assess design system needs and present a prioritized design roadmap to leadership.
Days 30-60 focus on design execution and system building. We redesign priority flows based on research findings, launch the design system, and begin usability testing on new designs. We work in iterative sprints, shipping design improvements weekly and validating them with real users. This phase also includes training engineering on the design system.
Days 60-90 focus on optimization and enablement. We refine designs based on usability test results, expand the design system, and train internal team members on research methodology and design process. By day 90, the portfolio company has improved key product flows, a functional design system, a research program that keeps generating insight, and measurable improvement in user experience metrics.
How We Work
Product design engagements start with a 2-week audit and research phase. We evaluate the product UX, run initial user interviews, and analyze behavioral data. We present findings and a design roadmap to leadership and operating partners.
Weeks 3-10 focus on design execution. Our team includes a senior product designer who owns design strategy and execution, a UX researcher who runs studies and synthesizes findings, and a design system engineer who builds the component library. This team participates in your product sprints, attending planning sessions and standups.
From month 3, we shift to optimization and knowledge transfer. We document design principles, train internal designers and PMs on research methods, and make sure engineering has actually adopted the design system, not just received it.
Clients should expect a research-driven process that sometimes challenges assumptions. User research frequently reveals that the features leadership prioritizes aren't the ones users value most. We present findings honestly and help the team make product decisions based on evidence rather than opinion.
- User experience improvement and usability metrics
- Product activation and retention rate improvement
- Design system adoption and development velocity increase

Frequently asked questions
How much does product design and research cost for PE/VC portfolio companies?
Product design and research engagements typically run $20,000 to $50,000 per month depending on scope – design execution only, research only, or a combined program with design system development. That's less than hiring a senior product designer and a UX researcher separately, and it delivers impact faster because we bring proven methodology on day one. For PE/VC firms deploying design support across the portfolio, we offer portfolio pricing.
How long before we see results from product design and research?
Research insights from the first round of user interviews are available within 2-3 weeks. Design improvements to priority flows ship within 4-6 weeks. Measurable impact on activation and retention metrics typically appears within 60-90 days, once redesigned flows reach enough users to produce statistically meaningful data. The design system takes the full 90 days to build but starts accelerating development velocity as soon as the first components ship.
How does the product design and research team integrate with our existing portfolio company staff?
We embed directly in your product and engineering workflow. Our designer joins sprint planning, works with your engineers on implementation, and uses your existing design tools. Our researcher coordinates with your PM on research questions and shares findings in formats your team can act on immediately. We work alongside your existing designer, not as a replacement – adding capability where it's thin.
What makes Winston Francois different from a traditional product design agency?
Design agencies optimize for visual polish. We optimize for business metrics. Every design decision we make is grounded in user research and tied to activation, retention, or revenue outcomes. We understand PE/VC dynamics – fund timelines, the metrics that drive valuation at exit, and the need to build internal design capability rather than permanent agency dependency. We also bring research discipline most design agencies skip.
How do you measure ROI from a product design and research engagement?
We track usability metrics that connect directly to business outcomes: task completion rates, onboarding completion, activation rates, feature adoption, and user-reported satisfaction. We measure before-and-after on redesigned flows and attribute retention and activation gains to specific design changes. Monthly reports show operating partners how the design investment is moving the growth metrics they already track.
What type of PE/VC portfolio company is the right fit for this service?
The best fit is a portfolio company with an established product and user base where UX issues are contributing to churn, low activation, or competitive disadvantage. Companies that grew fast without investing in design – where the product works but doesn't work well – see the most immediate impact. If support fields UX-related tickets regularly, onboarding completion is low, or users cite ease of use as a reason for leaving, design investment produces measurable returns.
