Turning insight
into outcomes
I translate user insight into company-level strategy and measurable business
outcomes.
At Meta, Google, and Etsy I've driven qualitative & quantitaive research and built high-performing teams to establish strategic vision, implement measurement & experimentation systems,
make high-stakes investment decisions, and scale impact through cross-functional, executive influence. I'm passionate about building things that actually help people.
Case Studies
A two-phase global research programme that identified the right verification documents for key markets — reducing failure rates from ~90% to 72% in Brazil and Indonesia.
Identified a misaligned team metric, built the business case for change, and designed an end-to-end measurement programme — shifting an entire product team's north star from activity counts to genuine user support.
Qualitative research into user mental models around Germany's NetzDG law — and data-driven advocacy to a government regulator when a mandated implementation caused a 13% drop in high-severity content reporting.
Built a cost data infrastructure from scratch, then ran a competitive benchmark study across five platforms — revealing Horizon OS as a major outlier, with 91% of apps losing money, and redirecting the developer funding programme accordingly.
A large-scale quantitative study across five markets mapping the developer journey from awareness to intent — revealing a critical undecided segment and a messaging mismatch that was leaving the strongest conversion levers unused.
Note: Due to confidentiality constraints, all data, percentages, diagrams, and visualizations are directionally representative, not exact reproductions.
Bryan Carroll
I'm a User Experience Researcher with a track record of turning ambiguous research questions into decisions that actually move products forward. My work sits at the intersection of deep qualitative understanding and rigorous quantitative methods — I design programmes that generate both the insight and the confidence needed for teams to act.
I've led research at scale for Meta, Google, and YouTube — working across content integrity, account management, advertising, and productivity tools. I'm equally comfortable conducting in-person interviews in Indonesia and running regression analysis.
What I find most rewarding is influencing not just what gets built, but how teams think about users. I've helped teams replace flawed metrics, shift roadmap priorities, and build genuine empathy for people they'd never met.
Experience & Skills
Reallocated $XXM in annual investment within Reality Labs by identifying gaps in VR developer ROI through market research, in-product data, and qualitative insights, pivoting the content funding strategy to increase the likelihood of successful third-party titles. Built and scaled a 30-person research team's quality systems, raising the bar on insight delivery and improving consistency and downstream impact.
Defined and landed new vision, mission, and strategy for a 150-person org in partnership with Product, Engineering, Design, and Data Science leadership. Increased Meta usage by 0.2% through implementation of a user-centric measurement framework. Led cross-company efforts to operationalise incoming regulations, resolving a previously unexplained 13% increase in unreported high-severity content by reframing solutions around user mental models.
Reduced prevalence of high-severity content through an international qualitative and quantitative programme that improved tooling, leading to a ~67% increase in high-severity takedowns. Prevented negative business outcomes by leading concept testing that enabled a stop-the-line decision on a feature projected to reduce sentiment by ~11%, while unblocking alternatives that improved sentiment by ~6%.
Drove $1M incremental revenue through a new ad targeting objective by identifying user and advertiser requirements, aligning cross-functional partners, and supporting launch. Accelerated 0-to-1 product delivery for a new ad creation experience by prioritising critical requirements through research, enabling MVP launch in under two months.
Led buyer-side research strategy supporting end-to-end purchase funnel optimisation. Standardised recruiting processes and screeners, improving participant quality and reliability across studies.
Designed and scaled the YouTube Pro Series, a high-production hybrid learning programme reaching 150,000+ creators and expanding internationally (UK, Japan). Launched and led YouTube Space NYC, owning service design, value proposition, success metrics, and operational outcomes. Established the Creator Feedback Forum, a recurring executive-facing signal channel that informed product features and creator initiatives.
Reduced time-to-market by 20% for a global hospitality brand through org-wide diagnostics and capacity assessment, freeing 7% additional operational capacity. Drove 7% cost reduction for a national pharmacy by identifying back-of-house inefficiencies through work sampling study.
