Ryan Wiggins’ path: customer support to growth leader at Mercury
Ryan shares how an unexpected SQL class in a Facebook customer support role reshaped his career toward growth. He explains his time in Facebook’s growth marketing org and what drew him to Mercury’s product-led approach to banking for startups.
- •Learning SQL in support sparked a data-driven mindset and surfaced “growth” work before it was a formal role
- •Facebook growth marketing as the intersection of data, product, and marketing
- •Work across Facebook products including WhatsApp; desire to tackle earlier-stage problems
- •Why Mercury’s product quality made joining an easy decision
- •Mercury scaling to 100K+ startups and building a strong analytics foundation
- 2:06 – 3:47
Career navigation beyond brand-name logos: curiosity, compounding skills, and “blossom where you’re planted”
Ryan responds to the idea that career progress depends on prestigious logos. He outlines two principles—pursuing curiosity to add value and deliberately closing skill gaps toward a chosen direction—that helped him create opportunities despite an unplanned path.
- •Growth wasn’t a defined job early in his career; his path was largely unplanned
- •Use curiosity to create value in whatever role you’re in
- •“Blossom where you’re planted” as a strategy for generating options
- •Pick a role/person you want to become; identify and close the skill gap
- •Progress compounds even if you later change direction
- 3:47 – 6:04
Why WhatsApp scaled so far with so little process: product-market timing, simplicity, and adding fuel
Ryan contrasts WhatsApp’s lean team and limited analytics footprint with Facebook’s data-heavy culture. He breaks down WhatsApp’s early growth into three drivers: perfect market timing, ruthless focus on reliability, and amplifying what worked via partnerships and viral features.
- •Joined WhatsApp in 2017: massive scale with minimal PM/data staffing
- •Right product/right market: smartphones/app stores emerging; SMS expensive globally
- •Simplicity + reliability as the core product strategy (never going down)
- •Early carrier partnerships (free data packs) created a virtuous adoption loop
- •Layering features like calling to intensify person-to-person engagement
- 6:04 – 8:00
Growth isn’t uniform: S-curves by country and why the U.S. was hard
The conversation shifts from aggregate growth curves to market-by-market dynamics. Ryan explains that some regions (notably India) drove outsized growth while the U.S. faced structural headwinds from cheap SMS and entrenched competitors like iMessage.
- •Overall trajectory looked linear, but country-level curves varied significantly
- •India smartphone expansion was a major tailwind and later became saturated
- •The U.S. showed periods of flat or negative growth
- •Cheap/included SMS reduced WhatsApp’s value prop versus other markets
- •Competition: iMessage, robust SMS habits, and other messaging incumbents
- 8:00 – 8:47
The three-part foundation of sustainable growth: product, customer understanding, execution loop
Ryan explains how WhatsApp’s success reframed his thinking: data is valuable, but not sufficient. He emphasizes that great products, deep customer empathy, and a disciplined growth execution loop together drive compounding outcomes.
- •Data-light origins don’t mean data is irrelevant; it can unlock major improvements later
- •Examples of impact: WhatsApp Business scaling and targeted market growth (e.g., France)
- •Three essentials: great product, deep customer understanding, strong execution loop
- •Customer understanding can come from data and/or direct empathy
- •Combining the three creates the conditions for global-scale products
- 8:47 – 9:26
What an excellent growth loop looks like: boosters on a retentive core
Ryan defines an “incredible growth execution loop” as systematically identifying what fuels adoption and then amplifying it. He frames growth as a system built on a retentive product, powered by coordinated product experiences, marketing, and sales/partnerships.
- •Start with a product that delivers real value and retains users
- •Growth levers come from product, marketing, and partnerships/sales working together
- •Focus on the dynamics that “pour fuel on the fire”
- •Treat growth as an interdependent system, not a single channel
- •Execution is about iterating toward scalable levers
- 9:26 – 10:28
What leaders (and growth teams) get wrong: over-indexing on acquisition and “100 hacks”
Ryan challenges the common misconception that growth equals acquisition. He argues teams must diagnose the full funnel, sequence fixes correctly (often retention first), and avoid superficial tactics like endless notifications instead of solving core product problems.
- •Leaders often ask for acquisition when the real issue is conversion/activation/retention
- •Sequencing matters: fix bottom-funnel leaks before scaling top-funnel spend
- •Growth people often default to notifications/upsells rather than product experience
- •Most results typically come from one or two big levers, not dozens of small hacks
- •Aim for angle-changing improvements, not minor step-change optimizations
- 10:28 – 13:44
Case study: WhatsApp Business retention fix before acquisition (and the “right moment” invite)
Ryan illustrates funnel-first diagnosis with WhatsApp Business, where retention was collapsing due to a broken transition from the consumer app. He also shares a WhatsApp consumer example showing that the best invite prompt is the one embedded in the user’s immediate intent.
- •WhatsApp Business: acquisition push was premature because retention was extremely low
- •Root cause: migration issues (lost chats) made the product unusable for businesses
- •Fixing the transition doubled retention and changed the growth trajectory
- •Consumer growth insight: users churn when they have no one to message
- •Best invite entry point was contextual: when searching for someone not on WhatsApp
- 13:44 – 15:09
Choosing the right success metric: retention curves, leading actions, and the ‘one person’ insight
Ryan explains how to identify the metric that defines a successful user by linking early actions to long-term retention. For WhatsApp, the proxy wasn’t simply “more contacts,” but increasing the likelihood a user can reach the one person they truly want to talk to.
- •Start with retention curves to understand who sticks and when drop-off happens
- •Correlate early behaviors with long-term retention to find leading indicators
- •WhatsApp insight: value comes from reaching the person you want to talk to
- •Use proxies (more contacts increases likelihood of that key person)
- •Classic framing: Facebook’s “10 friends in 14 days” as an action tied to core value
- 15:09 – 18:06
Operating a high-velocity growth team: explore/exploit, experiment sizing, and input vs output metrics
Ryan outlines what makes growth teams distinct: speed, tight scope, and rapid learning loops. He discusses statistical considerations for experiments, why early-stage teams should target large wins, and how leading (input) metrics help judge experiments before lagging outcomes appear.
- •Speed differentiates growth teams: tightly scoped hypotheses and fast iteration cycles
- •Operate in explore → exploit mode: quick bets, then double down on what works
- •Early-stage focus: look for 50%/2x gains rather than 1% optimization
- •Use sample size calculations to decide if an experiment is measurable at all
- •Track input metrics (leading behaviors) vs output metrics (downstream results)
- 18:06 – 22:20
When to hire growth—and what the first growth leader should do in weeks 1–4
Ryan argues you hire growth once you have product-market fit and at least one stable, repeatable acquisition channel; before then, the CEO effectively is the growth PM. He also provides a practical playbook for a first growth leader: walk the journey, diagnose channels and funnels, identify success actions, then ship something to learn how execution really works.
- •Hire growth after PMF + at least one consistent channel; growth can’t create demand from nothing
- •If not ready, the whole company is the growth team and the CEO is the growth PM
- •First growth leader should do an end-to-end customer journey walkthrough (with screenshots)
- •Run foundational analyses: source/channel trends, intent→activation funnel drop-offs, success-action discovery
- •Ship an early change to reveal organizational friction and build a repeatable execution process
- 22:20 – 26:02
Building and scaling the org: lean teams, repeatability tests, and maximizing working channels
Ryan explains why smaller teams often move faster, invoking Metcalfe’s law to highlight coordination costs. He emphasizes proving repeatability beyond founder-led efforts, prioritizing what’s already working, and expanding only when diminishing returns justify shifting focus.
- •Lean teams (1–4 people) keep communication tight and iteration fast
- •Coordination complexity grows quickly as headcount increases
- •Proof of “working” means repeatability beyond founder-led sales or forced effort
- •Test robustness by pulling back spend/effort and seeing if organic signals persist
- •Prioritize improving working channels before trying to resurrect non-working ones; watch diminishing returns
- 26:02 – 43:48
Hiring great growth talent: non-obvious backgrounds, interview signals, comp, onboarding, and postmortems
Ryan shares where to find strong growth operators (often in overlooked operational roles), what traits matter most, and how to structure interviews and case studies. He then covers compensation ranges, onboarding expectations, early red flags, when to make a call on performance, and why he prefers continuous review over formal postmortems for growth work.
- •Best ‘hidden’ talent: change agents from ops/support roles with scrappiness and customer empathy
- •Core hiring signals: ability to ship through constraints, analytical problem breakdown, product sense/taste
- •Avoid ‘free work’ feeling in case studies; keep prompts general vs today’s internal problem
- •Comp: prioritize meaningful equity (‘skin in the game’); US cash range cited ~150–250k + equity for early senior ICs
- •Onboarding: month 1 context and relationships; by month 3 expect opinions, shipped improvements, and strategic clarity; prefers ongoing monthly reviews over one-off postmortems
- 43:48 – 46:33
Experimentation at WhatsApp: building A/B testing to measure downside risk (plus France growth playbook)
Ryan recounts WhatsApp’s surprising reality: it reached 1.5B users without A/B testing infrastructure. When business features introduced potential trust risks, the team built privacy-safe experimentation primarily to detect negative impacts; he also summarizes how WhatsApp applied a product/marketing/partnerships playbook to accelerate growth in France.
- •WhatsApp scaled to 1.5B users without A/B tests or experimentation framework
- •A/B testing was built later to detect potential negative impacts of business messaging features
- •Network effects products need early warning—if harm becomes visible at scale, it’s often too late
- •Framework built in a privacy-safe way; results showed no meaningful negative impacts for tested features
- •France growth: combined product invites, new marketing campaigns, and novel partnerships over ~1 year to gain share
- 46:33 – 50:24
Quick-fire principles: timeless tactics, dying channels, and a growth strategy to admire
In rapid Q&A, Ryan distills enduring growth truths and what’s becoming less effective. He warns that overusing push/email creates channel blindness, argues founders underestimate the sustained-system nature of growth, and praises Substack for aligning incentives and leveraging network features like recommendations.
- •Timeless: connect users to the key actions that make them stick (sustainable activation)
- •Dying/overused: push and email spam lead to blindness and permanent channel loss when users opt out
- •Founder mistake: expecting a single campaign to ‘solve’ growth instead of building a system over time
- •What he’d change: more customer conversations in growth practice
- •Impressed by Substack: incentive alignment with writers + network-driven recommendations and product expansion
