A versatile marketing professional across healthcare/medtech, consumer tech, and beauty.

Selin Ergun

I'm a versatile marketing professional with 9+ years experience spanning healthcare/medtech, consumer tech, and beauty — someone who's equally comfortable building payor and channel materials for a regulated CGM launch as I am running influencer strategy for a beauty brand or leading executive PR for a Fortune 500 company.

Over the past several years, I've moved from communications and PR (Match Group/Tinder) into content strategy and team leadership (Flora), into full-funnel influencer and PR ownership (Drybar), and most recently into full-stack payor and channel marketing for medical device launches (Dexcom). Each move added a new capability without leaving the last one behind. I still write, still manage people and partners, still think about press and brand, and now I also navigate the more technical, cross-functional demands of healthcare marketing.

What ties it together: I move fast in ambiguous, matrixed environments, translate complex or regulated information into clear materials, and manage both people (direct reports, coordinators, interns) and cross-functional stakeholders (designers, PMs, agencies, legal/medical review) to get launches out the door on time.

I'm currently exploring senior marketing roles in tech and AI — spaces where I can bring this range to bear on products that matter.

Selected work

Nine case studies
01

Dexcom — G7 15 Day: Payor & Channel Launch Support

Associate Marketing Manager, Global Market Access | Dexcom

Supporting the U.S. launch of Dexcom's longest-wearing CGM, coordinated across payor and channel funnels. G7 15 Day launched December 1, 2025, available first through DME providers with Medicare coverage as a key access point — requiring materials built for a more complex funnel than a typical consumer launch.

My role

Coordinated production of launch materials across the payor/channel workstream, working within a cross-functional structure (weekly check-ins, project management, multiple stakeholders) to keep materials aligned to launch timing and compliant with payor/DME channel constraints.

Context

G7 15 Day has an 8.0% MARD accuracy rating. Dexcom's Q4 2025 results (13% YoY growth) cited G7 15 Day and expanded access as contributing factors.

What this demonstrates

Ability to produce channel-specific materials at speed, navigate regulated/reimbursement-sensitive content, and manage production across multiple stakeholders under launch deadlines.

02

Dexcom — Leading Conference Portfolio Strategy at Scale

Associate Marketing Manager, Global Market Access | Dexcom

What started as conference logistics support has grown into full ownership of the conference portfolio for Dexcom's Global Market Access team — a program spanning 75+ conferences annually and a budget exceeding $1M. I independently manage the entire process: from monthly and quarterly budget phasing to leading 2027 strategic planning with stakeholders across Finance, Marketing, Legal, Sales, and Procurement.

The challenge

Dexcom's conference footprint spans major industry events (ADA, ATTD, AMCP, PCMA, ASHP Midyear, Asembia, HLTH, VIVE, HIMSS, APhA, Nexus, NACDS TSE, and more) each with its own budget, timeline, sponsorship terms, and cross-functional dependencies. At this scale, the program needed more than execution: it needed a single owner who could track spend in real time, forecast forward, and give leadership a clear picture to make investment decisions on. There was no one doing that end-to-end. I stepped into the gap.

Budget tracking & phasing

Monthly and quarterly review of spend against a $1M+ portfolio, with responsibility for phasing decisions that inform how budget is allocated across the year.

Cross-functional stakeholder alignment

Running quarterly budget reviews with representatives from Finance, Marketing, Legal, Sales, and Procurement, translating a fragmented, multi-team process into a single coordinated review cadence.

Process ownership

Rebuilt and significantly improved the tracking process for the full portfolio, replacing what had been an informal or fragmented system with a structure that scales to 75+ conferences without additional headcount.

Impact

Sole owner of a $1M+, 75+ conference program for the Global Market Access team — no team, no backup, full accountability for accuracy and outcomes. Built a planning process in 2025 from the ground up, giving leadership a forward-looking view they didn't previously have. Became the connective tissue across 5 functions (Finance, Marketing, Legal, Sales, Procurement), each with different priorities and constraints. Improved portfolio tracking accuracy and visibility, reducing the manual reconciliation that used to happen ad hoc across teams.

Forward-looking strategic planning

Leading 2027 conference planning a year ahead of execution: building the framework stakeholders use to prioritize which conferences to invest in, scale back, or cut.

Why this matters

This work reflects a shift from doing to owning: instead of executing tasks assigned by others, I'm the person leadership relies on to know where the program stands, what trade-offs are on the table, and what to do next. Running a $1M+, 75-conference portfolio solo, while also facilitating alignment across five functions, is the kind of scope typically split across a team of two or three.

03

Dexcom — Owning Team Communications Across a Cross-Functional Org

Associate Marketing Manager, Global Market Access | Dexcom

As my scope grew, so did my ownership of how my team communicates. I now own team communications end-to-end: leading a quarterly newsletter, coordinating recurring scorecards and leadership updates, and translating priorities from multiple stakeholders into clear, actionable updates. I track follow-through and make sure the right information reaches the right audience at the right time. This isn't a formal title; it's a function I built because the team needed it.

The challenge

Cross-functional initiatives generate a lot of information (decisions, timelines, blockers, updates) scattered across teams, agencies, vendors, and leadership. Without someone actively synthesizing and routing that information, priorities get lost, follow-through slips, and leadership loses visibility into what the team is actually accomplishing. There was no dedicated owner of that flow. I built the structure to own it.

Creating visibility

Own and coordinate recurring team communications, including a quarterly team newsletter, scorecards, and leadership updates, synthesizing input from multiple stakeholders into concise, actionable summaries that make the team's work visible across the organization.

Driving alignment

Serve as the connection point between leaders, team members, agencies, vendors, and cross-functional partners, keeping everyone informed on decisions, timelines, and next steps to reduce confusion and keep initiatives on track.

Influencing without authority

Lead communications for complex, multi-stakeholder initiatives without formal authority over every participant using clear, consistent communication to build consensus and keep diverse groups moving in the same direction.

Creating structure

Established recurring communication cadences that keep the team organized and accountable: proactively gathering updates, following up on open action items, and ensuring commitments actually get completed.

Impact

Became the default point of coordination for a team spanning internal stakeholders, agencies, and vendors: the person people go to for "where do things stand?" Built recurring reporting infrastructure (scorecards, newsletters, leadership updates) that gives leadership consistent visibility into team priorities and wins. Reduced miscommunication and dropped follow-through by proactively tracking action items and closing the loop across stakeholders. Enabled progress on initiatives with no single decision-maker, by using communication to drive consensus.

Why this matters

This is a different kind of leadership than owning a budget or a program — it's leading through influence, not authority. Being the person who keeps a cross-functional team aligned, visible, and accountable is a skill leadership notices even when it doesn't show up on an org chart. It's also exactly the kind of scope that signals readiness for a role with more formal authority to match.

04

Dexcom — Stelo: Ongoing Channel Support Since Launch

Associate Marketing Manager, Global Market Access | Dexcom

Supporting the payor/channel side of Dexcom's first over-the-counter CGM since its 2024 launch — new territory for Dexcom, requiring a different access and education model than prescription CGMs.

My role

Ongoing production support and stakeholder coordination for payor/channel materials post-launch, adapting materials as Stelo scaled.

Context

Stelo launched August 2024 and surpassed $100 million in revenue in its first twelve months, generating $130 million in sales for the full 2025 year.

What this demonstrates

Sustained, adaptable channel marketing support beyond a single launch moment — iterating materials as a product scales and its market matures.

05

Drybar — Influencer & PR Strategy

Influencer Marketing & PR Manager, Drybar | Mar 2023 – Jun 2024

Owned influencer, social, and PR strategy for Drybar's product launches, starting with Final Call and continuing through subsequent releases — from creative development through content deployment. Managed a coordinator and an intern in support of this work.

Results

Campaigns averaged 80M+ impressions and a 3–5% increase in engagement rate. Managed 25+ influencers per month (macro, micro, nano) against quarterly budgets over $75K, plus external agency relationships for events like pop-ups, press dinners, and creator Q&As.

What this demonstrates

Full-funnel ownership of a marketing channel from strategy, to budget, vendor negotiation, team management, and measurement.

06

Flora — Content Strategy & Team Leadership

Content Marketing Manager | Feb 2022 – Mar 2023

Led content strategy across owned, earned, and paid channels for Flora and its portfolio brands, hiring and managing a team of 5 social media professionals. Drove a 100x increase in reach and 90x increase in engagement, growing 3,000+ followers in the first three months.

07

Match Group — Executive PR & Thought Leadership

Publicist, Match Group | Mar 2021 – Feb 2022

Served as PR lead for story development, thought leadership, and publicity campaigns across Match Group's executive team and portfolio brands (Tinder, Hinge, OkCupid, Plenty of Fish).

Results

Secured coverage in 250+ top-tier media publications, including the New York Times, Wall Street Journal, Bloomberg, and Forbes.

What this demonstrates

Ability to build executive visibility and media relationships at a top-tier level.

08

Match Group — Brand Refresh & Website (mtch.com)

Communications Coordinator, Match Group | Apr 2019 – Mar 2021

Spearheaded the project management of Match Group's new logo creation and website design (mtch.com) — the brand identity and site that still represents the company today.

Results

Contributed to increased brand awareness and website engagement following launch.

What this demonstrates

Ownership of a foundational brand asset - an infrastructure that's had lasting visibility for the company for 5+ years, not just a campaign with a defined end date.

09

Tinder — Swipe Night (2019)

Communications Coordinator, Match Group | Apr 2019 – Mar 2021

Swipe Night was Tinder's first interactive, choose-your-own-adventure video series, a first-of-its-kind format built into the app, airing live over four Sunday nights in October 2019. As Communications Coordinator, I was part of the PR team that led the campaign, planning and executing communications strategically supporting Tinder's objectives and managing correspondence with reporters, editors, and agencies covering the launch.

Results

The first rollout reached 15–20 million participating users, driving a 26% increase in matches and 12% increase in conversations. The campaign ranked in that year's World Creative Rankings and won multiple industry awards.

What this demonstrates

Early-career experience on the PR team that led one of the most awarded, highest-risk campaigns in the dating app category, under a live, time-boxed launch with no room for error.
