Our team

“Having co-founded my first social media consultancy in 2000 and worked in several high-growth tech companies, I’ve realised that the key to running a successful organisation is very simple: build a genuine team and give them a clear mission.”

Luke Brynley-Jones

Our mission at OST is crystal clear

To provide the highest quality social media expertise. We have created a highly skilled and experienced team that can deliver complex, large-scale, and global projects. I believe human relationships play a huge part in this.

I’m extremely proud of the positive, collaborative and supportive culture we’ve created at OST. Our awards and global portfolio may attract new business, but our high client retention rate is down to one thing:

our amazing team.
Managing Director

Luke Brynley-Jones

Luke is the founder and Managing Director of OST. It’s fair to say, he’s fanatical about getting B2B companies to use social media properly.

Luke was building social networks before most people knew what they were. In the late 90’s he built a string of support forums for people with niche health conditions. In 2003 he co-founded etribes.com, one of the UK’s first social networks. In 2007, he launched a mobile social network with a Dragon (from UK TV’s Dragon’s Den), which rapidly grew to half a million active users.

After hosting series of conferences across Europe and the US (an experience he later described as his “PHD in social media”), in 2013 Luke launched Our Social Times, the social media agency we know today as OST.

Over the past 12 years Luke has advised many of the world’s best known B2B brands on social media – often reworking or completely overhauling their strategies. His in-depth understanding of the LinkedIn algorithm and opportunities for organic growth on the platform enable OST to predict and deliver sustained growth for our clients.

A keen sportsman, Luke captains his village cricket team and regularly limps into the office after Monday-night football. He remains a stalwart fan of Ipswich Town FC, in spite of everything.

Client Experience Director

Stef Lait

Stef specialises in developing and executing digital strategies that deliver outstanding results for clients across industries such as tech, wellbeing and agriculture. She ensures clients are consistently delighted with the quality and effectiveness of their campaigns.

Stef plays a pivotal role in guiding the Client Services team and driving business success with a positive, results-driven approach.

Strategy Director

Helen Sharpe

Helen is the creative powerhouse behind our client's campaigns, leading strategy and storytelling with energy and empathy. With years of experience working with top brands, such as Marriott and Infosys, she’s passionate about proving that marketing is down to authenticity.

Helen’s knack for capturing attention (and hearts) extends beyond work, she's also a wedding photographer on the weekends. Whether crafting a campaign or snapping a special moment, Helen’s all about connection, creativity, and making an impact.

Operations Director

Jeremy Taylor

Hi I'm Jez, Ops Director at OST. My job is to keep all the cogs turning, which boils down to two things: productivity and profitability. I also have a background in Paid Social and regularly get involved in devising ad strategies.

Ops Directors are often seen as a Jack of all Trades, and that probably fits. I've done almost every role within the agency. However, what really makes me tick is problem-solving.

I'm all about the bigger picture. Whilst client teams prioritise servicing their clients, I'm free to step back and look at the trends and improvements we can make for the long-term.

From my time working at activity centres, I have all kinds of obscure qualifications. Amongst many others, I've been a qualified beach lifeguard, fencing coach, quadbike supervisor and archery instructor. Also, last season I finished in the top 1k globally in Fantasy Premier League (that's a big deal for anyone who knows about FPL).

Finance Manager

Aneta Fielding

I’m Aneta, OST’s go-to person for all things finance. Whether it’s managing payroll, handling client invoices, or keeping our books balanced, I make sure the numbers always add up. I also enjoy lending a hand with HR when needed.

With 20 years of experience in finance, my path here wasn’t exactly traditional. I started out as an au-pair, but along the way discovered a passion for numbers. It’s a journey that’s given me a fresh perspective and a can-do attitude that I bring to every challenge.

I love working with numbers and spreadsheets – there’s nothing quite like the clarity they bring, and they help me keep everything organised.

When I’m not at work, you’ll usually find me running, walking, or spending time with family and friends. I also have a habit of redecorating the house – my family never quite knows what colour the living room will be next!

Office Manager

Natasha Davison

I’m Natasha, OST’s Office Manager and unofficial wasp catcher, shelf installer and all-around go-to person. If it needs doing, I’m probably already on it. From keeping the office running smoothly to updating policies, offering I.T. and catering support and making sure everyone’s working in a happy, well-organised space.

My background is pretty varied, I've worked in everything from sales and party planning to running my own cake business for six years, which is something I’m really proud of. I’m at my best when I’m juggling multiple tasks at once and helping people out along the way. I’m also a trained mental health first aider, so supporting the team goes beyond just the practical stuff.

At work, I’m usually in the zone, but I’ll always pause for a chat about everyone’s holiday plans. Outside of work, you’ll most likely find me in a hardware store or garden centre, or working on a DIY project. My husband and I even built an outdoor kitchen from scratch so we could host Christmas for our 21 immediate family members.

Fun facts? I’m trained in permanent makeup tattooing, I’m learning to ride a motorcycle (wish me luck), and I can’t resist a bag of sweet chilli Kettle Chips. If you ever hear "Sure, I can do that" in a meeting, it’s probably me.

Senior Account Director

Georgia O'Keefe

Georgia is passionate about building strong relationships and delivering results that have real impact. With 13 years of experience in social media, she has worked with some of the world’s biggest brands, including Salesforce, gaining a reputation for her strategic thinking, organisation, and ability to bring calm to even the most fast-paced environments. She thrives on collaboration, ensuring every campaign benefits from diverse perspectives and expertise. A true team player, Georgia believes the best work comes from strong partnerships, whether she’s leading a project or offering support as the ultimate wing-woman.

Outside of work, Georgia has a deep love for musical theatre. Whether it’s the sweeping romance of Miss Saigon, the classic charm of Guys and Dolls, or the 00's fun of Mean Girls, there’s nothing quite like the magic of a great show. If she’s not at the theatre, she’s likely spending quality time with her fiancé and family, whom she adores. Her nieces and nephews are her absolute joy, and for Georgia, the best moments are the simple ones: game nights, uncontrollable laughter, and shared stories around the table.

Amongst the many things she'll talk about for hours, crime dramas and docuseries are in the mix. She’s watched just about every true crime series out there and loves diving into the details of each case. If there’s a mystery to solve, you can bet she’s already two steps ahead.

At her core, Georgia is about connection, whether in work, family, or her favorite pastimes. She’s the person you want on your team, in your corner, and sharing in life’s best (and most entertaining) moments.
Contrary to popular belief, Georgia is not currently selling a sofa on gumtree.

Senior Account Manager

Anna Foks

As a Senior Account Manager at OST, I’m responsible for the delivery of social media programmes across a wide range of B2B clients. I’m the main point of contact for all external communications – I am essentially email Barbie.

My day-to-day involves spinning many plates, collaborating closely with our talented delivery teams to ensure ideas are heard, strategies are sound, and campaigns run like clockwork. I’m a firm believer in the power of collaboration – the best ideas come from open, inclusive conversations, not just org charts.

I started out with a degree in English Language & Linguistics before heading to China to teach English. That experience ignited a love, borderline obsession, for tea, which led me into the world of FMCG brand-side marketing. With over a decade's experience, I’ve worked across a range of sectors, and in recent years made the switch to agency life – managing multi-client social media campaigns and driving performance from a more strategic level.

One of my proudest professional moments was launching a pop-up café in Harvey Nichols’ flagship store – an amazing project that gained coverage across digital and print media and allowed me to flex my creative execution muscles.

My working style is best described as relaxed but organised – a calm presence with a good colour-coded spreadsheet always to hand. My overactive mind means I thrive in fast-paced environments and always aim to bring clarity, calm and positivity to the teams and clients I work with.

Fun fact: I can touch my nose with my tongue. A niche skill, but a skill, nonetheless.

Walk-on song: Literally anything by Beyoncé

Meeting catchphrase: "Anymore for anymore?"

First song on the office playlist: "9 to 5" by Dolly Parton (to LT’s dismay, obviously)

Senior Account Manager

Jasmine Pitcairn

Jasmine is our Senior Account Manager, bringing over five years of experience in social media and influencer marketing. She specialises in helping brands find their potential through strategic organic and paid social campaigns. With a track record of managing successful projects for top B2B and B2C brands such as Salesforce, Tesco, and The Body Shop, Jasmine’s passion for social media drives her enthusiasm for continuous learning and delivering results. A true plate spinner, she thrives in fast-paced environments, juggling multiple campaigns while staying ahead of the latest social media trends.

Beyond her expertise in social media and influencer marketing, Jasmine plays a key role in shaping company culture at OST. As part of the Culture Committee, she organises initiatives that promote employee well-being, charity efforts, and team socials. In meetings, you’ll often hear her signature phrase "Ok, perfect!" delivered an octave higher than normal, like a human exclamation mark 😀

Outside of work, Jasmine is always planning her next sunny getaway, using TikTok as the ultimate source to find restaurant and activity recommendations. She’s currently on a mission to make running her full personality (jury’s still out on whether she loves it), and since a client trip to Nashville in 2024, she’s embraced the honky tonk lifestyle. If she had a walk-out song, you’re likely hear a classic from Shania Twain or Dolly Parton because nothing sets the tone quite like Man! I Feel Like a Woman or 9 to 5.

Senior Account Manager (US)

Joanna Stratmann

Joanna brings over 15 years of experience in marketing and relationship building to her role as Senior Account Manager at OST.

Based near New York, Joanna works with major brands to create, implement, and measure impactful cross-channel marketing strategies. With a passion for mission-driven organizations, Joanna combines data-driven insights with a commitment to creating meaningful outcomes.

Whether it's strong client relationships or analysing customer behaviour, her dedication to results and societal impact shines through in everything she does.

Creative Lead

Debbie Carr

I'm Debbie, OST’s Lead Creative, and I'm also a qualified copywriter. I lead our Creative team and oversee the development of content across major campaigns, with a strong focus on strategic thinking, storytelling and tone of voice. My day-to-day includes mentoring a brilliant group of Creatives and Community Managers, guiding everything from social media content and ad copy to long-form blogs, eBooks and influencer campaigns.

With a background in science (I studied Biological Anthropology and later Chemistry - yes, an odd combo), I bring an analytical approach to creative work. Before joining OST, I spent six years in sales and digital marketing for the scientific tech sector, which gave me a strong foundation in understanding complex products and audiences - especially in B2B. Since then, I’ve created content strategies and copy for brands across fintech, tech, marketing, science, agriculture, real estate, e-commerce, education, and more.

I love collaborating across teams, whether I’m working with Design on visuals, Sales and Marketing on pitch decks, or Client Services on full-scale creative campaigns. I'm passionate about producing work that’s not only beautifully written but truly aligned with the heart of a client’s brand.

And while creative storytelling is a big part of my day job, it’s also my passion outside of work. I’m a romantasy author, and my debut novel (ten years in the making) is being published in June 2025. I write strong complex heroines who don’t wait around to be rescued - something I like to think influences the way I approach creative leadership, too.

Content Manager

Michael Chubb

Hi there! My name is Michael and I am a member of your creative team at OST. As a Content Manager, I bring creative content and campaigns to life across social platforms. I write engaging copy, craft social content strategies, and manage the content creation process from concept to delivery.

My professional background as a generalist marketer comes together with my personal and educational background in music production giving me a unique perspective and blend of creative skills and practices. I graduated with Distinction from Falmouth University’s MA in Marketing & Digital Communications in 2023, where the topic of my dissertation focused on the unique power of sonic branding in advertising. Before OST, I built up a breadth of experience in marketing, campaign and events planning, brand management, copywriting and design, working across a range of platforms. I’m confident leading on everything from tone of voice development to campaign creation.

I’m a planner at heart and detail-oriented, which means you’ll often find me wearing my noise cancelling earphones to limit office distractions! I am, however, always up for a good brainstorm session or natter at the coffee machine. I get stuck-in wherever I’m needed, and you can often hear my name being called from all corners of the office when there’s an Excel spreadsheet or formula that requires fixing...

Outside of work, I produce electronic music and dabble in my other creative passions, such as graphic design and animation. After hours spent on computers both in and out of work, I enjoy other hobbies such as walking with my partner, cleaning and tinkering with cars and getting stuck into some DIY.

Community Manager

Kathryn Bezuidenhout

I’m Kathryn, OST’s Community Manager. Day-to-day, I focus on engaging, supporting, and delighting the online communities of our clients. That means keeping a close eye on social channels, staying in tune with the latest conversations in their industries, and responding quickly when needed. I particularly enjoy the Community Management we deliver as part of our LinkedIn Thought Leadership offering. This is a real chance to showcase our clients’ expertise and build genuine connections. I also run influencer marketing programmes for some amazing global brands.

Before joining OST, I graduated with a First-Class BA Hons in English Literature and Drama from the University of East Anglia (UEA), and started my career in PR. This foundation has been invaluable in the fast-paced, reactive world of Community Management and crisis comms. I’ve worked in agencies for years and got my start in digital marketing at a SaaS start-up.

At work, I’m a firm believer in the power of a morning chat at the coffee machine to set the day off right. I’m proudly South African and moved to the UK 13 years ago - this means you'll often hear me saying phrases such as "Ag, shame", "now now" and "hectic"!

In another life, I dreamed of becoming this generation’s Judi Dench. Theatre and film are very much my jam and, in my free time, you’ll often find me at the cinema.

Creative & Community Executive

Katie Collis

I'm Katie Collis, Creative and Community Executive. I spend my days managing online communities for global B2B brands across multiple social media platforms and managing influencer marketing programmes. As well as collaborating closely with our senior creatives to develop and execute social media campaigns. (And keeping the office young... kidding. Kind of.)

My background has always been rooted in marketing, with a particular interest for social media. I love how quickly the space evolves, and I enjoy finding creative ways to help brands show up meaningfully and staying relevant. Whether it’s brainstorming content ideas, jumping into comment threads or searching for the latest trend, I bring a calm and collected energy to everything I do.

Before OST, I built up experience across various social-focused roles, and I don’t see myself leaving the social scene anytime soon because there’s always something new to learn, test and get excited about!

Fun fact - As a child, I once imagined myself as an actress until stage fright suggested otherwise. I now prefer being behind the scenes, creating the content rather than being it. (Unless it’s my own Instagram, of course.)

Head of Design

Daniel Brand

Hi, I’m Dan, Head of Design at OST Marketing. I look after the visual side of things. I’ve been working in the design industry since I was 16, diving straight into my first role out of school and not stopping since.

I’ve got a passion for visual storytelling, especially through photography (landscapes are my thing). When I’m not behind a screen or a camera, I’m usually chasing after my two daughters, or our dog, who all think they run things!

Senior Designer

Tom Yallop

I’m Tom, Senior Designer here at OST. Working in a fast-paced social media environment means no two days look the same. Whether it’s animation, video editing, creative concepting, presentations or client calls, I’m involved in pretty much every corner of the design process. I work as part of a tight, collaborative team where ideas move quickly and visuals matter.

Before joining OST, I ran my own business, which gave me a solid grounding not just in design, but in the bigger picture: understanding what clients need, what makes a brand stand out, and how to make creative work really deliver. I like to think I bring positive energy and happy vibes to the studio.

Outside of work, you’ll usually find me chasing waves, carving through snow, or dancing until my shoes give up. But I would say I'm most content with a big cup of tea (or a cold beer), and a laugh with family and pals.
