Pinterest is a visual discovery and bookmarking platform where users save ideas as pins on themed boards. People browse and search for ideas across topics like recipes, home decor, and fashion, then save or share pins to organize their interests. The product works through a feed and search results that show relevant pins, with tools for creating, organizing, and sharing boards. It earns revenue mainly from advertising—promoted pins shown in feeds and search results—and affiliate marketing, earning commissions when traffic leads to retailers. The platform differentiates itself with its visual discovery engine, focus on saving and organizing inspiration, and its advertising and affiliate ecosystem that targets users based on their interests. Pinterest’s goal is to help people discover ideas they love and turn that inspiration into action by connecting users with content creators and businesses.

Pinterest beats revenue and user targets but shares fall 8% on slowing growth outlook

Pinterest reported strong second-quarter results but shares fell over 8% after hours on slower growth guidance. Revenue rose 18% year-on-year to $1.18 billion, beating expectations of $1.15 billion. Adjusted earnings of 43 cents per share exceeded the 36-cent forecast. Monthly active users reached a record 640 million, up 11%, with Gen Z comprising over half the user base. However, third-quarter guidance of $1.19 billion to $1.21 billion implies growth of 13% to 15%, down from 18%. Chief executive Bill Ready revealed Pinterest builds small, task-specific AI models and uses open-weight models rather than expensive proprietary systems, achieving costs under 8% of comparable closed models. The company raised its full-year adjusted EBITDA margin target to roughly 30% and generated $270 million in free cash flow.

Pinterest shares fall 7% despite beating Q2 estimates with $1.18B revenue on disappointing Q3 guidance

Pinterest reported second-quarter results exceeding expectations but shares fell 7% after-hours on disappointing third-quarter guidance. The social media platform posted revenue of $1.18 billion, up 18% year-on-year, beating the $1.15 billion consensus. Adjusted earnings per share reached $0.43, surpassing estimates of $0.36. However, third-quarter revenue guidance of $1.19 billion to $1.21 billion disappointed investors despite meeting analyst estimates at the midpoint. Global monthly active users hit a record 640 million, up 11% year-on-year, marking the 11th consecutive quarter of double-digit user growth. Adjusted EBITDA rose 24% to $311 million. CEO Bill Ready attributed the momentum to AI integration. The company completed over $2 billion in share repurchases year-to-date at an average price of $18.17.

Impact Level Use this briefing to decide whether your team needs an immediate workflow, policy, or reporting change. Key Stat / Trigger No single quantitative trigger surfaced in this report. Focus on the operational implication, not just the headline. Relevant For Brand Sellers Agencies Full coverage. Pinterest have moved to their new offices on Great Titchfield Street, London, just off the vibrant Oxford Street and in the heart of the area of London set for pedestrianisation. And their offices are massive... almost 30,000 square feet and every inch has been decked out in the Pinterest style Marketplacebeta has come to love with the types of beautiful accessories that you probably have Pinned in collections on your boards. The future of retail isn't online or offline, it's both. People increasingly discover what they want before they walk into a store, and that's exactly what Pinterest is built for - Marketplacebeta help close the gap between inspiration and action. That's why Marketplacebeta is so excited to open its new London home on Oxford Circus, one of the world's most iconic shopping destinations. Retail is entering a new era where AI, visual discovery, and physical stores blend seamlessly. As a 'digital shop window,' Marketplacebeta help partners - from London's top flagships found at Oxford Circus to high streets everywhere - turn inspiration into real sales. - Greg Owens, Vice President of International at Pinterest Now it is always lovely to be invited to an office opening, but with tech companies it's normally a somewhat staid event with a few speeches, drinks and canapes. Not so with Pinterest, they prefer to do things that you'd actually want to do in real life so they didn't hold back. A cook-along with Jamie Oliver, have a manicure, and how about a portrait studio where once you've had your photos taken you can decorate and customise to your hearts content with stickers, beads, papers and ribbons and until you're ready to finally frame your photos to take home as a keepsake. But first of course there were some speeches and they were mercifully short... but that's the key message that Caroline Orange-Northey spelled out - the most meaningful thing you can find online is a reason to go offline... and so no one had time to be on their phones, they were all too busy having fun and living life for the evening. Following Caroline, the Mayor of London, Sadiq Khan, welcomed Pinterest to their new offices. This is a big deal for him as Pinterest now have some of the biggest offices in the Oxford Street area. But Sadiq couldn't resist revealing that he's a fan of Jamie Oliver and was looking enviously at the tables set with ingredients for the cook along that was about to follow. The opening of Pinterest's new UK office is another vote of confidence in London, which speaks to the extraordinary optimism in its booming tech sector, and I'm determined to keep this momentum going. I'm particularly pleased to have Pinterest setting up shop in Oxford Circus, where its work to transform Oxford Street will mean they can play a part in revitalising the beating heart of Britain's retail economy. I've spoken a lot about the need to reimagine online as a gateway to a richer, happier offline life, not a replacement for it - which is just what I see Pinterest doing, so I'm delighted that London is the place they've chosen to do that. I'm committed to supporting innovative businesses like Pinterest to grow and thrive as Marketplacebeta continue building a better, more prosperous London for everyone. - The Mayor of London, Sadiq Khan So, Jamie, restauranteur and celebrity chef, what's the deal with him and Pinterest? Well Jamie wants to get people cooking and so he's partnered with Pinterest to release a summer recipe collection featuring 290 recipes, including 10 created exclusively for the visual search platform. And Jamie's aim is aligned with Pinterest goal with the obvious reason to go offline is to get into the kitchen and cook! And... if you're interested, thankfully the cooking for the evening was Pavlova, so Marketplacebeta were soon busily whipping cream, adding yoghurt, and then decorating with tons of fruit, grains, coconut flakes and finishing off with edible flower decorations. Funniest part of the evening... Jamie repeatedly leaning over his whipped cream bowl and getting it all down the front of his shirt... even the celebrity chefs are human when they're having fun! Huge congratulations to all the team at Pinterest on their new offices... if you get a chance to visit you might not be cooking up a storm, but they're full of inspiration and a very happy place to be. In the mean time, get onto Pinterest but not for too long... you just have to find Jamie Oliver's exclusive recipes and you'll have found a reason to go offline!

Why Tamara Hinckley is building a better playbook for working mothers.

Why Tamara Hinckley is building a better playbook for working mothers. For Tamara Hinckley, the road to motherhood wasn't simple. After navigating infertility, welcoming her daughter brought immense joy and gratitude. But maternity leave also brought something she hadn't expected: a destabilizing loss of identity. Hoping to feel more like herself again, Tamara returned to work early. Mostly on her own, she learned how to juggle the demands of home and career, eventually doing it so well that she was promoted to Director of Product at Pinterest while seven months pregnant with her second daughter. But returning after her second maternity leave was different. Between postpartum depression, a bigger leadership role, and the loneliness of often being the only mother in the room, Tamara found herself wondering - for the first time in her career - if she should quit. As the systems that once helped her succeed began to break down, Tamara went looking for a better playbook. What she discovered was that the women who seemed to be thriving weren't doing it all. They were operating differently, with clearer priorities, stronger support systems, and a more intentional approach to work, motherhood, and leadership. That realization inspired Tamara to leave Pinterest and start Momentum Rising, where she now helps senior women redesign how they lead and live during early motherhood. Through her curated community, she empowers high-achieving moms to keep building ambitious careers without sacrificing the lives they want to be present for. What are some of the most meaningful impacts your business has had so far? Women often come to me wondering if they've lost their ambition and leave making some of the boldest career moves of their lives. Throughout my career, I've worked with dozens of women who were convinced they needed to step back, only to realize they still wanted to pursue their ambitions and just needed a more sustainable way of operating. One burned out client, for example, was considering taking a career break until she realized she actually wanted work that felt more energizing. Ultimately, she left her company to join OpenAI. Another client - who also happened to be a new mom of twins - stopped doubting herself and stepped into a senior leadership role at a startup. A third came in exhausted and convinced she needed to scale back, only to realize she needed better systems, not less ambition. She went for the C-suite promotion she knew she deserved - and got it! The transformation is rarely about becoming more productive, but about rebuilding confidence, clarity, and a way of operating that actually works for this season of life. Again and again, I see women stop questioning whether they still "have what it takes" and start leading with far more conviction and self-trust. When more mothers rise into positions of leadership, workplaces, policies, and expectations begin to change, too. As a mother of two daughters, that mission is deeply personal to me. It's bigger than any individual client. Have you ever felt like you're "different?" If yes, in what ways has this contributed to your journey as an entrepreneur? When I was seven years old and didn't know a word of English, my family moved from Ukraine to the United States. Growing up as an immigrant, I spent years feeling like an outsider and desperately wanting to belong. That followed me throughout my career as I worked in male-dominated industries on Wall Street and later in Silicon Valley. I know what it costs to feel like the only one: the self-doubt, the constant second-guessing, and the pressure to prove yourself over and over again. As the only woman in the room, I learned how to adapt, earn credibility, and succeed in spaces that were not designed with me in mind. When I became a mother, I found myself alone in rooms full of people who did not share my experience for the third time in my life. My managers were all men, and I had very few peers who were also mothers with young children. Momentum Rising exists because I wanted to build the community and support I never had. Ambitious mothers shouldn't have to figure it out alone. What's been the hardest and most rewarding part of your entrepreneurial journey? The hardest part of building Momentum Rising has been starting over - not from zero, because I bring 15 years of experience with me, but from a place where all the old markers of success disappeared. When I worked at Pinterest, success was easy to measure. I had a big title, a large team, clear goals, and constant external validation that I was doing well. But entrepreneurship is completely different. No one tells you if you are on track, and there is no promotion, performance review, or company brand signaling that you are succeeding. I'd spent years building a career at places people instantly recognized, and learning to stand behind something that's still growing has required a much deeper level of confidence than I expected. The most rewarding part of this journey, though, has been creating something that makes women feel seen in a stage of life where so many feel isolated and ashamed of struggling. I feel so proud when I hear women say things like, "I'm not doing it wrong; this is just hard" or "I finally have a path forward instead of feeling stuck in limbo." Working with more than 70 women over the last year, I've realized the most meaningful part of this work is helping ambitious mothers feel less alone in a season where so many silently believe they are failing. Has your definition of success evolved throughout your journey as a founder? For most of my life, success meant achievement: getting into the right schools, being promoted, and proving I could advance in highly competitive environments. Growing up as an immigrant with everything to prove, external validation defined me. Motherhood changed that. After becoming a mother, I could no longer optimize for work at the expense of everything else. For the first time, I started asking different questions: What kind of life am I actually trying to build? What do I want my daughters to see when they think about ambition? What does success look like if it includes my family, health, energy, and relationships... not just my career? What surprised me most is that letting go of the old definition of success has made me feel more ambitious, not less. My ambition is no longer about proving myself. It's about building something that matters deeply while also having strong relationships, a grounded family life, and the ability to actually enjoy the life I am creating. Have you discovered any underappreciated leadership traits or misconceptions around leadership? One of the biggest misconceptions I see is that motherhood reduces ambition. In reality, motherhood often exposes how unsustainable many of its systems already were. For decades, professional success has largely been built around an ideal worker model: someone with unlimited availability, very few caregiving responsibilities, and the ability to prioritize work above almost everything else. Even in modern dual-career households, women still carry a disproportionate amount of the invisible labor at home, which means many mothers are effectively managing two full-time jobs at once. Many women mistake the exhaustion that comes from that reality for personal failure. They assume they became less capable, less driven, or less ambitious after having children. But in most cases, the ambition is still fully there. What breaks is the system underneath it. Motherhood forces Dreamers & Doers to confront questions Dreamers & Doers could previously avoid: What am I optimizing for right now? Can I keep working this way for another five years? What kind of career and life can I actually sustain long term? After taking this time to reflect, many women become stronger leaders. They develop sharper judgment, clearer priorities, and a much deeper understanding of people, tradeoffs, and constraints. Especially as the pace of work accelerates with AI, I believe the future of leadership is not about working more. It is about building ways of working and leading that are both high-performing and sustainable in the realities of modern life. What's next for you and your company? In the near term, I'm scaling my flagship group coaching program and building the kind of community where ambitious mothers feel deeply supported, understood, and less alone while navigating early motherhood and leadership. But the bigger work is changing what women believe is possible when motherhood and ambition collide: helping them make decisions from clarity instead of fear, redesign their lives and support systems more intentionally, and pursue ambitious careers in ways that actually feel sustainable. At the same time, AI is rapidly reshaping the tech industry and new power structures are forming in real time. Senior women - already stretched thin and carrying a disproportionate share of the invisible labor at home - are at real risk of stepping back during one of the most consequential shifts in modern work. My work is about ensuring the women who do want to lead have the systems, community, and belief in themselves to keep rising and shaping the future of leadership from inside the room.
