Bret Taylor shared thisAnother week, another agent. Explorer is Sierra's agent-optimizing agent. Think of of it like ChatGPT deep research, but instead of doing research on the Internet, it's doing research over your customer conversations. Explorer is driving meaningful impact for so many of our customers already. “At ADT's scale of hundreds of thousands of conversations, manual QA is impossible. The deep research in Explorer has been a massive step forward for ADT’s Sierra Platform, allowing us to uncover hard to analyze performance vectors that were previously invisible. By combining Virtual Agent Performance with Customer Experience insights, we’ve moved beyond just identifying problems to strategically driving growth in both containment and customer experience.” - Matt Robbins, ADT “Explorer is transforming how we understand and optimize customer interactions. Our teams can ask plain‑English questions and quickly see what’s happening, where to focus, and what actions will have the biggest impact without digging through data. That faster access to insight helps us make better decisions. It’s a powerful step forward in making DIRECTV’s customer experience smarter, faster, and more data-driven at scale.” - Ryan Mann, DIRECTV

For complex agents with hundreds of journeys, that's a lot of work. With Ghostwriter, you can simply ask and it will tell you exactly what your agent is doing, and why. You can then prompt Ghostwriter to make any changes with complete confidence. Check out this demo to see it in action.

Bret Taylor shared thisI’m excited to announce that Sierra has acquired Opera Tech in Japan. Opera’s co-founders, Keita Morikawa and Kiyo (Kiyohito) Kunii, started the company with the simple idea that AI could help businesses deliver high-quality customer experiences at scale. We’re so excited to have them join us to lead Sierra in Japan. https://lnkd.in/gJvr5rvk

Bret Taylor shared thisToday, Sierra is releasing Ghostwriter, our agent for building agents. With Ghostwriter, you can create an AI agent for your customer experience — one that can chat, pick up the phone, speak dozens of languages, take action on your systems of record, and be protected with industry-leading guardrails — simply by having a conversation. No clicking, no forms, no menus. Codex and Claude Code have transformed how we build software, making it possible for software engineers to orchestrate and review the work rather than doing all the work themselves. We think the same transformation will happen for all software. Rather than every enterprise app having a web app for humans and an API for automation, every software platform’s UI will be an agent that can do the work on your behalf. I recorded a demo of my building and optimizing an agent with Ghostwriter so you can see how powerful and easy it is to use. It’s completely changed the way our early adopters build agents, and it’s changed the way I think about the software industry. Let me know what you think, and, if you’re interested in trying it out at your business, please reach out directly. You can check out the full blog post in the comments.

Bret Taylor shared thisI had a great discussion with Sam Violette from Nordstrom at the Shoptalk conference in Las Vegas. Nordstrom’s partnership with Sierra set a new standard for speed and quality. Nordstrom went live with Sierra in just five weeks, and scaled from 1% to 100% of calls in just a week and a half. Nora, Nordstrom’s AI agent, is such a delightful experience. As Sam put it, “As we started to see CSAT scores and surveys come back, it was less of a question about the risk to roll this out more broadly, but instead why would we hold this back from our customers.”

Bret Taylor shared thisLast fall, OpenAI announced its recapitalization, paving the way for the OpenAI Foundation to access significant resources. On behalf of the Board, I’m excited to share an update today on how the Foundation is starting to put that support to work – including our plans to spend at least $1B over the next year and the team we’re putting together. Our work is just beginning. We’ll have more updates to share in the coming weeks and months. https://lnkd.in/gU5TVE7v

Bret Taylor liked thisBret Taylor liked thisAfter 24 incredible years at Salesforce, I am stepping into an exciting new chapter with Sierra AI. It is impossible to put into words how much the last two decades at Salesforce have shaped me. I had a front row seat to something truly unreal - joining Salesforce when it was a ~$25M ARR pre-IPO startup and watching it grow into a $40B+ global powerhouse. Along the way, I learned what great leadership looks like, how to innovate at scale, and how to grow with purpose and values at the center. Making the journey even more meaningful were the opportunities to build and lead teams across industries and geographies, launch new products, and integrate acquisitions. Most recently, leading MuleSoft and Data Foundation were incredibly fulfilling chapters, shaped by the exceptional teams that made it all possible. More than anything, it always came down to the many brilliant and dedicated people I had the privilege of working with - the teams we built, the challenges we tackled, and the relationships forged through big goals, long hours, and shared ambition. I am especially grateful to Marc Benioff, Parker Harris, and so many others who made this experience truly life changing. To everyone at Salesforce - thank you, sincerely. Carrying those experiences forward, I could not be more excited to join Sierra as President of Field Operations. Sierra is redefining customer experience with AI agents, and I am honored to partner with Bret Taylor, Clay Bavor, and the entire Sierra team to help drive the next phase of growth. https://lnkd.in/gHrnp4inEric Eyken-Sluyters joins Sierra as President of Field OperationsEric Eyken-Sluyters joins Sierra as President of Field Operations

🚨NEW EPISODE: Recorded live at FUTURE TITANS 2026 - Jeff Perry of Carta sat down with the iconic Seth Levine, co-founder of Foundry. Seth has been in venture for 25 years, built Foundry from scratch as an emerging manager himself, and has backed about 50 emerging manager funds through his fund of funds. He has genuinely seen every side of this table. They went deep on building Foundry, why VCs are in the influence business, not the decision business, and why the concentration problem in venture is not only bad for LPs, but also for the innovation ecosystem overall. And why Seth's new book, Capital Evolution, is so important for the future of America. 🎧 Links to listen... Apple: https://lnkd.in/ehQUQ2EM Spotify: https://lnkd.in/eU4FExpg

Three years ago, we launched Wisdom Ventures with a clear intention to support founders building at the intersection of well-being, human connection, and transformative tech. Since then, we’ve made 37 investments from our oversubscribed "minimum viable" $10M Fund I, backing early-stage companies in physical and mental wellbeing, women’s health, ethical AI, and human connection-centered innovation. We’ve always known we are on to something—what we didn’t expect was how quickly the data would back it up. Recent industry benchmarks show that most 2022-vintage emerging funds are experiencing the usual J-curve dip. In contrast, Wisdom Ventures is showing strong early performance: 📈 Net IRR (internal rate of return): >10% 📊 MOIC (multiple on invested capital): ~2x* ⏰ Median investment age: 18 months 💥 ....and # of our companies have a diverse founder by gender, race, or sexual orientation: 75% As we get ready to make our 38th and final investment out of Fund I and start deploying out of our significantly larger Fund II (first close May 1st), we’re filled with gratitude—for our founders, our LPs, our early supporters, our early believers, and this growing movement toward a more conscious, connected future, fueled by innovation from the ❤️ *Based on most current reports **Not in photo: Our fantastic operating partner, Zoe Rogers #WisdomVentures #ImpactInvesting #ConsciousTech #Wellbeing #AIForGood #FutureOfWork #VentureCapital

Don't Build a Better Wheat Farm" - Why Defensibility Stakes Are Higher in Deep Tech Just published a new piece on my "Ignore the Confusion" blog, building on thoughtful insights from Eric Ver Ploeg at Tunitas Ventures about startup defensibility. Eric's core thesis: Too many startups pitch like wheat farmers - "huge TAM, slow incumbents, growing market, domain expertise" - but fail to think through long-term defensibility until it's too late. From a deep tech perspective, the stakes are even higher: ** Unlike software, deep tech founders must commit to defensibility strategies from day one - their funding depends on it ** Patent vs. trade secret decisions are often difficult to reverse and shape your entire competitive strategy ** Even "picks and shovels" providers (the tools that make industries more efficient) become commodities without proper moats The key insight that resonates: Defensibility can't be retrofitted. Whether you're building software or deep tech, your moat must be architected into the business model from the start. Thanks to Eric Ver Ploeg for sharing these insights on startup strategy and letting me build on his framework from a deep tech lens.

Talking to users and thoughtfully integrating their needs and wants was woven through everything we did at IDEO—threaded through every prototype and product decision. Reading my colleagues Joanne and Leo's latest work brought that to mind. They describe a future where research runs continuously, with AI agents recruiting participants and instantly surfacing insights. Synthetic personas, carefully trained on consumer signals, mirror human behavior closely enough to extend live studies and compress timelines from weeks to hours. Today user research mostly runs in fits and starts, prohibitively expensive and locked away in dedicated project cycles when it could be a constant companion, seamlessly integrated into the product development process. Joanne and Leo lay out the full vision here: https://lnkd.in/gEUBSG_J

Today I'm presenting to The Council Angels' latest cohort, focused on product leaders. They're on week 6 of our angel investing 101 curriculum. By now, it's becoming more clear to most of them whether angel investing is likely to be a hobby or an accelerator into to a future career in VC. My biggest advice to those who want a career in VC someday is to build their own proprietary flywheel for deal flow. It may start with angel communities and syndicates, but eventually putting in the work to build their own sourcing mechanism will make them very attractive candidates! I love to highlight these 4 who have masterfully executed this pole vault into VC: ⭐ Ruffin Mitchener: (TikTok → MALIAM) ⭐ Sri Varre (Lazy Girl Capital → Pivotal VC) ⭐ Zehra Naqvi (The Z List → Headline VC → founder of Lore) ⭐ Michelle F. (SF IRL on X → Headline VC) #angelinvesting #venturecapital #risingstars

Building a startup is hard. It is especially hard in a country like Nigeria, where the ecosystem is yet to mature, and there are still many challenges to navigate. It is confusing, lonely, and full of uncertain decisions. Founders, especially early-stage founders, need as much support as they can get. Not “inspire to perspire” posts, but practical support on hiring, operations, funding, customer research, and navigating the regulatory landscape. Too many founders are surrounded by noise, surface-level advice, and generic content that does not reflect their current realities. What they need is a community that understands exactly what they are going through and can offer context that is immediately useful. Sierra Collective exists to be that community. A space where founders learn from one another’s live experiences and shorten the painful trial and error that usually defines the early stages of building. At Sierra, we believe that the most valuable support comes from those who are active in the trenches, navigating the same obstacles. If you are an early-stage founder, you should join the Sierra Collective. You do not have to figure everything out alone. As the African proverb says, “If you want to go fast, go alone. If you want to go far, go together.” Join Sierra: https://lnkd.in/d-Nzmtkq

"So what exactly is a venture studio?" I'm not sure how many times I've had this conversation over the last few years. At least a few times / week. For aspiring venture builder - especially those in institutional settings, 'getting' the model - and understanding how it differs from others - is critical. So, we're starting at the beginning. On March 19, I'm sitting down with Matthew Burris for the first session of the The Venture Studio Forum's University Track Speaker Series. Matt is widely credited for helping to define the venture studio asset class - he co-authored the Venture Studio Index and built the Three-Role Framework that the industry uses to classify studios. He's spent more time researching what makes a studio a studio than anyone I know. If you're at a university, research institution, or economic development org trying to figure out whether a venture studio makes sense for you, this is where to start. Note, this event kicks off a five part-series we're running through the VSF, all focused on helping institutions understand and evaluate the model. Here's the full program: Mar 19: What Is a Venture Studio?

Thrilled to announce that Together Fund is investing in Sentra, alongside a16z speedrun! You track results in Jira. Decisions in Notion. Conversations in Slack. But the reasoning, the debates, trade-offs, and context behind why you chose A over B, disappears into what we call "Dark Matter." A decision made in March looks insane by July because no one remembers the constraints that made it smart. I lived this firsthand at Twitter scaling from 800 to 8,000 employees, and at Google while launching AI Overviews to billions at planet scale. The problem isn't process. Process is compensation for something deeper: organizational amnesia. An organization’s "Systems of Record" doesn’t solve this, they encode it. They store what happened, never why. That's why we are investing in Sentra. Sentra is the always-on collective memory that eliminates organizational amnesia by maintaining accurate context for all members and agents, functioning as an operational nervous system. It connects to every channel where work happens, meetings, Slack, email, code commits, docs, calendars, and treats them not as artifacts to search, but as living signals to synthesize. The fleeting and the permanent, unified into a memory that understands. The founding team is built for this: - Jae Gwan Park (CEO): Product-first founder, memory systems research at UofT and MIT - Ashwin Gopinath (CSO): Former MIT professor, created "Reflexion" (NeurIPS 2023), agents that learn from mistakes, 2x founder - Andrey Starenky (CTO): Early Vapi engineer, ex-IBM, built to process enterprise-scale data firehose Together is an operator-led fund. We invest in problems we've lived. This is one of them. Many congrats Jae, Ashwin and Andrey, we are so excited to partner with you!

2026 federal funding update for ecosystem builders A week ago I wrote about where federal innovation funding stands for 2026. Here's what's changed in 7 days: What's now signed into law: The Commerce, Justice, and Science bill passed the Senate 82-15 on January 15 and is headed to the president's desk. This locks in: NSF → $8.75 billion (with protection against disproportionate cuts to any directorate) → Regional Innovation Engines: Up to $200 million EDA → Tech Hubs: $41 million → Build to Scale: $50 million → MEP: $175 million What passed the House, awaiting Senate action: The Financial Services bill passed 341-79 on January 14, confirming: SBA → Entrepreneurial development: $330 million (Congress rejected the proposed cut to $150M) → Regional Innovation Clusters: $9M → Federal and State Technology Partnership (FAST): $9M → Growth Accelerator Fund Competition: $9M What's still in flux: Leaders just released a final bipartisan package for Defense, Homeland Security, Labor-HHS-Education, and Transportation-HUD. The House may vote this week, with the January 30, 2026 deadline approaching. SBIR/STTR authorization remains expired. No new solicitations until reauthorization—though there's been some movement here. There's also a bunch of new AI policy I need to dig into still. The bottom line hasn't changed: You cannot build a 10-year innovation ecosystem on annual appropriations battles. The regions that succeed are strengthening their partnership infrastructure now, and leveraging federal funding as a bonus to accelerate outcomes. See the full analysis: https://lnkd.in/euDxDVkZ

Investors (esp deep tech investors) generally think about things/bet on "layers": the application, the infrastructure, the model. I think that's becoming the wrong way to look at it? The real opportunity is in the feedback loop *between* the layers. A new social app creates demand for new hardware, which in turn demands a new kind of intelligence - I'm calling it "The Agency Loop". My latest newsletter explores this thesis through three signals: the "weaponized transgression" of Cluey, the AI-driven materials science in Nature, and the architectural critiques of Kenneth Stanley. Bet the loop, not the layer :) You can read the full analysis here: https://lnkd.in/ggdVGEda #vibecap #vibecapital #vc #deeptech #AI #cluely

Construction projects get delayed and rework is required because of discrepancies across construction documents, submittals, requests for information, design, and other plans. TwinKnowledge’s AI Agents absorb structured and unstructured project data, surfacing and preventing conflicts before the work begins.

I’m thrilled to announce defy.vc’s investment in Birches Health as part of their $20M combined Seed and Series A funding round, alongside incredible partners like AlleyCorp, General Catalyst, Will Ventures, and others. As someone deeply passionate about backing companies that tackle important problems for our society, I couldn’t be more excited about what Birches is building—a national virtual clinic dedicated to treating gambling addiction and related behavioral disorders like gaming, sex, porn, and internet addictions. What excites me most is Birches’ innovative health assurance model: proactive, accessible, and affordable care that’s evidence-based and delivered right at home. With the explosion of legal sports betting—think nearly $1.5 billion wagered on this year’s Super Bowl alone—we’re staring down a looming public health emergency. Traditional options like hotlines or generic therapy fall short for this high-acuity issue, but Birches changes that by offering specialized therapy from trained clinicians, multimodal treatment, and peer support, all covered by major insurers like United Healthcare, Cigna, Aetna, and Blue Cross Blue Shield. It’s available in all 50 states, breaking down geographical and financial barriers that have left so many without help. The impact is already profound: 96% of patients report an improved quality of life, and 94% give Birches a 5/5 rating. By partnering with state governments, payors, and policymakers, Birches is pushing gambling addiction into the spotlight of behavioral health conversations, where it’s been neglected for too long—often leading to shame, worsened outcomes, and higher suicidality risks. This funding will supercharge their growth: expanding the provider network, boosting clinical excellence, scaling infrastructure, and deepening insurance and state partnerships to meet surging demand. Very excited to partner with Elliott Rapaport and the entire Birches team!

Founders Co-op • 4K followers
While there has never been a more exciting time to be a founder building dev tooling or next-gen infra, it has also never been less investable at seed/pre-seed. I'm either really missing something or a lot of my peers are lost. As someone who has not just written, but also SHIPPED, about 75k lines of code in the past 6 months I can tell you that the evolution of how to build products has changed as much in the past year as it did in the entirety of 2007-2017. The complete rise and fail of frameworks, platforms, methodologies, etc... paved over and forgotten... that is of course except for the 1 company that gets a 1000x return from a wildly overvalued hyper-scaler or drunken growth stage investor obsessed with compounding at scale. Imagine a world where any seed investor in trends like Openstack, Hadoop, PaaS, etc all took a full loss on their investment. That's what we're looking at right now. I personally know of over a dozen well-funded seed-stage companies building in these spaces, with years of runway, scrambling to get acquired for a return of capital + several million personally while they're still relevant. If you're not seeing this unfold in front of you, you either aren't paying attention or you're satisfied playing the lottery instead of investing.
