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!

I’m thrilled to officially announce our $3M seed investment in Propel People, a company we built inside the 1848 Ventures studio to tackle one of the biggest challenges facing the #construction industry today: the skilled #labor shortage. For small and medium-sized contractors, hiring isn't just a challenge. It's the number one threat to their growth, profitability, and safety. With 94% of contractors struggling to find qualified workers, it’s clear that traditional hiring methods aren't built for the trades. That’s why we built Propel People. It’s a mobile-first, AI-powered hiring platform designed for how construction actually works: in the field. By leveraging smart candidate ranking, instant #SMS-based screening, and a fully #bilingual interface, Propel helps contractors build great crews faster and more efficiently. I’m also thrilled to formally announce that industry veteran Dexter Bachelder is at the helm as CEO. Having worked with Dexter and the team over the last few months, we've already seen the impact of his leadership. His 25 years of experience scaling construction tech companies will be instrumental as Propel People enters this initial stage of growth. This investment reinforces our core thesis at 1848 Ventures: building AI-native companies that solve fundamental pain points for the #SMBs that form the backbone of our economy. A huge congratulations to Dexter and the entire Propel People team on this milestone. We are incredibly proud to partner with you to support the people who build our world.

This a seductive idea; that organization's context fragments, decision logic gets lost, and an organization is prone to tackle collective amnesia. BUT this comes with a lot of caveats!! - MONOCULTURE: When one system becomes the authoritative interpreter of "why things are the way they are", it will collapse pluralism. An organization actually benefits from various "contested memories". An engineer and sales guy remember different things from a discussion and that helps. Employees can stop arguing with the system not because its correct but its "coherent". - OBSERVER's EFFECT: When people know that the reasoning within systems is being captured, they will change what gets recorded. The negotiations will become "safer" and will contaminate raw signals. - CENTRALIZATION: Interpretation gets centralized upwards. It may appear leadership or executives are gaining synthesis and becoming closer to the ground. But there is no comparison to living through the frictions, not even eclectic summaries. LEADERSHIP MUSCLE NEEDS TO PRACTICE LIVING THROUGH FRICTION OTHERWISE IT WILL TURN SENILE. - BIAS AMPLIFICATION: Model's inbuilt biases can combine with company's cultural quirks resulting in misinterpretations and distortions, worse they get reinforced over time. System will learn how the company thinks and then will optimize for continuity. AMNESIA IS SOMETIME A FEATURE. - SEMANTIC TRUTHS: Unlike objective truths this system will play on subjectivity and will build "causal" relationships that are based on semantics. This over time can form mythical decision norms with no external validity. The real question isn't "CAN IT BE BUILT?". Of course it can be. But "HOW IT SHOULD BE POSITIONSED". #llms #leadership #ai

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.

Summary: The venture firm CRV has raised $750 million for its 20th flagship fund, which will focus on investing in early-stage startups, particularly in the consumer and devtools sectors. Key takeaways: CRV's new fund is smaller than their previous one, but still received strong demand from investors. The firm has a history of successful investments, with 80 startups eventually going public since its founding in 1970. CRV is shifting its focus away from late-stage rounds, citing lower overall returns, and towards seed and Series A investments. Counter arguments: Some may argue that CRV's decision to not raise another late-stage fund could limit its opportunities for growth in the future. The success of the new fund will ultimately depend on the performance of the startups it invests in, which can be unpredictable in the volatile tech industry. #venturecapital #fundraising #startups https://lnkd.in/g8d-N9jX

At Vibe Capital, we believe the venture landscape is bifurcating. The reason is simple: reality is full of drunk cats. "Drunk Cats" are the emergent, second-order effects that arise from simple rules. They can tank a product, entire system, or an entire country. The ability to see -and master - these drunk cats reveals the true split in startups today. It is no longer between software and hardware, but between "impressionistic" founders who map the world as it is, and "mechanistic" founders who can reverse-engineer reality from first principles. My latest Dave's Quick Hits newsletter provides the playbook for identifying and funding these mechanistic architects. It is about a fundamental shift from describing effects to mastering cause. I break down the three core stages of the Mechanistic Playbook: 1. See the System: Identifying the hidden rules and emergent flaws in any complex system, from software to biology. 2. Debug the System: Using technology to patch the legacy "bugs" of a previous industrial paradigm. 3. Architect a New System: Building with true primitives, like DNA, to program matter itself. The next trillion-dollar companies won't be built by operators chasing surface-level trends. They'll be built by system-thinkers who can see, debug, and architect reality’s source code.

Midi Health just raised a $100M Series D and became the first menopause unicorn. This marks Actions Capital (fka K50 Ventures)'s ninth unicorn on the platform AND first investment for the Actions Growth Co-investment platform! We first met Joanna Strober in 2021 when we invested in the pre-seed, thanks to an intro from portfolio founder, Sarah Adler, PsyD (thanks Sarah!!). To me, the problem was staggering: 45 million women in the U.S. seeking care for menopause symptoms and not getting treatment, only 500 certified menopause providers in the entire country, 97% of midlife women without an OB/GYN, and an entire healthcare system that essentially told women to “tough it out”. Joanna had lived this problem herself, spending over a year searching for care, driving an hour to see a specialist, paying out of pocket, etc., and asked the question that would become Midi: Why isn't expert care for women at midlife easily accessible and covered by insurance? What started as a virtual care clinic has become the platform redefining how midlife women access healthcare in this country: • 25,000+ women receiving care every week. • Insurance-covered expert care in all 50 states. • Fortune 100 employers offering Midi as a health benefit. • Partnerships with major health systems and benefits providers nationwide. • Care that has expanded well beyond menopause into the full spectrum of midlife women's health. This $100M Series D round at $1B valuation was led by Goodwater Capital with Serena Ventures, Foresite Capital, and earlier investors including GV, Emerson Collective, SemperVirens, McKesson Ventures, AVP, and Felicis participating. Congrats to Joanna Strober, Sharon Meers, Jill Herzig, Kathleen Jordan, MD, Mindy Goldman, and the entire Midi Health team. You're no longer proving a concept. You're scaling a healthcare organization that women rely on every day. Let’s cook!
