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!

Resale is one of the fastest-growing sectors in commerce, but scaling it is complex. Product intake, authentication, pricing, and listing are still largely manual, slowing growth and limiting margins for retailers entering the resale space. HAMMOQ Inc. solves this by automating resale operations. Their AI-powered platform handles product listing, content generation, pricing optimization, and marketplace management, enabling retailers and recommerce platforms to scale sustainably and profitably. At Silicon Road Ventures, we invested in Hammoq because they’re powering the operational backbone of the circular economy, making sustainability not just a value, but a viable business model. 🔗 https://lnkd.in/gyeuJgu9 Discover the exceptional founders who are forging the future of commerce: https://lnkd.in/gyikTJ3c #PortfolioCompany #CircularEconomy #AI #RetailTech #Automation #Recommerce

Today Isembard announced a $50m Series A fundraise led by Union Square Ventures, less than a year after Notion Capital led their Seed round. 💥This is a company right at the intersection of AI & supply chain sovereignty & they’re exceeding even our most optimistic expectations. By the end of the year they will have 25 factories across the UK, US, Germany, France & Ukraine. 💥Isembard is rapidly scaling its network of AI-first factories for precision manufacturing at the same time as market demand is accelerating. Macro forces (reshoring, rising defence spend, concentration risk in Asia, and the growth of neo-primes) are structurally increasing demand for fast, local, flexible manufacturing that the current industry is unable to deliver on. 💥The innovation is in the way the company builds and franchises factories as a product with tightly integrated units of machines, software, robotics, & process intelligence that turn design files into certified components with speed & reliability. 💥Their AI software platform, MasonOS, connects all sites into a single operating system, replacing fragmented shops with standardised, high-performance industrial nodes & enabling real-time quoting, predictable delivery, & low defect rates. By owning the full production stack, Isembard delivers premium manufacturing performance with the scalability & flexibility of a software platform. 💥We are at the top of the AI hype cycle and there are understandable concerns about the ROI on the vast sums of money being invested into this new super-cycle. But, the ROI for Isembard is both clear and compelling. They will deliver components 10x faster and at 50% of the cost of current suppliers. They will also build a de-centralised, global network of factories to meet the growing demand for national or regional sovereignty. 💥This is a company with a clear vision to disrupt a massive, fragmented $1.8tn component manufacturing market. Today marks another huge stride towards that vision. And they are only just getting started. We’re thrilled to be on this journey with Alexander Fitzgerald & the team & we’re also excited to welcome Rebecca Kaden & USV into the investor base.

Voice is a super interesting modality right now - maybe the first modality we're seeing move to open source models across a number of scale ups / enterprises. Reliability concerns, high costs, and open source model performance are pushing engineers to do their own fine tuning vs. relying on third-party vendors of proprietary models. Many of these orgs have already been collecting their own first-party data and now with third-party vendors like Extrian, David AI, etc they can train really high quality models. RL has been insanely hyped, but it's been unclear how long it will take scale ups and enterprises to actually lean in. Voice AI might be hitting that inflection point faster than expected.

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.

"Build the event you wish existed" That's what we at Monadical did last week at #NYTW. We wanted an AI Engineers discussion for Engineers. There's always a lot of events out there for VCs to network, or for startups to learn about G2M, but very little on lessons learned from actual engineers in the field. So that's the event we hosted. Big thank yous to our awesome panel, Roy Pereira, Ben Cohen and Corey J. Gallon. Here's the key takeaways and the AI tools we're using. 🚀 All three panelists independently called AI Agents the most transformative LLM application they’ve used. They specifically called out Claude 3.5 Sonnet for its accuracy and reliability. 🪨 We dug into how LLMs are “jagged”, not general. They can be shockingly good at some tasks and completely fail at others. Everyone agreed: good evaluations are critical (and hard.) 🧪 Corey noted how public benchmarks and reality are two different things. Most public evals are saturated or gamed. ♊ Ben emphasized that AI projects are actually two projects: building the tool and building the evaluation process. 🧱 We explored how falling dev costs may impact startup defensibility and labor demand. Roy shared that founders are already shifting strategies in response. ⚒️ In a world of daily AI launches, the panel discussed how they decide what’s worth attention, and what’s just noise. They called out tools like Goose, Aider, Claude Code, and Monadical’s own Cubbi, which helps run agentic workflows safely in dev environments. (links in the comments). CTA: What would you want to hear in an AI Applied Engineering talk you attended?

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.

Most VCs talk about sourcing. Nnamdi Okike built a software platform to do it with precision—and it’s helped 645 Ventures find and lead some of the best under-the-radar startups of the last decade. I had the pleasure of sitting down with Nnamdi, Co-Founder and Managing Partner at 645 Ventures, to talk about his journey from Insight Partners to building one of the most methodical early-stage firms in the game. We cover how Nnamdi sourced Facebook in 2004, what he learned from Insight’s outbound model, why most databases fall short, and how 645 uses frameworks like “founder paradigms” to assess quality where others see risk. We also dive into the firm's contrarian bets on companies like Resident, Panther, and RentSpree, how to win in “well-covered” categories, and why many of the best opportunities are where consensus says not to look. The link to Episode 486 is in the comment section below.
