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!

Project Vend reads less like a capability story and more like a governability story. Phase two improved because institutional scaffolding (tools, procedures, role separation) reduced predictable judgment failures—persuasion, compliance blind spots, boundary confusion, values drift. The board-level question isn’t “can an agent run a business?” but “what governance primitives must exist before we delegate authority.” Until incentives, escalation rights, and refusal boundaries are structurally enforced—not merely prompted—agents remain high-performing managers, not autonomous executives.

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

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

What do creative technologists build? At Baukunst, we’ve spent the last few years answering that question in real time. We are a collective of builders — operators, designers, engineers, and investors — committed to advancing the art of building at the frontiers of technology and design. We lead pre-seed rounds with conviction, often as the first institutional capital a founder takes, and we invest deeply in the messy, magical early days of company creation. This deck is the portfolio behind that philosophy, or rather that portfolio that has grown up out of it. We have chosen to champion these companies, and they chosen to co-create with us. These are companies built by creative technologists, founders who think in systems, design for real people, and push beyond the familiar.
