It is a layer that can remember goals, route work, and turn context into action across tools. - Summary: The next step in personal software is a shift from app-first workflows toward intent-first workflows. - Uncertain about: How much autonomy people will actually trust in high-stakes work without clear controls and audit trails. - Would change mind if: If users consistently prefer narrow app features over cross-tool delegation even after reliability improves. - Building because: Products should help people move from intention to useful output without losing context in the middle. - Evidence: - People already use AI as a thinking partner before choosing a tool. - Knowledge work has too many handoffs between search, writing, scheduling, analysis, and execution. - The bottleneck is increasingly context design, trust, and workflow fit rather than model access alone. ### Search becomes an answer and action interface - Slug: search-becomes-an-answer-and-action-interface - Status: active - Confidence: medium - Claim: Search is moving from finding pages to assembling context, producing answers, and routing the next action. - Summary: The best search products will combine retrieval, synthesis, memory, verification, and workflows. - Uncertain about: Which interfaces will earn enough trust for complex decisions: search boxes, browsers, agents, or embedded workflows. - Would change mind if: If citation-rich AI search fails to improve trust or task completion for mainstream users. - Building because: Search tools should make source-backed decisions easier, faster, and more inspectable. - Evidence: - AI search behavior is teaching users to expect synthesis, not only blue links. - Credibility depends on source visibility, citations, and user-controlled verification. - A good result increasingly includes what to do next, not only what to read. ### Personal sites become identity infrastructure - Slug: personal-sites-as-identity-infrastructure - Status: active - Confidence: high - Claim: A serious personal site should be more than a portfolio. It should be a source of truth that humans, search engines, and agents can cite. - Summary: Owned domains can outlast social feeds and make a person's work legible across contexts. - Uncertain about: Which agent-facing conventions will become durable standards versus useful-but-optional affordances. - Would change mind if: If major discovery systems stop rewarding clear, crawlable, source-backed owned web content. - Building because: This website should be the canonical identity graph for Jack Lau's work, writing, tools, and public context. - Evidence: - Social profiles fragment identity and push visitors into platform-specific context. - Crawlable pages, feeds, structured data, and machine-readable summaries give work durable surfaces. - Future agents need canonical contact, citation, and routing information from owned sources. ## Work Chapters ### Founder-led AI product work - Period: Now - Role: Founder / Builder - Location: Remote - Summary: Building practical AI products and a public archive around search, agents, tools, writing, and learning. - Outcomes: - Turning personal context into an owned-domain identity graph. - Designing tool and writing systems that can be extended through Sanity. - Building around AI search, agent workflows, and founder-led product loops. - Skills: AI products, Search, Agents, Next.js, Sanity, GTM - Links: https://www.thejacklau.com/projects, https://www.thejacklau.com/ideas, https://www.thejacklau.com/tools ### Searcle AI and startup experiments - Period: Founder path - Role: Founder - Location: Public web - Summary: Exploring Google plus AI search, build-in-public workflows, events, and early product discovery. - Outcomes: - Shaped a clear thesis around source-backed AI search. - Built public context through events, writing, and social channels. - Learned from the gap between interesting demos and useful repeated workflows. - Skills: Product discovery, AI search, Community, Founder sales - Links: https://www.thejacklau.com/projects, https://www.thejacklau.com/writing ### Bridgewater and IMC - Period: Quant chapter - Role: Quant / markets experience - Location: Professional experience - Summary: A markets foundation that shaped systems thinking, decision quality, feedback loops, and comfort with uncertainty. - Outcomes: - Built a mental model for decisions under uncertainty. - Developed taste for rigorous thinking and fast feedback. - Carried market-structure intuition into startup and AI product work. - Skills: Markets, Research, Decision systems, Quant thinking - Links: https://www.linkedin.com/in/jacktlau/ ### University of Ottawa - Period: Foundation - Role: Finance to computer science - Location: Ottawa - Summary: An interdisciplinary base across finance, computer science, mathematics, competitions, and founder communities. - Outcomes: - Built the bridge from finance into software and AI. - Competed in trading and investment competitions. - Passed CFA Level I and continued toward a builder path. - Skills: Finance, Computer science, Mathematics, Competitions - Links: https://www.linkedin.com/in/jacktlau/ ## Built Projects ### Searcle AI - Slug: searcle-ai - Status: active - Type: AI search product - One-line summary: A Google plus AI search direction focused on source-backed answers. - Problem: People want faster answers but still need credible sources, context, and a clear path to verification. - Audience: Builders, researchers, operators, and search-heavy knowledge workers. - Role: Founder - Stack: AI search, Retrieval, Product discovery, Founder-led GTM - Learned: The hard part is not producing a fluent answer. It is making the answer trustworthy, inspectable, and useful enough to repeat. - Links: https://www.linkedin.com/in/jacktlau/ - Related thesis: search-becomes-an-answer-and-action-interface ### Jack Lau identity graph - Slug: jack-lau-identity-graph - Status: active - Type: Personal site infrastructure - One-line summary: This website as a public identity graph, research archive, and proof-of-work index. - Problem: Social profiles and resumes are too flat to explain a person's beliefs, work, learning, and context. - Audience: Humans, search engines, AI agents, collaborators, investors, and future readers. - Role: Owner / Editor / Builder - Stack: Next.js, Sanity, Structured data, RSS, llms.txt - Learned: A personal site becomes more useful when every page doubles as a durable source of truth. - Links: https://www.thejacklau.com/about, https://www.thejacklau.com/llms.txt, https://www.thejacklau.com/profile.json - Related thesis: personal-sites-as-identity-infrastructure ### AI workflow playgrounds - Slug: ai-workflow-playgrounds - Status: planned - Type: Interactive tools - One-line summary: Small tools and demos people can use to explore search, agents, decision systems, and personal workflows. - Problem: Ideas are easier to understand when visitors can try an interface instead of only reading a claim. - Audience: Curious builders, founders, and operators. - Role: Builder - Stack: Next.js, AI workflows, Interactive UI, Sanity content - Learned: The site needs a tools shelf where experiments can be launched, documented, and connected back to writing. - Links: https://www.thejacklau.com/tools, https://www.thejacklau.com/projects - Related thesis: ai-agents-as-personal-operating-system, search-becomes-an-answer-and-action-interface ## Public Pages - Jack Lau: https://www.thejacklau.com | markdown https://www.thejacklau.com/index.md - About Jack Lau: https://www.thejacklau.com/about | markdown https://www.thejacklau.com/about.md - Now: https://www.thejacklau.com/now | markdown https://www.thejacklau.com/now.md - Ideas: https://www.thejacklau.com/ideas | markdown https://www.thejacklau.com/ideas.md - Projects: https://www.thejacklau.com/projects | markdown https://www.thejacklau.com/projects.md - Writing: https://www.thejacklau.com/writing | markdown https://www.thejacklau.com/writing.md - Books: https://www.thejacklau.com/books | markdown https://www.thejacklau.com/books.md - Lab: https://www.thejacklau.com/tools | markdown https://www.thejacklau.com/tools.md - Contact: https://www.thejacklau.com/contact | markdown https://www.thejacklau.com/contact.md - Searcle AI: https://www.thejacklau.com/projects/searcle-ai | markdown https://www.thejacklau.com/projects/searcle-ai.md - Jack Lau identity graph: https://www.thejacklau.com/projects/jack-lau-identity-graph | markdown https://www.thejacklau.com/projects/jack-lau-identity-graph.md - AI workflow playgrounds: https://www.thejacklau.com/projects/ai-workflow-playgrounds | markdown https://www.thejacklau.com/projects/ai-workflow-playgrounds.md - Designing Data-Intensive Applications: https://www.thejacklau.com/books/designing-data-intensive-applications | markdown https://www.thejacklau.com/books/designing-data-intensive-applications.md - The Beginning of Infinity: https://www.thejacklau.com/books/the-beginning-of-infinity | markdown https://www.thejacklau.com/books/the-beginning-of-infinity.md - The Cold Start Problem: https://www.thejacklau.com/books/the-cold-start-problem | markdown https://www.thejacklau.com/books/the-cold-start-problem.md - Hello, I'm Jack Lau: https://www.thejacklau.com/writing/hello-im-jack-lau | markdown https://www.thejacklau.com/writing/hello-im-jack-lau.md - What This Blog Will Cover: https://www.thejacklau.com/writing/what-this-blog-will-cover | markdown https://www.thejacklau.com/writing/what-this-blog-will-cover.md ## Opportunity Routing - Collaborate: Useful if you are building around AI search, agents, founder workflows, or personal software. mailto:jack.lau@thejacklau.com?subject=Collaboration%20idea - Investor or partner context: Send concise context, why now, and where the overlap is with current AI product work. mailto:jack.lau@thejacklau.com?subject=Investor%20or%20partner%20context - Founder intro: Best for sharp problems, early product questions, or useful people who should be connected. mailto:jack.lau@thejacklau.com?subject=Founder%20intro - Media or speaking: Route interviews, podcasts, panels, demos, and speaking requests with topic and timing. mailto:jack.lau@thejacklau.com?subject=Media%20or%20speaking ## Research Notes Used By The Site - LinkedIn: Public profile says former quant at Bridgewater and IMC, now startup founder building in AI, with University of Ottawa, CFA Level I, startup mentoring, and trading competition history.
