Reducing hallucinations in retrieval-augmented chatbots for customer support teams

I often get the same questions from founders early in their journey: how much equity should I give away at pre-seed, how do I structure tech milestones so investors trust us, and how can I avoid giving up the wrong kind of control too early? Over the years — testing product hypotheses, building prototypes and negotiating term sheets — I’ve developed a practical framework that balances founder incentives, investor protection and the...

I’ve been testing smart home gear for years, and door locks are the one device that makes me pause: they protect your physical space and they're now tied into cloud services, voice assistants and mobile apps. Integrating a consumer smart lock with Alexa or Google Home can be convenient — unlocking your door with voice or automating guest access — but it also raises real security and privacy questions. In this piece I walk through the...

I read a lot of pitch decks. Over the years I’ve developed a short list of signals that separate persuasive AI product pitches from noise. When investors, partners, or product teams ask me how to tell whether an AI startup is pointing to real market fit—or just polishing a clever demo—I reach for the same mental checklist. Below I share that checklist, the reasoning behind each item, red flags I’ve repeatedly seen, and practical tests...

I’ve spent years helping small teams pick tools that actually make work safer and simpler, so when hybrid setups started becoming the norm I quickly realised the firewall conversation had to change. A firewall for a small business in 2025 isn’t just a box at the office edge — it’s the glue between on‑prem users, remote staff, cloud services and SaaS apps. Choosing the right one means balancing security, manageability and cost while...

Running a small e‑commerce site means juggling product listings, payment flows, customer support and marketing — all while hoping the infrastructure quietly hums along. When something goes wrong, "let’s fix it" is not a plan. Over the years I’ve helped small teams translate that gut reaction into repeatable actions. Below I’ll walk you through a pragmatic incident response playbook tailored to a small e‑commerce business: what to...

I recently led a migration of a mid-sized engineering team from Slack to a self-hosted Matrix setup, and I want to share the step-by-step playbook I used. If you’re contemplating the same move, you likely want more control over data, better federation options, or cost predictability. That’s exactly why we moved. In this guide I’ll cover planning, architecture choices, data migration strategies, day‑to‑day operations, and the...

When I started evaluating chatbots for customer support teams, one thing quickly became clear: hallucinations — confident but incorrect or fabricated responses from an AI — are the single biggest blocker to deploying models at scale. I’ve spent months testing retrieval-augmented pipelines, fine-tuning assistants, and watching support agents roll their eyes at answers that sounded plausible but were flat-out wrong. In this guide I’ll...

I’ve spent a lot of time testing phones, flashing ROMs and poking around settings to understand what really matters when you want privacy without paying flagship prices. If you’re trying to buy a privacy‑focused Android phone on a budget, you’ll quickly find that “privacy” can mean different things depending on whether you care most about software updates, limiting Google’s reach, hardware protections, or just reducing the number...

I get asked a lot which password manager will actually protect you from phishing, and the short answer is: some do a lot better than others — but only if you configure them correctly. Over the years I’ve tested and reviewed most major managers (1Password, Bitwarden, LastPass, Dashlane, Keeper, and the major browser-built managers), and the pattern is the same: a tool can only stop phishing reliably if you understand how its autofill and...

I remember the first time I tried to run a modern language model on my laptop: it was slow, memory-starved, and I spent more time swapping RAM than actually getting useful responses. Since then I’ve tested pruning, quantization, on-device runtimes and — most importantly — model distillation. Distillation is the technique that finally let me run capable models locally without paying cloud fees or sacrificing privacy. In this piece I’ll...
