The Lean Business Stack: Exactly What I Use to Run a One-Person Business in 2026
This post may contain affiliate links. Read my disclosure here.
Every few months, someone publishes a “tools I use” post that’s really just a list of affiliate links dressed up as advice. You can feel it immediately: the suspiciously glowing reviews, the lack of anything negative, the tools that somehow all happen to have affiliate programs. Not because someone paid me to say so. (You can’t buy me, hot dog man!)
I built a business from zero to nearly $10 million in annual revenue with over 100 employees in 2 locations. I’ve used a lot of software. Most of it was fine. Some of it was actually good. A few tools I’ve tried were a complete waste of time and money, and I’ll tell you which ones and why.
What follows is my actual current lean business stack, the tools I use every week without thinking about it. The ones that earned their place by actually being useful.
The Lean Business Stack Philosophy: Everything’s Gotta Earn Its Place
When you’re running lean, no ops team, no IT department, no one to blame but yourself when something breaks, your relationship with software changes. Every tool has to carry its own weight. Monthly subscriptions add up. Switching costs are real (and annoying, and coming out of YOUR OWN POCKET). And the cognitive overhead of managing a bloated stack is a tax on your thinking that most people underestimate.
My rule: if I haven’t used it in two weeks without being reminded, it’s gone.
Here’s what survived.
AI Tools
This is where I’ll spend the most time, because AI is the category where the hype is loudest and the honest takes are rarest.
Claude — My Lil Buddy
Claude is my go-to AI, and the gap between it and the alternatives has gotten wider, not smaller.
The reason isn’t the model itself, though the reasoning is legitimately strong. It’s the architecture of how I use it. Claude Projects lets me build persistent context. I can tell Claude exactly who I am, how I think, what I’m building, and what I need, and that context lives in every conversation. I’m not re-explaining myself from scratch every time I open a new chat.
This matters more than people realize. Most people use AI like a vending machine: put in a prompt, get out an output, repeat. The results are mediocre because the AI has no idea who you are or what you actually need. The unlock is treating it like a thinking partner you’ve properly briefed. When Claude knows my background, my goals, my constraints, and my working style, the outputs stop sounding like AI and start sounding like something I’d actually use.
Practically: I use Claude for drafting, strategy, research synthesis, connecting to my Gmail and Google Drive, creating calendar events, working through decisions, and increasingly as a sounding board when I need someone to push back on my thinking rather than just agree with me.
Limitations: hallucinations are real. Claude will occasionally state something confidently that isn’t true. My fix is to ask for references and sources whenever I need something factual. It doesn’t eliminate the problem but it makes it manageable. If I’m verifying something important, I verify it independently.
Bottom line: The tool I’d keep if I could only keep one.
Perplexity — Research
Perplexity is where I go when I need current information with citations: market research, recent news, checking whether something I think I know is still accurate. I actually use it at my day job too (yes, I have a day job. Consider it my Bruce Wayne time.) The citations are generally real (unlike some AI tools that hallucinate sources) and it’s fast.
The limitation I’ve run into: when you upload a document, Perplexity leans hard on that document even when you’ve explicitly asked it to research wider sources. It can feel like it’s doing research but is actually just repackaging what you already gave it. I’ve learned to be very explicit in my prompts about ignoring uploaded context when I want external research, and to cross-check anything that feels suspiciously circular.
Bottom line: Useful for research, especially with citations. Know its blind spots.
ChatGPT — Dropped
I used ChatGPT for about eighteen months before I stopped. The breaking point wasn’t a single thing, it was a pattern.
ChatGPT is profoundly agreeable. Not helpful-agreeable. Sycophantically-agreeable. I spent an hour one afternoon troubleshooting a problem with it. I’d describe what I’d tried. It would suggest something. I’d explain that I’d already tried exactly that and describe the result. It would say “you’re absolutely right, let’s try this instead” and suggest the same thing again. Every time I called it out, it apologized and agreed. And then did the same thing again.
If you need a tool that validates everything you say and never disagrees, ChatGPT is excellent. If you need something that will actually help you think through hard problems, find a tool that’s willing to tell you you’re wrong.
Bottom line: Dropped. Not coming back.
Task Management
Things 3 — Daily
I’ve tried OmniFocus, Todoist, ClickUp, Monday… and some task managers you’ve probably never even heard of. Evernote workarounds have gotten into the mix at some point. It gets weird when you’re on the hunt for the right system.
Things 3 is what I came back to.
It’s opinionated software. It has a specific philosophy about how tasks should be organized (Today, Upcoming, Someday) and it doesn’t try to be a project management platform. For one person running multiple projects and a full-time job simultaneously, that simplicity is the feature. I can capture something in under five seconds and trust it won’t disappear into a system so complex I stop using it.
The Apple ecosystem integration is seamless. The design is sharp. The price is a one-time purchase, which in a world of endless SaaS subscriptions feels almost radical.
Bottom line: Best task manager for solo operators who actually want to use their task manager.
Finance
QuickBooks — Monthly
I use QuickBooks for my LLC. I’ve also used Xero, Wave, and Puzzle, and at enterprise level, NetSuite.
Xero was the standout when I was running a physical products business. The automatic transaction categorization and rules were exceptional. It learned fast and my reconciliations were a breeze in a way that QuickBooks has never quite matched. If you’re in e-commerce or selling physical products, Xero is worth a serious look.
For a service-based LLC doing straightforward US business though, QuickBooks is the standard. Accountants know it, integrations exist for everything, and when tax time comes you’re not explaining an exotic system to your CPA. Wave is free and fine if you’re very early stage.
Bottom line: Xero if you’re in physical products. QuickBooks if you want the safest, most boring choice. Wave if you’re pre-revenue and watching every dollar.
Design
Canva + Adobe Creative Cloud — Situational
Full disclosure: I’m actually a designer. My preference, when I have the time and the brain space, is Adobe. Creative Cloud is the more powerful suite, and the image generation through Firefly living natively where I’m already designing and working makes things feel pretty fluid (especially if you can prompt it correctly). Way-back-when, content aware fill changed my life, and while Firefly doesn’t feel quite as life-changing (which sounds weird as it’s infinitely more powerful), there’s a lot to be said for working in one place and not collaging different bits and trying to jerry-rig your images together.
But Canva exists for a reason, and that reason is it’s everywhere, it’s fast, and it’s extraordinarily cheap for what it does. When my brain is dead and I need something to look considered in twenty minutes, Canva is what I open. The brand kit feature means I’m not manually entering hex codes every time. It handles probably 80% of what I actually need to produce on any given day.
I also tried Getty’s image generation. Getty uses its own licensed content, so you’re properly covered to use the output (a real differentiator). The problem is the results are… strange. Like, truly weird. Licensed properly, weird visually. Worth knowing it exists, but manage expectations.
Bottom line: Canva for speed and budget. Adobe when quality and time allow. Getty image gen if you need airtight licensing and have a high tolerance for unexpected results (or inexplicably bare feet no matter how hard you prompt shoes).
Documents
Google Docs — Default
Google Docs is the default for anything collaborative. It’s not the most feature-rich word processor and it doesn’t need to be. It lives in a browser, which means no version control nightmare. It integrates with everything. It just works.
KISS. Keep It Simple, Stupid. Give me my Docs and my Sheets and my Forms and my Drive. Easy, done, next.
Bottom line: Google Docs. It does what I need. Moving on.
The Takeaway
Most people approach AI tools asking “what can this do?” The better question is “what does this need to know about me to actually be useful?”
The tools on this list aren’t necessarily the best in their categories on some abstract benchmark. They’re the ones that fit the way I actually work: fast, lean, context-dependent, with a low tolerance for complexity that doesn’t pay off.
There’s something about everything I’ve written above that is ignoring a potentially harsh-sounding truth. And that’s the fact that if you have zero personality, no true preferences or ways of thinking that feel “you”, and no actual perspective or opinion on anything…AI can’t fix that. That’s on you, and that’s some stuff you’ll have to figure out without the little robot in your pocket. Let the machines be the machines, and let them help you be more of whatever you already are. The people who get the most out of these tools aren’t the ones with the best prompts. They’re the ones who showed up with something to say in the first place.
Invest time in teaching your tools who you are, because a good context document will do more for your output quality than any feature upgrade ever will.
