Meta Description: One person, 15 tools, $300/month in software costs. This is the actual stack that runs a six-figure AI consultancy without employees.

You do not need a team to run a serious business. You need the right tools and the discipline to use them.
This is the exact stack we use at AI Tool Alliance. One operator, 15 tools, $297/month in total software costs. Every tool listed below has been in daily use for at least a year.
Communication & CRM
Notion
Notion is not just a note-taking app. It is our CRM, project management system, content calendar, and knowledge base. The databases are the killer feature , we track every lead, every article, and every product decision in one place.
Check price on Amazon
What we use it for:
- Content pipeline tracking (50+ articles in various stages)
- Lead scoring and follow-up dates
- Product specs and feature roadmaps
- Team wiki and onboarding docs
Why it wins: Flexibility. Airtable is better for pure databases. Asana is better for pure project management. Notion is 80% as good at both in one tool.
Obsidian
Where Notion is collaborative, Obsidian is personal. It is our thinking tool , daily notes, idea capture, and long-form drafting. The local-first approach means our ideas are never trapped in someone else’s cloud.
What we use it for:
- Morning pages and daily reflections
- Article drafts before they go to Notion
- Research notes and source material
- Building a personal knowledge graph
Why it wins: Speed. Obsidian opens in under a second. Notion takes 3-5 seconds. For capturing ideas, that gap is the difference between writing it down and forgetting it.
Design & Media
Midjourney
We generate all our featured images, social graphics, and concept art with Midjourney. The quality is indistinguishable from human-created stock photography at 10% of the cost.
What we use it for:
- Blog featured images (saves $15/image vs Shutterstock)
- Social media graphics
- Product mockups and concept art
- Presentation backgrounds
The real value: Speed. We can generate, iterate, and finalize an image in 10 minutes. Stock photo searches take 30 minutes minimum and rarely find exactly what you need.
Hardware That Makes It Possible
MacBook Air M3
The M3 MacBook Air is the best laptop for knowledge work. Silent (no fan), 18-hour battery life, and fast enough for video editing, code compilation, and running local AI models.
Why we picked it: The Pro is overkill for 90% of users. The Air handles everything we do , writing, research, light coding, video calls , and the silent operation means no fan noise on recordings.
Kindle Paperwhite
This is not a gadget. It is a focus tool. We read 2-3 books per month on AI, business, and productivity. The Paperwhite is distraction-free, lasts weeks on a charge, and the backlight means you can read without disturbing anyone.
The Honest Stack Breakdown
| Category | Tool | Monthly Cost |
|———-|——|————-|
| Communication | Notion | $8 |
| Thinking | Obsidian | $0 |
| AI Images | Midjourney | $30 |
| AI Text | ChatGPT Plus | $20 |
| Email | Gmail | $0 |
| Calendar | Google Calendar | $0 |
| Hosting | WordPress | $15 |
| Analytics | Google Analytics | $0 |
| Total | | ~$73/month |
The remaining tools are one-time hardware purchases: MacBook Air, Kindle Paperwhite, Blue Yeti microphone, and a good monitor.
What We Do Not Pay For
– Project management software: Notion handles it
- CRM: Notion handles it
- Document storage: Notion + local files
- Stock photos: Midjourney replaces them
- Social scheduling: Manual posting (higher engagement)
- SEO tools: Free tier of Ubersuggest + manual research
The Bottom Line
You can run a six-figure business on under $100/month in software. The tools above are not the cheapest options , they are the ones that save the most time. Time is the only resource you cannot buy more of.
Start with Notion and a good laptop. Everything else is optional.
