Build Your One-Person Tech Stack Before You Buy a Single Subscription

Here's a fun exercise: open your bank statement and count every SaaS subscription you forgot you had. For most solo founders, the number is somewhere between hilarious and alarming. The tools weren't the problem — buying them one at a time, without a plan, was.

A tech stack should be decided like a grocery list: know the meals first, then shop. So let's walk through the seven categories every one-person business actually needs, the gotchas buried in their pricing pages, and three complete stacks you can run starting today.

The 7 Categories (and the Traps Inside Them)

1. Website builder. Wix, Squarespace, and Carrd all look affordable until you need e-commerce, a custom domain, or remove their branding. Trap: the advertised price is always the annual-billed, feature-stripped tier.

2. Email marketing. Mailchimp famously outgrew its "free forever" promise — the free plan now caps you at 500 contacts with limited automations. Trap: pricing that doubles at exactly the moment your list starts working.

3. Analytics. Google Analytics 4 is free but has a learning curve like a cliff. Plausible and Fathom run $9–14/month with zero configuration. Trap: spending weeks configuring a free tool you'll never open.

4. Payments. Stripe and PayPal take ~2.9% + 30¢ per transaction. That's fair. Trap: platforms that add their own markup on top of Stripe fees.

5. Automation glue. Zapier, Make, and newer AI-native tools connect your apps so data moves without you. Trap: Zapier's free plan limits you to 100 tasks a month — one busy week and you're bumped to $20.

6. Scheduling and CRM. Calendly's free tier is genuinely useful. A full CRM can wait until you have customers to manage.

7. AI assistant. One paid AI subscription now replaces a surprising chunk of early-stage copywriting, research, and admin work. This is the newest category on the list and arguably the highest-leverage dollar a solo founder can spend.

Stack Recommendations by Budget Tier

The $0–10/month Stack: "Bootstrap"

• Website: Carrd ($19/year, basically free) or a free Notion site
• Email: MailerLite free tier (up to 1,000 subscribers)
• Analytics: GA4, free
• Payments: Stripe, pay-per-use
• Automation: Zapier free tier, carefully rationed
• AI: Free tiers of your favorite assistant

This stack runs a real service business. Its ceiling is low, but the floor is zero.

The $30–60/month Stack: "Momentum"

• Website: Squarespace or WordPress on a solid host (~$16–25/mo)
• Email: MailerLite or ConvertKit paid tier
• Analytics: Plausible or stick with GA4
• Automation: Make.com starter plan (more generous than Zapier at this level)
• AI: One paid AI subscription (~$20/mo)

This is the sweet spot for most US solo founders earning their first few thousand a month. Everything scales comfortably to roughly $10K/month in revenue.

The $100–150/month Stack: "Operator"

• Everything in Momentum, plus:
• CRM: HubSpot Starter or a Notion-based system
• Scheduling + payments bundled into a platform like HoneyBook
• Upgraded AI tooling for content and customer support

Upgrade to this tier only when admin work starts eating real hours. Tools should buy back time, not prestige.

Three Rules Before You Swipe the Card

1. Never buy a tool for a problem you don't have yet. Enterprise CRMs are where enthusiasm goes to die.
2. Check the contact-tier math. Model your email tool's price at 2x and 5x your current list size. If it doubles in cost, look for a flatter pricing curve.
3. Prefer tools that bundle. Every tool you cut is one fewer login, invoice, and thing that breaks at 11pm.

The best stack isn't the shiniest one — it's the boring, connected, mostly-free one you'll still be using a year from now. Pick your tier, set a calendar reminder to re-audit in 90 days, and spend the rest of your energy on the only thing that actually grows a business: getting customers.
