Pieter Levels runs a portfolio of over 40 products generating more than $3 million a year. He has zero employees. His primary tool is PHP — a language most developers consider outdated. He once said he kept meaning to learn something more modern, but his products kept taking off before he got around to it.
That’s the thing about lean builders. They don’t wait for the perfect stack. They ship with what works.
Most people planning a digital product spend weeks researching tools before writing a single line of content or code. They end up with a €400/month infrastructure before their first customer.
The trap is easy to fall into: AWS pricing, €200/month hosting tiers, payment processors, email tools billed per contact. Six weeks later, you’re burning €2,000/month with zero revenue.
The smarter move? Start at zero. Validate first. Pay only when revenue justifies it.
Here’s what a lean builder actually needs in 2025 — and what each tool costs at launch.
Landing page → Carrd
Clean, fast, and free for a single-page site. Paid plans start at $19/year. Not a typo — per year. One of the most underrated tools on the internet for getting something live quickly.
Forms and surveys → Tally
Free, unlimited forms with no branding watermarks. Connects to everything. Replace Typeform and save €50/month immediately.
Selling digital products → Gumroad
No monthly fee. Since January 2025, Gumroad operates as a Merchant of Record — they handle all global tax compliance including VAT, GST, and sales tax automatically. You can have a product live and for sale in under 10 minutes. They take 10% per sale, which stings at scale but costs nothing to start.
Newsletter → Beehiiv
Free up to 2,500 subscribers. Beehiiv now competes directly with Substack on subscriptions, Squarespace on websites, and Gumroad on digital products — all in one platform. Genuinely impressive for the price.
Automation → Make
Connect your tools, automate workflows, and replace what used to require a developer. The free tier covers most early-stage needs, and paid plans start at €9/month.
AI writing and thinking → Claude or ChatGPT
Both have capable free tiers. At this point, not using AI in your workflow is the most expensive decision you can make — not financially, but in time.
The goal isn’t a stack. The goal is a system that lets you find out if anyone cares about your idea — before you invest months of your life in it.
Good ideas are usually discovered, not invented. You only discover them by shipping fast and watching how real people react.
Carrd tells you if your message lands. Tally tells you who your customer is. Gumroad tells you if they’ll pay. Beehiiv tells you if they’ll come back.
That’s a complete validation loop. And it costs €0 to run.
You can build and launch for free. You’ll pay less than €200/month until you have significant revenue. That’s not a bootstrap fantasy — it’s the actual math of modern tooling.
The platforms have done the infrastructure work. Your only job is to use them well.
The builders winning right now aren’t the ones with the most sophisticated setup. They’re the ones who removed every excuse to delay shipping.
Pieter Levels used PHP. He still does. He says his competitive advantage is shipping before things are ready. The first version of Photo AI — now his biggest earner at over $130K/month — had output quality he described as terrible. People paid anyway.
The stack was never the point. The product was.
Start with what’s free. Ship before you’re ready. Upgrade when it hurts.
