Mini-tools strategy / portfolio
Operate a portfolio of small single-purpose SaaS tools that each earn a little, monetized via ads and freemium.
The idea, in plain language
Operate a portfolio of small single-purpose SaaS tools that each earn a little, monetised via ads and freemium. Across 14 indie founders the videos quote a range from $10K/month (Max, 28 apps) through $35K/month per app (Loïc, Samuel) and $100K/year from two AI projects (Ramsri) up to $1M+/year from 20 plugins (Katie Keith), $4.5M/year on ~90% margins from 5 Shopify apps (Erikas), and $30M/year combined from two apps (Will Cannon). Started costs are typically near-zero — a developer, a domain, a Stripe account — and the unit economics are heavily skewed toward shipping speed: a few weekends of work plus SEO or marketplace distribution. The customer is either an end-user hitting a free tier that funnels into a paid plan, or an app-marketplace shopper; margins are quoted at 80-90%+ once a tool sticks.
Where the sources agree
- Ship a lot, ship fast, abandon losers — Max (28 apps), Ramsri (2 apps), Adam (app-a-month) all run on a build-and-cut cadence.
- Most operators run each tool on the same minimal template (Next.js + Stripe + Plausible / OpenAI + Postgres), so adding a fourth app is mostly a copy-paste job.
- Free tools and lead-magnet calculators are the marketing channel: Bhanu's SiteGPT hit $13K/month by ranking free tools in search and funnelling users to the paid chatbot.
- High margins are normal — Erikas' 5 Shopify apps do $4.5M/year with ~90% margins and effectively zero marketing spend via the marketplace.
- Portfolio diversification beats single-product bets for solo founders: Jure ($60K/mo from 4 apps), Katie ($1M+/yr from 20), Rush ($3M/yr from 24), Nicole ($150K/mo each across multiple apps).
Where they differ
- Loïc's builder+creator co-founder playbook pairs an engineer with a creator who owns the audience; Katie, Ramsri and Max all go solo without depending on a personality.
- Distribution differs sharply: Erikas rides the Shopify app marketplace; Nicole runs a UGC creator ops team; Will Cannon clones proven winners with better funnels; Samuel clones 'without innovating'.
- Some operators (Adam, Nico) treat apps as flipped assets — Nico sold two for a combined $265K — while Rush and Katie build long-running indie portfolios they keep operating.
- Nico locked himself in a hotel room to build 17 apps; Cody's Canva agency targets $80K/month at 80% margin — speed versus productised operationship as competing models.
- Nicole's UGC pipeline is human-managed; Will Cannon's growth is funnel optimisation; Erikas' growth is the platform itself — three different paths to nine-figure-style outcomes for solo founders.
