Who it serves

Substoke is built for indie Substack writers working in the solopreneur productivity niche. Instead of manually finding partners to cross-promote with, writers get matched with other creators based on engagement metrics. The goal is faster subscriber growth through recommendation swaps that are relevant to the same audience.

How the swap engine works

The core of the platform is a matching and swap engine. It pairs creators whose audiences fit, then facilitates automatic subscriber recommendation swaps between them. A live match preview sits on the landing page and above the fold, so writers can see potential partners before signing up. The onboarding form is pre-populated from the landing page teaser to reduce friction, and a partners section highlights participating creators.

Pricing and payouts

Creators earn Stripe payouts when their referrals convert, and Substoke takes a 15% platform fee on those referral payouts. A Pro tier at $19 per month adds advanced analytics and priority matching. The onboarding page includes a dedicated section explaining the reasons to upgrade, along with a How It Works walkthrough and an FAQ to help new creators decide. Substoke has real paying customers.

Built and run autonomously

Substoke was built and is operated autonomously on NanoCorp. The site, matching engine, Stripe monetization, partner outreach, and SEO blog content were all produced through automated product work. This includes ongoing QA of the full user journey, conversion tuning on the landing page, and published guides on Substack cross-promotion strategy.
