Build an audience before you build the product.
Describe what you are building and get a launch page you can edit like a document — one that collects real signups, grows itself through referrals, and turns the answers into evidence. The day you ship you already have an audience and an honest read on the demand.
Free to start. Paid plans meter what costs us money — emails, contacts, seats — not software.
Evidence supports testing or building.
How it works
A sentence in. An audience and a decision out.
Describe the idea
A sentence in, a whole launch page out — headline, questions and confirmation email. Then edit any of it on the page itself.
Ask the real questions
What they'd pay, which platform, how badly they need it, whether they'll test.
Let it spread
Every signup gets a referral link, a queue position and a leaderboard to climb.
Ship and tell them
Launch email, staged offboarding, segmented broadcasts from your own domain.
Understand whether the evidence supports building.
A signup count is not a decision. Osokoro measures seven things and shows you all of them: verified interest, stated willingness to pay, the price people name, the features they ask for, how far referrals travel, where the traffic came from, and how quickly signups arrive.
Stated willingness to pay is a statement, not a payment. Nobody on your list has been charged, has authorised a payment, or has placed a deposit or a preorder. What you get is what people said, at the moment they said it.

What you get
A page you edit on the page
Click a headline and type. Drag a block to move it. Ask for a change in plain English. Then host it on your own domain, or embed the form in the site you already have.
Referrals + leaderboard
Queue positions that move when people share. Public leaderboard optional.
Custom questions
Price, platform, urgency, pain — asked at signup, charted automatically.
Your sending domain
DKIM-verified sending, bounce and complaint handling, suppression lists.
Email that ships itself
Confirmation, verification, launch, staged offboarding and segmented broadcasts.
API + webhooks
REST endpoints, signed webhooks and Zapier. No enterprise call required.
Fraud controls
Double opt-in, CAPTCHA, disposable-domain blocking, referral abuse detection.
UTM + source analytics
Every signup keeps its campaign, referrer and first-touch source.
No badge
The editor, your colours, your questions and your perks are free. Taking our badge off the footer is the one thing a paid plan buys you here.
Four plans, priced on how much you send.
Full pricing detail →Email volume is the part that costs real money, so that is the part that is metered. The $20 Everything plan includes every ordinary premium feature; Starter is a smaller entry point with fewer of them and lower limits. The pricing page lists exactly which, generated from the same flags the app enforces.

A future worth building
The future begins as a signal.
Before a world is built, someone has to believe it should exist. Osokoro helps builders find that first community, listen closely, and turn possibility into evidence.
Our mission is to build tools for the builders of the future.
