Angel-invest in profitable micro-SaaS from $100. Every metric comes straight from Stripe — never a screenshot. Founders share a slice of revenue up to a cap; they keep 100% of their equity.
Investing in early-stage companies is high risk. You can lose 100% of what you invest and returns are never guaranteed.

How it works
Backrail separates interest from execution, so your commitment is never locked to terms nobody controls. Priority is reserved now; terms are fixed at execution.
A read-only restricted key — we reject anything with write access. MRR, growth and churn are computed from raw subscription data and re-verified every hour.
Reserve your spot in a round from $100. A pledge is a non-binding expression of interest: no charge, no commitment, withdraw anytime.
When a round fills, final terms are set with that day's verified MRR through a licensed partner. You confirm or walk away — then earn a monthly share of revenue up to the cap.
Live rounds
Every listing has 12+ months of history and revenue verified directly from Stripe — refreshed hourly, timestamped on the page.

Return simulator
Revenue-share with a cap is simple: the SaaS pays a fixed slice of its monthly revenue to backers until each backer has received a multiple of their investment. Money back monthly — no shares, no exit needed.
$500
Illustrative only, assuming ~30% yearly growth on a $3.8k-MRR SaaS raising $25k. Not a promise of returns — payouts can shrink, stop, or never reach the cap. You can lose everything you invest.

For founders
You built a profitable SaaS without VCs. Raise growth capital the same way — from your audience, against your revenue, keeping every share of your company.
Trust & risk
A marketplace for backing strangers on the internet only works if the numbers can't lie and the risks aren't hidden. So we lead with both.
MRR is computed from raw Stripe subscription data and refreshed every hour. Never self-reported, never a screenshot. Disconnecting Stripe delists the round.
Founders connect restricted keys that can only read. We verify the scopes and reject anything that could touch their money. Keys are stored encrypted, never exposed.
Startups fail — hiding it would make us a casino. Mortality statistics and founder post-mortems will be public. Honest failure is part of the system.
Real investments will execute through a licensed European crowdfunding partner (ECSPR) with full KYC. Until then, nothing on Backrail moves money.
You can lose 100% of what you invest.
Early-stage investments are illiquid and high-risk. Most small startups fail. Cross-border recovery may be impractical. Never invest money you can't afford to lose — and spread what you do invest across many projects.
