List your SaaS · Free

Find out how much your audience would invest in you

Connect your Stripe in read-only, and your verified-revenue page is live in minutes. No equity, no dilution, no board seats — pledges are free demand signal until you decide to execute a round.

Step 1 Connect your Stripe — read-only

Create a restricted API key that can only read your data — we reject anything with write access, server-side, before storing it.

  1. 1In Stripe, open Developers → API keys → Create restricted keyopen
  2. 2The link pre-selects Subscriptions, Customers, Prices, Charges and Invoices as “Read” — so one-time sales count too. Keep everything else on “None” and create the key
  3. 3Paste the key (it starts with rk_) below
  • Write access is rejected before anything is stored
  • Stored encrypted in a vault — never in plain text, never in your browser
  • Revoke it in Stripe anytime — your listing simply stops updating
  • Refreshed hourly; visitors only ever see the computed MRR

Step 2 Your page & your round

You'll sign in with X as this handle to publish — that's how founder identities stay verified

Round terms — indicative until execution

$1,000 – $200,000

5–8% is the healthy zone

Most deals land at 2–2.5×

Sign in with X to publish — free, takes seconds

Your listing is linked to your account so you can manage it later. The form above is kept in this browser while you sign in — only the Stripe key needs re-pasting (we never store it in your browser).

Pledges you receive are non-binding expressions of interest, not investments. Final terms are set only if and when the round executes, based on your MRR that day.

Backrail is not a bank, broker-dealer, investment adviser or crowdfunding service provider. Pledges made on Backrail are non-binding expressions of interest, not offers or commitments to purchase securities. No funds are collected, held or transferred on this platform. When investment rounds execute, they will do so through a licensed crowdfunding service provider under applicable regulation (ECSPR in the EU). Investing in early-stage companies involves significant risk, including illiquidity, lack of dividends and total loss of capital. Past revenue is not indicative of future performance. Revenue figures shown are computed from data provided by founders' Stripe accounts and refreshed periodically; Backrail does not guarantee their accuracy.
