The referral tool you use
before you need Cello.
Cello is a real company building a real thing. They're great. They're also priced, shaped, and sold for a specific stage of B2B SaaS — the stage after you've proven referrals work. Herd is for the stage before that.
- You're between $0 and $15M ARR.
- You're on Stripe Billing today.
- You want to be live this week, not next quarter.
- A $49/mo minimum before you've shipped a single reward feels wrong.
- You'd rather pay a % of referred revenue than a flat fee that hits your credit card whether the program works or not.
- You don't have 5 days of SDK integration work in your sprint.
- You're past $15M ARR and referrals are already a real channel.
- You have a dedicated growth hire who lives inside your referral program.
- You need SSO, SOC 2, custom DPAs, and a procurement cycle.
- Multi-currency automated payouts across 40+ countries are table stakes.
- Your CFO wants predictable flat-fee pricing, not a revenue share.
- You can afford a 5-day SDK build because the program clears that cost in a week.
Most referral tools pretend to serve every stage.
We don't.
Herd builds for one scaling phase well: roughly $0 to $15M ARR, on Stripe, founder or early growth hire running the program. Cello builds for the phase after that — PLG-stage teams with partnerships leads, multi-currency payout needs, and procurement cycles.
Trying to be both is how companies lose both. So we're honest: if the Herd one-liner ("free until $1K/mo, then a rate that bends down as you scale — 10% → 5% → 2% → flat contract") doesn't match your shape anymore, Cello is the next tool. We will actively say so on a call.
Graduated customers aren't churn. They're proof the product worked. Some of the best case studies we'll ever have are going to end with "Herd took us from $1M to $12M. We're now on Cello." That's not a failure mode — that's the shape of doing this well.
