Reach the people who recommend and endorse your products.
We aggregate every major partner network into one catalog, and put your product in front of the referrers, creators, consultants and agencies whose audiences buy on their say-so: endorsements, not ads.
Easy to find. Easy to promote. Anywhere your referrers already recommend.
The referral economy. Not the ad economy.
You already pour capital into renting attention. We help you earn it instead, from the exact people your customers ask before they buy.
Warmlink turns those recommendations into revenue.

What is Warmlink?
A marketplace of trusted referrers
Consultants, agencies, creators and newsletter writers who recommend software every day. Our AI builds each of them a curated stack, and drops your offers where they fit.
Distribution you can't buy
Your program shows up where people already ask “what should we use?” A proposal, an onboarding doc, a newsletter. A recommendation from someone they trust, not an impression.
One approval. Performance-only.
List once on the partner network you already run. You pay the commission you already pay, only on verified purchases. No fees, no contracts, nothing to manage.
In program terms
One publisher in your program. Many trusted voices behind it.
Warmlink is a publisher: one partner account in your program, and the publisher of record for every sale we send. You approve us once, and we vet, onboard and pay the members who recommend you.
Your link lives only on Warmlink. Stacks, the marketplace, brand pages and the widget, all on warmlink.io. Never on a random site you've never heard of. Members bring buyers to those pages from wherever their audience is; your link is never where they post.
Our rules protect your brand. Members may not bid on your name in paid search, use it in a domain or handle, list you as a coupon, spam, or stuff cookies. We enforce that, so you don't police hundreds of small partners.
Keep your direct partners. Warmlink isn't exclusive. Your own affiliates and creators carry on as before; we reach the referrers your program never did.
Vouches, not reviews
Buyers tune out ads. When they look you up, they find star ratings they don't trust and reviews too long to read.
What moves a buyer now is real people, vouching for you honestly, as it happens.
A WHY, not an essay
People don't like writing long reviews, and they don't like reading them. A vouch is one short sentence on why: quick to write, so people write it, and quick to read, so people read it.
Three clear ranks, not stars
Vouch, recommend or avoid. No stars to average and argue about: a fast, accurate call to make, and one anyone reads at a glance.
Real people, real reputations
Every vouch carries the person's name and face, in front of the people who know them. They stand behind their rank with their own reputation, which is why it's believed.
Live and honest
Vouches show the moment they're made, and people change them when their view changes. Every six months we automatically ask members whether they still stand behind each one. No paid placement, no review campaigns, nothing years out of date.
You know this pain
Your customer acquisition cost (CAC) runs twice a new customer's first-year revenue, and CAC payback takes well over a year.
$2.00
New CAC ratio: sales and marketing spend for every $1.00 of new ARR4
16 months
median CAC payback. The bottom quartile waits 24 months or more3
80–90%
of your registered referral partners may never have made a sale2
You pay for the clicks, the impressions and the demos before anyone buys. Then you wait well over a year for CAC payback, if the customer stays that long. Every year the same budget buys less, and the partner program you built to fix it mostly sits idle.
Warmlink flips the order. You pay after a customer buys, never before. Your CAC through Warmlink is typically $0.25–$0.50 per $1.00 of first-year ARR, and nothing for the ones who don't buy.
A commission is a marginal cost, so it can't run ahead of the revenue it brings in. Your paid-channel spend lands in CAC whether the campaign works or not. This doesn't.
And it compounds. Agencies with large rosters, teams who spec software for every client, are joining now. One approval from you can put you in front of hundreds of trusted voices at once.
Why software, why now
Businesses spend about $300 billion a year on SaaS, and it grows about 19% a year1. High prices, high commissions, and customers worth far more than a single sale: that's exactly where a trusted recommendation pays off most, so business software is our focus. Consumer brands are welcome too.
What it looks like if HotRev takes off
Every stack owner brings traffic. That traffic attracts new stack owners, who bring more traffic, each layer compounding on the last. Here's the shape of that network effect, modeled from a single seed stack.
Model: new revenue from one seed stack over 24 months (new ARR, for a SaaS vendor)
An illustrative model of the network effect, not a forecast of your results. Warmlink launched in June 2026, so this is the shape of the mechanism, not measured performance. We plot a band rather than a line because the one parameter that drives the shape, r, is genuinely uncertain.
See the model & assumptions →Hide the model ↓
Part 1: new stacks seeded by one stack
N(t) = (r · t)³ / 6
The cubic isn't decoration: it's a three-stage cascade: a stack brings traffic, traffic brings a new stack owner, that owner opens a stack. t³/6 is t³/3!, the third integral of a constant rate. The band plots r = 0.8, 1.0, and 1.25.
Part 2: total network revenue from one seed stack
GMV(t) = tΣi=0 N(t−i) · S
t = time period (months)
N(t) = new stacks seeded by one stack at month t
i = each month since launch (0 through t)
r = spawn rate, how readily one stack seeds the next. This is the only parameter that changes the shape.
S = sales per stack per month (modeled here at AOV $80 × 5 sales = $400). Linear, it scales the axis, never the shape.
Where the uncertainty lives. HotRev terms vary by offer, whether it applies and how much you choose to fund it. All of that lands in exactly one place: r. A stronger incentive means the next referrer is likelier to show up, a faster spawn rate, a steeper curve. It never changes S, because what your customers spend doesn't depend on how the referrer is paid. That's why your terms are worth a conversation, not a footnote.
What we ask of you
Approving us is the one we hope every brand says yes to. Everything after that is a lever you choose, and we'll walk through it together. Transparent from day one, nothing forced.
For SaaS & B2B
Approve us as a partner
List your program in the marketplace. It's zero-risk: performance-only, on verified purchases, at the commission you already pay, and we activate the referrers your program never reached. We integrate quickly with the major affiliate networks and with platforms like Tolt and FirstPromoter. For a listing to work, we need:
- SubID links. Your tracking links accept a SubID parameter, so every sale is credited to the member who sent it.
- Terms that allow a marketplace. Your program terms let us list you in our marketplace and share links with our members, who promote you as referrers.
- Your name and logo. Permission to show your brand name and logo on your listing and in members' stacks.
- Conversion reporting by SubID. Sales and refunds reported per SubID, by API, postback or export, so we can pay members accurately.
- A fair cookie window. 30 days or more. Referred buyers take time to decide, and a short window loses the credit.
- One partner account. You pay Warmlink as one partner, and we pay each member their share.
- A timely decision. An approval decision within 14 days, so members aren't left linking to a pending program.
- Your payout terms. Your minimum payout and payment schedule (net-30, net-60), so members know when they're paid.
- Your brand guidelines. Any claims members shouldn't make about your product. We pass them on to every member who lists you.

We're live, and the network is early. First movers become the default recommendation. No fee, a quick approval on the program you already run, commission only when a real purchase happens.
We know software, and we love it
We've spent our careers building software and helping teams choose it. Warmlink exists so the right product finds the right customer, and both succeed: they get a tool they'll keep, and you get a customer who arrived already trusting you.

AI assistants that can cite your vouches
Programs from PartnerStack, Impact, Rakuten, Awin, CJ and more. Vouches in Claude, Grok and Gemini through our MCP connector.
Honest by design
Every vouch carries a real name and a reason. Brands can't hide, edit or reorder them, and there are no paid placements. Each reason is checked before it's published: profanity, slurs, threats, harassment and spam are kept out. Honest criticism stays in.
Paid only when it works
Performance-only, on verified purchases. No listing fees, no contracts, no spend on buyers who never convert.
Success on both sides
We earn only when your customer buys, so we're built to send people your product fits, who stay and vouch for you in turn.
Who's behind this
Warmlink is my answer to a simple observation: referrals are the most trusted, highest-converting force in commerce, and they're wildly underutilized. The referral graph is the asset; Warmlink is how the people who build it finally capture its value.
