In July, we published a piece called The Trust Problem in B2B Sourcing Marketplaces Nobody Talks About. That piece is a diagnostic. It sits on the buyer side of the marketplace, and it explains why Indian B2B buyers arrive on sourcing platforms with more skepticism than most founders account for.
This piece is different. It stays entirely on the vendor side. It is prescriptive, not diagnostic. And it is about a single, specific operational moment: the founder's first pitch call to a potential vendor.
Almost every B2B sourcing and trade marketplace founder we speak with underestimates this moment. They treat the first vendor call as a discovery conversation, a "let me tell you what we're building" chat, a fishing expedition. It is not. It is the moment where the vendor decides, in the first ten minutes, whether the founder in front of them sounds like someone who has built a marketplace before or someone who is about to learn on the vendor's time. That decision travels. Vendors in the same industry talk to each other. Getting this one call wrong is disproportionately expensive.
The three questions below are what separate a first vendor call that earns commitment from one that gets a polite "let's stay in touch." Every founder should have answered all three, in writing, before dialing.
Why the first vendor call is different from every call that follows
Every vendor call after the first one happens with some kind of signal in the room. You have other vendors on the platform. You have buyer traction. You have investor names on your deck. You have a case study. Something exists that the vendor can point to and say, "there is a marketplace here, and I am considering joining it."
The first call has none of that. What you have is a story about a marketplace that does not yet exist, told to a vendor who has a business that does. Everything you say has to earn its place against the alternative the vendor is already running: existing distributors, IndiaMART, ExportersIndia, WhatsApp groups, direct sales, marketplace listings on other platforms.
“The first vendor call is a sales pitch dressed as a strategy conversation, and the founder who pretends otherwise loses the room.”
Question 1: Why should this vendor make me a priority over the channels they already run?
This is the economic question, and it is the one most founders fail on. The default answer is a version of "we're new and different, we'll get you more buyers, and we're free during the pilot." Every word of that sentence is a losing move.
"We're new and different" tells the vendor you have no proof. "We'll get you more buyers" tells the vendor you have not thought about their unit economics, because more buyers of the wrong kind are worse than fewer buyers of the right kind. "We're free during the pilot" tells the vendor you do not value your own product, and it also tells them, correctly, that you will not be around for the long conversation.
The preparation that works is specific to the vendor. Before the call, know:
- What channels they already sell through, and roughly what share of their revenue each produces
- What their approximate unit economics look like on those channels (average deal size, take rate, fulfilment cost)
- What buyer segment your marketplace can bring them that their current channels cannot
- Why that buyer segment is worth their attention, in language they use
You will not have perfect information. You do not need it. You need enough to sound like a founder who has actually thought about their business, not just about your own marketplace.
Question 2: What am I promising, and can I actually deliver it in month one?
Every marketplace founder over-promises on the first vendor call, and does it out of fear. The vendor is politely non-committal. The founder panics. The founder says something like "we'll have five hundred qualified buyers on the platform by December," and now the founder has three months to make good on a number that was invented in real time.
This is the mechanism behind the "marketplace ghost" phenomenon. Vendors sign up in enthusiasm. Nothing arrives. Vendors go silent. When you call again, they do not pick up. The vendor did not decide the marketplace was bad. The vendor decided the founder was unreliable, which is worse, because unreliability is a permanent judgement.
The preparation that works is uncomfortable. Before the call, know:
- What you can honestly do in month one for this vendor, at the current state of the marketplace, without heroics
- What you can plausibly do in month two, given the vendors you already have or are actively signing
- What is genuinely out of scope for at least six months, and be willing to say so
- What "quiet" looks like: what the vendor should expect in weeks two and three when nothing much is happening, so silence is not misread as failure
A vendor pitched with a modest promise the founder keeps develops the kind of loyalty that seeds every future vendor recruitment call. A vendor pitched with a large promise the founder misses is a lost account and a story that travels.
Question 3: What does success look like for this vendor in ninety days, in numbers we agree on beforehand?
Most first vendor calls end with vague optimism and no metric. Both parties feel warm. Both parties disengage. Sixty days later, neither party can honestly say whether the arrangement is working, because neither party defined what "working" meant.
This is the accountability question, and it is the founder's job to force it into the room. Vendors will almost never define the success metric themselves, because doing so exposes them to accountability. The founder has to lead the conversation into it.
The preparation that works is to walk into the call with a proposed ninety-day test already sketched. Something like:
“Let me propose a way to measure this. In ninety days, if you have received X qualified enquiries through the platform, at an average deal size of Y, with a Z-percent conversion to closed business, this is working for you and we should scale it. If you haven't, one of us has to change something, and I'll want to have that conversation honestly with you. Does X-Y-Z sound like a fair test given what you're seeing on your other channels?”
The vendor will negotiate the numbers. That is the point. The negotiation is itself the value of the call, because it forces both parties to name what a working relationship actually looks like in numbers rather than in adjectives. A vendor who agrees to a specific ninety-day test with specific numbers is a vendor who has just committed something the marketplace can measure against. A vendor who declines to engage on the numbers is a vendor who was never seriously interested, and the founder now knows, in ten minutes, what they might otherwise have taken three months to find out.
What this sounds like when you say it out loud
The failing version of the first vendor call, condensed:
The version that fails
Hi, thanks for taking the time. So, quick background on us. We're building a next-generation B2B sourcing platform. We're going to bring transparency and technology to the industry. We've got a really strong team, we've been in stealth for a while, and we think there's a huge opportunity here. We'd love to have you as one of our launch vendors. It'll be free for the pilot, and we're expecting a lot of buyer traffic once we go live. What do you think?
The version that works:
The version that works
Hi, thanks for the time. Before this call I looked at your current channels: you're on IndiaMART, you have three regional distributors, and you've mentioned in your LinkedIn that you're actively looking to increase direct enquiries from the north Indian construction segment. That's the segment my marketplace is designed to bring you, specifically. Here's how, in one paragraph. I want to be honest about what I can and can't deliver in the first sixty days, because I'd rather under-promise. And I'd like to propose a specific ninety-day test we agree on now, so both of us know what success looks like before we start. Can we work through those three things?
The second version is not scripted or clever. It is prepared. That is the entire difference, and vendors hear it inside the first minute.
The wider truth
Vendors in the same industry talk to each other. If you sit down with one and sound like you have not done your homework, that story spreads faster than any pitch you can construct afterwards. If you sit down with one and sound like you have thought harder about their business than they have about your marketplace, that story also spreads.
The first vendor call is not a discovery conversation. It is the founder's introduction to the entire supply side of the industry they are trying to unlock. Answering these three questions properly is the difference between introducing yourself as a serious operator and introducing yourself as someone the industry will politely wait out.
