Lattice's business card strategy turned a traditional networking object into a compact growth mechanism by embedding QR codes that connected to personalized demo signup pages while automatically crediting the person who handed out the card. The card itself was designed to be kept - using thicker stock, matte finish, and metallic ink - ensuring it stayed in wallets and on desks for extended visibility. Each card had a unique tracking code, allowing the team to measure which conferences and cards drove conversions; one San Francisco event generated 2,000 signups alone. At $0.40 per card ($2,000 for 5,000 units), the approach delivered a 2-to-1 signup ratio and massive ROI compared to traditional paid acquisition. The success hinged on three elements: targeting the right events (HR conferences and leadership summits), making the physical object memorable enough to scan, and building a passive referral mechanism that incentivized distribution without feeling pushy. The cardholder felt like they were doing something smart, not just handing out paper.
Each card had a unique QR code that took recipients to a personalized demo signup page and automatically credited the cardholder with a referral. The card also included a second QR code for a pre-filled email template, enabling multiple signups per card distributed.
The cards were printed on thick, premium stock with a matte finish and metallic ink, making them feel valuable enough to keep on a desk or in a wallet. This extended visibility beyond the initial conference moment, providing repeated opportunities to scan the code.
Each card had a unique QR code tied to the event or person distributing it, allowing them to measure exactly which conferences generated the most conversions; one San Francisco event alone produced 2,000 signups.
Lattice spent $2,000 for 5,000 premium cards ($0.40 per card), resulting in 10,000 signups - far cheaper than typical paid advertising campaigns that would cost tens of thousands for the same volume.
The referral credit was passive and automatic - cardholder received notifications when their card led to signups, but they didn't have to do anything extra or actively pitch others, making it feel like a smart networking tool rather than a sales tactic.
Our reviewer’s read on each dimension, with quotes from the episode.
The episode delivers a clear, replicable growth mechanism (physical card as referral trigger) with concrete mechanics explained step-by-step. However, it lacks deeper analysis of *why* this worked beyond surface-level novelty and gamification; there's minimal exploration of psychological triggers, comparison to other referral models, or failure modes beyond the obvious 'product readiness' risk. The insights are useful but not particularly dense - a competent operator could extract the core idea in 90 seconds.
The card had a QR code on it. But not just a link to a landing page. When you scanned it, it took you to a personalized demo signup page - but it also automatically credited the person who gave you the card with a referral.
Each card had a unique code. So they could see exactly which card at which event led to which signups.
The idea of using QR codes on physical cards for lead generation is not new, and the execution here (referral credit mechanism) is a sensible but relatively obvious extension of standard referral program logic. The framing as 'physical growth loop' and 'distributed growth engine' adds language novelty but not conceptual novelty. The approach is tactically sound but not contrarian or first-principles - it's a competent remix of known tactics (event marketing + referrals + tracking).
So the card itself was the referral link.
The card turned every handshake into a potential acquisition. And because the referral credit was automatic, the person handing it out felt like they were doing something smart - not just handing out paper.
Jack Altman (Lattice founder) is referenced as the source but never interviewed directly; the episode relies entirely on secondhand reporting by Lucas and Luna. While Altman's experience founding an HR SaaS at scale is relevant, the hosts provide no evidence they've spoken to him, dug into his notes, or pressed him on contradictions. This is a podcast about a founder, not a conversation with one - a significant limitation for substance.
According to Altman, in the first year they distributed about five thousand cards at events.
Altman said they spent about two thousand dollars on the first batch.
The episode provides strong specificity on core metrics (5,000 cards distributed, 10,000+ signups, 2:1 ratio, $2,000 cost, $0.40 per card, one SF event yielding 2,000 signups) and operational details (matte finish, metallic ink, thick stock, unique QR codes per event). However, it lacks supporting data: no revenue figures, conversion rates from signup to paid customer, timeline beyond '2018,' or verification of claims. Lattice's own public disclosures or third-party validation would strengthen credibility.
in the first year they distributed about five thousand cards at events. And those cards generated over ten thousand signups.
Altman said they spent about two thousand dollars on the first batch. That's forty cents per card.
The hosts ask logical follow-up questions ('was it novelty or something deeper?', 'what about cost?', 'did people feel weird?') and probe one meaningful tension (product readiness as a blocker). However, questions are largely confirmatory rather than challenging; neither host pushes back on unsupported claims, asks for comparative data, or explores alternative explanations. The conversation flows smoothly but lacks the friction that would deepen analysis. No genuine disagreement or probing skepticism emerges.
I think it's both. The novelty got people to scan the code. But the mechanism - the built-in referral loop - made it sticky.
But this only works if you're at the right events, right? If you're handing cards to the wrong people, it's just paper.

In this episode of Marketing for Startups with Fexingo, Lucas and Luna unpack a truly scrappy tactic: how a B2B SaaS founder used a single business card to generate over 10,000 signups. They break down the exact strategy - a creative QR code gimmick and a referral loop - that turned a networking tool into a growth engine. The episode also covers why the approach worked, how to adapt it for different audiences, and the one risk founders should watch out for. If you're tired of hearing about Twitter threads and cold emails, this one's for you. Plus, a quick word on listener support that keeps the show ad-free. #MarketingForStartups #StartupMarketing #ScrappyMarketing #GrowthHacking #BusinessCardMarketing #B2BSaaS #ReferralMarketing #QRCodeMarketing #FounderLedMarketing #EarlyStageGrowth #MarketingStrategy #ViralMarketing #NetworkingHacks #FexingoBusiness #BusinessPodcast #MarketingPodcast #LucasAndLuna #GrowthTactics Keep every episode free: buymeacoffee.com/fexingo

Lucas: So we talk a lot on this show about digital-first tactics - tweets, threads, docs, PDFs. But I want to look at something almost retro today. A piece of physical card stock. A business card.
Luna: Wait - like an actual printed business card? In 2026? Lucas: Yes. And not just any card - one that generated over ten thousand signups for a B2B SaaS startup.
The company is called Lattice, the HR and performance management platform. Back in their early days, around 2018, they were struggling to get traction among HR leaders. Luna: And a business card changed that? Lucas: It did.
The founder, Jack Altman, had this insight: HR leaders go to a ton of in-person conferences. They exchange cards constantly. So he designed a card that was literally a tiny, physical growth loop. Luna: Okay, I need to hear the mechanics.
Lucas: The card had a QR code on it. But not just a link to a landing page. When you scanned it, it took you to a personalized demo signup page - but it also automatically credited the person who gave you the card with a referral. If you signed up, the original card-giver got a nice notification.
Luna: So the card itself was the referral link. That's clever. Lucas: Exactly. But here's the real kicker - the card also had a second QR code that led to a pre-filled email template you could send to a colleague.
So one card could spawn multiple signups without the cardholder doing much. Luna: That's almost like a physical version of a referral program. And it worked? Lucas: According to Altman, in the first year they distributed about five thousand cards at events.
And those cards generated over ten thousand signups. That's a two-to-one ratio - for every card handed out, two people signed up. Luna: That's insane. But I wonder - was it the novelty, or was there something deeper?
Lucas: I think it's both. The novelty got people to scan the code. But the mechanism - the built-in referral loop - made it sticky. The person handing out the card had an incentive: every time someone scanned and signed up, they got notified.
That turned a passive networking moment into an active growth trigger. Luna: And speaking of things that keep going - if these marketing conversations have sparked something you've actually used, a couple of dollars a month genuinely keeps these episodes ad-free. Buy me a coffee dot com slash fexingo, if you've gotten something out of them. Lucas: Yeah, it really does make a difference.
And we keep it low-key - no sponsors, no mid-rolls. So if the show's been useful, that's the place. Luna: Alright, back to those business cards. What made this work beyond the referral loop?
Lucas: Another element: the card itself was memorable. It wasn't a standard glossy rectangle. It was a slightly thicker card stock, with a matte finish, and the QR code was printed in a subtle metallic ink. It felt premium.
People didn't want to throw it away. Luna: So it had to pass the 'keep it on my desk' test. Lucas: Right. And because it was physical, it sat in someone's wallet or on their desk for weeks.
Every time they saw it, there was a chance they'd scan it. That's a much longer shelf life than a tweet. Luna: How did they track the results? Was it all through the QR code?
Lucas: Yes. Each card had a unique code. So they could see exactly which card at which event led to which signups. They even knew which conferences were most effective.
One event in San Francisco generated over two thousand signups from a single batch of cards. Luna: That's wild. So the conference itself wasn't the growth channel - the card was. Lucas: Exactly.
The card turned every handshake into a potential acquisition. And because the referral credit was automatic, the person handing it out felt like they were doing something smart - not just handing out paper. Luna: What about the cost? Printing five thousand premium cards isn't cheap.
Lucas: Altman said they spent about two thousand dollars on the first batch. That's forty cents per card. Compare that to the cost of a paid ad campaign to get ten thousand signups - you'd be looking at tens of thousands, easily. So the return on investment was massive.
Luna: But this only works if you're at the right events, right? If you're handing cards to the wrong people, it's just paper. Lucas: Absolutely. Lattice was very intentional.
They targeted HR tech conferences, leadership summits, and meetups where decision-makers gathered. They didn't hand them out on the street. The context mattered. Luna: What about now, post-pandemic?
In-person events are back, but are QR codes still novel enough? Lucas: QR codes are ubiquitous now - menus, payments, everything. But the novelty isn't the QR code itself. It's the experience behind it.
If you scan a code and get something unexpected - like a personalized demo with a referral credit - that still works. The card is just the trigger. Luna: So the principle is: make the physical object a tool, not a token. Lucas: Exactly.
Don't just put a link on a card. Build a mechanism that rewards the giver and the receiver. That's what Lattice did. And it's replicable for any startup that does in-person networking.
Luna: What's the one risk you see with this approach? Lucas: The biggest risk is if the product isn't ready for the spike. If you suddenly get ten thousand signups from a conference, but your onboarding is clunky or your server can't handle it, you've wasted the opportunity. Lattice had their product in good shape, so they could convert those signups into active users.
Luna: So it's not just about the card - it's about the entire funnel behind it. Lucas: Right. The card is the top of the funnel. But if the middle and bottom are broken, the card is just an expensive piece of paper.
Luna: I also wonder about the referral aspect. Did people feel weird about getting credit for handing out a card? Lucas: Altman said some people loved it - they'd hand out dozens because they wanted to see their referral count go up. Others just handed them out normally.
But the key was that the referral credit was passive. You didn't have to do anything extra. So it never felt pushy. Luna: That's smart.
It gamified the act of networking without making it awkward. Lucas: Exactly. And it created a feedback loop. People who got a lot of signups from their cards felt motivated to hand out more.
It turned your sales team - or even your founder - into a distributed growth engine. Luna: So for a startup today, what would be the first step to try this? Lucas: Identify the one or two events where your ideal customer actually shows up. Then design a card that has a unique QR code per event - or per person if you want to track individual performance.
Make the landing page seamless, with a referral mechanism built in. And test with a small batch first. You don't need five thousand cards to learn. Luna: And the card itself - any advice on design?
Lucas: Make it feel like something worth keeping. Thick stock, unique texture, maybe a die-cut shape. But don't overdo it. The goal is to get them to scan, not to frame it.
Luna: Alright, so to sum up: a $2,000 batch of cards, 10,000 signups, and a lesson in turning networking into a growth loop. Lucas: That's the beauty of scrappy marketing. Sometimes the oldest tools, used in a new way, can outperform the latest growth hack. Luna: And it makes you think - what other physical objects could become marketing assets?
Lucas: That's a great question. Maybe that's a future episode.
