Four founders couldn’t afford transit passes to their own investor meetings.
That’s not a metaphor. That’s 2014, in a cramped house in Toronto’s Koreatown, building a workplace app called Pod that nobody wanted.
I’ve run marketing teams through plenty of near-death product moments. Few stories capture the pivot instinct better than this one. PartnerStack didn’t succeed because its founders built a great product. They succeeded because they noticed something more valuable happening on the side.
That’s the essence of partner-led growth, and it’s a lesson every marketing leader should sit with.

A Side Hustle Became the Business
Pod was failing. So the team improvised.
They paid outside agencies a commission to sell the software for them. Simple referral math, nothing fancy.
The product kept stalling. The referral channel didn’t.
Within months, larger companies weren’t calling to buy Pod. They were calling to ask how the founders built the referral engine itself.
That’s the moment I’d flag for any founder or CMO: when customers care more about your process than your product, you’re looking at the wrong business plan.
Betting Against SaaS Orthodoxy
In 2015, a venture capitalist reportedly called this idea the dumbest thing he’d ever heard.
His logic wasn’t crazy. The SaaS playbook of that era said pour everything into direct sales. Partner marketing was viewed as a consumer affiliate gimmick, run through spreadsheets and manual payouts.
But that orthodoxy ignored something obvious. Most global commerce doesn’t move direct-to-consumer. It moves through dealers, resellers, and agencies.
The founders bet that software would eventually behave like every other industry. As paid acquisition costs climbed, the company with the strongest network of trusted third parties would win, not the one with the biggest ad budget.
I’ve watched this exact dynamic play out in my own campaigns. Direct channels get more expensive every year. Anyone ignoring indirect channels is leaving growth on the table.
Selling Before Building
Before the product existed, the team put up a landing page under a cheap domain name: GrowSumo.
They cold-called dozens of B2B SaaS companies. Twenty signed up in two weeks, based on a promise, not a product.
That’s aggressive. It’s also smart demand validation. You don’t need a finished platform to test whether the market wants what you’re describing.
But there’s a trap hiding inside that success story.
When Growth Metrics Lie to You
Y Combinator accepted the team based on that customer discovery. Then the pressure to show week-over-week growth kicked in.
They chased top-of-funnel acquisition. Launched on Product Hunt. Got the applause.
And it nearly cost them the business.
The Base CRM Wake-Up Call
Here’s the part every growth-obsessed marketer needs to read twice.
PartnerStack landed Base CRM as a marquee customer. Base CRM’s partner program reportedly drove more than half of its revenue, and its team handed PartnerStack a detailed roadmap for what the platform actually needed.
PartnerStack ignored it. They were chasing broader, less qualified sign-ups instead.
Base CRM churned months later, frustrated with an inadequate platform.
I’ve seen this mistake inside my own teams. Vanity growth feels great in a board deck. It’s often financed by walking away from the customers who actually matter.
Choosing Depth Over Vanity Growth
The Base CRM loss forced a real reckoning.
The founders spent roughly a year on unglamorous engineering work. Prorated commissions. Multi-tier reseller tracking. Automated tax handling across markets.
Most importantly, they replaced browser-pixel tracking, which broke constantly under ad blockers, with server-to-server tracking. That single decision meant partners actually got credited for complex, multi-touch deals.
This is the unsexy truth about partner-led growth: it lives or dies on trust infrastructure, not marketing copy. If your partners don’t trust the attribution, the whole model collapses.
From Software Tool to Distribution Engine
Once the platform stabilized, the strategy shifted again, and this is where the story gets genuinely interesting.
PartnerStack stopped positioning itself as software that helped companies manage partners they already had. Instead, it connected B2B SaaS companies to a pre-vetted network of affiliates, agencies, and resellers it already controlled.
That’s not a product feature. That’s a two-sided marketplace.
A startup could plug in and instantly access a performance-based sales force that only got paid when deals closed. Meanwhile, PartnerStack solved its own customer acquisition problem in the process. Every new brand brought partners. Every partner attracted more brands.
You can see this network effect in how quietly the company rebranded from GrowSumo to PartnerStack. No big launch campaign. They pushed new branding to partners, who updated their own content across the web.
The ecosystem did the marketing. That’s the whole point.
Speaking to the CFO, Not the Marketing Team
Even with marketplace momentum, PartnerStack hit an internal wall at enterprise accounts. Partner marketing was treated as a silo, disconnected from revenue targets.
Pitching “partnerships” to a C-suite audience is a losing move. Executives care about pipeline, conversion, and capital efficiency. They don’t care about portal logins.
So PartnerStack retrained its own sales team and its customers to drop the jargon entirely. They repositioned partner-led growth as the most capital-efficient path to revenue, a direct answer to rising acquisition costs.
That’s a positioning lesson I’d want every marketing director to internalize. The best channel strategy in the world still needs a finance-fluent narrative to survive budget season.
Why AI Search Changes the Math Again
By 2025 and 2026, buyer behavior fragmented once more. People started asking ChatGPT and Gemini for software recommendations instead of running search queries or booking sales calls.
Large language models lean heavily on third-party, user-generated content. A brand relying purely on its own website risks near-total invisibility in AI-generated answers.
PartnerStack leaned into this shift, calling it Answer Engine Optimization. The logic: mobilize independent affiliates, consultants, and reviewers to generate authentic third-party validation across the web, because that’s exactly what AI models are reading.
This is where partner-led growth stops being a channel strategy and becomes an AI visibility strategy. Trust with a language model can’t be purchased through ad spend. It has to be earned through independent voices.
What This Playbook Actually Teaches
Four things stand out from PartnerStack’s arc, and none of them are theoretical.
Build for customers who bring real value, not the ones who pad your sign-up count. The Base CRM near-miss proves that shallow adoption is a trap dressed up as growth.
Let the product be the distribution channel. PartnerStack didn’t outspend competitors on ads. It built a marketplace that markets itself.
Take your narrative to the boardroom. Software churns when users can’t explain its ROI to a CFO. Marketing the outcome beats marketing the mechanism every time.
Treat your partner ecosystem as your AI strategy. As buyers trust peers and language models over corporate copy, direct sales leverage keeps eroding.
A messaging app with no customers became a $3 billion revenue engine, not because the founders had a better roadmap, but because they were willing to abandon one that wasn’t working. That willingness to follow the signal, even when it contradicts the plan on the whiteboard, is the actual competitive advantage here. Most companies don’t lack the data to make that call. They lack the nerve.
