AT A GLANCE
FUNDING HISTORY
Tropic
BUSINESS MODEL
Tropic
Tropic charges an annual subscription based on the customer's software spend under management. The platform pays for itself through savings — if Tropic helps a company save $500,000 on software renewals, the subscription cost is a fraction of that.
Some pricing includes a success fee tied to actual savings achieved.
The value proposition is mathematically clear: Tropic typically saves customers 23% on their SaaS spending. For a company spending $5 million annually on software, that's $1.15 million in savings.
Tropic's subscription fee is a small percentage of those savings, making the ROI calculation trivially obvious.
The data moat grows with every customer. Each contract that flows through Tropic adds to their pricing benchmarks database, making their negotiation intelligence more accurate for future customers.
This is a classic network effect — the more companies use Tropic, the better it works for everyone.
Pinterest makes money through advertising — specifically through "Promoted Pins" that look nearly identical to organic content. This is the magic of Pinterest's business model: ads don't interrupt the experience because the experience IS discovering products and ideas.
A promoted pin for a kitchen knife set appears right alongside organic pins of kitchen designs. The user doesn't distinguish between "ad" and "content" because both serve the same purpose.
Shopping ads are the fastest-growing segment. Brands upload their product catalogs, Pinterest matches products to user searches and boards, and users can buy directly through the platform or click through to the retailer's site.
Pinterest gets paid per click or per thousand impressions.
Revenue reached $3.65 billion in 2024, up from $3.05 billion the year before, and 2024 was its first genuinely profitable year. Average revenue per user is growing but still well below Meta's — the upside is enormous if Pinterest can close that gap.
HOW THEY STARTED
Tropic
David Campbell spent years in SaaS sales and noticed something absurd: companies buying software almost never negotiated. They'd receive a quote, maybe push back slightly, and sign.
Meanwhile, the vendor knew exactly what discount they could offer because they had data from thousands of deals. The information asymmetry was massive — and it always favored the seller.
Campbell founded Tropic in 2020 to flip that asymmetry. The core insight was that if you aggregate pricing data from thousands of SaaS contracts across hundreds of companies, you can tell any buyer exactly what fair market price looks like.
Basically, "Company X is charging you $50 per user for this tier, but companies your size typically pay $32." That data-driven approach turns every negotiation from guesswork into science.
The timing was perfect. Post-COVID, companies were drowning in SaaS subscriptions.
The average mid-market company uses 100-200 software tools. CFOs started demanding visibility into software spend, and finance teams had no tools to manage it.
Tropic stepped into that gap with a platform that combined procurement automation with AI-powered negotiation intelligence.
Ben Silbermann was a former Google ad operations employee who quit in 2008 to build apps. His first attempt was an iPhone app called Tote — essentially a mobile catalog that let women browse and bookmark products from fashion retailers.
Nobody downloaded it. But Silbermann noticed something in the data: users were saving products obsessively.
The collecting behavior was more interesting than the shopping behavior.
He teamed up with Paul Sciarra, a classmate from Yale, and Evan Sharp, a designer who was studying architecture at Columbia. Together they built Pinterest — a visual bookmarking tool that let people "pin" images from around the internet to organized boards.
Think of it as a digital mood board that anyone could make.
Pinterest launched as an invite-only beta in March 2010. Growth was painfully slow at first.
Silbermann personally wrote to the first 5,000 users, giving them his phone number and asking what they wanted. The early community was overwhelmingly women interested in home decor, fashion, recipes, and DIY projects.
By 2011, Time magazine named Pinterest one of the 50 best websites. By 2012, it was the fastest site in history to reach 10 million unique monthly visitors.
HOW THEY GREW
Tropic
Tropic grew by selling to CFOs with a message they couldn't resist: "we will literally save you more money than we cost." In a market where every other tool adds to the tech stack cost, Tropic reduces it. That positioning is powerful during economic downturns when CFOs are cutting budgets.
Customer success stories spread quickly. When a finance leader saves $500K on software renewals using Tropic, they tell other finance leaders.
The procurement community is tight-knit, and word travels fast at CFO conferences and finance Slack communities.
The managed services component creates stickiness. Tropic doesn't just provide data — their negotiators handle the actual vendor conversations.
This "done for you" model means customers don't need internal procurement expertise. Once Tropic handles your renewals, bringing the function in-house again feels like a downgrade.
Pinterest grew organically through women sharing boards with each other. The weddings use case was the killer app — brides-to-be would create boards for dresses, venues, flowers, and invitations, then share them with their wedding parties.
That viral loop drove millions of signups.
SEO is the secret weapon. Pinterest pages rank extremely well in Google Image Search.
Someone searching "modern living room ideas" often sees Pinterest results on page one. That drives a large stream of organic traffic from people who were not looking for Pinterest at all.
Unlike other social platforms, which compete with Google for attention, Pinterest quietly benefits from it.
The shopping pivot has been the growth unlock. Under CEO Bill Ready (former Google and PayPal executive who took over in 2022), Pinterest aggressively invested in shopping features — catalog integrations, buyable pins, merchant verification, and visual search for products.
The thesis: Pinterest users are already in a shopping mindset, so removing friction between "I like this" and "I bought this" is the straightforward path to revenue growth.
THE HARD PART
Tropic
The procurement software market is getting crowded. Vendr, Zylo, Productiv, and Sastrify all target SaaS spend management from different angles.
Differentiation is challenging when every vendor claims to save customers money on software purchases.
Scaling the negotiation services team is operationally complex. Unlike pure software companies that scale with zero marginal cost, Tropic's managed negotiation service requires trained humans.
Each new customer needs real people conducting real vendor negotiations. Balancing human-led services with AI automation is an ongoing challenge.
Vendor pushback is real. As procurement platforms become more common, SaaS vendors are adjusting their pricing strategies to account for aggressive negotiation.
Some vendors have started offering "non-negotiable" pricing tiers or adjusting discount structures. The more successful Tropic becomes, the more vendors adapt their tactics.
Pinterest's demographics are both an advantage and a limitation. The platform skews heavily female (over 60% women) and is strongest in home, fashion, food, and weddings.
Expanding beyond these categories to attract male users, younger demographics, and different use cases has been slow.
Competition for ad dollars is fierce. Pinterest competes with Meta, Google, TikTok, and Amazon for advertising budgets.
Most advertisers allocate the bulk of their spend to Meta and Google first, then consider others. Pinterest needs to prove its return on ad spend is competitive to win larger budget allocations.
Creator economy is underdeveloped. While Instagram, TikTok, and YouTube have massive creator ecosystems with monetization tools, Pinterest has historically been about content discovery, not content creation.
Users pin other people's content — the original creators often don't even know their work is on Pinterest. Building a creator program and driving original content creation on the platform has been a recent focus but lags far behind competitors.
