Six years ago, BigCommerce was the credible number two to Shopify in ecommerce software. Not a niche player. The only standalone, pure-play public alternative to Shopify that a public market investor could buy. It was more B2B but worryingly, wasn’t growing faster on a percentage basis from a smaller base. Meritech’s IPO breakdown in July 2020 called them “a very distant #2,” and that was the bull case. Everyone else in the category was a division of something bigger: Magento inside Adobe, Commerce Cloud inside Salesforce, WooCommerce inside Automattic.
Intuit offered $1.5B for the company about a month before the IPO. BigCommerce turned it down and went public instead, priced at $24, closed the first day at $72.27, and became the biggest IPO pop of 2020 at a roughly $4.8B market cap.
Today the company is called Commerce.com, trades under CMRC at roughly a $200M market cap (less than 1x ARR), is fielding a hostile bid from a much smaller company, and just guided full-year 2026 revenue to a midpoint below what it did in 2025.
Everyone knew Shopify was winning back in 2020. What’s useful now is the shape of the decay, and what it says about what compounds in B2B.
Today it trades at 1x ARR and is so far behind as to be almost … irrelevant:
- The revenue gap went from 19x in 2020 to roughly 44x on this year’s guidance. Second place didn’t hold. It decayed in six straight years.
- Shopify’s growth rate barely moved over that span, holding 26% to 30% at $11B+ in revenue. BigCommerce went 36%, 44%, 27%, 11%, 7%, 3%, and now negative.
- BigCommerce’s merchandise volume is still growing 14%. Its subscription revenue is shrinking 1%. They have the volume and can’t convert it.
- Shopify takes 78% of its revenue from transactions. Commerce takes 75% of its revenue from subscriptions. Same market, opposite models, and the transaction model won by roughly 40x.
- The defensible niche didn’t hold either. B2B was BigCommerce’s chosen wedge. Their B2B volume grew 17% last quarter. Shopify’s grew 76%.
The Tough Learnings:
1. Second Place Was Real, and It Decayed Every Single Year
The revenue gap, side by side:
From 2020 through 2022 the gap sat flat at around 20x. For two years it really did look like a market with room for two winners, which is what nearly everyone said at the time. Then it opened up every year after. The gap didn’t widen because BigCommerce collapsed. It widened because BigCommerce went from 27% growth to 11% to 7% to 3% while a company twenty times its size held 26% to 30%.
There was no disaster quarter here, at least not for a while. No breach, no failed platform migration, no scandal. Deceleration did all of the work.
2. Growth Rates Are the Whole Story
{“model_id”: “unified-v1/prod/20260814-205114”}
- In 2021, BigCommerce grew 44% and Shopify grew 57%. Close enough to be a race.
- By 2023 it was 11% versus 26%. By 2025, 3% versus 30%. The 2026 guide of $336.5M to $344.5M puts the midpoint under the $342.3M they did last year, so the company that grew 44% five years ago is now guiding to flat-to-down.
Shopify went the other way and accelerated at scale. 2025 revenue growth of 30% was four points higher than 2024. Q2 2026 came in at 34%. That’s roughly $900M of incremental quarterly revenue, about 2.7x Commerce’s entire annual revenue, added every three months.
Growth rate at scale is the most predictive metric in B2B, and six years of it is what you’re looking at in that chart.
3. What Actually Broke: They Sold Software, Shopify Sold the Transaction
- Q2 2026 for Commerce: GMV up 14% to $8.8B. Subscription revenue down 1%. Total ARR $360.5M, up 2%. Net revenue retention 95.8%, the best it’s been in three quarters and still low enough that the base shrinks every year before new logos.
- Q2 2026 for Shopify: GMV up 32% to $115.6B, revenue up 34%. Revenue grew faster than volume, because Shopify Payments hit 68% of total GMV, up from 64% a year ago. Merchant solutions is now 78% of Shopify’s revenue at $2.9B a quarter. Subscription is 22%.
Commerce is the mirror image. Subscription solutions were $63.1M of the $84.5M quarter, about 75%.
Merchandise flows across both platforms. Shopify gets paid more as that merchandise grows, and BigCommerce gets paid the same whether a merchant does $1M or $50M. Six years of compounding on that one choice is worth about 40x in revenue and about 1,000x in market cap.
Commerce’s CFO named this on the Q2 call as the priority: closing the gap between GMV growth and revenue growth through payments, cross-sell and attach. They shipped BigCommerce Payments with PayPal this year and said volume is running more than 30% ahead of internal plan. It’s the right fix, arriving about six years after Shopify made it the center of the model.
4. The Niche Didn’t Save Them
The standard advice for a distant number two is to pick a defensible segment and own it. BigCommerce did exactly that. They went enterprise and B2B, built the more open architecture, and won the feature comparisons. They took 24 out of 24 medals in the 2026 Paradigm B2B Combines, the fourth straight year.
The scoreboard on that strategy:
- Commerce B2B GMV last quarter: up 17%.
- Shopify B2B GMV last quarter: up 76%.
- Enterprise ARR is 80% of Commerce’s total ARR, up from 75% a year ago, and enterprise account count was down 2% year over year as of last fall, with average revenue per account up 7%.
Revenue per account rising while account count falls is price capture on a shrinking base. It works for a few years and then it stops.
Winning the analyst scorecard in a segment while the leader grows that same segment four times faster isn’t a defensible niche. It’s a slower loss with better marketing collateral.
5. The Market Has Already Priced All of This
- In August 2020, Shopify was worth about $120B and BigCommerce about $4.8B, a 25x spread.
- In August 2026, Shopify is worth about $204B and Commerce about $200M. Call it 1,000x.
The company has done nearly everything the playbook says to do when growth stalls. New CEO. Rebrand from BigCommerce to Commerce.com. Workforce realignment explicitly driven by AI and automation. Two consecutive quarters of positive GAAP net income. Q2 non-GAAP operating income of $8.1M against guidance of $4M to $5M. The cost discipline and margin expansion are real.
The stock fell anyway on the Q2 print, because the same release cut full-year revenue guidance by $18M at the midpoint. Analyst price targets sit in the $3.00 to $3.50 range at Barclays and UBS. Rezolve AI, a company a fraction of Commerce’s size, launched a hostile bid, and its CEO went on television and called the growth rate embarrassing.
Profitability doesn’t fix a growth problem. It buys time to fix one, and the market prices those two things very differently.
6. What This Means If You’re Not Number One
Most B2B companies aren’t number one, and that’s fine. Second place just isn’t a moat. It only holds if you’re growing at least as fast as the leader.
Five things to take from it:
- Your monetization unit matters more than your feature set. BigCommerce built the more open, more flexible platform and won the enterprise B2B feature comparisons four years running. Shopify built a business that captures a percentage of what its customers sell. Six years later the feature winner is worth 1/1,000th of the monetization winner.
- Compare your growth rate to the leader’s, not to your own last year. BigCommerce grew 44% in 2021 and it looked great. Shopify grew 57% at twenty times the size. That was the signal, and it was visible in their first year as a public company.
- A 95% net revenue retention rate is a countdown clock. The installed base shrinks every year, so all growth has to come from new logos, in a category where the leader compounds faster than you can acquire.
- Deceleration is a slow-motion event and it’s entirely visible. 36, 44, 27, 11, 7, 3. Nothing in that sequence was a surprise on the day it printed. The whole story was legible by 2023. Being early on your own bad news is the only way to keep options.
- Turning down $1.5B is a decision with real downstream impacts. Intuit’s offer was roughly seven times what the entire company is worth today. Going public wasn’t obviously wrong at the time. It became wrong because the growth rate didn’t hold, which is the only thing that ever justifies the choice.
What Second Place Actually Costs
Shopify and BigCommerce saw the same market at roughly the same time with roughly the same product surface, and both were right that ecommerce was going to be enormous. Shopify built a model that gets paid when merchants grow. BigCommerce built a model that gets paid when merchants sign up.
The market was big enough for two companies. It wasn’t big enough for two business models.
