Your AI stack costs $4K/month. Can you prove it's working?
Most DTC founders track every ad dollar to the cent. Their AI tools? Nobody's looking. Stacklight gives you a monthly report — in plain dollars — showing exactly what each tool is worth.

The problem
You track every ad dollar. Your AI stack is a black box.
DTC founders obsess over Meta ROAS and Google CPA. The $3,000–$6,000 they spend every month on AI tools? Most have never measured any of it.
01
The invisible subscription tax
Tools adopted for old campaigns keep billing. Nobody cancels because nobody's watching. Most brands are paying for at least one tool that hasn't been opened in months.
02
No way to measure what's working
Jasper wrote your product descriptions. Did they lift conversion? Anyword generated your ad copy. Did it lower CPC? Without a measurement framework, you can't know.
03
Every vendor looks indispensable
Every tool's own dashboard tells you it's working. You need an independent view — one that applies a consistent methodology across your entire stack.
How it works
One call to set up. Then it runs itself.
After a single 55-minute onboarding call, the entire reporting pipeline runs automatically every month. You do nothing until the report lands in your inbox.

What founders discover in report one.
Illustrative examples based on real patterns found in DTC brands at these revenue stages.
"We'd had Nosto running for fourteen months. I assumed someone on the team was monitoring it. Nobody was. The first Stacklight report showed it was generating $10,700 a month — a 14x return — and that we'd never activated three of its core features. That single finding changed how we approach every tool we buy."

Nosto ROI found
"I joined as COO and looked at software spend immediately. Triple Whale and Northbeam were running simultaneously — two attribution platforms doing the same job. $1,620 a month in pure overlap. Plus a Triple Whale feature switched off costing us north of $6,000 a month in ad inefficiency. Found in week one. Fixed in week two."

"Our Gorgias Shopping Assistant had been running for three months before Stacklight looked at it. $29,000 in sales per month from pre-sale chat — completely untracked. We'd been treating Gorgias as a support cost. It turned out to be our second-highest ROI tool at 36x. We increased the budget the same week."

Common questions
Everything you need to know.
No ambiguity. Email hello@stacklight.co if something isn't answered here.
How do you access my tool data?
Read-only API keys, collected during your onboarding call. We never request admin access, billing access, or individual customer records. You can revoke access at any time.
What if some of my tools don't have an API?
Most DTC AI tools do. For the few that don't — typically creative tools like Midjourney — we use simple usage-tracking via a shared Google Sheet. Takes about 5 minutes per month.
How do you measure copywriting tools like Jasper?
Proxy metrics with agreed benchmarks. AI product descriptions lift CVR by roughly 10% on average — we apply that to your traffic and AOV. Every estimate is clearly labelled with its source.
What exactly is the free audit?
A 30-minute call. We review your stack, tell you which measurement method applies to each tool, and walk through what your first report would look like. No pitch — just useful information.
How long does setup take?
The onboarding call is 55 minutes and happens once. Your first report arrives within 30 days. After that, everything runs automatically on the 1st of each month.
Can I cancel if I don't see the value?
Yes — after the 3-month minimum with 30 days written notice. We're confident enough in what report one finds that we don't need to trap anyone.
Find out what your stack is actually worth.
30 minutes. No credit card. No commitment. We'll show you exactly what a Stacklight report looks like for your specific tools — and what we'd likely find.
From your first conversation to a monthly automated report — here is exactly what happens at every stage, and who does what.
The process
Four steps. Most of them automated.
After a single 55-minute onboarding call, the entire reporting pipeline runs without you. Every month.

The methodology
Four ways we measure ROI. One for every type of tool.
Not every AI tool can be measured the same way. We use the right method for each — agreed with you at onboarding and documented in writing.
Method 1
Direct platform data
Klaviyo · Gorgias · Nosto · Rebuy · Postscript
These tools track their own performance and expose it via API. We pull the number directly — no estimation. Klaviyo shows attributed email revenue. Gorgias shows AI-resolved tickets. Nosto shows influenced revenue from recommendation widgets.
Revenue attributed ÷ Monthly cost = ROI multiple
High precision
Method 2
Cost displacement
Copilot · Notion AI · Triple Whale · ChatGPT internal
Productivity tools save time rather than generating traceable revenue. We calculate the cost of doing the same work without the tool — using active users, hours saved per week, and fully-loaded hourly costs agreed at onboarding.
Content tools don't have direct attribution. We track output volume and apply published benchmarks — AI product descriptions lift CVR by ~10%, AI subject lines lift open rates by ~14%. Every estimate is clearly labelled with its source.
For creative tools we don't attempt ROI calculation. We track assets generated versus assets deployed in active campaigns. Two months below the agreed threshold triggers an automatic cancellation recommendation.

Case studies
What we find in real DTC stacks.
Three illustrative examples based on real patterns found in DTC brands at these revenue stages. Tools, findings, and common issues are drawn from sector research.
All company names, individuals, and specific figures are illustrative
Wren & Thread had six AI tools running and had never measured any of them. The founder asked her team which tools were working at a quarterly offsite — nobody could answer. Average order value had been flat at $87 for over a year and returns were creeping up, both symptoms of poor on-site personalisation.
↑
Nosto — 14x ROI generating $10,720/month, completely unmonitored
Nosto's attribution dashboard hadn't been opened in eight months. Personalisation widgets were generating $10,720 in influenced revenue against a $749/month subscription. Additionally, 60% of Nosto's features including personalised search and exit-intent overlays had never been activated.
!
Rebuy — Smart Cart had never been enabled
Rebuy was installed but generating only 1.6x ROI. The reason was immediately clear: the Smart Cart upsell feature — Rebuy's highest-converting placement — had simply never been switched on. One toggle. Three days after the report landed, it was live and generating $1,840 in week one.
×
Zmo.ai — $633/month for a tool unused since September
Adopted for an AI photography project that was abandoned after one test run. The subscription was never cancelled. Seven months later it was still billing at $633/month with zero assets generated. Total billed while unused: $4,431.
90-day outcome
"Nosto was generating 14x ROI for over a year and nobody on our team had looked at the dashboard. The Rebuy thing was even more frustrating — the highest-converting feature was just off. One toggle." — Cass Merriweather, Founder

Annual saving run rate
Fielding & Co's new COO joined in January 2026 and immediately looked at software spend. His first question: "We have Triple Whale, Northbeam, and Enquire Labs all running simultaneously. I think they all do attribution. Can someone explain why we need three?" Nobody could.
×
Triple Whale + Northbeam + Enquire Labs — three tools doing one job
Triple Whale and Northbeam are direct attribution competitors. Northbeam had been set up by an agency that Fielding parted ways with in mid-2024 — nobody cancelled it when the relationship ended. Total monthly overlap: $1,620.
!
Triple Whale Sonar — disabled, costing ~$6,200/month in ad inefficiency
Triple Whale's Sonar feature sends enriched first-party conversion data back to Meta's Pixel. For Fielding's $180K/month Meta spend, not having Sonar active meant Meta's algorithm was bidding on incomplete data. Conservative estimated impact: $5,800–$6,600/month. Sonar was included in their plan. It had simply never been turned on.
The Gorgias Shopping Assistant had been running for three months converting pre-sale chat into purchases. The feature had never been reviewed. The first report to include this data showed 127 completed purchases at $231 AOV — $29,337 in a single month. At 36x ROI it was immediately the second-highest performing tool in the stack.
6-week outcome
"A Triple Whale feature switched off, costing us north of six thousand a month. And a chat feature generating nearly thirty thousand in sales that nobody had ever looked at." — Marcus Okafor, COO
Haven & Rowan sells premium supplements with a strong subscription base. The brand had adopted seven AI tools throughout 2024 across marketing, content, support, and personalisation. By early 2026 the founder had no clear view of which were contributing and which were legacy from campaigns that no longer ran.
↑
Klaviyo AI — 11x ROI across email and SMS
$8,340 in attributed email revenue and $1,920 in attributed SMS revenue against a combined cost of $940/month — an 11x return. Further analysis showed four high-value automations were inactive: a subscription winback sequence, a cross-sell post-purchase flow, a replenishment reminder, and a wishlist price-drop alert. Activating all four was projected to add $4,200/month in incremental email revenue.
×
Jasper + Writesonic — $1,740/month, both underused
Haven & Rowan were paying for both Jasper ($940/month) and Writesonic ($800/month) simultaneously. Jasper was used by three team members for blog content. Writesonic was used by a single coordinator for social captions — a use case fully covered by Klaviyo's native AI copy tools already included in their subscription. Both tools were retained by different teams who didn't know the other existed.
Postscript was generating solid attributed revenue but at a declining rate. Opt-out rates had increased from 2.1% to 3.8% over three months — a signal the sending frequency was too high relative to the value being delivered. Recommendation: reduce send frequency by 30% and A/B test a value-led SMS sequence. Not a cancel — a calibration.
First report outcome
"We had two copywriting tools billing simultaneously and nobody knew. The Klaviyo finding was more important — four automations sitting inactive, projected to add over four thousand a month. Activated in a week." — Rachel Dunmore, Founder

The free audit guarantee
Every client starts with a free 30-minute AI stack audit. We show you exactly what your first report would look like. If it doesn't feel valuable after 30 minutes, you don't sign up. No pressure, no follow-up pitch.
Pricing questions
Answered.
Everything you might be wondering about cost, commitment, and cancellation.
Is the free audit really free?
Yes. Completely. 30 minutes, no credit card, no obligation. We show you what your stack looks like through our methodology and what we'd likely find. You decide whether to sign up after that.
Why is there a 3-month minimum?
Because one report tells you what's happening. Three reports tell you whether it's changing. The real value of Stacklight is in the trend — knowing that Gorgias AI resolution rate dropped from 64% to 51% between months, and understanding why. After month three you go month-to-month.
Can I change plans after signing up?
Yes. You can upgrade at any time — the change takes effect from the next billing cycle. Downgrades can be requested at any time and take effect at the end of your current month.
What if the first report doesn't find anything?
It hasn't happened yet. Every stack we've audited has had at least one finding worth acting on — usually three or four. If the first report doesn't surface something valuable, we'll extend your reporting period by one month at no charge.
Start with the free audit. Pay only if it's worth it.
30 minutes. No credit card. A clear picture of what your AI stack is actually generating.

About
Built by someone who understands the numbers.
Stacklight was started because DTC founders deserved an independent, financially rigorous view of their AI spend — and nobody was building it for them.
A
Alek Radanovic
Founder, Stacklight Analytics
I spent several years working across business operations and data analytics — roles that put me close to how companies actually make decisions about the tools and systems they run on. The pattern I kept seeing: significant spend on new technology, almost no rigorous measurement of what that technology was actually returning.
When AI tools started proliferating across DTC e-commerce in 2023 and 2024, I watched founders adopt Klaviyo AI, Gorgias, Nosto, Triple Whale and a dozen others — often on the recommendation of an agency or a conference talk — with no framework for measuring whether any of it was working.
The tools were making compelling promises. The dashboards were showing impressive-looking numbers. But nobody was asking the fundamental question: compared to what you're paying, is this actually a good return?
Stacklight is the answer to that question. A monthly report that measures every AI tool in your stack against a consistent, agreed, financially defensible methodology. Not the tool vendor's numbers. The actual return, in dollars, every month.
There's no shortage of analytics tools. There's a shortage of independent, done-for-you AI ROI reporting that doesn't require you to build or manage anything.
Independent — not a tool vendor
Every tool in your stack wants to tell you it's working. Stacklight has no commercial relationship with any AI tool provider. Our only incentive is giving you an accurate picture.
Done-for-you — not another dashboard
You don't need more dashboards. You need someone to pull the data, run the numbers, and tell you what to do. Stacklight is a monthly report that arrives in your inbox — readable in five minutes.
Methodology-first — not gut feel
Every measurement method is documented, agreed with you in writing, and applied consistently month after month. When we say a tool is generating 8x ROI, we show you exactly how we got there.
DTC-specific — not a generic tool
We built Stacklight around the specific AI tools that DTC e-commerce brands actually use. Klaviyo, Gorgias, Nosto, Rebuy, Triple Whale, Postscript. We understand their data and what good performance looks like.
How we work
The principles behind every report.
Four commitments we make to every client.
01
Transparency over precision
Not every AI tool can be measured with perfect precision. We use proxy metrics and agreed benchmarks where direct attribution isn't possible — and we label every estimate clearly. A transparent approximation is more useful than a precise-looking number with no methodology behind it.
02
Agreed inputs, consistent application
Every business input — cost per ticket, AOV, hourly rates — is agreed at onboarding and held constant month after month. Month-over-month comparisons are meaningful because you're measuring the same thing the same way every time.
03
Read-only access. Always.
We access your tool data via read-only API keys. We never request admin access, billing access, or the ability to change anything in your accounts. Every credential is stored encrypted and can be revoked by you at any time.
04
Verdicts, not just data
Data without a recommendation is just information. Every tool in your stack gets a verdict — Keep, Review, or Cut — with a single sentence of reasoning. You should be able to act on your Stacklight report within 24 hours of receiving it.
