We find the problems in your business before they cost you money.

Tell us what keeps you up at night. Sereno connects to your entire stack, figures out everything that can go wrong, and watches the things that matter, including the ones you didn't think to look for. Set up in days. No data person required.

We'll show you Sereno catching a real problem on your actual data. No slides.

Your team is fighting fires. Not building the business.

A product was underperforming for three weeks before anyone noticed. Something changed in Shopify and quietly broke your revenue numbers. Your CAC spiked on Tuesday but nobody flagged it until the Friday meeting. A vendor switch shifted your margins and the spreadsheet didn't update.

These aren't edge cases. This is every week.

The dragon that was small on Monday is burning the house down by Friday. Every fire you fight is time you're not spending on growth, strategy, or the things you actually hired people to do.

Sereno stops the firefighting.

Weve seen these fires before.

Not in theory. In real FMCG businesses running on Shopify, Amazon, and fifteen other tools.

The supplier cost increase that ate your margins for three weeks because nobody cross-referenced the invoice with the pricing sheet. By the time finance caught it at month-end, you’d shipped 4,000 units at a loss.

The GA4 tracking gap that made your email look 34% worse than it was. Your team cut email budget based on bad data. Revenue dropped. Nobody connected the two until Q2 review.

The SKU that was propping up your entire P&L and nobody noticed until Amazon delisted it for a catalog compliance issue. The 48 hours between delisting and reinstatement cost more than the previous month’s ad spend.

The Prime Day inventory miscalculation because your 3PL’s data had a 6-hour lag and your demand forecast was using stale numbers. You sold out of your top 3 products by 2 PM on day one.

We built Sereno because we lived these problems. We know exactly where they hide. And we built a system that watches for them so your team doesn't have to.

Three steps. No data person. Usually done by Friday.

You tell us what you care about. We figure out what to watch, develop our own judgment about your business, and surface the problems that matter, including the ones you didn't think to look for.

Every tool you use. Including the weird ones.
Shopify, Amazon, Meta, your Postgres, the FTP drop your 3PL sends nightly. If your data lives somewhere, we read it.
02
Listen
A conversation about your business, not your data.
What do you need to sleep at night? Revenue protection? Margin health? Inventory coverage before Prime Day? You tell us what you care about. We go figure out everything underneath: every metric, every dependency, every fragile point. Then we come back with what we think is critical. You agree, adjust, or tell us we’re wrong. That’s the starting point.
03
Watch
Including the places you didn’t think to look.
Sereno monitors your business 24/7 with its own judgment about what matters. When something starts drifting, whether a margin shift, a revenue leak, or a trend break, you hear about it before it becomes a crisis. But it also catches things you never asked about: the SKU that’s quietly becoming your biggest risk, the supplier cost change nobody reflected in the pricing sheet, the channel that’s underperforming relative to brands at your stage. It tells you what it found, why it matters, and what to do about it.

The problems we catch before you think to ask.

You told us you care about margins. You didn't tell us to watch Turmeric Latte specifically. You didn't set up an alert for supplier cost changes. You didn't configure a threshold for SKU-level margin drift.

Sereno figured out that TU-018 is one of three products holding up 68% of your gross margin. It started watching it on its own. When the supplier cost increase hit, Sereno caught it in 48 hours. Your team would have found it at month-end close. Three weeks later, $8,400 poorer.

# alerts
Sereno7:42 AM
Margin anomaly: Turmeric Latte (TU-018).

Gross margin on TU-018 dropped from 42% to 31% over the last 8 days. Traces to a supplier cost increase on Feb 6 that wasn't reflected in your pricing sheet.

At current volume, this is costing you ~$2,800/week.

Auto-generated. You told us you care about margins. Sereno identified TU-018 as a critical margin driver and began monitoring it on day 3.

Applying your definition. Meta + Google + TikTok, influencer spend excluded, 5-day agency lag.

And when you do ask, the answer is the same.

Every answer traces back to the same judgment that drives the alerts. Dashboard, Slack, Sheets. One number, not three.

Every problem caught makes the next one easier.

Sereno gets sharper the longer your team runs it. Every problem caught, every call corrected, every piece of context picked up, stays with the business.
Day 30
Sereno tells you things you didn’t know about your own business.

“We identified that 3 of your 47 SKUs account for 68% of your gross margin. If any of them dip below a 35% margin threshold, your overall profitability flips. We’ve set up monitoring on all three.” You didn’t ask for this. You said you care about margins. Sereno figured out the rest. The firefighting is already slowing down, because someone is finally watching.

Day 90
Sereno starts having opinions.

“Last time your Meta CPM was this high, it corrected within a week. We’re watching but not escalating yet.” “Brands in your category typically see a subscription churn spike 90 days after the first promotional acquisition wave. Yours is in 2 weeks. Here’s what the ones who retained well did differently.” Sereno isn’t just monitoring anymore. It’s making judgment calls: what to escalate, what to watch, what to ignore. And those calls are getting better every day based on your team’s feedback.

Day 365
A new CFO joins and asks Sereno first.

The business has changed. New channels, new products, new team members. Sereno changed with it. A year of judgment sits behind every alert: which problems mattered, which were noise, how this team makes decisions. When someone in the meeting pushes back on a number, Sereno doesn’t just remember the number. It remembers the decision, the context, and the outcome. The institutional wisdom stays, even when the people don’t.

The smartest person in every room.

Every company has one. Not the most senior. Not the loudest. The one who's been there long enough to know why things are the way they are. When someone proposes a new supplier, they're the one who says “we tried a cheaper supplier in Q3 last year. Lead times doubled and we lost $40k in stockouts.” When the CEO asks why margins are down, they don't look at a dashboard. They already know.

They make better decisions because they carry 18 months of context that nobody else has. They know which SKUs are load-bearing. They know which ad creative performs in January but dies in March. They know that the Meta pixel breaks every time Shopify pushes an update, and they know to check it before the Tuesday report goes out.

That person is also your single point of failure. When they leave, the context leaves with them. When they're on holiday, decisions get made blind. When the business outgrows one person's ability to track everything, the gaps start costing money and nobody can explain why.

Sereno is that person, multiplied across every part of the business, awake 24/7, and getting sharper every day.

But Sereno goes further than any single person can. Because it also carries the wisdom of every other brand it works with. A veteran operator at your company might have three years of context about your business. Sereno has context from hundreds of businesses in your category. It knows that brands at your stage typically see margin compression when they cross 200 SKUs. It knows that Prime Day prep needs to start six weeks earlier than most operators plan for. It knows which metrics are early-warning signals for churn in subscription-heavy FMCG.

Institutional memory is remembering what happened. Institutional wisdom is knowing what's about to happen. That's what you're buying.

Dashboard tools (Triple Whale, Polar, etc.)
Show you what happened yesterday. Don’t tell you what’s about to go wrong. Use their definitions, not yours. Break when schemas change.
Generic AI on your data (Menza, ChatGPT, etc.)
You tell it what to track. It tracks. No judgment about what you should be tracking. Doesn’t discover what you didn’t think to look for. Alerts are templates, not opinions.
An in-house analyst
Catches problems, when they have time. Knows your business, until they leave. Every new question is a new ticket. Every fire takes them off strategy work.

Questions before the call.

If something isn't here, ask us on the call. We'd rather you bring the hard ones.
Silent changes in your tools that break the numbers you report on. Revenue leaks from supplier cost increases nobody noticed. CAC spikes traced to specific campaigns. Margin compression from pricing that didn't update. Inventory trends heading toward stockouts. Email performance being undercounted because of a tracking gap. Anything that's costing you money and that your team doesn't have time to monitor manually.
Sereno is built for consumer brands between $5M and $100M in revenue that use five or more data sources and don't have a dedicated data team. If your team spends more time reconciling numbers and firefighting data problems than making decisions, Sereno is built for you. If you're a small Shopify store with a couple of tools, or you already have a data team that owns your warehouse, Sereno isn't for you yet.
With those tools, you tell them what to track and they track it. You build the alerts. You configure the thresholds. You decide where to look. With Sereno, you tell us what you care about, whether revenue, margins, or growth, and we figure out everything underneath. We discover which products are critical to your P&L, which channels are fragile, which metrics are early-warning signals. Then we set up monitoring ourselves, tell you what we found, and start watching. You approve, adjust, or tell us we’re wrong. Over time, Sereno develops judgment specific to your company: what to escalate at 6 AM and what can wait until Monday. The difference: they watch where you point them. We figure out where to look.
When you first onboard, Sereno discovers what matters in your business based on your data and your priorities. It forms an opinion: these are your critical metrics, these are your risk areas, these are the things I’d watch. You validate that opinion. Over time, as Sereno catches problems and gets your feedback on what mattered vs. what was noise, it develops judgment specific to your company. After 90 days, it knows the difference between a blip and a crisis for your business. After a year, it knows how your team makes decisions. That judgment is the product.
Days, not months. Standard tools connect in minutes. Custom or legacy sources take a day or two. The conversation where you tell us what matters happens in week one. Most teams are catching their first problems by Friday.
SOC 2 in progress. Early design partners operate under mutual NDA with enterprise-grade security terms. Your data stays in your environment. We read from your warehouse and sources. We don't move it into ours.
That's usually the reason people come to us. Custom Postgres, a legacy ERP, a subscription engine your old team built in 2019, an FTP drop from your 3PL. If your data lives somewhere, we read it. New sources take a day or two.
No. The whole point is that you don't. Your finance and growth leads approve definitions in plain English. Sereno does the watching. Your team gets the alerts. No SQL, no metric configuration.
The 15-minute demo runs on your actual data. We'll show Sereno catching a real problem before you've signed anything. If you want to go further, we start with a pilot. We're intentionally demo-led while we're still learning what the product needs to be.
Sereno starts at $5,000/month. That includes setup, onboarding, continuous monitoring, proactive alerts, and full access to dashboards, Slack integration, and Sheets. For context, the average problem Sereno catches costs more than a month of the subscription.
An AI that answers when you ask is a tool.
An AI that knows what to ask before you do is something else entirely.
We built the second kind.
