A second brainfor founderswho wear three hats.

Xn indexes your Finance, Customer, and Communication. It replays what matters at the right moment and ignores the rest. You pay us nothing if we don't shorten your time from signal to decision.

  01 / Problem

Three brains. One head.

Multi-hat founders don't fail by being lazy. They fail by context-switching. Signals arrive at one hat that should have triggered a different hat. The miss happens in the gap.

This isn't burnout. It's memory load. The brain wasn't built to index three role-graphs at once.

Hat 01
CEO of your own shop.

AR collections, payroll, hiring, vendor management. Your own franchise tax filing nearly slipped, six days before the deadline.

Signal source · Accounting · Banking
Hat 02
Fractional CFO for six clients.

Three SaaS, two DTC, one healthtech. Each with their own burn, runway, board cadence, accounting tool. Each Monday at 10:01am someone Slacks "look at our burn."

Signal source · 6 stacks · Slack · Board
Hat 03
Marketer for everything.

Own LinkedIn, own newsletter, content for two client engagements. The growth experiment running right now needs a read-out you keep forgetting to write.

Avery Mercier, 38
Founder · Fractional CFO · Marketer · Austin, TX

"Six weeks ago I nearly missed Texas franchise tax for my own company. Same week I missed a board-prep ask from a client CEO. I stopped sleeping for a week."

  02 / Foundation

The FCC.

Three signal pillars. All three are mandatory. Anyone unwilling to grant access to all three is not a customer.

Before anyone asks — yes, this is invasive. That's the point. We can't compute your baseline from a sanitized export. We need the archive.

F

Finance

QuickBooks · Mercury · Brex · Gusto · NetSuite

Accounting + banking + payroll. Per-client and per-company. We see runway, burn, AR aging, payroll cadence, tax deadlines.

C

Customer

HubSpot · Salesforce · Attio · Pipedrive · Notion

CRM + deal flow + client engagements. Who's at risk, who's overdue for a touchpoint, who just signed.

C

Communication

Slack · Gmail · Signal · iMessage · Telegram

Including 90 days of history. This is how we derive your baseline. Not what you tell us. What you actually did.

No FCC, no Xn.   If you won't open your archive we can't compute your baseline, and we can't get paid. We are happy with that filter.

  03 / Architecture

A second brain, not a wrapper.

Every product decision points to a named memory function with a citation. We don't replace your tools. We index them. Long-term storage stays where it lives — Xn replays what matters when it matters.

Vannevar Bush, 1945. Look up the memex.

Encode
Bind time, person, topic, outcome into one episode.

"ClientCo Tuesday call, runway question, action: send Q3 cash plan by Friday." Atomic memory unit.

CA1 · episodic encoding
Pattern-separate
Disambiguate signals that look alike.

Client A's burn alert is not Client B's burn alert. Different runway, different stage, different next move.

Dentate gyrus · pattern separation
Index
Plug into the tools you already use.

QuickBooks, Mercury, Gusto, HubSpot, Notion, Slack. We never ask you to switch. Indexing theory, not replacement theory.

Teyler & DiScenna · 1986
Replay
Nightly distillation of what mattered.

6 AM digest: Client A invoiced. Client B burn up 12% MoM. Client C payroll tax due in 6 days. Read it with coffee.

Sharp-wave ripples · consolidation
Pattern-complete
One cue surfaces the whole memory.

"ClientCo" → balance, burn, runway, last board notes, next ask. The bundle, on demand, before the call.

CA3 · pattern completion
Fire signal  ·  F

A client's burn just jumped 18%. Your call with their CEO is in 47 minutes. What happens next?

Avery, six weeks ago
4.2hrs
signal → decision

Four tabs. Twenty minutes to even reconstruct context. Reply at 4 PM, after the call already happened.

Avery, with Xn
47sec
signal → decision

Alert fires unprompted. Draft cash-runway brief streams. Three options, one recommendation. Click "send."

That delta — 4.2 hours to 47 seconds — is the number we charge against.

  04 / Pricing

Pay only when the metric moves.

We earn on customer success.

Three phases. Same promise: you don't pay until the metric moves.

No baseline games. No platform floor. Day 0 is on us. Day 30 we share what we lifted. Day 90 we lock the relationship — but only if the ROI is real.

Day 0–7
0$

Proof phase.

Day 30
+ 5% upside

Value-share kicks in.

Day 90+
Annual prepay

Once ROI is real, customer locks 12 months. Quarterly review baked in.

We're showing this at Berlin Hackathon today.

It's a working build, not a deck. Open the chat, drop a question your three hats keep dropping, watch Xn route it. Or run the 12-minute onboarding and leave with your Signal Triage Profile in hand — whether you buy or not.
