Expertise by the slice.
Proof by the hour.

Businesses get senior, specialized people for the slice of the week they actually need. Those people serve more clients without over-promising any of them. Tesserow is the trust layer that makes both sides work — real capacity, real coverage, and every hour a record both sides can stand behind.

Why fractional works

Split a week well and both sides come out ahead.

It's one mechanism, not two separate benefits. A business can afford a specialist because it only buys the slice it needs — and the specialist can sell that slice because several businesses are buying alongside it. Tesserow exists to keep that arrangement honest enough to scale.

Senior skill, sized to the need

Most companies need a CFO's judgment, a principal engineer's eye or a real marketing lead for a few hours a week — not forty. Fractional means paying for the expertise instead of the headcount, without settling for a generalist who almost covers it.

A portfolio, not a tightrope

One client is a job with a single point of failure. Several is a business. Spreading hard-won expertise across a handful of companies turns losing one from a cliff into a dip — as long as the whole book stays visible in one place.

Room to operate like a firm

You've built a company; it should run like one. One planner across every client, hours confirmed as you work, invoices that defend themselves, and a track record that travels — the back office of a larger firm, without the larger firm.

Tesserow's cut of your rates. No broker in the middle — the relationship is yours.

Human to human. The software does the lifting.

Tesserow doesn't broker your deals or take a cut of what you charge. The relationships are yours — the ones you already have and the ones you build next. What the software does is the unglamorous part: keeping capacity honest, confirming hours as they happen, and turning the result into proof neither side has to argue about.

The problem

Fractional work runs on trust.
Trust shouldn't run on faith.

The best contributors split their week across several clients — and today, everyone involved is working half-blind.

Overcommitment is invisible

A contributor's other engagements are a black box. Nobody can see when a week quietly promises more hours than it holds — until deadlines slip.

Timesheets are just claims

Hours get reconstructed at month-end and taken on faith. When questions come up, the answer is an awkward audit, not a clear record.

Track records aren't portable

Years of dependable delivery live in scattered invoices and other people's memories. None of it travels with the person who earned it.

How it works

Build on trusted hours

Three habits, one shared source of truth.

1

Plan real capacity

Contributors lay out their week across every client in one planner. Commitments stay inside the hours that actually exist — no silent double-booking, no over-promised weeks.

2

Work with confirmation

Hours are recorded as work happens and confirmed by both sides along the way — not reconstructed from memory when the invoice is due.

3

Keep the proof

Every engagement builds a consistent, checkable record — planned, delivered, approved, invoiced — without exposing anyone's client list to anyone else.

Illustrative example — this is what a month looks like when nothing is taken on faith.

For contributors

Your time, defended.
Your reputation, portable.

  • A schedule that guards your limits — set your true capacity once; every new commitment is checked against it.
  • Standing that travels — your confirmed hours build a professional record you can share as proof, with any client, anywhere.
  • Invoices tied to approved work — billing flows from hours both sides already agreed on, so payment conversations stay short.
  • Your existing clients, from day one — start with the book you already have and begin planning today. When your clients join to confirm hours, the shared record starts building for both of you.
  • We never take a cut — keep your clients, keep your rates. Planner, hours and invoices from approved work are free. Companies pay for the coverage view and the audit trail.
  • Privacy by design — your clients never see each other. Proof of reliability never means exposing your book of business.
For businesses

Coverage you can see.
Records you can check.

  • Real coverage at a glance — know what your fractional team has actually committed to you, this week and next.
  • Budgets that hold — set spending guardrails per engagement; approvals route to you before the line is crossed.
  • Approvals, not audits — confirm work as it lands: one tap, in minutes. Month-end stops being an investigation.
  • Bring the people you already trust — start with your current contractors; no re-hiring, no disruption.
  • Specialists, not a staffing pool — you work with the exact person you chose. Tesserow never steps into the relationship.
  • What you pay for — coverage you can see and a record you can check, with every invoice reconciling back to the confirmed hours behind it. Confirming is always free; the system of record is the product.
Verified time, every hour

VeriHour — a verified record of professional time.

Every confirmed hour on Tesserow strengthens a contributor's VeriHour standing: how much time was declared, delivered, and verified by the businesses it was delivered to. It's proof of reliability that can be shared and independently checked — without revealing who the work was for.
