Every business gets a bench of experts.
Every expert gets a book of clients.
A bench of experts.
Without the payroll.
- Specialists on call, backups lined up. A CFO, a designer, an engineer: keep the people you trust on a bench, a primary and a backup for every role, in the order you'd call them. When someone is full or a new need comes up, you're not starting from scratch.
- Pay for the hours the work needs. Senior expertise without a full-time salary, and without retainer hours that go unused.
- Room to add who you don't have yet. List an open role and hear from professionals who already work this way. Nobody arrives with a résumé; they arrive with hours their clients signed. No finder's fee, no cut.
- Know the cost before you ask. Every request arrives priced and checked against available hours. Budgets are visible as you go. No surprises at invoice time.
More for businesses
- Real coverage at a glance. Know what your fractional people have actually committed to you, this week and next. An hour committed to you can't be committed to anyone else.
- Approvals, not audits. Confirm work as it lands: one tap, in minutes. Month-end stops being an investigation.
- A bench, not a gig. Start with the contractors you already trust; no re-hiring, no disruption. You work with the exact person you chose, and 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.
- Agents welcome, signatures human. Your professionals can let an AI agent do the routine work; approving hours stays with a person, and the trail shows when an agent acted. How it works
We're onboarding early partners by hand. Bring the contractors you already work with.
Talk to us about your benchA book of clients.
Not a single job.
- Get found by companies that already work this way. List a profile in the Directory, where businesses that keep benches of fractional people look. When a client countersigns your hours, your card reads On record.
- More clients, less admin. Every client in one planner, hours approved with a tap, invoices built from approved work. The back office of a larger firm, without the larger firm.
- An hour can only be sold once. Set your true capacity once; every new commitment is checked against it, and hours committed to one client can't be committed to another.
- Boundaries without awkward conversations. Hour caps and budgets hold on their own, so nobody has to be the one who polices them.
More for professionals
- Your record goes with you. Your confirmed hours build a verified track record that travels to every future client. Nobody arrives with a résumé. They arrive with a ledger.
- 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. Core tools are free for professionals. 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.
- Bring your own AI agent. Connect any MCP-capable agent to plan your week, log your hours and draft invoices on your behalf. It proposes; you sign. Tesserow for agents
A profile takes five minutes. List it in the Directory when you're ready; professionals never pay.
Create your profileThree steps, one shared record.
Agree once, then just work. Nothing to reconcile at month-end.
Set the terms once
Rates, weekly budgets, hour caps and dates go into Tesserow and both sides confirm them. Your written agreement still sets the lines; Tesserow keeps them, so nobody rereads the PDF.
Work, and approve as you go
Hours are recorded as the work happens and the business approves them with one tap. Every commitment is checked against the professional's real week, so an hour committed to one client can't be committed to another.
The invoice already matches
Billing comes from hours both sides approved, and every line traces back to them. The record builds itself (planned, delivered, approved, invoiced) without exposing anyone's client list.
Illustrative example: this is what a month looks like when nothing is taken on faith.
The short answers.
Is this really how people work?
More and more. Plenty of companies already rely on a part-time CFO, bookkeeper, designer or engineer, and plenty of professionals serve three or more clients at once. Today that runs on a PDF, a spreadsheet and good faith. Tesserow gives it a proper home.
How is this different from a hiring site?
Hiring sites help you find a stranger, and many take a cut of every hour. Tesserow is where you work with the people you already trust, and where businesses and professionals who work this way can find each other. No bidding, no finder's fee, no cut of anyone's rate.
Do we still need a written contract?
Keep your agreement for scope, IP and the legal terms. Tesserow holds the numbers from it: rates, weekly budgets, hour caps and dates. Both sides confirm them once, then work inside them. Each side stays responsible for its own agreement and compliance.
Will it stay in line with our actual contract?
You enter the terms once and both sides confirm them, so the record matches what you agreed. Hour caps and end dates hold on their own, weekly budgets are flagged as you go, and changing the terms means new terms both sides confirm.
What does the business get?
Specialists on call with backups lined up, the cost of a request before you make it, and invoices that trace back to hours you approved. Confirming hours is always free; businesses pay for the coverage view and the audit trail.
What does the professional get?
More clients without more admin, invoices nobody disputes, boundaries that hold without awkward conversations, and a track record that travels to every future client. Free for professionals, and we never take a cut.
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.
Contracts were written for a world where work was invisible.
Retainers guess at the hours. Terms sit in a PDF nobody rereads. The real cost shows up at invoice time. Tesserow tracks the work as it happens, so the relationship can flex with it.
Agree once. Then just work.
The contract sets the lines. Tesserow keeps them.
Rates, weekly budgets, hour caps and dates live in Tesserow, so both sides work inside the terms without rereading the agreement. The work itself stays between you.
Proof over paperwork.
Stop paying for the guess.
Hours are the proof. Outcomes are the point. Every hour is signed by the person who worked it and confirmed by the business that asked for it, and the record carries the trust from there.
The number of US professionals working fractionally roughly doubled between 2022 and 2024.
Industry forecasts put at least one fractional leader on retainer at roughly a third of midsize companies by 2027.
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.
Industry figures are directional estimates from published market research (FRAK, The State of Fractional Report, 2024; 2027 forecast as widely cited in industry coverage).
Fractional work runs on trust.
Trust shouldn't run on faith.
The best professionals split their week across several clients, and today everyone involved is working half-blind.
Overcommitment is invisible
A professional'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.
VeriHour: a verified record of professional time.
Every confirmed hour on Tesserow strengthens a professional'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.
VeriHour by Tesserow
Proof without surveillance
No screenshots. No activity scores. Two people agree on every hour, and that agreement is the record.
Audit-ready by default
A signed, tamper-evident record of every approved hour, ready to export when an auditor or your board asks.
Your record goes with you
Professionals build a verified track record that travels to every future client. Nobody arrives with a résumé. They arrive with a ledger.
Let AI handle the routine. People still sign.
Connect your AI assistant to plan the week, log hours and draft invoices. It can propose. Only a person can confirm, and the record shows which was which. Tesserow for agents
Make fractional work easy to run.
Tesserow is onboarding a small group of early partners: professionals who juggle multiple clients, and businesses that build a bench of fractional people.
