Fractional Executive Marketplace
A vetted, niche platform connecting SMBs and startups that need a part-time CFO, CMO, or CTO with experienced executives building portfolio careers, handling matching, contracts, and payments rather than just an introduction.

Market timing
Why now
The fractional model has gone mainstream, SMBs and startups increasingly want senior leadership a few days a month instead of an expensive full-time hire, and a generation of experienced operators now actively prefers portfolio careers over one employer. That two-sided demand is real and growing, but it's currently served by expensive generalist platforms, scattered LinkedIn referrals, and word of mouth, which leaves room for a vetted, niche marketplace that does the matching and trust work properly. The honest caveat is that marketplaces are the hardest model for a solo founder: you have to solve a chicken-and-egg cold start with no audience and then fight leakage once both sides meet. It only works if you go narrow enough that your curation and matching are genuinely better than a LinkedIn search.

Red Flags
ProMarketplaces are the hardest model for a solo founder, you must solve a two-sided cold start with no audience before any revenue appears.
Leakage is brutal, once a great executive and a client connect, both have every incentive to drop the platform fee and continue privately.
Trust is the whole product, one bad placement on either side can sink your reputation in a tight professional niche, so vetting can't be cut.
Competitor Breakdown
ProToptalHigh hourly rates, ~$60-$200+/hr
Broad freelance network skewed to developers and designers, not a focused, vetted home for fractional C-suite leadership.
Continuity and exec networksMembership and placement fees
Narrow or invite-only communities that don't function as an open, searchable marketplace for SMB buyers.
ParoPlacement plus percentage
Focused mainly on finance and accounting talent, leaving marketing, product, and ops fractional roles underserved.
Who it's for
Two sides: SMBs and startups that need senior expertise (a CFO, CMO, or CTO) a few days a month but can't justify a full-time hire, and experienced executives who want portfolio careers across several fractional clients.
How it makes money
Take a placement fee or an ongoing percentage of the engagement, plus optional subscription tiers for vetted access. A specific function or industry focus (e.g. fractional CFOs for e-commerce) makes matching and trust far easier than a generalist board.

How to start
1
Pick one function and one industry (e.g. fractional CMOs for B2B SaaS) so you can vet supply credibly and speak the buyers' language, niche beats broad for a cold-start marketplace.
2
Solve the chicken-and-egg by curating supply first: hand-recruit 20-30 genuinely vetted executives, then concierge-match them to demand you source manually before any software.
3
Stay in the loop on early matches by hand to learn what good fit looks like, then productize the matching and contracts once the pattern is clear.
4
Guard against leakage by owning contracts, payments, and ongoing value like vetting and dispute support, not just the introduction.

- Talk to 10 of them, ask about the problem, don't pitch. Look for real frustration.
- Collect a waitlist or take a pre-order to prove they'll act, not just nod.
- Stand up a simple site and deliver the service manually before automating anything.
- Cover the skill gaps yourself or partner up: Marketplace and two-sided growth, Web development, Vetting and matching, B2B sales and community building.
- Put it in front of 1–3 friendly early users and fix whatever confuses them.
- Pick the ONE channel that works and go deep before adding another.
- Charge from day one, even a small price validates willingness to pay.
- Track cost-per-customer vs. what each customer pays, that ratio is the business.
- Once the numbers work, reinvest in the channel that converts best.
