A few clients, not a book of business.
Three to seven CEOs at a time, never more. If Oss takes you on, you get real hours and real attention, not a logo on our slide.
Why Oss exists
A raise is a company-sized job. You already have one of those.
Between Series A and IPO, a CEO raises every 18 to 24 months. Each round is four to six months of full-time work (narrative, materials, targeting, meetings, diligence, negotiation) stacked on top of running the company.
And at that table, everyone holds a position. Banks are paid to close, at any price. Advisors are paid for hours. Insiders want their entry. The only person whose job is the founder's outcome is the founder.
Oss exists to change that math. We sit on your side of the table, and we win when you win. Only then.
Approach
Unconflicted, by design.
No fund. No fee from investors. No hours to bill. One loyalty.
Inside, not alongside.
We learn the company before we advise it: the model, the metrics, the roadmap, the room. By the time investors ask the hard question, we've already rehearsed the answer.
Years, not transactions.
Most clients run more than one round with us. We're building your investor machine, not billing your event.
Truth, early.
You'll hear what the market will say before the market says it. Bad news first. That's what the seat is for.
What we do · one thing
We run the round together.
From the first line of the narrative to money in the bank, Oss owns the back end of the raise. You take the meetings that matter. We handle everything around them.
Raised faster. On better terms. From better investors.
A round with Oss, typically four to six months
01
Narrative & strategy
Position the round before anyone sees a deck: the story, the metrics that carry it, the price logic.
02
Materials & data room
Deck, model, memo, Q&A. Built to survive diligence, not just the first meeting.
03
Investor targeting
The right 30–40 funds for this round, mapped and prioritized, warm paths found. No spray lists.
04
Process & momentum
Sequenced outreach, parallel conversations, weekly pipeline reviews. Momentum is manufactured, not hoped for.
05
Negotiation & close
Term sheets compared, syndicate composed, docs pushed to wire. We stay until the money lands.
Between rounds
The raise ends. The relationship doesn't.
What investors learn about you between rounds decides the next one. Oss keeps that channel working.
01
Board decks
Clear, true, and board-ready.
02
Quarterly updates
Investors stay close, and warm.
03
Stakeholder comms
One voice to the whole cap table.

Who you work with
Oss is Marcial Gonzalez Fraga.
Operator first: Mercado Crédito, MercadoLibre's lending business. Then investor: Latitud, backing founders across Latin America. Along the way, 3,000+ interviews with founders and executives: a long study of why some rounds close and others stall.
When you hire Oss, this is who shows up. No juniors. No handoffs. The person who writes the narrative is the person in the room.
Shall we climb together?
Oss takes on a handful of new clients a year, usually CEOs planning a raise in the next 3 to 9 months. If that's you, write to Marcial directly: two lines on the company, and the round you have in mind.
marcial@foundeross.comOss: to show up under pressure, and not leave. That's the job.
