The Proving Phase

By · · 10 min

I run a venture studio in its proving phase. I have not written an investment check, and I am not writing one today. This is the model the studio is running on, how it scales, and the public commitment to the operating cadence underneath it.

I run a venture studio. I have not written an investment check. I am not writing one today.

Crunchbase classifies me as an investment firm. The classification is automatic, because the data infrastructure built for the startup world only has two slots: founder and investor. A venture studio is neither. The system asked me to declare myself one or the other on the way in, and the only category that approximated what I do was investor, so investor is what the profile says. The result is that my Crunchbase page sits in thirteen investor lists today. Most of the people landing on it expect a check writer. They are not going to get one.

I am writing this so the model is in writing, in my voice, before the data infrastructure or the default narrative paper over what it actually is. Not because the model is fixed for life. Because the model is what we are running on, what founders are signing up for, and what every claim on this site is grounded in. If it changes, the change deserves to be a published event, not a quiet drift.

Relay 1 is in its proving phase. The studio is in its first year. The work right now is documenting that the operating model holds, that the playbook sharpens across every build, and that the trade we are asking founders to make returns more for them than a check on the same deck would have. Whether the studio eventually evaluates a fund vehicle is a downstream question, not today's question. Today's question is whether the studio earns the equity range it is asking for. The proving phase is the answer to that question. Most studios skip the proving phase. We are not skipping it. The proof is the asset.

The default looks like a fund

Most venture studios I know of eventually take fund structure. The arc is consistent. Year one, two or three operators co-found two or three companies, drawing personal capital and outside client revenue to cover salaries. Year three, a studio fund one gets announced, usually pitched as small at twenty-five to seventy-five million, usually justified as we need follow-on capacity for our portcos. Year five, the operators spend most of their time managing LPs and deploying capital, and the actual build work gets handed to an associate or contractor layer below them. The studio is now a fund with a content layer.

I understand the pull. The fund structure solves three real problems. It pays the studio a management fee that does not depend on a portfolio company's revenue. It gives the studio a follow-on instrument so portcos do not have to find new lead investors at every stage. It provides scale capital, so the studio can drive growth across the portfolio without selling more outside work. The pull is not irrational. Every problem the fund solves is a real problem.

I am not solving those problems that way today. Once you take LP capital, your job changes. Your time gets carved into LP relations, fund reporting, capital deployment, follow-on negotiation, and the politics of allocation. The thing you came here to do, which is co-found companies, becomes a smaller and smaller percentage of your week. Three years in, you are running a fund. Five years in, the studio brand is the marketing wrapper on a small fund that happens to participate at formation. The build work, the thing the founders co-founded with you for, is no longer the work you spend the most time doing.

Most studios take that trade because the alternative looks like a ceiling. I think the alternative is a ceiling, but it is the wrong ceiling to break in year one. The thing the studio is selling, the thing that earns the equity, is the studio in the work. That is the asset. Adding LP capital before the asset is proven does not multiply it. It dilutes the asset's time, which means it dilutes the asset itself. The right move, at this phase, is to push the ceiling out by sharpening the operating system and earning the playbook on real companies, not by replacing the asset with a fund instrument that competes with it for the studio's hours. The fund question gets a real answer after the playbook is proven. Not before.

What I am doing instead

The model that lets me not write checks is in three pieces.

First, the studio takes twenty-five to thirty-five percent equity at formation, in exchange for the full build. Product, brand, go-to-market, automation infrastructure. Same vesting cliff as the founder. The equity is not a check. It is the price of the build, paid in ownership, settled at the moment of formation.

Second, the studio takes co-founder compensation. Like any co-founder, the studio is on the same compensation discipline as the founder: deferred until the company can support it, scaled to what the company's stage actually pays. Pre-revenue, that is often zero or a token amount, deferred until first revenue or a round closes. Post-revenue or post-seed, compensation lands at the rate a traditional co-founder draws at that stage, in the five to ten thousand dollar a month range at first revenue and ten to twenty thousand a month post-seed, tapering to advisory compensation as the company builds out its own operating team at scale. The studio takes co-founder compensation. The studio is a co-founder.

The equity is the co-founder grant for the build at formation. The compensation is the co-founder draw for the ongoing work. Both are co-founder economics. They are split across the timeline because the timeline of the contribution is split.

Third, the studio takes outside client engagements when the work fits our verticals or sharpens our internal playbooks. Same operators, same standards, same weekly cadence. The outside-client revenue funds the studio's operating costs while portfolio companies grow into the co-founder compensation they will eventually support.

That is the whole model. There is no fund vehicle. There is no LP. There is no management fee on committed capital. The studio is funded by co-founder equity that compounds with the portfolio, co-founder compensation that comes online as portcos can support it, and outside-client revenue that carries the studio through the proving phase. The mix shifts over time as the portfolio matures. The proving phase leans on services revenue. The mature phase leans on equity and ongoing compensation.

The studio is the co-founder. Named on the charter, signed onto the operating agreement, vested on the same cliff as the founder. Relay 1 shows up on every charter, every weekly review, every build call, with the actual operators in the room. We do not delegate co-founding work to an associate layer. The studio is what the founder is buying, and the studio is what the founder gets.

How we scale

The first question I get after "are you raising" is some version of "how do you scale without a fund?" The implication is usually that you cannot scale a studio without LP capital, because operating bandwidth is finite and capital is the only thing that breaks the bandwidth constraint.

That is the lazy version of the question. The real version is: how do you increase output, return, and reach without compromising the operating cadence that is the whole reason a founder picked you in the first place?

For Relay 1, the answer is in three pieces.

Compression. The build window for an AI-native company is six weeks, not twelve months. The studio, applied at compression, co-founds more companies per year than a studio working at 2018 tooling could co-found in three. The constraint that used to cap studio output is gone. The studio is now limited by founder pipeline and operating attention, not by build capacity.

The operating system. Every company we co-found sharpens the playbook for the next one. Hiring rubric, GTM motion, brand system, automation stack, dashboards, customer-experience patterns. Each portco contributes a layer to the studio's operating system, and each new build starts with more of the system already built. The marginal cost of company N+1 is meaningfully lower than the marginal cost of company N. That compounds across the portfolio.

The services arm. Relay 1 Automations is the outside-client business, structured as a separate brand and surface, building AI workflow automation for B2B sales companies and home services operators. Same operators, same standards, same weekly cadence. The services arm funds the studio's operating costs while the portfolio compounds. It also sharpens the studio's playbook, because every automation build is a controlled experiment inside an operating company that is not ours, on workflows our portfolio will eventually run into too.

These three together get the studio to a portfolio of six to ten active companies at any moment, a hundred-plus companies co-founded across a decade if the pipeline holds, and outside-client revenue that funds the build without raising. That is the model running today.

There is a separate question, which is whether the studio eventually rolls into a fund structure. The honest answer is that it might. Studios that prove their operating system and earn a documented playbook eventually have a real choice to make about whether a fund vehicle compounds the proven work or dilutes it. That choice gets made on the other side of the proving phase, with real data and real portfolio context behind it, not on a deck at year one. The structure follows the work. The work does not follow the structure.

Why founders trade for the studio instead of the check

Capital is not the bottleneck for an AI-native company in 2026. The check has been commoditized. There are thousands of pre-seed funds, hundreds of accelerators, and dozens of platforms that will write a hundred-thousand-dollar check on a deck for a strong founder. What is not commoditized is a co-founding studio that ships the build, designs the brand, runs the GTM, and stays in the work through scale. That is what Relay 1 sells. Not the money. The studio.

The math works out if you think the studio, applied to a strong founder with a real wedge, outperforms a hundred-thousand-dollar check on the same founder. I think it does. By a meaningful multiple. I think the founders we co-found with would agree, or they would not sign over a quarter of the company for it.

If I am wrong about that, the model fails. Not because the math is broken, but because the value proposition is. If founders three years from now would rather have the cash than the operators, the studio model in this configuration stops working. I am willing to take that bet. I think the next ten years go the other direction. The cost of capital keeps falling. The cost of finding a real operating partner does not.

The tradeoffs I am taking today

I want to be honest about what the current model is costing me, because the absence of the disadvantages should not be left implicit.

No follow-on vehicle. When a portco hits Series A and the round is competitive, I cannot write a check to protect pro-rata or to signal continued conviction with capital. I rely on the studio's operating stake carrying its weight in the negotiation, and on the founder running their own capital strategy well enough to bring the right investors to the table without my balance sheet behind it.

No fund-level optionality. If the studio needs to take a bigger swing on a single company than ongoing co-founder compensation can fund, I cannot reallocate fund capital to do it. The bigger swing has to come from the founder's round or from the studio's own balance sheet, which is outside-client revenue and retained co-founder compensation.

No GP carry. Carry on a fifty-million-dollar fund returning three times capital is twenty million dollars split across the GP team. The studio model bets that operating equity from co-founding even ten companies, with the studio taking thirty percent at formation, outearns that share over the same decade. The bet pays out only if the companies actually win. If the hit rate disappoints, operator-equity returns less than fund-carry would have. Fund-carry is a steadier floor. Operator-equity is a wider distribution. I picked the distribution that pays off when the work is good.

A capped number of active portcos. The studio's operating bench is finite. Relay 1 is on every charter, every weekly review, every build call. That caps active portfolio size at six to ten companies, which means the studio's annual economics depend on hit rate more than they depend on count. A fund can deploy across thirty companies in a year. We will not, in this configuration, carry thirty active portcos. We will carry the right ten.

These are real costs of the current model. I am not building under the illusion that the operator-equity-only model is free. I am building it this way because the trade is the right one for the phase we are in. If the phase changes and the trade flips, the model evolves, and the evolution gets written down on this site before it happens. Not after.

What I am asking founders to do

I am asking founders for three things in exchange for the studio as a full co-founder, contributing the build at formation and the operating cadence through scale.

Bring conviction and a sector you have lived in. The studio cannot manufacture domain depth on someone else's behalf. If you do not have a thesis you have earned, the studio is the wrong partner for you. We have co-founded with founder-with-idea and founder-with-thesis both. We have not co-founded with founder-with-vibes.

Own your own capital strategy. We help with the deck and the room. We do not raise on your behalf. The founder is the person investors meet at the seed round, and the founder is the person who closes the round. The studio is a co-founder, not a placement agent.

Be okay with the cap table. The studio takes twenty-five to thirty-five percent at formation, depending on stage of contribution. A typical formation cap table reads fifty-five to sixty percent founders, thirty percent studio, ten to fifteen percent ESOP. After a standard seed round, the founder sits in the low forties and the studio around twenty-two percent, both inside the range sophisticated investors expect at that stage. The studio stake reads as a positive signal at Series A, because it tells an investor there is an aligned operating partner co-locked through scale, not a passive holder or a service vendor with a clipboard.

This is the trade. The studio gives up the fund instrument and the leverage that comes with it. The founder gives up the equity range and the optionality of working with a generalist partner. The bet on both sides is that what we get in return compounds harder than what we gave up.

The commitment

The thing I will not trade away is the operating cadence.

The studio on every charter. Weekly reviews on every portco. Cell phones, Slack, the call when the call has to happen. Relay 1 in the work, not above it. That is the load-bearing claim of this studio. Every other piece of the model, including the no-checks-today posture, is downstream of it. The operating cadence is what founders are buying when they sign over the equity range. If the cadence ever changes, what we are selling has changed, and the founders we have already co-founded with deserve to know first.

I am not pre-committing to never raise capital. I am pre-committing to never raise capital in a way that breaks the operating cadence. Those are different commitments, and the second is the one I actually believe and can keep. The first is the kind of commitment you make to sound principled. The second is the kind you make to stay honest about what you are selling.

What that means in practice. If a fund instrument ever serves the build work, if it gives the studio more time in the build instead of less, if it strengthens the cadence instead of carving it into LP relations and capital deployment and follow-on negotiation, we will consider it. The structure follows the work. We have not seen a fund structure yet that does that for studios at our stage, but I am not going to pretend I have seen every structure that will exist over the next decade.

What I am committing to, in writing, is this. If Relay 1 ever raises an investment vehicle of any kind, a fund, an evergreen, a deployment SPV, a hybrid, the case for it gets published on this site before anything is announced. With the reasoning written out. With the operating cadence implications named. With the alignment to the founders we have already co-founded with addressed in writing. The graveyard is the version of this for ventures that wind down. This essay's commitment is the version for studio-level structural change. No quiet evolution. No retroactive justification. The page changes, or the page comes down, or it stays up and is held to.

That is the same shape of commitment the graveyard is. Not "we will never fail." We will fail. The commitment is to publish what happened. Not "we will never change the model." We might. The commitment is to publish the case before the change. Pre-commitment in public is the cheapest form of discipline I know.

What this means for you

If you found your way here from my Crunchbase profile and saw INVESTMENT FIRM at the top, you now know how to read it. The classification is the system's, not mine. The studio is the studio. The model is in this essay. If the model ever changes, the case study lands on this same page before the announcement does.

If you are a founder and you want a co-founding studio more than you want a wire, apply. The terms are public. The cap table math is in the FAQ. The studio is on the team page. The build is the build.

If you want a check today, Relay 1 is not your studio. There are plenty of funds. I am not running one today. I am running the studio through its proving phase, co-founding more companies, sharpening the operating system every quarter, holding the cadence that makes the studio worth picking in the first place. Whether the studio ever evaluates a fund vehicle is a question for the other side of the proof. Today, the studio is the asset, the operating cadence is the bar, and the page you are reading is the commitment.
