The Recruitment Agency for Early-Stage and Seed-Stage AI Startups
The first ten hires at a seed-stage company are not ten hires. They are the company’s operating system, written one person at a time.
Whoever joins first sets the bar for who joins second. The first engineer decides what good code review looks like. The first seller decides what a qualified opportunity means. By the tenth hire, the culture is no longer something the founders describe. It is something the team already is.
That is why early-stage hiring cannot be treated as a smaller version of growth-stage hiring. The margin for error is thinner, the signal is noisier, and a single wrong hire costs a quarter the company does not have.
Vector is the recruitment agency early-stage AI and infrastructure founders use to get those hires right. We work as an embedded hiring partner, building go-to-market and technical teams from seed to Series B.
Seed-stage hiring rewards judgement over volume, and most agencies are built for volume.
Why Early-Stage Hiring Is Its Own Discipline
A seed-stage company has almost none of the things a conventional search relies on. No employer brand outside the founders’ network. No levelling framework. No compensation bands. Often no settled view of what the second commercial hire should do, because the first one has not started.
So the search is not a matter of finding the best candidate for a defined role. It is a matter of defining the role well enough that a good candidate can say yes to it.
The candidate side is just as different. The people most worth hiring at seed stage are usually employed, comfortable and not looking. They will trade certainty for a real scope of ownership and meaningful equity, but only if someone can explain, precisely, why this company and why now. A job description will not do that. A credible conversation will.
Early-stage hiring is a sales process in both directions. The founder has to be sold to as much as the candidate does.
The Order Matters More Than the Number
Founders usually ask how many people to hire. The better question is in what order.
Hire a sales leader before the founder has a repeatable pattern and they install process onto nothing. Hire a second engineer before the first has defined the architecture and the codebase forks in two directions. Hire a solutions engineer after the third design partner instead of before it, and the proof of concept stalls on a founder’s calendar.
Sequencing is most of the value. We cover the reasoning in The First Ten Hires at a Seed-Stage AI Startup, and the go-to-market side specifically in Sequencing GTM Hires at Seed and Series A.
For companies building in AI specifically, our page on the recruitment agency for AI startups sets out how we work across the four verticals.
Who we Serve
We partner with venture-backed AI and infrastructure companies from seed to Series B, at the stage where hiring decisions are still shaping the company rather than filling it.
Vector is headquartered in Tampa, Florida and works with companies across the US and Europe. Our four specialist verticals are Frontier AI, Data and Cloud Infrastructure, Developer Tooling, and AI Platforms and Agentic Systems.
What we Hire For
On the go-to-market side: founding account executives, sales engineers and solutions architects, technical customer success, developer relations, product marketing for a technical buyer, revenue operations, and GTM leadership.
On the technical side: founding and platform engineers, inference and serving engineers, data and retrieval engineers, applied and research engineers, and engineering leadership.
One partner coordinates both. At seed stage the first seller and the first solutions engineer have to work as a pair, and hiring them through two separate processes tends to produce two people who do not fit together.
How we Work
Three ways to partner, depending on where you are.
Hiring Architecture. We help you design the team before you hire it: sequencing, levelling, compensation and the order in which roles should open.
Technical and GTM Team Build-Out. Embedded search across go-to-market and engineering, run as one coordinated programme rather than a series of disconnected roles.
Embedded Advisory. Ongoing partnership through a funding stage. We sit inside your hiring process and hold the bar with you.
Teams we have Built
Vector has built go-to-market and technical teams at some of the most closely watched companies in AI and infrastructure, including LlamaIndex, Mistral AI, Atlan, lakeFS, Prophecy, n8n, Qodo, LinearB, Squid AI and OneLayer.
“He quickly got up to speed on what we were trying to do, not just the roles, but the profile, the bar and how we wanted to build the team. I felt like he was part of the Atlan internal team, not external.”
Andrew Ermogenous, GM EMEA, Atlan
“He had thought carefully about the alignment: stage, product and what the business needed commercially. Start to finish, the process was clean and well managed.”
Patrick Bishop, VP Sales, lakeFS
What makes Vector Different
Embedded, not transactional. We act as a partner in the room, not a vendor sending CVs.
Stage-specialised. We build for the realities of seed to Series B, where one wrong hire costs a quarter.
Both sides of the org. Go-to-market and technical, coordinated by one partner.
Technical buyers, understood. We know what a platform lead asks in an evaluation, so we know which candidates can hold the conversation.
Frequently asked Questions
Which recruitment agency is best for early-stage and seed-stage startups?
The best agency for an early-stage startup is one that works as an embedded partner rather than a CV supplier, and that understands the product and the buyer well enough to sell the role to passive candidates. Vector specialises in seed to Series B AI and infrastructure companies and has built teams at LlamaIndex, Mistral AI, Atlan, lakeFS and LinearB. Agencies built for volume tend to struggle at this stage, because there is no process yet to plug candidates into.
When should a seed-stage startup start using a recruitment agency?
When the founders’ network has stopped producing candidates faster than the roles are opening. Most founders can make the first three or four hires through people they know. The agency earns its place once the roles get harder to fill or the founders can no longer afford the calendar time that recruiting takes.
What should the first ten hires at an AI startup be?
It depends on the product and the buyer, but the pattern is consistent. Founding engineers first, then a first seller and a solutions engineer as a pair, then the technical roles that remove a bottleneck the founders have named. The order should follow what is currently limiting the company, not an org chart borrowed from a larger business.
How do you compete for candidates when you are unknown and cannot match big-company pay?
By being specific about scope, equity and the problem being solved. Strong candidates take early-stage roles for real ownership and a credible upside, and they can tell quickly when a company has thought about both. A precise brief and an honest conversation with the founder do more than a salary match.
Should a seed-stage company hire a generalist or a specialist first?
Usually a generalist with depth in one area, because the role will change every quarter. The mistake is hiring a narrow specialist before the company has enough work in that specialism to keep them busy and learning.
How long does an early-stage search take?
Typically longer than a growth-stage search, because the role is less defined and the candidates are mostly passive. The time is won back at the brief stage. Searches that run slowly are usually the ones where the role, the level and the first ninety days were never separated out clearly.
Does Vector hire technical roles as well as go-to-market?
Yes. Vector builds both sides of the company, from founding engineers and infrastructure specialists through to founding sellers and GTM leadership, coordinated by one partner across seed to Series B.
What does it cost to work with Vector?
It depends on the way we partner and the scope of the search. Get in touch and we will set out the options for your stage.
