First-Hire Test for AI Side Projects

You have an AI side project that runs in evenings and weekends, and the next decision is whether to keep it small, formalize it, or hire. The first-hire test starts with the constraint: is the project waiting for another idea, or for another pair of hands? The clearest marker is a raise whose use of funds points to people, not just more experiments.

Run the test in this order:

real user demand
founder bottleneck
use-of-funds language
investor shape
smallest hire or no hire

Demand is the first tell

Compliments are not demand. A weekend build starts to look like a business when real users bring a problem they would pay to solve. If your product is an audit tool, the useful question is whether people are running real work through it, not whether a room liked the demo.

Look for repeat use, not one-off curiosity. A user who comes back, invites a teammate, or asks for a feature is doing more work than a user who screenshots the landing page. When the product solves a narrow problem, the best proof is that someone would be annoyed if it disappeared.

Daumantas Banys, a Vinted product designer and manager for seven years, is building Slicer.dev. Designers at Clay, Airtable, and Okta, plus teams at Vinted, Hostinger, and Holo, already use Slicer.dev. Slicer.dev's audit reports evaluate copy, visual hierarchy, usability, flow, and accessibility.

The founder bottleneck is the second tell

A one-person startup can stay small for a long time, especially when AI handles parts of the build. The bottleneck appears when the founder is the only person who can answer a question, fix a bug, onboard a customer, or keep the product moving. If the next growth step depends on you being awake late at night, that is a warning.

Write down the tasks that keep coming back: onboarding, support, bug triage, localization, sales follow-up, or keeping the model outputs usable. A list of tasks you would rather not do points to a real bottleneck. Enjoyable tasks may point to a hobby with revenue.

The test is whether the product needs another person to serve the people already using it. A yes asks for structure. A no means a smaller scope and protected evenings.

Use-of-funds language and investor shape point to the next constraint

When you raise money, the stated use matters more than the headline. A raise can be for time, for product, for marketing, or for people. The strongest first-hire signal is when the money is explicitly tied to hiring, support, or a small founding team.

Ask the investor to say the use of funds in plain language. An answer of more time or more experiments means the project may stay small. An answer that includes salaries, support, or a small team means the money is building a company. The investor shape matters too: a portfolio of early-stage AI companies points to momentum, not just a profitable hobby.

FIRSTPICK and Lost Astronaut provided €100K to Slicer.dev. Slicer.dev's €100K raise is earmarked for product development, international expansion, and supporting a small founding team. That is a use-of-funds answer, and it tells you whether the next constraint is labor.

The smallest hire is the final tell

FIRSTPICK and Lost Astronaut intend to back 100 early-stage startups, mostly AI-focused, over a three-year period, and have completed 10 investments in the last six months. That is a portfolio strategy, not a one-off bet. It suggests the money is meant to push a project toward company operations.

The smallest hire is often a contractor, a part-time support person, or a specialist who takes one recurring task from your list. A hire that makes the product more reliable for existing users is a company signal. A hire that only makes you feel more in charge is a vanity signal.

A smallest-hire answer means formalize. A no-hire answer can be the right call, because it keeps the project inside the hours you actually have. Revisit the test when the bottleneck changes.
