How to Run a 90-Day Advisor Trial

A 90-day advisor trial is how founders learn whether an advisory relationship creates real progress before locking in a longer mandate. You set named outcomes, agree a cadence of roughly 2–4 days a month, and check whether the work is landing at day 30, 60, and 90. Done well, the trial tells you whether to extend, stop, or rematch. Done poorly, you burn calendar and goodwill on vague "be available" promises.

This is a decision and process guide for company-side founders and CEOs, not a drafting tutorial. For role boundaries, see startup advisor vs consultant and fractional executive vs startup advisor. For the role itself, start with what is an advisor.

Name the outcomes before day one

Start with one growth problem the advisor should move in the next 90 days: first meetings in a market you do not know, a cleaner fundraising narrative and live investor list, pipeline you could not open alone, or sector credibility with named doors. Write the outcomes in plain language so both sides can score them later. Avoid soft goals like "strategic input" or "be a sounding board." Those never fail a review because they never defined success.

Keep the list short. Two or three measurable outcomes beat a long wishlist. Examples that work: "eight qualified buyer conversations in Germany," "warm intros to three Series A funds that fit our stage," or "a partner shortlist of five distributors with at least two first meetings booked." If you cannot describe what "done" looks like in one sentence per outcome, the trial is not ready to start.

Boardio typically writes the advisor brief and runs the search against your market, sector, stage, and outcome. Your job on the company side is to own the problem definition and the decision criteria, not to invent a search process from scratch.

Set the cadence: 2–4 days a month

Most advisor roles run at 2–4 days per month, often remote: one working session, async follow-up, and introductions when the timing is real. That is enough for judgment and doors. It is not enough to run a function for you. Write the rhythm down before the first session: meeting date, who joins, what prep you send, and how intros are requested.

Quarterly-only check-ins are usually too thin for a trial. Monthly working sessions with async access between them give you enough signal by day 60. If the advisor needs more than a few days a month to deliver the outcomes you named, you may have an operator gap rather than an advisor gap. Re-read the fractional versus advisor distinction before you stretch the mandate.

Protect the calendar. Cancelled sessions without a written async alternative are an early warning. So is an advisor who never asks for context, never follows up on intros, or only shows up when you chase them. Cadence is not bureaucracy. It is how you make progress visible inside 90 days.

What "done" looks like in a 90-day advisor trial

Use fixed checkpoints so the 90-day advisor trial does not drift into an indefinite coffee relationship.

Day 30: Working rhythm is set. You have held at least one full working session, shared the live materials that matter (pitch, ICP, pipeline, or market plan), and agreed the first intros or reviews. Early proof looks like a concrete next action list, not a second pep talk. If you still cannot name what the advisor will do in month two, stop and reset the brief with them.

Day 60: Mid-trial proof. You should see tangible movement against the named outcomes: meetings booked, intros made, narrative tightened, or a clear kill list of paths that will not pay back. Quality matters more than volume. Three warm, relevant conversations beat twenty cold names. Document what landed and what stalled so the day-90 decision is evidence-based.

Day 90: Extend, stop, or rematch. Score each named outcome: hit, partial, or miss. Decide whether the relationship compounds for another 90–180 days, whether the problem is solved enough to pause, or whether the profile was wrong and you need a different match. A clean stop is a successful trial if it saved you from a weak long-term arrangement.

Map equity, cash retainer, and revenue share to the trial

Compensation for the trial should match the work, not a generic template. Always discuss the full set: equity, cash retainer, and revenue share. Equity fits long-horizon judgment and multi-year alignment (typical early-stage advisor grants often land around 0.1–0.5% with vesting). A cash retainer fits predictable access and monthly effort (lighter European retainers often sit around €500–€2,000 per month). Revenue share fits attributable commercial intros and deals with clear caps.

For a 90-day window, many companies use a modest cash retainer so calendar priority is real, then layer equity or revenue share if you extend. Some start equity-light with vesting that begins only if you continue past day 90. Others pair a small retainer with capped revenue share when door-opening is the main job. Document triggers, vesting, and what counts as a qualifying introduction before the first working session. For a deeper pay-model filter, see equity vs cash retainer vs revenue share.

When to extend, stop, or rematch

Extend when named outcomes moved, cadence held, and both sides want another cycle. Stop when the outcomes were wrong for an advisor, the company side did not use the time, or the relationship is polite but inert. Rematch when the problem is still real but the profile, market, or network access was off.
