Board Advisor or NED: which does your startup need?

What is the difference between a Board Advisor and a NED?

A Board Advisor gives you specialist advice under an advisor agreement. They don’t sit on the board, don’t vote and aren’t a director. A non-executive director (NED) is a formal director appointment: they sit on the board, vote on its decisions and carry the same legal duties as every other director.

Our guide to board roles also explains how a Chair and a Fractional Leader fit in.

When is a Board Advisor the right call?

A Board Advisor is the right call when you have one clear gap and you don’t yet need to change who governs the company. That is where many startups are before, or just after, a seed round. Typical reasons:

• One specialist problem. Your first sale into banks, pricing, a senior hire you’ve never made, or a move into the US.
• No priced round yet. Your board may be just the founders, and adding a director brings formality you may not need yet.
• A sounding board for the founders. Someone who has done it before, on hand for the hard conversations.
• A trial run. Working together as advisor first lets both sides find out whether a board seat would work later.

An advisor’s strength is also their limit. They can tell you what they think, but they can’t hold the company to account or vote on its decisions.

When do you need a NED instead?

You need a NED when the board itself needs an independent voice, not just the founders. The usual moments are:

• Investors join the board. After a priced round, often a Series A, a board of founders and investor directors gains from someone independent of both.
• Your investors expect one. Many venture shareholders’ agreements give investors a say over who joins the board, so read yours and ask your lead investor what they expect.
• You move into a regulated market. Regulators want to see how the company is governed. A firm applying to become an authorised payment institution, for example, must describe its governance arrangements and internal control mechanisms in its application (Payment Services Regulations 2017, Schedule 2, paragraph 5).
• A raise is coming. New investors will look at who sits on your board and how it works.
• Your advisor is doing a director’s job. If the board simply follows what your advisor decides, it’s time to appoint them properly. The next section explains why.

If you’ve decided you need a NED, our guide on how to find a NED for your startup takes you through the search step by step.

The shadow director trap: when an advisor becomes a director

Calling someone an advisor doesn’t settle it. The Companies Act 2006 says a director includes “any person occupying the position of director, by whatever name called” (section 250).

There is a second test. A shadow director is a person “in accordance with whose directions or instructions the directors of the company are accustomed to act” (section 251). Advice given in a professional capacity doesn’t count on its own, but an advisor whose word the board routinely follows can cross the line. If they do, the general duties apply to them too, as far as they can (section 170(5)).

That matters for both of you. The advisor takes on duties they never agreed to, and the company’s decisions start coming from someone the public register doesn’t show. Keep the line clear:

• The advisor advises. The board decides, and the minutes show it.
• Don’t let an advisor sign for the company, instruct your team or negotiate on the company’s behalf.
• Don’t call them a director on your website, in your deck or on LinkedIn.
• If they are running decisions in practice, appoint them as a NED and do it properly.

How do you find a Board Advisor?

1. Name the one gap. Write down the problem you want help with in the next six to twelve months. If you can’t name it, you may not need an advisor yet.
2. Write a short brief. Cover the problem, the experience that would help, the time you expect and what you can offer.
3. Ask for introductions. Your investors, other founders, your lawyers and your accountants all know experienced operators.
4. Widen the search with a board hiring platform, so you aren’t limited to the people your network already knows.
5. Meet a few people and take references. Ask what they did for the last company they advised, then call that founder.
6. Put it in writing. An advisor agreement should cover the scope, the time, how they’re paid, the term, confidentiality, who owns the work and how either side can end it.
7. Review it after an agreed period. Keep it, change it or end it, and decide whether a board seat makes sense.

Quick answers

Should a seed-stage startup get a Board Advisor or a NED?

Usually a Board Advisor, for one specific gap. Move to a NED when investors join the board, when you enter a regulated market or before a raise where your board will be judged.

Can a startup have both?

Yes. Many boards add a NED for governance and keep advisors for specialist areas. Make sure everyone knows who decides and who advises.

Does a Board Advisor need to be registered at Companies House?

No, because they aren’t a director. If they start acting as one, the law may treat them as one anyway.

Can a Board Advisor become a NED later?

Yes. Appoint them formally under your articles and shareholders’ agreement, make sure their identity is verified with Companies House, and file the appointment.

Is an advisory board the same as a board?

No. An advisory board is a group of advisors with no legal power over the company. Decisions stay with the directors.

How Boardly helps you find a Board Advisor or a NED

Boardly is the board hiring agent for startups: the platform where VC-backed founders hire Chairs, NEDs, Board Advisors and Fractional Leaders. It works the same way for either role:

1. You have a ten minute chat with Veronica, our AI agent, about where your company is heading and where the gaps are.
2. She writes the brief with you as you go.
3. A shortlist from our closed community of verified, hand-vetted members comes back in minutes. Only the people who match ever see the role, so your search stays confidential.
4. You pick who you’d like to meet, and we make the introductions over email.

Reviewing your shortlist is free. You only pay if you appoint someone, and it’s one flat fee set by the role and how much you’ve raised, never a percentage. A Board Advisor costs half as much as a NED: £3,000 if you’ve raised under £5m (including if you haven’t raised yet), £6,000 from £5m to £30m and £9,000 over £30m, against £6,000, £12,000 and £18,000 for a NED. Fees exclude VAT, and you can see every fee on our pricing page. Candidates never pay to join.
