Advisor

An advisor is a person or firm engaged to give expert guidance on a decision without taking responsibility for running the business day to day. The role covers a wide range, from a financial advisor managing someone's investments to a board advisor helping a founder think through a fundraise or an acquisition.

What separates an advisor from an employee or a director is that they inform decisions rather than make or execute them.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

Advisors fall into a few broad groups. Financial advisors work with individuals on investments, retirement and tax planning; corporate finance advisors work with companies on transactions such as raising money or selling the business; and strategic or board advisors bring sector experience to a management team on an informal, part-time basis.

The distinction that matters most to clients is the standard of care an advisor owes. Some advisors act under a fiduciary duty, meaning they must put the client's interests ahead of their own, while others work to a lower suitability standard, meaning a recommendation only has to be reasonable for the client's situation.

Asking which standard applies, in writing, is the single most useful question a client can ask. How advisors are paid shapes the advice they give.

Common structures include a flat retainer, an hourly rate, a percentage of assets under management, a commission on products sold, and a success fee on a completed transaction. Commission-based models create the sharpest conflicts, which is why fee-only arrangements have become more common in personal finance.

In start-ups and small companies, advisors are often compensated with equity rather than cash. A typical arrangement grants a small percentage of the company, commonly between 0.1% and 1%, vesting over one to two years, in exchange for a defined commitment such as monthly calls and named introductions.

An advisor is not a director and normally carries no legal duty to the company as a whole, no vote and no liability for board decisions. That difference should be documented, because informal advisors who behave like directors can in some jurisdictions be treated as directors in substance, with the responsibilities that follow.

In practice

Real-world examples.

1

Example

A couple approaching retirement engages a fee-only financial advisor at a flat $4,000 a year to consolidate four pension pots and set a withdrawal plan, deliberately avoiding a commission-based arrangement.

2

Example

A software start-up brings on a former marketplace operator as a board advisor, granting 0.5% of equity vesting monthly over two years in return for two calls a month and warm introductions to three named retailers.

3

Example

A family-owned engineering firm hires a corporate finance advisor to run a competitive sale process, paying a monthly retainer plus a success fee, and credits the advisor with attracting two bidders the owners had never considered.

Formula

Calculation

Advisory fees are usually calculated in one of two ways: Asset-based fee = assets under management x annual fee rate Transaction fee = (monthly retainer x number of months) + (deal value x success fee rate) An individual places a $3,000,000 portfolio with a wealth advisor charging 0.85% a year. Annual fee = $3,000,000 x 0.85% = $25,500 Separately, a manufacturing company hires a corporate finance advisor to sell the business. The engagement letter sets a retainer of $10,000 a month for six months, plus a success fee of 1.5% of the final sale price. The business sells for $20,000,000. Retainer paid = $10,000 x 6 = $60,000 Success fee = $20,000,000 x 1.5% = $300,000 Total advisory cost = $60,000 + $300,000 = $360,000 Many engagement letters credit the retainer against the success fee, in which case the total would be $300,000 rather than $360,000, so it is worth checking that clause before signing.

Case study

Seen in the real world.

This case is illustrative and fictional. Marlow Grain Handling, an invented agricultural equipment business, decided to sell after 30 years under one family. The owners initially planned to negotiate directly with the first buyer who approached them, a competitor offering $14,000,000.

A friend of the family, acting informally as an advisor, suggested they test the market properly and introduced them to a corporate finance firm. That firm charged $10,000 a month for six months plus a 1.5% success fee, ran a process with nine potential buyers, and produced three competing offers.

The business eventually sold for $20,000,000, and total advisory fees came to $360,000. The owners noted afterwards that the fee looked large in isolation but small against the $6,000,000 improvement in price, and that the advisor's most valuable contribution had been the discipline of a structured process rather than any single negotiation point.

Watch out

Common mistakes.

  • Assuming every advisor is legally required to act in your best interests. Many operate to a suitability standard instead, so the duty owed should be confirmed in the engagement letter rather than assumed.
  • Focusing only on the headline fee rate. How the advisor is paid, and by whom, often affects the advice more than the size of the fee.
  • Appointing start-up advisors with no written scope or vesting schedule. Equity granted for a vague promise of help tends to sit on the cap table long after the help has stopped.

Questions

People also ask.

What is the difference between an advisor and a consultant?

An advisor generally provides ongoing guidance on decisions, while a consultant is usually engaged for a defined project with specific deliverables and a fixed timeframe.

Is an advisor the same as a board member?

No, a board member has legal duties, voting rights and liability, whereas an advisor attends by invitation, has no vote and normally carries no statutory responsibility for the company.

How much equity should a start-up advisor receive?

Typical grants run from 0.1% to 1% depending on seniority and commitment, almost always with vesting over one to two years and a clean termination clause.
