Gerson Lehrman Group is an international consulting firm that matches freelancers with corporate clients who need expert advice. GLG is one of several firms that aim to match their clients with freelance experts. 

Like competitor Maven, GLG requires prospective consultants to click through an extensive questionnaire that highlights the many conflicts of interest that consultants might encounter. Specifically, if you are currently working, you are not allowed to provide any non-public information about your employer — or about any other public company. You also must abide by your own company’s rules about working for competitors. 

You are able to accept or decline any project for any reason. And you are allowed to cut calls short — at full pay — if the client is asking you to breach your ethical duty to your employer or violate any laws or regulations.

Rates and fees

Gershon Lehrman Group helps you set your own consulting rate with an online calculator. However, GLG’s calculator is likely to simply divide your estimated annual salary by 2,000 hours. (That’s the average annual hours assuming a 40-hour week and two-weeks vacation.) Gershon Lehrman Group’s competitors generally suggest higher rates. Maven, for example, assumes that you should set your rates at two-to four-times your normal hourly pay.

However, the chance of getting a consulting gig with GLG appears to be far better than it is with Maven. That may be because both sites add their own fees onto your rates, which boosts the final cost to clients. You will get whatever rate you’ve set when you’re hired, but you’re less likely to be hired if you have high rates. The exception to that rule, of course, is when your skills are rare and in high demand. 

Unlike some other sites that keep your identity obscured until you’re hired, GLG imports your LinkedIn information. That’s convenient, cutting the amount you need to write. But it’s a disadvantage if you want to keep your consulting side hustle close to the vest. 


Even though Gershon Lehrman Group appears to offer more consulting gigs than some of its competitors, consulting is not regular work. You may get a job or two per month. And many of those are likely to involve an hour or less of your time.

That said, none of the consulting platforms restrict you from signing up with their competitors. It’s not a bad idea to register with multiple consulting sites. Others to consider: Maven and Zintro.

What their users say (from Indeed)

“From time to time someone needs specialized help that i’m qualified to help with, probably only about 5 hours a quarter. However, i’m compensated extremely well for this time. It’s very low pressure when deciding whether to take a project or not.”

“Lots of varied Aerospace/Aviation consulting opportunities with major OEM’s regarding Airline and Military operations.”

“It is great money for the amount of time a project or consultation requires. All consultation opportunities are accepted or declined based on my choice.”

“They paid me over USD 300 per 10 minutes for the consulting time.”

“Excellent working conditions with the ability to provide help and resolutions for major customers and stakeholders. Great for persons looking for side income. All work is prescreened to make sure customers agree with the talent needed.”

(from Quora):

“I’ve been on GLG for some 8 years and have done some really interesting and well-paying consultations that were referred to me through their network. But they’re few and far between. Most of the consultations are for half an hour. So for me, it’s pocket money.”

“I have done over 50 consultations with them over a 2 year period. The flexibility of being able to quote your own rate, and be able to do it at your convenience helps too. A majority of the clients I work with, are on the East coast of US, and so I’m able to take early morning calls while driving to work on the West coast. Win win for everyone!”

“Most engagements are 1/2 hour. And when it’s all said and done, I’ve probably spent 4 hours of my time responding and communicating with GLG for every hour I have been paid. Might be time to pull the plug. Three years have passed with very marginal return on my time.”
