The history of Prosapient
ProSapient has client-service offices in London, Raleigh and Lisbon, and a technical development team in Kyiv. It previously operated Barcelona and Toronto offices. One co-founder previously worked at Coleman Research. The company initially grew with a low-cost offering, selling both expert calls and surveys. Over the years, it did five equity funding rounds:
£4.65m in 2022 in a series of transactions. The company also raised debt from bank Leumi ABL.
£1.5m in Nov 2023 in an internal bridge round, matched by a £1.5m loan (and settling the previous loan) at a whopping 16% interest rate. The lender was a newly formed company owned by one of the company's investors. The first loan principal repayment is due in 2025.
ProSapient competitors in the European consulting segment include Dialectica, Guidepoint and Atheneum. In December 2021, there was a big change in the leadership team. A new CEO took up the reins in December 2021, but left after two years. Currently, Prosapient is led by an ex-McKinsey consultant.
Mid-2023, a former Prosapient manager co-founded the expert network ENCO Insights.
Tech investments
The ProSapient expert network is one of the handful firms outright stating they use AI and machine learning in their work. Much of this technology is common across all larger expert networks. That said, various networks emphasize it more than others in their marketing. These include NewtonX, CleverX, Techspert.io and Atheneum (after its acquisition of Chime Advisors).
Service offering
The company offers a few different services. It states that "If Bloomberg is a platform that allows you to find and consume data, proSapient is the platform that allows you to create it".
The main services are:
Expert interactions (1-on-1 phone calls, meetings and placements), and an app to chat over
Surveys
A transcript library (deprioritized since 2021 under new CEO)
An expert network aggregator (deprioritized since 2021 under new CEO)
The two latter ones are reminiscent of the Inex One platform. The main difference is that Prosapient seeks to be both an expert network and an "aggregator". This raises various strategic challenges, e.g.:
Will other expert networks agree to have their data on their competitor's platform?
Will Prosapient resist the temptation to access such data, or give preference to its own expert network services?
Where will the company management focus their attention? Which clients or service lines will be prioritized?

Coleman Research faced a similar strategic challenge in 2019, and ultimately pivoted their offering away from aggregating content from its competitors. Whichever the outcome at Prosapient, we like their ambition to improve the industry with tech.
Expert Management Systems create transparency and efficiency in the industry. Therefore, they are a logical next step in the history of expert networks. In addition, they’re valuable to the users – here’s how a bank saved >40% on expert network costs by using Inex One.
