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 has done several equity funding rounds:

• 2017 - Raised £1.3m

• 2019 - Raised £2m

• 2020 - Raised ~£2.5m

• 2021 - Raised £7.3m

• 2022 - Raised £4.65m in a series of transactions. The company also raised debt from Bank Leumi ABL.

• November 2023 - Raised £1.5m 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 was due in 2025.

• February 2026 - A further Series A round, but no specific amount was disclosed.

Employee headcount tells a consistent story alongside this financing history: workforce fell to a low of 335 in Q4 2023 (around the same time of the risky bridge loan), before recovering - up 22% from 2023 to 2026, reaching 500+ across current trackers. The February 2026 funding round is itself a good signal that the 2023 financial strain was successfully managed.

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.

In mid-2023, a former proSapient manager co-founded the expert network ENCO Insights.

proSapient joined the Tech Nation Future Fifty 2025 cohort, a prestigious programme for the UK's high-growth, late-stage ventures.

Tech investments

The proSapient expert network is one of the handful of firms that outright state 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 it acquired 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:

1. Expert interactions (1-on-1 phone calls, meetings, and placements), and an app to chat over

2. Surveys

3. A transcript library (deprioritized since 2021 under the new CEO)

4. An expert network aggregator (deprioritized since 2021 under the new CEO)

The latter two 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 its attention? Which clients or service lines will be prioritized?

Coleman Research faced a similar strategic challenge in 2019, and ultimately pivoted its offering away from aggregating content from its competitors. Whichever the outcome at proSapient, we like their ambition to improve the industry with tech.
