AlphaSense Expert Insights

AlphaSense Expert Insights is an expert transcript library, operated as part of AlphaSense, a much larger AI platform for market intelligence and research. This page focuses specifically on the expert-network side of AlphaSense's business, which the company acquired.

AlphaSense Expert Insights is not to be confused with AlphaSights, an unrelated expert network with a similarly sounding name - a mix-up serious enough that it's now the subject of active litigation between the two companies (see Litigation below).

The library began life in 2020 as Stream Research Group, founded by expert network Mosaic Research. AlphaSense acquired it a year later and has since expanded it substantially, most notably by acquiring its largest competitor, Tegus, in 2024.

AlphaSense Expert Insights as a transcript library and expert call service

A transcript library is one of six expert network business models. Instead of arranging one-off expert calls, investment professionals and company employees conduct expert calls (at low or no cost), which are transcribed and added to a shared library. Other clients then subscribe to search and read the library, and may contribute new calls of their own.

AlphaSense Expert Insights has grown beyond a pure library model, however. Clients can also request custom, bespoke one-on-one expert calls directly through the platform (via a "Talk to This Expert" feature), and have more recently added an AI-led interview capability, where an AI interviewer conducts live calls with sourced experts. This complements more specialized offerings like Channel Checks (supply and demand signals from distributors, suppliers, and retailers) and Voice of Customer interviews. In practice, this makes it a hybrid of a transcript library and a more conventional expert-call network, rather than a pure content library.

The library's growth has been steady: it held around 3,000 transcripts in March 2021, adding roughly 300 a month. By the time AlphaSense acquired it in October 2021, it had grown to 8,500 transcripts - a much faster pace of roughly 800 new transcripts monthly. By March 2022, it had passed 10,000. By March 2025, AlphaSense reported over 150,000 transcripts across its combined library (following the Tegus acquisition), and by August 2025 the library had passed 200,000 transcripts. By September 2026, it had passed 280,000.

Other expert network content libraries include Third Bridge's Forum, Guidepoint, GLG, and In Practise. Historically, content on these platforms was generated entirely through in-house analysis, though at least Third Bridge has begun blending in user-generated content too.

Early on, some experts contributing to the AlphaSense/Steam library have publicly claimed they weren't compensated for their participation - a criticism that surfaced on Reddit and Twitter (now X) in the platform's earlier years under Mosaic Research/Steam branding. However, it's not clear whether this reflects current practice.

By contrast, expert calls conducted through Inex One are recorded and transcribed for free, with the resulting transcript library staying private to your own firm rather than being pooled into a shared, subscription-based library.

Milestones

• 2011 - AlphaSense founded as a platform for analyzing financial documents and datasets. Its expert network business came a decade later, through acquisition.

• 2020 - The transcript library launched as Stream Research Group, founded by expert network Mosaic Research.

• October 2021 - Acquired by AlphaSense for $50 million. AlphaSense initially said Stream would operate as an independent entity, integrating the text-processing tech and cross-selling the content library to AlphaSense's existing clients.

• December 2021 - Rebranded to "Stream by AlphaSense."

• May 2022 - AlphaSense acquired competitor Sentieo - the first firm to successfully aggregate and redistribute GLG transcript content. See all M&A activity in the expert network industry.

• 2023 - Rebranded again to AlphaSense Expert Insights.

• June 2024 - AlphaSense announced it would acquire Tegus, its main transcript-library rival, valuing Tegus at $930 million.

• July 2024 - AlphaSense acquired market-report aggregators Marketresearch.com and Profound.com. No formal press release accompanied the deal beyond the seller Freedonia Group's own statement that "it was sold"; a subsequent AlphaSense job posting confirmed the acquisition.

• November 2024 - AlphaSense conducted a round of layoffs, drawing some attention to LinkedIn. Not entirely unexpected to right-size after an acquisition spree, but this was a new kind of signal as it prepared for a possible IPO.

• January 2025 - AlphaSights filed a US trademark lawsuit against AlphaSense (see Litigation below)

• August 2025 - AlphaSense announced it was investing over $100 million annually, expanding the Tegus library, adding roughly 7,000 new transcripts a month, reviewed by a 75-person compliance team.

• November 2025 - AlphaSights filed a second, separate trademark lawsuit against AlphaSense - this time in Ireland's Commercial Court (see Litigation below)

• March 2026 - AlphaSense named to Fast Company's "Most Innovative Companies" list in the Enterprise category.

• June 2026 - Alphasense raised $350 million at a $7.5 billion valuation (see Funding below) and announced a strategic partnership with Accenture, alongside Accenture Ventures' investment.

• July 2026 - AlphaSense announced AlphaSummit 2026, a customer conferencing held October 5-7 in New York - the same event later cited in AlphaSights' Irish lawsuit as evidence of ongoing brand confusion.

  Funding & client base

  AlphaSense has raised roughly $1.4 billion in equity financing across multiple rounds:

• March 2016 - $33 million at an unknown valuation, from investors including Tribeca Venture Partners, serving "over 400 investment firms, banks, and corporations globally."

• July 2019 - $50 million Series B, led by Innovation Endeavors, with over 1,000 customers at the time, including more than 50% of the S&P 100 and 33 of the 50 largest investment firms.

• September 2021 - $180 million raised at an unknown valuation, led by Viking Global and Goldman Sachs Asset Management.

• June 2022 - $225 million at a $1.7 billion valuation, led by Goldman Sachs Asset Management and Viking Global, now with 3,500 customers, including 78% of the S&P 100 and 70% of top asset managers and banks. AlphaSense had also discussed a possible IPO around this time, contingent on market conditions improving.

• April 2023 - $100 million at a $1.8 billion valuation, led by CapitalG. At the time they had 4,000 customers.

• September 2023 - $150 million at a $2.5 billion valuation, led by Bond Capital.

• April 2024 - $200 million ARR, more than 4,000 customers, over 80% of the S&P 100.

• June 2024 - Alongside the Tegus acquisition announcement, AlphaSense raised $650 million co-led by Viking Global and BDT & MSD Partners, with participation of Blue Owl (a major GLG lender, lending >$150 million with two vehicles). The deal valued Tegus at $930 million and the combined entity at $4 billion, implying a standalone AlphaSense valuation at roughly $2.42 billion. AlphaSense reported over 4,000 customers at the time; Tegus reported 2,500.

• March 2025 - AlphaSense reported $400 million ARR and 6,000 client firms, including 88% of the S&P 100, with over 150,000 transcripts in the library at the time.

• August 2025 - Multiple interviews with AlphaSense and Tegus executives were published on Sacra, a platform that typically published this kind of content for startups building investor-relations and fundraising narratives - often a signal of a company preparing to raise.

• October 2025 - AlphaSense reported $500 million ARR, 6,500 customers, and 200,000+ transcripts in the library.

• March 2026 - AlphaSense was reported to be seeking "hundreds of millions" in fresh funding, suggesting the company plans to stay private for longer than its earlier two-year IPO timeline (see IPO note below).

• June 2026 - $350 million at a $7.5 billion valuation, with AlphaSense reporting more than $600 million in ARR from over 7,000 client organizations. New investors included Vitruvian Partners, Accenture Ventures, J.P. Morgan Asset Management, D.E. Shaw Ventures, and Pinegrove Opportunity Partners.

On an IPO: alongside the June 2024 funding round, AlphaSense's IPO was rumoured to be roughly two years out, contingent on the company turning profitable and diversifying its client base beyond institutional investors. As of the March 2026 funding-seeking reports, that timeline seems to have shifted - AlphaSense seeking a fresh private round instead suggests it's staying private for longer than originally discussed.

As of mid-2026, AlphaSense's client base includes Adobe, Amazon, American Express, Cisco, J.P. Morgan Chase, Microsoft, Nvidia, Pfizer, and Salesforce, alongside a majority of Fortune 500 companies and most major financial institutions.

AlphaSense pricing

AlphaSense has said seats cost between $10,000 and $20,000 annually, per client testimony reported by Fortune in April 2024. Separately, a 2023 discussion on Reddit put the figure closer to $5,000 - $7,000 per user per year, echoing what we heard from some clients at the time.

Litigation

This section covers legal disputes involving AlphaSense's expert network and transcript library business. Two now-resolved copyright disputes preceded acquisitions; two trademark disputes with AlphaSights remain ongoing.

AlphaSense v. Sentieo (2020-2022). AlphaSense sued Sentieo for copyright infringement in 2020. AlphaSense acquired Sentieo in 2022.

AlphaSense v. Tegus (2023-2024). AlphaSense sued Tegus for patent infringement in September 2023, alleging that Tegus's interface copied features originally developed by BamSEC, which Tegus had acquired roughly two and a half years earlier. AlphaSense stated in court filings that it lost customers and experienced price erosion as a result. Both parties resolved the case on May 8, 2024, without a publicly stated reason. AlphaSense announced its acquisition of Tegus the following month.

This lawsuit and acquisition followed a familiar pattern from when AlphaSense acquired Sentieo in 2022, having first sued it for copyright infringement in 2020.

AlphaSights v. AlphaSense - US case (ongoing). In January 2025, AlphaSights filed a trademark infringement and unfair competition suit against AlphaSense in the US District Court for the Southern District of New York. AlphaSights alleges that the similarity between the two companies' names, and AlphaSense's use of "AS Expert Insights," has caused confusion among clients and experts. In August 2025, the court denied AlphaSense's motion to dismiss key claims, allowing the trademark infringement and dilution claims to proceed toward trial. The parties have until November 16, 2026 to "gather baseline evidence" on their perspectives, and then until April 7, 2027 to complete expert witness discovery, ahead of a scheduled jury trial. No ruling has been issued on the merits of the case.

AlphaSights v. AlphaSense and Tegus Ltd - Irish case (ongoing). In November 2025, AlphaSights filed a separate trademark and passing-off action in Ireland's Commercial Court, naming both AlphaSense Inc. and its subsidiary Tegus Ltd. According to the Irish Times, the filing alleges that AlphaSense's branding - including its "AlphaSummit" conference, held in New York and promoted internationally - has contributed to ongoing brand confusion. AlphaSights is seeking damages and an injunction. As with the US case, these are allegations that have not been adjudicated.

AlphaSense Expert Insights vs. Tegus

Tegus was AlphaSense's closest competitor in the transcript library space before the 2024 acquisition folded it into the same company.

Founded in 2016, Tegus had raised roughly $112 million and separately acquired BamSEC (2021) and Canalyst (2022) in pursuit of becoming a full research platform for institutional investors, competing with the likes of Bloomberg and FactSet - as well as AlphaSense itself.
The two companies' pre-acquisition rivalry included a bitter copyright lawsuit (see Litigation above) before AlphaSense ultimately acquired Tegus at a $930 million valuation, consolidating the two largest players in the expert transcript library industry into one company.
