DiligenceSquared uses AI, voice agents to make M&A research affordable

TL;DR: DiligenceSquared cuts M&A due diligence costs with AI voice agents and human review

DiligenceSquared shows that commercial due diligence can drop from $500,000, $1 million to about $50,000 by using voice agents for expert interviews and keeping senior humans on final review.

• If you are a founder, this means buyers can check your market story, customer proof, pricing, and growth claims much earlier and much more cheaply.
• The real benefit is not just lower cost. It is faster research, more deal screening, and more pressure on startups to keep clean data rooms and consistent narratives.
• The model works because software handles repetitive research tasks, while humans still judge edge cases, trust, and auditability. You can see that in M&A research automation and the company’s focus on commercial due diligence.

Your takeaway: look at the most expensive expert workflow in your business, split repeatable work from judgment work, and get your company ready for faster buyer scrutiny.

I watch two founder migrations at once in Europe. One moves toward lower burn, smaller teams, and more automation. The other moves toward sectors that used to belong to giant consulting firms, law firms, and banks. DiligenceSquared sits exactly at that intersection. According to TechCrunch’s March 2026 report on DiligenceSquared, private equity firms that once paid $500,000 to $1 million for commercial due diligence can now get similar research workflows done for about $50,000. For founders and business owners, that number matters far beyond mergers and acquisitions. It tells us that one of the most expensive forms of business intelligence is being compressed by software, voice agents, and tightly supervised human review.

I am writing this as a European founder who has built companies in deeptech, edtech, and AI tooling, often with tiny teams punching far above their weight. My bias is clear. I believe small teams should use machines for repetitive research and save human judgment for what humans still do best: framing questions, spotting weak signals, negotiating trust, and making calls under uncertainty. DiligenceSquared is betting that M&A research will follow that rule. And if they are right, consulting economics, private equity workflows, and founder exit preparation will all change faster than many people expect.

Why does DiligenceSquared matter beyond one startup funding round?

DiligenceSquared is a New York startup from Y Combinator’s Fall 2025 batch that focuses on commercial due diligence. In plain English, commercial due diligence means researching whether a target company’s market, customers, pricing, and growth story are real enough to justify an acquisition. This work often sits at the center of private equity deals and larger M&A processes. It is expensive because it usually mixes expert interviews, customer calls, market mapping, analyst work, and a polished report produced by elite consultants.

The company was founded by Frederik Hansen, a former Blackstone principal, Søren Biltoft, who spent seven years in BCG’s private equity practice, and Harshil Rastogi, a former Google engineer. That trio matters. One founder knows how buyers think, one knows how consulting teams package insight, and one knows how to build the machine layer. In March 2026, the company also announced a $5 million seed round led by the funding announcement covered by Morningstar and PR Newswire, with participation from Y Combinator.

Here is why founders should care even if they never plan to buy a company. Commercial research is becoming modular. A task that used to require a famous brand, a huge bill, and weeks of human coordination can now be broken into parts: question design, expert sourcing, interview execution, transcript analysis, synthesis, and report production. Once a workflow can be decomposed like that, software can attack each layer. Then price falls, speed rises, and buyers start asking for research earlier in the process.

That shift has a wider message for startup operators. If elite diligence can be compressed, then a lot of other “premium knowledge work” can also be compressed. I have seen this pattern in startup education, IP workflows, and founder support systems. The winners are rarely the teams that remove humans entirely. They are the teams that place humans only where judgment, nuance, and accountability truly matter.

What exactly is DiligenceSquared selling?

The company sells a faster and much cheaper version of the research layer inside M&A and private equity decision-making. Instead of staffing large consultant teams to interview target-company customers and market participants, DiligenceSquared uses voice agents to run many of those conversations and then turns the responses into structured findings. Pulse 2’s summary of the company workflow adds useful detail: the system starts with a research blueprint, sources relevant experts, runs multilingual interviews, synthesizes findings, and then produces interactive reports with traceability back to interview transcripts.

That last point is more important than it looks. In serious diligence, the output is not just a slide deck. Buyers need to know why a conclusion was reached, which evidence supports it, and whether the chain of reasoning can be audited. If a platform cannot show source traceability, many deal teams will not trust it. That is why the hybrid model matters. TechCrunch reported that senior human consultants verify the final output, which helps the company defend quality where buyers feel the most legal and financial risk.

• Traditional model: consulting teams interview dozens of market participants, combine that with market data, and produce long reports for PE firms.
• DiligenceSquared model: software handles much of the interview and synthesis workload, while senior humans review and validate findings.
• Price claim: about $50,000 versus the $500,000 to $1 million often charged by McKinsey, Bain, or BCG for similar diligence work.
• Timing advantage: funds can run diligence earlier, before they have very high conviction in a deal.
• Volume effect: firms may screen more deals because the cost of being wrong falls.

Why is the price drop such a big deal for M&A and private equity?

Because diligence cost shapes behavior. When research costs up to a million dollars, buyers become selective about when they commission it. They wait until a deal looks likely. They narrow the funnel. They avoid spending on lower-confidence targets. That means many interesting companies never get the same depth of scrutiny as headline deals. Once the price falls by roughly 90%, behavior changes.

Frederik Hansen told TechCrunch that PE firms are now more willing to engage DiligenceSquared earlier in the process. That single point tells me the product is not just a cheaper vendor. It changes the timing of decision-making. In startup terms, this is similar to what no-code tools and AI agents did for prototyping. When the cost of testing falls, teams run more experiments. When the cost of diligence falls, investment teams inspect more targets.

That can reshape the mid-market and lower mid-market deal economy. Smaller funds that could never justify repeated blue-chip consulting bills can now get access to research that was once reserved for giant funds and billion-dollar buyouts. Founders selling companies into that market may face more data-backed questions, earlier requests for customer access, and faster screening cycles. The gatekeeping function moves from brand-name consultants toward process design and evidence quality.

As a founder, I find that both promising and uncomfortable. I like lower barriers. I also know that once research gets cheaper, buyers often ask for more of it, not less. So while DiligenceSquared may reduce cost pain for acquirers, it could also raise expectations for target companies that are not ready with clean data rooms, customer references, and consistent commercial narratives.

How do AI voice agents fit into commercial due diligence?

Let’s make this concrete. A voice agent in this context is software that can hold a spoken interview, ask follow-up questions, capture the answers, and convert those answers into analyzable text. In due diligence, that means speaking with customers, former customers, industry operators, or other market experts. The goal is to learn whether a target company really has pricing power, customer love, product stickiness, and defensible growth.

This matters because interviews are usually the hardest part to scale. Reading documents is one thing. Talking to people, probing nuance, and collecting enough interviews for pattern recognition is another. Voice agents attack the most labor-heavy piece. Pulse 2 described the company’s pitch as a way to run dozens or even hundreds of interviews at the same time, which removes a classic bottleneck in consulting-led diligence.

I have built learning systems and founder tooling where language is not just content, but interface. My linguistics background makes me very alert to one thing here: question quality decides answer quality. A voice system can be fast and still ask bad questions. It can sound smooth and still fail to surface signal. So the real moat is not “we have voice AI.” The moat is whether DiligenceSquared can design interview flows that produce commercially meaningful evidence and then separate genuine insight from polite noise.

• Good use of voice agents: high-volume, structured interviews where the same themes must be tested across many respondents.
• Weak use of voice agents: very delicate, politically sensitive conversations where trust and subtle negotiation matter more than scale.
• Best hybrid setup: software handles the first pass, while senior humans review edge cases, contradictions, and high-stakes conclusions.

What does this say about the future of consulting economics?

It says that the old consulting bundle is under pressure. For years, buyers paid for a package that mixed brand trust, analyst labor, expert network access, interview orchestration, synthesis, and board-ready presentation. Software can now unbundle several of those layers. If software handles sourcing, calling, transcription, coding, pattern extraction, and report drafting, then the buyer starts asking a brutal question: what exactly am I paying the premium humans for?

The honest answer is still meaningful. Buyers pay humans for judgment, reputation, liability comfort, and the ability to defend a recommendation in a boardroom. Yet that does not protect the whole fee pool. It only protects the layers that software cannot easily copy. So I expect the consulting market to split into three bands.

• Band 1: software-heavy diligence for fast screening and mid-market deals.
• Band 2: hybrid diligence where software does the groundwork and humans own interpretation.
• Band 3: premium advisory work for the most political, complex, or high-value deals.

DiligenceSquared is clearly aiming at Band 2, with pricing that makes Band 1 accessible too. That is smart. Going fully machine-only would scare buyers. Staying too human-heavy would weaken the cost gap. The middle zone is where many high-value B2B AI companies will make money in 2026.

I have a strong founder bias here. I do not believe “automation” wins because it removes people. It wins because it reassigns expensive human attention. If I can take a specialist who used to spend 40 hours gathering and cleaning evidence, and move that person into 40 hours of interpretation and decision support, the service gets cheaper and often better. That is the actual commercial logic behind DiligenceSquared.

Who are the main competitors and what does the market signal say?

TechCrunch named Bridgetown Research as the main competitor, and that matters because investors are already funding this category aggressively. The publication pointed to Bridgetown Research’s $19 million Series A covered by TechCrunch, co-led by Accel and Lightspeed. When one startup in a category raises $5 million seed and another pulls in $19 million Series A, the message is simple: investors think due diligence is a large enough market, painful enough, and repetitive enough to support multiple winners.

There is also a nearby category worth watching. DiligenceSquared is not the same as consumer research startups, but the overlap is real. The article referenced players like Listen Labs, Keplar, and Outset. The difference is domain specificity. Consumer research asks broad product and market questions. Commercial due diligence asks whether someone should risk huge amounts of capital on an acquisition. The tolerance for errors is far lower.

That means category winners will likely need four things at once:

• Strong workflow design, not just flashy models.
• Traceability, so every claim can be checked against source material.
• Human review, especially in high-stakes deals.
• Buyer trust, which often comes from founder credibility and early client logos.

DiligenceSquared has at least two of those on day one: founder credibility and early client access. Former Blackstone and BCG backgrounds are not decorative here. They tell buyers, “we know how this work is judged from the inside.” That makes sales easier in a conservative market.

What can founders and business owners learn from DiligenceSquared right now?

A lot, even if you never touch private equity. I teach founders to treat startups as structured games of information gathering. Cheap tests beat expensive guesses. DiligenceSquared applies the same logic to M&A. It takes a process known for elite labor cost and asks which parts can be turned into repeatable systems. That question should be asked in almost every company.

1. Which expensive expert workflow in your business can be decomposed?

Many founders look at a high-cost service and think the whole thing is untouchable. Wrong starting point. Break the workflow into pieces. In due diligence, those pieces include expert sourcing, interview scheduling, interview execution, synthesis, and reporting. In your company, the pieces may be lead qualification, proposal drafting, training, support triage, or compliance checks.

2. Can software handle the repetitive layer while humans keep the judgment layer?

This is the model I trust most. In my own work, whether in founder tooling or startup education, I push routine scaffolding toward software and keep narrative, ethics, strategy, and hard calls with humans. DiligenceSquared appears to follow the same rule. That is one reason their pitch feels commercially plausible rather than naive.

3. Are you prepared for buyers who can research you faster and cheaper?

If you plan to raise, partner, or exit, assume that counterparties will soon have lower-cost ways to pressure-test your story. You need cleaner customer references, tighter churn explanations, better pricing logic, and stronger documentation. The old trick of surviving because diligence was too expensive for smaller buyers is fading.

4. Does your team confuse speed with trust?

Faster output is useful only when the evidence chain stays credible. Founders often ship fast and skip proof. In B2B markets, that is dangerous. DiligenceSquared’s human-reviewed final layer is a reminder that trust is designed, not assumed.

How should founders prepare for an AI-shaped due diligence world?

Next steps. If I were advising a founder planning a raise or a strategic exit in 2026, I would tell them to prepare as if every investor or acquirer now has a cheap research machine sitting beside them. That does not mean panic. It means better operating hygiene.

1. Audit your customer proof. Make sure your references are real, reachable, and consistent. If ten customers were interviewed tomorrow, would their stories line up on product value, switching cost, and pricing?
2. Clean your revenue narrative. Be ready to explain concentration risk, churn, expansion revenue, and seasonality without contradictions.
3. Prepare your market map. Define your segment clearly. Do not let buyers define your category for you. Ambiguity kills valuation.
4. Build a traceable data room. Contracts, retention data, pricing, cohort data, and major customer case studies should be easy to verify.
5. Train your team for interviews. Sales leaders, product leaders, and customer success managers should know how to answer diligence questions without improvising nonsense.
6. Pressure-test your own company first. Run internal mock diligence before the real process starts. I do this in startup education all the time. Slight discomfort now saves real damage later.

That last point matters. One of my operating beliefs is that learning should be experiential and slightly uncomfortable. Real diligence is uncomfortable. It exposes weak logic, messy data, and stories founders tell themselves because no one forced precision earlier. Better to surface that in rehearsal than in a live transaction.

What are the biggest mistakes people will make when reading this trend?

I see at least five.

• Mistake 1: Assuming software replaces trust.
  It does not. It changes how trust is produced. Traceability and human review still matter.
• Mistake 2: Believing all knowledge work will become cheap.
  No. The repetitive layer gets cheaper first. The judgment layer often becomes more valuable.
• Mistake 3: Thinking this only affects private equity.
  No. It affects fundraising, partnerships, vendor selection, lending, insurance, and strategic planning.
• Mistake 4: Copying the surface, not the method.
  Adding a voice bot to a messy workflow solves very little. Workflow design is the business.
• Mistake 5: Ignoring founder readiness.
  As buyer tools get stronger, startup sloppiness gets punished faster.

What is my founder take on DiligenceSquared’s chances?

I think the company has a real shot because it picked a painful, high-ticket workflow with clear economic waste and measurable output. That is a much better place to build than a vague “general business assistant.” The founders also have category credibility, which is priceless when selling to conservative financial buyers.

My caution is about execution discipline. In markets like this, teams often get seduced by demo quality. The client hears a polished voice, sees a neat dashboard, and everyone starts talking about speed. But due diligence is not a beauty contest. It is an evidence contest. The startup that wins will be the one that is hardest to fool, easiest to audit, and most consistent across messy real-world projects.

I also think Europe should pay close attention. We have deep pools of finance, legal work, industrial M&A, and cross-border mid-market transactions. We also have many smaller funds and founder-led businesses that cannot justify giant consulting bills. A product like this is well suited to that environment. And for European founders, this is another reminder that you do not need to attack only consumer apps or developer tools. Some of the best AI companies now target old, expensive workflows hidden inside boardrooms.

What should entrepreneurs do with this insight?

Take the lesson seriously. DiligenceSquared is not just a startup story. It is a market signal. The signal is that buyers will pay for software that compresses expensive research, provided the result stays credible. If you are a founder, freelancer, or business owner, ask yourself where you still depend on prestige-priced human labor for repetitive information work.

1. List the workflows in your business that cost the most expert time.
2. Split each workflow into repeatable steps and judgment-heavy steps.
3. Push the repeatable steps toward software, templates, or agents.
4. Keep humans responsible for interpretation, accountability, and sensitive calls.
5. Prepare your company to be examined by faster, cheaper diligence tools.
6. Build proof, not just narrative.

That is the part many founders miss. AI does not just help you work faster. It also helps other people inspect you faster. If you are building for acquisition, raising capital, or trying to win enterprise clients, that changes the game. And if you want to build your own company in this wave, the best targets may be hidden inside old premium services where the bill is high, the workflow is repetitive, and the trust layer can still be supervised by humans.

I have spent years building systems for founders who do not have giant budgets, giant teams, or giant margins for error. My rule stays the same: use machines as your first team for research and scaffolding, but never outsource judgment. DiligenceSquared appears to understand that. That is why I think this company is worth watching in 2026.
