Best for: An operator with customer-research chops and enough SaaS fluency to read a cohort table
The ideaWhat this actually is
A specialized service for people buying small software businesses. Before the wire, a fixed-fee diligence sprint runs structured interviews with a sample of the target's customers, scores churn risk per key account, and assesses dependence on the founder, delivering a plain-spoken report with a walk-away recommendation when warranted. After closing, a first-90-days retention program, playbooks plus weekly coaching, keeps customers from leaving when the founder does. It works for buyers only, never both sides of a deal.
The opportunityWhy this idea works
Thousands of small SaaS products change hands yearly through marketplaces and brokers, and diligence stops at the dashboard: revenue charts, churn curves, code review. Nobody talks to the customers, so buyers discover after closing that the top accounts were personal loyalists of the founder, already shopping alternatives. Customer-level truth before the wire, and customer retention after it, are both purchasable services nobody is selling. Buyers of $50,000 to $500,000 businesses can afford a few thousand dollars for the truth, the transition program is a warm second sale, and the whole deal-flow market sits in a few rooms.
The openingWhy this idea is overlooked
Diligence culture fixates on financials and code because those are legible, while customer interviews require research chops and confidentiality choreography most buyers and advisors lack. The market is small-dollar per deal, so brokers and big advisors ignore it. An operator with customer-research chops and enough SaaS fluency to read a cohort table can own the customer-truth layer of small-SaaS M&A.
The buildWhat you need to build this
| You need | Why it matters |
|---|---|
| A productized diligence sprint | A fixed-fee, fixed-timeline package, structured customer interviews, churn-risk scores per key account, founder-dependency assessment, and a plain report with a walk-away recommendation, so buyers know exactly what they get. |
| Interviews that surface what dashboards hide | Customers reveal whether they stay for the product or the founder's support, what they would switch to tomorrow, and unbuilt promises, so a consistent interview guide makes findings compare across deals. |
| Confidentiality choreography | Mid-deal customer contact is delicate, so working under NDA, coordinating messaging with the seller, and framing conversations as product-feedback research is why brokers refer you rather than fear you. |
| A first-90-days transition program | The first ninety days decide retention: founder goodbye done right, outreach to at-risk accounts from the interview map, support continuity, early wins, sold as playbooks plus weekly coaching, priced monthly. |
| Deal-flow distribution | Acquisition marketplaces, micro-PE communities, brokers, and buy-side courses and newsletters are the whole market in a few rooms, and one public post-mortem of what interviews caught establishes the category and your name. |
| Clear conflict lines | Working for buyers only, never both sides, and disclosing broker relationships, because in a small ecosystem your independence is the asset and one compromised report ends the firm. |

Questions
What people ask about this idea
What does the diligence sprint actually find?
What the dashboard hides: whether top accounts stay for the product or the founder's personal support, what they would switch to tomorrow, and founder dependency, via structured customer interviews with a walk-away recommendation when warranted.
Won't contacting customers spook the deal?
Not if handled right. You work under NDA, coordinate messaging with the seller, and frame conversations as product-feedback research, which is exactly why brokers refer you rather than fear you.
What is the transition program?
A first-90-days retention plan, founder goodbye done right, outreach to at-risk accounts from the interview map, support continuity, and early wins, sold as playbooks plus weekly coaching, priced monthly.
Do you ever represent sellers?
No. You work for buyers only, never both sides, and disclose any broker relationship, because in a small ecosystem your independence is the asset and one compromised report ends the firm.
How is it priced?
A fixed-fee sprint in the range of roughly $2,000 to $7,500, affordable for buyers of $50,000 to $500,000 businesses, plus a monthly transition program as the second act.
