I built Searcher OS, so read this with that in mind. I'll keep the comparison honest anyway — buyers talk to each other, and a misleading comparison page costs more than it earns.
This page compares the tools relevant to buyers targeting businesses in the $800K to $8M range — self-funded searchers, funded search, micro-PE, and family offices. The short version: most tools solve one or two of the five workflow problems (sourcing, screening, pipeline tracking, financial analysis, document review). Very few solve all five.

The full acquisition operating system: deal sourcing from marketplaces plus 300+ regional broker sites, buy box matching, Kanban pipeline CRM, AI CIM analysis, SBA and DSCR calculators, and broker outreach automation in one place.
A strong deal aggregation search engine with a very large listing index and AI summaries. Sourcing only — no CIM analysis, no financial calculators, basic pipeline at higher tiers.
Software-plus-advisory platform: AI search across marketplaces, pipeline tools, Plaid buyer verification, and managed tiers where a human team runs outreach for you. Pricing now requires a sales call.
The largest business-for-sale marketplace. Great raw listing volume, but it is one source with no buy box matching, no CRM, no CIM analysis, and no deal math — the workflow is on you.
Where most searchers start: BizBuySell bookmarks, a Google Sheet pipeline, and Gmail labels. Works for casual browsing, breaks down once you are reviewing 10+ deals a week.
Just exploring? Start free. Browse BizBuySell, try Kumo's free tier or the Searcher OS Free plan, and calibrate your buy box before paying for anything.
Running a systematic search? Reviewing 10+ deals a week with NDAs outstanding is where spreadsheets break down. An integrated platform pays for itself in recovered hours — that's the profile Searcher OS was built for.
Want to outsource the search? ClearlyAcquired's managed tiers put a human team on your sourcing. Budget for a retainer plus success fees.
Want the head-to-heads? See Searcher OS vs Kumo and Searcher OS vs BizBuySell, or the long-form 7-tool comparison on the blog (covers Axial, SourceCo, and SMBmarket too). And before you pay for anything, the free calculators — including the SBA loan calculator — work without an account.
For self-funded searchers buying businesses in the $800K to $5M range, Searcher OS provides the most integrated workflow — deal sourcing, buy box matching, pipeline CRM, AI CIM analysis, and SBA loan modeling in one platform. Kumo is strong for raw deal volume, ClearlyAcquired offers managed service tiers, and BizBuySell remains the largest single marketplace to browse.
For searchers reviewing 10+ deals per week, yes. The manual approach (BizBuySell + spreadsheets + email) works for low-volume exploration but breaks down at scale. Purpose-built software saves 5 to 10 hours per week in aggregation, screening, and pipeline management — time that converts directly into more deals evaluated.
Deal sourcing software finds listings — it aggregates broker sites and marketplaces into one feed. Deal management software tracks your pipeline: NDAs, CIMs, LOIs, and stage progression. Most searchers need both. Searcher OS integrates both; Kumo focuses primarily on sourcing; BizBuySell is a single marketplace with neither.
Yes. BizBuySell is free to browse, Kumo has a free tier, and Searcher OS has a free-forever plan (full deal feed on a 3-week delay, 1 buy box, 1 AI CIM analysis a month, no credit card). Free options are sufficient early on; the limitations show up when you need buy box matching, pipeline tracking, and financial analysis in the same workflow.
There is a Free plan with no credit card required: the full deal feed (listings shown once they are 3 weeks old), 1 buy box, and 1 CIM analysis a month. The Searcher is $79/month ($759/year) for the full operating system with fresh, real-time listings, and there is a Deal Team plan for teams. Paid plans start with a 7-day trial.
Free plan, no credit card. Set a buy box, watch the feed fill, and run 1 CIM through the AI analyzer before you pay anything. Upgrade to Searcher ($79/mo) for fresh, real-time listings.
