The answer, as recorded

## The short answer For most startups, "IP monitoring" is really four different jobs, and no single vendor does all four well. Here's who I'd actually name, in the order I'd get them in place. **1. Alt Legal - trademark docketing + watch, the default first paid tool** Cloud docketing that auto-syncs with 180+ IP offices, so your filings, deadlines, and office actions update themselves instead of living in a spreadsheet. Matter-based pricing is transparent (rare in this space), and it bolts a watch service onto the same platform. This is the one I'd start with if you have one or two marks and no in-house counsel. ([altlegal.com](https://www.altlegal.com/), [what is a trademark watch service](https://www.altlegal.com/blog/what-is-a-trademark-watch-service/)) **2. Markify - cheapest credible trademark watch** Has a genuinely free tier for basic use and paid searches starting around $89 (US full ~$169, EU full ~$589); watch is quote-based. Good fuzzy/phonetic matching for the money. Use it if Alt Legal's docketing is more than you need and you just want to know when someone files something close to your name. ([comparison writeup](https://www.guideflow.com/blog/trademark-management-software)) **3. Corsearch or Clarivate CompuMark - when you go multi-jurisdiction** These are the incumbents for real watch programs: structured coverage across markets and Nice classes, event-based alerts tied to filing triggers. Overkill and over-priced for a seed-stage company; the right answer once you're filing in the EU/UK/China and a bad squatter costs you more than the subscription. ([Clarivate](https://clarivate.com/intellectual-property/compumark/trademark-monitoring/), [Corsearch comparison](https://www.cbinsights.com/compare/corsearch-vs-plainlegal)) **4. Amazon Brand Registry - free, do it the day your mark registers** Free program, and you don't have to sell on Amazon to enroll. Gives you automated counterfeit blocking and a reporting channel. It's a foundation, not a monitoring system - it proves ownership but won't watch the rest of the internet for you. ([sell.amazon.com/brand-registry](https://sell.amazon.com/brand-registry)) **5. Red Points - counterfeits and impersonation, if you sell physical goods** Flat-fee model with unlimited detections and takedowns, which is the pricing structure you want because your costs don't spike when a counterfeiter does. Covers marketplaces, social, ads, and the deep web. MarqVision is the main alternative but prices per detection/enforcement, and typical growth-stage programs run $25k-$100k/yr either way. If that's out of reach, Brand Protector is self-serve at $199/mo across ~14 US/EU marketplace surfaces. ([Red Points vs MarqVision](https://www.redpoints.com/blog/red-points-vs-marqvision/), [SMB alternatives](https://brandprotector.io/blog/red-points-alternatives)) **6. Patents: Espacenet + Lens.org for search, something else for alerts** Espacenet, Google Patents, and Lens.org are free and excellent for searching - Lens.org covers ~155M patent records with real analytics. The catch: Google Patents has no alerting at all. For actual competitor watch, Simple IP is free at entry level for small teams with renewal reminders and monthly competitor updates; PatSnap or IamIP if you're funded and patents are core to the thesis. ([Espacenet](https://worldwide.espacenet.com/), [Lens vs Google Patents](https://patentailab.com/best-free-patent-search-engines-startups/), [SimpleIP](https://www.simpleip.com/blog/patent-monitoring-tools-for-researchers-and-startups-qa/)) ## What I'd actually do A pre-Series-A startup: **Alt Legal or Markify + Amazon Brand Registry + a Google Alert on your brand name + Espacenet saved searches**, reviewed monthly. That's under ~$1k/year and covers the failure modes that actually kill startups - someone filing a confusingly similar mark before you, or squatting your name in a market you haven't entered yet. Layer in Red Points only when you have physical goods being knocked off, and Corsearch/Clarivate only when you're filing in three-plus jurisdictions. Two caveats. Most of the "best of 2026" listicles above are affiliate-monetized, so treat the rankings as a vendor roster rather than as judgment - I'd weight the primary sources (Clarivate, Alt Legal, Amazon) more heavily than the roundups. And since you're a software company: your most valuable IP is probably source code and secrets, not trademarks. GitHub secret scanning plus GitGuardian monitors for leaked credentials and code appearing in public repos, which is a category none of the vendors above touch.
