Karza alternatives are other KYB and business verification API providers in India that check a business against sources such as GST, MCA, Udyam, IEC and FSSAI records. Karza Technologies is now part of Perfios, so buyers often compare it with vendors such as Signzy, IDfy, HyperVerge, Surepass, AuthBridge, Bureau and BeFiSc.
Most teams start searching for Karza alternatives at a specific moment: a contract renewal, an integration change after the Perfios acquisition, or a segment, often proprietorships, where hit rates disappoint.
A vendor list does not settle that question. This guide covers what Karza Technologies is today, how the main KYB providers describe themselves, the criteria that separate them, and a seven-step proof of concept you can run on your own files.
What Karza Technologies is today
Karza Technologies is a Mumbai-based provider of business intelligence, verification and lending analytics data for financial institutions. Perfios acquired it in an all-cash deal of USD 80 million (about ₹597 crore), reported by The Paypers on 1 March 2022, with Karza’s founders continuing to run the business under Perfios leadership.
On its current website, Perfios describes itself as an “AI Operating System for Banks – NBFCs – Fintech – Insurance” and lists business onboarding products such as OneClick Onboarding (“One API to fetch all business details to automate MSME Onboarding”), Due Diligence and Compliance Check.
For buyers, the practical point is that “Karza” in a procurement file now usually means a Perfios contract. Contract terms, product names and roadmaps should be confirmed with Perfios directly.
Why teams look for Karza alternatives
The reasons are rarely about one feature. In KYB programmes, they tend to fall into four groups:
- Coverage gaps: strong results on companies, weaker on proprietorships and partnerships with no MCA record.
- Bundling: a team wants KYB alone, or wants KYB
- combined with document checks or bank statement analysis from one vendor.
- Data freshness: the business record returned does not reflect a recent GST cancellation or change of address.
- Second-source policy: risk committees increasingly ask for a fallback vendor on critical onboarding APIs.
None of these is a verdict on any vendor. They are the questions a fair evaluation should answer with your own data.
Karza alternatives for KYB: how vendors position themselves
The table below summarises how each provider describes its KYB or business verification offering on its own website, accessed 7 October 2026. It reflects public positioning only. It makes no claim about pricing, accuracy, performance or customers.
| Vendor | Public self-description (KYB-relevant) |
|---|---|
| Perfios (owner of Karza) | Business onboarding via OneClick Onboarding, Due Diligence and Compliance Check (AML, UBO, PEP) |
| Signzy | “Global Identity Verification and Compliance Platform”; KYB to “verify business legitimacy with registered docs, gov databases, and UBO checks” |
| IDfy | “TrustStack” with OnboardIQ, OneRisk and Privy; lists merchant and business due diligence |
| HyperVerge | Single onboarding stack; KYB with OCR for business registration and tax documents and automated validation |
| Surepass | Onboarding and verification APIs including GST, MCA (CIN/DIN), MSME/Udyam and FSSAI |
| AuthBridge | Vendor due diligence, third-party risk and CorpVeda corporate intelligence reports |
| Bureau | Risk decisioning platform with a Business Verification (KYB) product for marketplaces and fintechs |
| BeFiSc | BizCheck business risk report in about 60 seconds from GST, MCA, Udyam and digital footprint data |
Positioning differs in useful ways. Some vendors sell KYB as one API inside a broad identity stack; others sell a business intelligence report; others embed KYB inside a fraud or risk platform. Decide which model fits your workflow before you compare outputs.
Evaluation criteria for a KYB API
A KYB API is only as good as the sources behind it and how quickly they refresh. Use these criteria when shortlisting Karza alternatives.
| Criterion | What to test | Why it matters |
|---|---|---|
| Source coverage | GST, MCA, Udyam, IEC, FSSAI and others relevant to your segment | Each source covers different entity types |
| Proprietorship coverage | Hit rate on firms with no MCA record | Common among MSME and merchant applicants |
| Data freshness | How a recent GST cancellation or MCA status change appears | Stale “Active” status is a direct fraud gap |
| Latency | Response time at your peak volume | Drives drop-off in assisted and digital journeys |
| Field structure | Normalised legal name, trade name, address, partners or directors | Decides how much matching logic you build yourself |
| Linkage | PAN-to-GSTIN and director-to-company links | Surfaces related entities and repeat applicants |
| DPDP readiness | Purpose limitation, retention, processor terms | Processing of partner and director data falls under the DPDP Act |
| Failure handling | Behaviour when a government source is down | Determines fallback design |
Two of these deserve extra weight. For GST, ask exactly which fields and filing history are returned; our guide to the lists what lenders typically need. For companies and LLPs, check director and charge data against the fields you rely on.
On privacy, the DPDP Rules, 2025 were notified on 14 November 2025 with an 18-month phased compliance timeline, according to PIB. KYB responses often contain personal data of partners, directors and signatories, so processor contracts and retention settings belong in the evaluation, not after it.
Running a side-by-side KYB POC
The fairest way to compare Karza alternatives is to send identical inputs to each vendor and score the outputs against a known answer.
- Build a labelled sample of 200 to 500 recent applications, split across companies, LLPs, partnerships and proprietorships in your real mix.
- Include known bad cases: cancelled GSTINs, struck-off companies, confirmed fraud and mule businesses.
- Fix the input set (PAN, GSTIN, CIN or business name) so each vendor receives the same data.
- Run all vendors in the same time window, so source refresh timing does not distort results.
- Score hit rate, field completeness, status accuracy against your labels, and latency at the 50th and 95th percentile.
- Have two analysts review mismatches blind to the vendor name, and record where each vendor added information the others missed.
- Review DPDP terms, retention, uptime commitments and failure handling before commercial negotiation.
Illustrative scoring rule: weight status accuracy on known bad cases higher than overall hit rate, because missing a cancelled GSTIN costs more than a clean miss on a good applicant.
Where BeFiSc fits: BizCheck returns a business risk report in about 60 seconds from GST, MCA, Udyam and digital footprint data, built for lenders, NBFCs, payment aggregators and marketplaces. BeFiSc will run BizCheck alongside your current KYB vendor on the same sample in a side-by-side POC, so your team can score both on its own labels. BeFiSc reports 99.99% uptime and ISO 27001:2022 certification.
Mistakes buyers make
- Testing only companies: a sample built from MCA-registered firms flatters every vendor and hides proprietorship gaps.
- Using demo data: vendor-provided samples cannot tell you how the API behaves on your applicant base.
- Ignoring the second source: switching vendors without a fallback recreates the single-point dependency.
- Comparing list prices only: the cost that matters is per correct decision, including manual review time.
If KYB is one part of a wider stack review, our list of the covers the identity side.
Key Takeaways
- Karza Technologies has been part of Perfios since the March 2022 acquisition, so evaluations of Karza alternatives usually involve a Perfios contract.
- KYB vendors differ in model: single API, intelligence report, or KYB inside a broader risk platform.
- Source coverage, proprietorship hit rate and data freshness separate vendors more than headline features.
- Run a blind, same-window POC on your own labelled sample, including known bad cases.
- Treat DPDP terms and failure handling as selection criteria, since KYB data includes partner and director personal data.
Frequently Asked Questions
How long should a KYB vendor POC take?
It depends on sandbox access and sample size. Plan time for integration, a same-window run, scoring against labels and blind review of mismatches before any commercial discussion.
What data sources should a KYB API in India cover?
At minimum GST and MCA records, with Udyam for MSMEs. Depending on segment, IEC for importers and exporters and FSSAI for food businesses add value.
What are the main Karza alternatives for KYB in India?
Providers that publicly offer KYB or business verification include Signzy, IDfy, HyperVerge, Surepass, AuthBridge, Bureau and BeFiSc (BizCheck). The right choice depends on your entity mix, sources needed and workflow.
Who owns Karza Technologies?
Perfios acquired Karza Technologies in an all-cash deal of USD 80 million, reported on 1 March 2022. Karza’s founders continued to run the business under Perfios leadership.
Conclusion
Choosing between Karza alternatives is less about finding the best vendor than finding the one whose sources and refresh cycle fit your applicant base. A company-heavy NBFC and a merchant-heavy payment aggregator will reach different answers from the same shortlist.
The teams that decide well test on their own labelled data, weight known bad cases heavily, and keep a second source in production. That approach outlasts any single vendor relationship.
