What Verifisaas does
Verifisaas, operated by UK-registered Hitori Tech Limited (Company No. 14860700, incorporated May 2023), is an API-first email verification and deliverability platform headquartered in Harrow, England. The product validates email addresses in real time through a multi-step pipeline covering syntax checks (RFC 5321/5322), DNS/MX record lookup, SMTP handshakes that do not transmit mail, and a risk-scoring layer that evaluates 25+ signals including disposable email providers, spam trap history, role-based accounts, catch-all domain behaviour, and complaint patterns. Supporting modules include a Deliverability Confidence Score (0–100), Domain Intelligence (MX, SPF, DKIM, DMARC, TLS), bulk list processing for 10 to 10 million addresses with webhook delivery, and GDPR/CCPA-aligned data handling with a zero-storage policy and EU data residency.
The platform is distributed primarily through self-serve, product-led signups at app.verifisaas.com, with three pricing tiers — Free (100 verifications/month), Starter ($5/month for 5,000 verifications) and Pro ($15/month for 20,000 verifications) — supplemented by a custom Enterprise tier for customers processing 100k+ emails per day with dedicated infrastructure, SLA guarantees, and DPA documentation. Developer integrations are enabled through a RESTful JSON API and SDKs for Node.js, Python, and PHP, with claimed sub-50ms response times and 99.2% validation accuracy. Target customer segments are horizontal: SaaS and product teams validating signup emails, email marketers running list-hygiene campaigns, and enterprises and agencies with GDPR/CCPA procurement requirements. Operational scale is modest — a 5-person founder-led team including founder Himanshu Verma and co-founder Jyotirmay Gaur — and the business is bootstrapped with no external institutional funding disclosed. The product roadmap signals include SOC 2 Type 2 in progress and a forthcoming blog and documentation suite, indicating an early commercial stage.
