SalesUltra: only pay for leads that are real.
B2B lead enrichment and cold outreach platform. Search contacts, enrich with triple-verified emails, and push directly into email campaign tools — pay only for valid data.
The Problem
Sales teams waste hours copy-pasting between lead databases, email verification tools, and campaign platforms. They pay for stale data, bounce rates eat their sender reputation, and there's no unified workflow from “find a lead” to “send a cold email.” They needed one platform that handles the entire pipeline: search → verify → enrich → push to campaign.
The Solution
I built SalesUltra as a full SaaS product: a B2B lead enrichment platform with integrated campaign tools, credit-based billing, and a “pay only for valid data” model that aligns costs with results.
Lead Search
Search a database of B2B contacts via the A-Leads API with granular filters: job title, company size, location, industry, technologies, and domains (with include/exclude logic). Results display in a paginated table. Save results into named lead lists stored in Supabase. Saved searches can be reloaded.
Lead Enrichment
Batch-enrich leads to find triple-verified email addresses. Processes in batches of 5 with retry logic, skips already-enriched leads, and fetches additional pages from the search API if the current list runs out. Two-phase progress bar (“Fetching” → “Enriching”). Credits are consumed only for successful email finds — no charge for misses.
Campaign Integration
Push enriched leads directly into Instantly or PlusVibe campaigns. API keys are validated server-side via Edge Functions. Campaigns are fetched from the connected workspace and leads are sent in one click. Duplicate checking across all lead lists prevents sending the same person twice.
Subscription & Credits
Three Stripe-managed tiers: Ignite ($99/mo, 6K credits), Boost ($149/mo, 12K credits), Power ($249/mo, 30K credits). Credits tracked in real-time with full transaction history. Periodic subscription verification via Edge Function. Users without a plan are redirected to the plan selection page.
