7 Best Improver Alternatives for B2B Enrichment in 2026

SyncGTM is a B2B enrichment platform best suited for outbound teams that need high coverage rates and automated pipeline workflows, offering waterfall enrichment across 50+ providers at $89/mo (annual) with a free tier.

Where Improver runs a single LinkedIn-anchored source and caps you at 500 credits per month, SyncGTM runs a waterfall — sequencing through provider after provider until a verified result lands, and only charging on success. That lifts contact coverage from the single-source 40–60% hit rate to 80%+ across most ICPs, eliminating the coverage wall that defines Improver's limit.

The data depth gap is significant. Improver returns personal emails and phone numbers from LinkedIn profiles. SyncGTM returns 76+ fields per record: verified business email, mobile direct dial, company firmographics, technographics, funding stage, headcount, LinkedIn URL, job title history, and buying signals like recent funding rounds, job postings, and technology installs.

SyncGTM's AI agents handle the workflow piece Improver omits entirely — triggering enrichment on CRM events, firing outreach sequences when buying signals match, and routing leads automatically to the right rep or sequence. That replaces the three-tool stack (Improver + CRM exporter + sequencer) most users maintain alongside their Improver subscription.

SignalHire is a contact finder best suited for recruiters and SDRs who need a LinkedIn Chrome extension with a larger profile graph than Improver, offering email and phone reveals from 400M+ profiles with an annual plan starting around $69/mo.

SignalHire is the most direct Chrome-extension upgrade from Improver. Both work inside LinkedIn profiles and return personal and business contact data in one click. SignalHire's key advantage is database size: 400M+ social media profiles worldwide versus Improver's narrower index, meaning fewer blank returns on the same search. SignalHire also combines email and phone in a single reveal where Improver sometimes requires separate credits.

The main tradeoff is price. SignalHire's annual plan runs significantly higher than Improver's $15–$80/year range. And like Improver, SignalHire runs a single database — there is no waterfall fallback when its data doesn't reach a contact. No native sequencing or CRM automation is included either.

Apollo.io is an all-in-one sales intelligence platform best suited for SMB and mid-market outbound teams, offering a 275M+ contact database with built-in sequencing and intent data starting at $49/mo.

Apollo is the biggest jump from Improver in terms of capability. Where Improver extracts personal emails from LinkedIn profiles at up to 500 credits per month, Apollo offers 275M+ searchable contacts, 150 free email credits and 50 mobile credits per month, built-in email sequences, LinkedIn task steps, and buyer intent signals — all in one platform. If a team is manually exporting Improver CSVs into a sequencing tool, Apollo collapses that into a single workflow.

The tradeoff versus Improver is price per credit at low volume. Improver's $15/year plan works for a solo rep doing occasional outreach. Apollo's $49/mo Basic plan makes sense once a team is running consistent outbound volume. For any team of two or more SDRs with a real pipeline motion, Apollo outperforms Improver on every meaningful metric.

Hunter.io is a domain-based email finder best suited for teams prospecting by company name rather than LinkedIn profile, offering email discovery with confidence scoring and built-in campaign features starting at $34/mo.

Hunter takes a fundamentally different approach from Improver. Where Improver starts with a LinkedIn profile and extracts personal contact data, Hunter starts with a company domain and surfaces work emails using pattern detection, public web sources, and a large email index. Hunter's domain search returns all known email addresses associated with a domain — useful for accounts where you know the company but not the specific contact.

Hunter's confidence scoring is a meaningful differentiator. Every email gets a percentage score indicating deliverability likelihood — so teams can filter for high-confidence sends and avoid bounces that damage domain reputation. Improver returns addresses without verification confidence data. Hunter also includes built-in email campaigns and a basic CRM, adding outreach capability Improver doesn't have.

RocketReach is a contact-lookup platform best suited for reps who want to look up contacts by name or LinkedIn URL against a much larger database than Improver, offering 700M+ profiles with email and phone reveals from $39/mo.

RocketReach is the closest workflow match to Improver at larger scale. Both accept a name or LinkedIn URL and return contact data. RocketReach's advantage is raw database size: 700M+ profiles versus Improver's narrower index, which means significantly fewer empty returns on the same contact searches. The browser extension works on LinkedIn profiles in the same single-click pattern Improver users are familiar with.

The tradeoffs are limited firmographic depth and no native sequencing. RocketReach returns email and phone data reliably, but company-level intelligence (tech stack, funding, headcount growth) is thin compared to a full sales intelligence platform. And like Improver, there is no waterfall — when RocketReach's graph doesn't reach a contact, the search ends empty.

Snov.io is a multichannel lead generation platform best suited for small teams that want email finding, verification, drip campaigns, and LinkedIn automation in one affordable subscription, starting at $30/mo.

Snov.io is the most complete bundle on this list at a price point close to Improver. Where Improver is purely a contact extractor, Snov.io combines a domain email finder, a LinkedIn Chrome extension, email verification, drip email campaigns with personalisation, and LinkedIn automation into one platform. Integration with 5,000+ third-party tools via native connectors and Zapier handles the CRM push that Improver users do manually.

The tradeoff is database depth. Snov.io's contact graph is smaller than Apollo or RocketReach, and phone number coverage is thinner than dedicated dialers. For teams where email outreach is the primary motion and budget is tight, Snov.io's bundled approach offers far more than Improver at a comparable total cost.

Lusha is a contact-lookup tool best suited for reps who want the simplest possible LinkedIn Chrome extension with a usable free tier, offering paid plans from $22/mo (annual) and ~70 free credits per month.

Lusha is the Improver alternative that feels most familiar in use. Both are Chrome extensions that surface contact data on LinkedIn profiles in one click — same motion, same speed, same simplicity. Lusha's advantages over Improver are a larger database, stronger North American direct-dial coverage, a more generous free tier (~70 credits vs Improver's 3), and a GDPR compliance framework that makes work emails safer for cold outreach than Improver's personal-email focus.

The limits mirror Improver's. Lusha runs a single source with no waterfall fallback, coverage thins outside North America, firmographics are light, and there is no native outreach or sequencing. For teams that want Improver's exact simplicity with more credits and better compliance, Lusha is the natural next step.
