The short version

  • Only Clearbit has a free tier, so it costs nothing to try first.
  • Each has a real cost: Alvaria the October 2025 restructuring wrote off more than 75% of roughly $950 million of debt and handed control to a lender group led by Nut Tree Capital, so the owner is now a credit fund optimising for debt recovery rather than a growth investor, which is a real signal about future research spending.; Clearbit pricing can be expensive at scale with usage-based model
  • They diverge on capability: Alvaria covers Compliant outbound dialling, Clearbit covers Company enrichment.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Alvaria

  • The October 2025 restructuring wrote off more than 75% of roughly $950 million of debt and handed control to a lender group led by Nut Tree Capital, so the owner is now a credit fund optimising for debt recovery rather than a growth investor, which is a real signal about future research spending.
  • The September 2024 spin-out of the workforce management suite to the revived Aspect brand means a buyer who wanted an integrated CX plus WFM stack now signs two contracts with two companies, and first-party integration is no longer guaranteed by a single roadmap.
  • Digital channels are underbuilt: reviewers report CXP has no support for WhatsApp, RCS or Viber, and no ability to bring your own carrier for email and SMS, which blocks messaging-first and many international deployments.
  • Legacy on-premise upgrades are described by reviewers as long and painful, with a large footprint and hard-to-learn interdependencies, so migration cost is a substantial hidden line item on any modernisation.
  • Alvaria is slower than peers to certify new Nuance speech recognition and text-to-speech releases, so speech quality in your IVR runs behind whatever the underlying engine has shipped.
  • There is no published pricing, no trial and a mixed on-premise and cloud licensing model, making like-for-like comparison against Genesys, Five9 or NICE genuinely difficult and lengthening the evaluation.

Clearbit

  • Pricing can be expensive at scale with usage-based model
  • Batch enrichment has per-row cost that adds up quickly for large datasets
  • Limited data for smaller or private companies
  • Now integrated into HubSpot as Breeze Intelligence, may affect standalone availability

Answered from the vendors’ own pages

Alvaria: Was Alvaria renamed to Aspect?

No. It split. Aspect is the spun-out workforce management business at aspect.com. Alvaria kept outbound and contact centre infrastructure. Confusing the two points procurement at the wrong vendor.

Clearbit: Does Clearbit offer a free tier?

Yes. The first 50 real-time lookups are free. After that, usage-based pricing applies with 500 free credits included in subscription plans.

Alvaria: Who owns Alvaria now?

Since October 2025, a lender group led by Nut Tree Capital, following an out-of-court debt restructuring. Abry Partners no longer controls the company.

Clearbit: How does Clearbit batch enrichment pricing work?

Batch enrichment costs $0.30 USD per row, with totals rounded to $5 increments. Bulk batch discounts are not available, but large volumes can negotiate lower rates through monthly/annual subscription to the Enrichment API.

Source
Alvaria: Can I still buy on-premise?

Yes. Cloud, on-premise and hybrid deployments are all offered, which is one of the few remaining reasons to choose Alvaria over a pure CCaaS vendor.

Clearbit: What data does Clearbit provide?

Clearbit maintains information on over 20 million companies with over 100 rich attributes including demographic and technographic data, industry classification, and company size information.

Source
Alvaria: Does it support WhatsApp or RCS?

Not per current reviewer reports on CXP. Voice and some SMS only, with no bring-your-own-carrier option for email and SMS.

Clearbit: Is there an API available?

Yes. Clearbit offers REST APIs for real-time enrichment and bulk batch processing, allowing direct integration into applications and workflows.
