The short version

  • Each has a real cost: Greenphire the standalone greenphire.com site now redirects to Suvoda and the brands have been integrated, so buyers are contracting with a randomisation and supply vendor and should expect cross selling rather than an independent payments specialist.; Valispace the three-seat minimum means a solo consultant or a two-person startup pays for a seat nobody uses, roughly 3,000 US dollars a year before anyone logs in.
  • They diverge on capability: Greenphire covers ClinCard, Valispace covers Live requirements.
  • 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.

Greenphire

  • The standalone greenphire.com site now redirects to Suvoda and the brands have been integrated, so buyers are contracting with a randomisation and supply vendor and should expect cross selling rather than an independent payments specialist.
  • Nothing is published on price, and the typical shape of a platform fee plus per participant and per transaction charges means the cost of a trial is not knowable until enrolment is known.
  • Payment method availability varies sharply by country, so a global protocol may end up with card payments in some regions and slow manual processes in others, which undermines the retention argument that justified the purchase.
  • Sites bear the administrative work of enrolling participants and triggering payments but are not the buyer, so adoption depends on the sponsor mandating it and site resistance is a real implementation risk.
  • Participant payments create tax reporting obligations that differ per jurisdiction, and the tooling helps but does not remove sponsor liability, so legal and finance review is required in every country the trial runs in.

Valispace

  • The three-seat minimum means a solo consultant or a two-person startup pays for a seat nobody uses, roughly 3,000 US dollars a year before anyone logs in.
  • Ownership has changed twice in two years, from independent to Altium to Renesas by way of the Altium acquisition, and the technology has been repackaged as the Altium Requirements Portal, so the standalone roadmap is genuinely uncertain.
  • It is not a certified DO-178C or ARP4754 toolchain component in the way established requirements databases are, so highly regulated aerospace programmes may still need a recognised tool alongside it.
  • The parametric model rewards teams who structure their data properly at the start; teams that import a flat requirement list get a slower version of a document tool and none of the budget automation.
  • Integration depth outside the Altium and Jira world is limited, so linking to an existing PLM or a CAD-driven mass properties source usually means writing against the Python API yourself.

Answered from the vendors’ own pages

Greenphire: Is Greenphire still sold?

Yes, as Greenphire Patient Payments on the Suvoda platform. The independent website and social presence have been consolidated into Suvoda.

Valispace: Who owns Valispace?

Altium acquired it in December 2023, and Renesas Electronics acquired Altium in 2024. It is therefore a Renesas-owned product, despite frequent reports elsewhere linking it to defence groups.

Greenphire: What is ClinCard?

The reloadable debit card Greenphire issues to participants. Greenphire Patient Payments was formerly known as ClinCard.

Valispace: Is it the same thing as the Altium Requirements Portal?

They share a lineage. Requirements Portal is the Altium 365 packaging of Valispace technology. The standalone Valispace product is still sold with its own pricing.

Greenphire: Does it publish pricing?

No. Pricing is per study and quoted through sales, and funding the payments themselves is separate from the software fee.

Valispace: What does it actually cost?

999 US dollars per user per year with a minimum of three users, billed annually. Enterprise with on-premise deployment is quoted separately.

Greenphire: Can it pay participants outside the United States?

Yes, in more than thirty currencies, but the available payment method depends on the country.

Valispace: Can it replace a requirements database like DOORS?

For small and mid-sized hardware programmes, often yes. For programmes with contractual tool mandates, no.
