Pennylane Raised €40 Million to Build What Government APIs Already Provide for Free.
Pennylane raised €40 million in a fundraising round that valued the company at €3.6 billion in January 2026. The government APIs it connects to — net-entreprises.fr for payroll declarations, impots.gouv.fr for tax filings, PSD2 Open Banking for bank account data — have been free and open to any certified developer since 2016. Understanding what that €40 million actually funded changes how you read your monthly invoice.
What the €40 million paid for
Here is how the business works. The French government built machine-to-machine APIs for every major business declaration: DSN (Déclaration Sociale Nominative — the monthly payroll declaration your company files for each employee), DPAE (Déclaration Préalable à l'Embauche — the pre-hiring declaration required before any new hire), and EDI (the electronic format for tax filings). Using these APIs costs software developers nothing per transaction. The certification required to access them is obtainable by any developer who meets the technical specifications.
At €14 to €149 per month, with 800,000 French business customers at an average of approximately €50 per month, Pennylane generates around €40 million per month in recurring revenue — built on infrastructure that costs zero to access. The €40 million raise did not fund the technical infrastructure, because the technical infrastructure already existed. It funded the distribution machine: sales teams, accountant partnerships, marketing campaigns, and a product team to build a friendly interface on top of public APIs. That is the business Pennylane built. That is what your subscription funds.
The number that changes everything
Paying €149 per month for accounting software is a choice. The government API it connects to is free. That is not a technology price — it is a distribution fee.
net-entreprises.fr processes 28 million DSN declarations every month from French employers. The machine-to-machine endpoint any certified software uses to file those declarations is publicly documented, available to any developer who completes the certification process, and costs nothing per submission. Your monthly invoice does not pay for access to that endpoint. It pays for someone else having built the interface first.
Forty years of the same model
Sage has charged French businesses €80-200 per month since the 1980s — same APIs, older interface, similar pricing structure. Cegid reported €967 million in revenue for 2024, acquired EBP that year, and acquired Shine (400,000 customers) in late 2025. Consolidation in this market does not move prices toward zero. It moves market share toward fewer vendors, making the alternative of leaving less convenient.
Telecoms companies charged per-minute rates for decades to access telephone infrastructure that cost fractions of a cent per call to transmit. When alternatives arrived that priced closer to actual cost, the premium subscription model collapsed. Accounting software is on the same arc. The government built the infrastructure. The question is whether someone makes it free to connect to.
The subscription that becomes infrastructure
Your Pennylane bill probably started small. Then payroll was added. Then the accountant integration. Then bank reconciliation via PSD2 — the EU banking regulation that mandates free API access to your account data. Now the entire compliance chain runs through one platform: employee records, DSN filings, VAT declarations, FEC export (the standardized accounting file that tax authorities can demand to inspect within 15 days of starting an audit, with a minimum €5,000 penalty if you cannot produce it). The monthly fee has become a cost of operating.
That lock-in is not accidental. The more of your compliance chain runs through one platform, the higher the cost of switching. Pennylane's most capable tier — the one with full payroll, direct government portal connections, and accountant collaboration — is also the one hardest to leave, because migration means reconfiguring every filing and reconnecting every employee record from scratch. That is the business model venture capital rewards: recurring fees that are difficult to cancel.
What the exit math means for your future invoices
Venture capital invested €40 million in Pennylane expecting 5-10x returns — that is €200-400 million needed back. Those returns come from subscription revenue, sustained or increased across 800,000 customers over time. For an investor holding a share in a €3.6 billion valuation, reducing pricing is not part of the thesis.
Three scenarios worth thinking through. First: Pennylane's tiers reorganize and a feature you currently use moves to a higher tier — this happens regularly in subscription software. Second: a price increase arrives alongside a product update, announced with enough notice to be legal and not enough to be convenient. Third: Pennylane reaches an exit event — IPO, acquisition by one of the European enterprise software groups — and the new owner adjusts subscription terms to meet their own return requirements. None of these is surprising. All three are standard outcomes in subscription software funded by investor capital.
What changes in Q2 2026
Liberté connects to the same government APIs. net-entreprises.fr for DSN. The EDI protocol for tax declarations. PSD2 Open Banking for bank reconciliation. The DPAE filing path for every new hire. All of it, at zero cost to the user.
For any business currently paying €50-149 per month for accounting software, the calculation is simple: before Q2 2026, every invoice is a month of subscription fees for access to infrastructure that is about to be free. Liberté is free the same way Android is free — the platform is infrastructure, open to everyone, and revenue comes from a marketplace of optional paid services where Liberté takes a 30% commission. The accounting and payroll engine costs nothing.
One checkable fact
Visit net-entreprises.fr and go to the developer documentation. The machine-to-machine connection that your accounting software uses to file your monthly payroll declarations is documented publicly, available to any certified developer, and costs nothing per transaction. That is not a claim Liberté is making against Pennylane. It is a public technical specification published by the French government.
None of that monthly fee pays for access to the connection itself. It pays for someone else having applied for the certification first, built the interface on top of it, and marketed it to 800,000 businesses before the free alternative existed. Starting Q2 2026, you have a choice about whether to keep paying for that head start.
