Kabilio
TLDR: An AI accounting copilot on Spain's Verifactu mandate. The compliance badge is table stakes; the pricing pages reveal a two-sided wedge: throughput pricing for accounting firms plus a €5-7 companies tier priced as a capture surface. A switching-cost bet with two unproven compounding paths. Conditional yes. The meeting is about three numbers, attach rate first.
What they claim, and what the evidence saysmarket network: Asserted only · data: Partially evidenced · marketplace: Partially evidenced
What the company asserts, held against each type's proof bar.
market network
The firm-client collaboration layer is real, which is more than a pure automation tool, but it does not compound across firms. Rated Asserted only as a network effect. The within-relationship dynamics are assessed under the 2-sided marketplace claim; the cross-firm silo finding stands.
- What looks like a market network is a per-firm collaboration workflow: each firm uses Kabilio with its own client base, siloed from other firms.
- No evidence that adding the 101st firm raises value for the first 100.
data
The strongest claim on ingredients. Kabilio processes private Spanish invoice and ledger data across firms, which is genuinely access-constrained and domain-specific. What is missing is proof that accuracy improves cross-firm with volume rather than being a fixed model plus rules. Rated Partially evidenced: the ingredients are there, the compounding loop is not yet shown.
- 97% accuracy is company-stated; the cross-firm compounding loop is asserted by structure, not shown.
- The accuracy bar is moving: Holded ships 93% OCR as an incumbent feature, so the headline gap is four points and closing.
marketplace
A claim surfaced by the pricing architecture rather than by press coverage. The accounting-firm side is the business (€129-359/mo by document volume, priced like infrastructure); the client side is priced as a capture surface (€5-7, at the floor of the market, unlimited users, free trial). Every invoice issued on the companies tier arrives pre-digitized into a firm's pipeline instead of as a PDF shoebox. That is a real 2-sided design. Rated Partially evidenced on structure alone: the discriminating number, cross-side attach rate, is not public.
- Without attach-rate evidence, the companies tier is indistinguishable from one more cheap invoicing app on a crowded floor (Holded Plus €7.50, Quipu €9.90, Billin €9.99, FacturaDirecta €0-10).
- The structure is deliberate and citable (throughput pricing on the firm side, subsidy pricing on the client side); the dynamics are entirely unproven.
Is the network effect real? Seven tests5 Partial · 2 Weak
| Diagnostic | Rating | Barrier test | What would change this |
|---|---|---|---|
| Atomic network unit | A deepened unit raises the cost of displacing Kabilio inside one firm. It does not yet wall off other firms, so no cross-firm barrier exists. | Cross-side attach data (companies-tier users linking to firms), plus any shared layer across firms: benchmarking, a vendor graph, client portability. | |
| Cold-start status | Early adoption compounds into references and data, not yet into a network others must overcome. | Evidence that firm density in a region or segment raises value for other firms there, or attach-rate data showing the subsidy converts. | |
| Density and clustering | Density matters only if it compounds; today it does not visibly. | A data or benchmarking effect that gets better the more firms in one market use it. | |
| Multi-tenanting exposure | The integration surface is the thing that discourages multi-tenanting; it is real but unproven at retention level. | Retention data showing firms consolidate onto Kabilio rather than keep it alongside incumbents. | |
| Disintermediation risk | The compliance badge no longer differentiates anyone. What remains differential is firm workflow depth, 99% bank coverage, throughput pricing, and the two-sided capture wedge incumbents lack: a3 and Sage own the accounting firm but sell no cheap client-side capture product. | Win/loss data against a3 and Sage's firm suites; an incumbent shipping a client-side capture tier would cut the wedge directly. | |
| Value curve | Compounding holds only if accuracy improves with cumulative cross-firm volume, or attach converts the subsidy tier into cross-side pull. | Accuracy rising with data volume across firms, or a rising cross-side attach rate. | |
| Switching-cost decomposition | Passes the barrier test if ripping Kabilio out means rebuilding bank connections, compliance, and client history; plausible but unproven. | Net revenue retention above 100% and firms moving all clients onto Kabilio. |
Does the moat survive AI?2 strengthens · 3 intact-but-thinner
Each moat component against LLM-era commoditisation. Every call carries its falsifier.
| Component | Outcome | Flips if… |
|---|---|---|
| Generic invoice OCR and classification | low confidence | This flips to dissolves if firm win/loss shows firms treating extraction accuracy as interchangeable across vendors. |
| Spanish regulatory compliance (Verifactu) and bank-integration depth | medium confidence | This flips to dissolves if bank connectivity and workflow-grade compliance become a purchasable layer (aggregator APIs plus certified modules) any vendor can assemble. |
| Proprietary Spanish invoice and ledger dataset compounding classification across firms | low confidence | This flips to dissolves if the classification turns out to be generic OCR that public models match, with no cross-firm learning. |
| Embedded firm workflow and switching costs | medium confidence | This flips to intact if net retention proves high and integrations prove deep enough that switching is a multi-quarter project. |
| Two-sided capture wedge (€5-7 companies tier feeding pre-digitized documents into the accounting firm's pipeline) | low confidence | This flips to dissolves if cross-side attach stays low (companies-tier users unlinked to any Kabilio firm after 90 days), leaving a cheap invoicing app competing on price against free tiers. |
What to ask the founder, and what is missing3 questions · 5 gaps
Three questions for the founder
- Of your companies-tier signups, what share are linked to an accounting firm on Kabilio within 90 days, and how many firms have onboarded their full client book onto the tier? Those two numbers separate a two-sided platform from a cheap invoicing app plus a firm tool.
- Does invoice and ledger data from one firm measurably improve classification accuracy for others, or is each firm's model independent? Show me the mechanism and the accuracy-over-volume curve.
- Sage Copilot is live, Holded ships 93% OCR, and Verifactu compliance is table stakes in every product sold since July 2025. When a3 or Sage bundle equivalent AI into the suite a firm already pays for, what specifically keeps that firm on Kabilio, and what does your win/loss against them show today?
Evidence missing
- Cross-side attach rate: what share of companies-tier signups are linked to an accounting firm on Kabilio within 90 days. This is the single number separating a two-sided platform from one more cheap invoicing app. The €5-7 tier only makes strategic sense if it attaches.
- Evidence that classification accuracy improves with cross-firm data volume. This is the difference between a real, strengthening data moat and a fixed model plus rules. It remains the decisive long-term question.
- Net revenue retention and share-of-clients penetration within the ~100 firms. Switching costs are the best barrier candidate, and only retention plus penetration data show whether they are real.
- Win/loss data against incumbent firm suites (a3, Sage) now that they ship AI. Incumbent AI shipping is no longer hypothetical (Sage Copilot live, Holded 93% OCR); what is unknown is whether firms treat Kabilio's depth as differential when the suite they already pay for adds a similar feature.
- Disclosed revenue and valuation (figures circulating publicly are estimates, not company-disclosed). Unit economics and ACV determine whether a fragmented, low-price Spanish market can support a venture outcome.
What must be true by Series A5 conditions, each with proof and kill
Derived from evidenced types only.
The proprietary Spanish data compounds into a classification advantage rather than staying a fixed model plus rules.
Proof: Classification accuracy improving with cumulative cross-firm volume, and engagement cohorts improving vertically: newer firms onboarding to higher accuracy than earlier ones reached.
Kill: Accuracy is generic and plateaus, matchable by horizontal document-AI.
The companies tier converts into cross-side attach rather than standalone cheap invoicing.
Proof: A rising share of companies-tier signups linked to an accounting firm on Kabilio within 90 days, and firms actively onboarding their client books onto the tier.
Kill: Attach stays low and the tier competes head-on with Holded Plus, Quipu and Billin on price, against free tiers, with no pull from the firm side.
Switching costs implied by the integration surface are real, not pre-seed optimism.
Proof: Net revenue retention above 100% with rising share of clients per firm (the share-of-wallet read), and CAC payback shortening as longer lifetimes lift LTV:CAC.
Kill: Firms keep Kabilio alongside incumbents on a slice of clients and churn without expansion.
Firm workflow depth holds against incumbent suites that already own the channel and ship AI.
Proof: Wins against a3 and Sage's firm suites with pricing power intact rather than discounting to close, while staying ahead on bank coverage and real-time workflow sync through the 2027 enforcement dates.
Kill: An incumbent bundles equivalent firm-grade AI into the suite firms already pay for, and firms default to it.
The Spain-specificity that protects the moat does not permanently cap the market.
Proof: Acquisition staying efficient, with rising organic and referred share among firms, extending into a second regulated geography without rebuilding the whole compliance stack.
Kill: The moat is non-portable and the company caps out at a fragmented, low-ACV Spanish market.
What would kill the thesis4 ways this dies
- The thesis breaks if the companies tier fails to attach to the accounting-firm side, since at €5-7 it cannot win standalone in a market with Holded Plus at €7.50 and free tiers below it.
- The thesis breaks if incumbent firm suites bundle equivalent Spanish-compliant AI and firms default to the vendor they already pay, now that compliance is table stakes and Sage/Holded ship AI natively.
- The thesis breaks if the classification accuracy is generic document-AI that horizontal models match, removing the data barrier.
- The thesis breaks if the Spanish regulatory specificity that defends the moat also makes it non-portable, capping the company in a fragmented low-ACV market.

{ "verdict": null }
Conditional yes, with precise conditions. The compliance badge defends nobody: Verifactu compatibility is table stakes, every incumbent has it, and Sage and Holded already ship AI. What carries the case is the pricing architecture: a €5-7 client tier priced at the floor of the market only makes sense as a capture surface for the accounting-firm side, and if clients arriving there attach to firms on the platform, Kabilio is a two-sided business whose document flow compounds. So the meeting is about three numbers: cross-side attach within 90 days, net revenue retention, and the accuracy-over-volume curve. Attach is the one I would ask for first; it is the cheapest to disclose and the hardest to fake.
