Gain vs Pactio (2026)
The first hour of a deal and its last, on one page. Gain works the first: a researcher verified graph of every company above ten employees, half a million deals and eleven thousand advisers, with market maps, watchlists and an acquisition receptivity model telling a sponsor which businesses exist, which are reachable and which might sell, consumed through relationship system sync, a spreadsheet add in, bulk feeds and pipes into a firm's own language models. Pactio works the last: sources and uses, capitalisation tables, expenses and wiring schedules synchronised so the four artefacts that must reconcile at completion actually do, errors caught before they propagate, inside the Office suite and recorded in an audit ready deal log with controlled access. The evidence types differ as much as the products. Gain publishes who uses it, four of the largest global buyout firms, three prominent independent investment banks, every leading strategy consultancy and all four major accounting groups. Pactio publishes who believes in it, fourteen million led by the venture arm of one of the world's largest private equity firms, digital bank founders among the angels, a global professional services alliance, and no named customer. One record shows usage and the other endorsement, which are different stages of the same proof. The risk surfaces could not be less alike and share one property, that the subject cannot see the system. Gain's subject is the scored company, assessed for openness to acquisition on public signals it cannot correct, in a graph its potential buyers read. Pactio's subject is the limited partner, whose identity and subscription records persist in a platform aggregating deal structures across sponsors who compete for the same assets and the same capital, under boundaries nobody has published. And each holds material whose protection is asserted rather than attested, competing bidders' notes on shared profiles at one, the schedules that direct deal proceeds at the other.
- Sourcing is the job. A researcher verified graph of every company above ten employees, market mapping, watchlists and acquisition receptivity prediction, with usage named at the very top of the market.
- The data arrives where you work. Two way relationship system sync, a spreadsheet add in, bulk exports, interfaces and structured feeds into your own language models.
- One system replaces the point solutions. Sourcing through research, diligence support and portfolio tracking on a single graph.
- Completion is the failure you cannot afford. Four artefacts synchronised so they reconcile at close, errors caught before they propagate, an audit ready deal log, all inside the Office suite.
- The believers are named even where customers are not. A fourteen million round led by a major private equity firm's venture arm, digital bank founders as angels, and a global professional services alliance for deal execution.
- The lifecycle roadmap is credible. Private credit and secondaries extensions with reusable investor data, from a team pairing a former Goldman private equity executive director with an AI researcher.

The short version of each
Gain
Gain maintains a researcher verified graph of every company above ten employees, half a million deals and eleven thousand advisers, with market maps, watchlists and an acquisition receptivity model, consumed through relationship system sync, a spreadsheet add in, bulk feeds and pipes into a firm's own language models, with a named customer list spanning four of the largest global buyout firms and all four major accounting groups. The AI FinTech Index records that named usage answers who relies on it rather than how accurate it is: no accuracy rate or outcome evaluation exists for the receptivity model, which operates near the boundary market conduct rules police, and the scored company cannot see or correct the profile its potential buyers read.

Pactio
Pactio synchronises the four artefacts that must reconcile at a deal's completion, sources and uses, capitalisation tables, expenses and wiring schedules, catching errors before they propagate, inside the Office suite with an audit ready deal log and controlled access, backed by fourteen million dollars led by the venture arm of one of the world's largest private equity firms and a global professional services alliance. The AI FinTech Index records the gap between endorsement and evidence: no named customer, no measured error prevention rate, headcount figures conflicting between sources, wiring schedules protected by adjectives rather than a located attestation, limited partner records persisting under an undefined reusable data ambition, and responsibility for a synchronisation error contractually unallocated in anything published.

Common questions
Do Gain and Pactio compete for the same buyer?
They never compete, because they work the first hour of a deal and its last. Gain tells a sponsor which businesses exist, which are reachable and which might sell, through a researcher verified graph with market maps and an acquisition receptivity model. Pactio makes the four artefacts that must reconcile at completion actually reconcile, sources and uses, capitalisation tables, expenses and wiring schedules, with errors caught before they propagate. A firm could plausibly run both without them ever touching. Graded by AI FinTech Index against the same capability axes from each vendor's own published materials, verified August 23, 2026. No vendor pays for placement.
How do the two evidence types differ?
They are different stages of the same proof. Gain publishes who uses it: four of the largest global buyout firms, three prominent independent investment banks, every leading strategy consultancy and all four major accounting groups. Pactio publishes who believes in it: fourteen million led by the venture arm of one of the world's largest private equity firms, digital bank founders among the angels, a professional services alliance, and no named customer. Usage and endorsement deserve equal scepticism applied differently. Graded by AI FinTech Index against the same capability axes from each vendor's own published materials, verified August 23, 2026. No vendor pays for placement.
What does Gain's customer list not answer?
Named usage answers who relies on it, not how accurate the graph or the receptivity model is. No accuracy rate exists, the receptivity predictions are never evaluated against actual outcomes, coverage necessarily thins outside well documented jurisdictions, and the model operates near the boundary market conduct rules police. The scored company, assessed on public signals it cannot correct in a graph its potential buyers read, has no route in. Graded by AI FinTech Index against the same capability axes from each vendor's own published materials, verified August 23, 2026. No vendor pays for placement.
What should Pactio be asked about its most sensitive data?
The wiring schedules, which direct where deal proceeds are sent, are protected in public material by adjectives rather than any located attestation, and responsibility for a synchronisation error reaching a wiring schedule is contractually unallocated in anything published. Limited partner identities and subscription records also persist under a reusable investor data ambition nobody has defined, with aggregation across competing sponsors carrying no published boundary. Graded by AI FinTech Index against the same capability axes from each vendor's own published materials, verified August 23, 2026. No vendor pays for placement.
What is unpublished at both?
Neither publishes a price or a residency position, and each system's subject cannot see it: the company scored for openness to acquisition at Gain, the limited partner whose records persist at Pactio. Pactio's headcount figures also conflict between sources, and its compliance collection names no eligibility or anti money laundering framework.

How does the AI FinTech Index grade Gain and Pactio?
Both are graded on the same fifteen capability axes from public sources, each grade traceable to its artifact. The AI FinTech Index records the pair as usage against endorsement, with each vendor holding material whose protection is asserted rather than attested, competing bidders' notes on shared profiles at one and the schedules directing deal proceeds at the other. The index publishes no composite score and declares no winner.

The two evidence types deserve equal scepticism applied differently: Gain's named usage answers who relies on it and not how accurate the graph or the receptivity model is, with no accuracy rate, no evaluation of receptivity predictions against actual outcomes, and coverage that necessarily thins outside well documented jurisdictions, while Pactio's named backing answers who diligenced the company and not whether the product works, with no named customer, no measured error prevention rate and headcount figures conflicting between sources.
Gain's shared profiles carry competing bidders' proprietary notes under a data governance vector named without published substance, its receptivity model operates near the boundary market conduct rules police, and no security artifact was located for the infrastructure holding it all.
Pactio's wiring schedules are the artefact deciding where deal proceeds are sent, protected in public material by adjectives rather than any located attestation, its limited partner records persist under a reusable investor data ambition nobody has defined, its compliance collection names no eligibility or anti money laundering framework, and responsibility for a synchronisation error reaching a wiring schedule is contractually unallocated in anything published. Neither publishes a price or a residency position, and each system's subject, the company scored for sale at one, the limited partner whose records persist at the other, has no route into it.
