73 Strings vs AlternativeSoft (2026)
Opposite ends of the ownership lifecycle. AlternativeSoft decides what an allocator buys, screening a stated five hundred thousand funds across fourteen named inbound data feeds, running the risk statistics and optimization an investment committee expects, and pre populating due diligence questionnaires from a manager's own documents with the manager's team named as the review step. 73 Strings decides what the position is worth once owned, running extraction, monitoring and valuation over one private capital data model for general partners and allocators whose assets it states at close to $10 trillion, with Eurazeo and Sofina named. The commercial disclosure runs AlternativeSoft's way, its billing basis published as module based and varying with institution size and connected feeds, so a buyer can reason about the price levers, where every route through 73 Strings ends at a demo booking. Security disclosure is weak at both, in different ways. 73 Strings references a SOC Type II attestation but buries it inside a product answer with no trust center, scope or report route, while AlternativeSoft names an international standards body without the standard and writes compliant where an audited firm writes certified. Both operate two sided data platforms and neither states the boundary, a connected client community selling comparables at one, and a single database serving managers and the allocators screening them at the other.
- Your marks land in audited statements. Discounted cash flow, comparables and benchmarking run with audit trail, version control and full lineage, with analyst overrides supported for the reasonableness testing valuation standards require.
- Your reporting cycles die in reconciliation. Extraction, monitoring and valuation share one private capital data model, so time series stay consistent across cycles rather than being rebuilt each quarter.
- Your peers already sit on the platform. Client assets are stated at close to ten trillion dollars across pension funds, sovereign wealth funds, limited partners and general partners, with Eurazeo and Sofina named as European holders.
- Your job is choosing managers, not marking them. Screening spans a stated five hundred thousand funds through fourteen named inbound feeds consolidated into one universe, with the reconciliation work done for you.
- Your procurement wants price logic before a sales call. The billing basis is published, module based and varying with institution size, module selection and connected feeds, which is more than the usual demo only pattern.
- Your questionnaire burden has a named review step. Fund documents pre populate due diligence responses which the manager's own team reviews and finalizes, and the assistant facing layer offers a local deployment option.

The short version of each
73 Strings
73 Strings runs extraction, monitoring and valuation over one private capital data model for general partners and allocators whose assets it states at close to $10 trillion, with Eurazeo and Sofina named and analyst overrides supported on the assumptions that drive each mark. According to the AI FinTech Index, its central exposure is the one its own product creates. A 73 Strings valuation feeds the net asset values that management and performance fees are computed from, and the platform openly supports overriding the discount rate and growth assumptions behind that number. Nothing states whether overrides are aggregated, compared against realized exits or disclosed to limited partners, even though realized exits make marks uniquely checkable and no back testing is published. A SOC Type II attestation reference sits buried inside a product answer, with no trust center, scope or report route, and every commercial route ends at a demo booking.

AlternativeSoft
AlternativeSoft screens a stated five hundred thousand funds across fourteen named inbound data feeds, runs the risk statistics and optimization an investment committee expects, and pre populates due diligence questionnaires from a manager's own documents with the manager's team named as the review step. According to the AI FinTech Index, its billing basis is published as module based and varying with institution size and connected feeds, so a buyer can reason about the price levers before a call. A generated questionnaire answer becomes a representation by a fund manager to institutional investors, yet no accuracy rate exists for the generation, nothing marks generated text as generated, and no disclaimer confirms the manager remains solely accountable. Its security language names an international standards body without the standard, writing compliant where an audited firm writes certified.

Common questions
Do 73 Strings and AlternativeSoft compete?
Rarely head on. AlternativeSoft serves the selection decision, screening and diligence before an allocation, and 73 Strings serves the ownership phase, valuing and monitoring what is already held, so an allocator could plausibly run both at different points of the same lifecycle. 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.
Which vendor publishes more commercial detail?
AlternativeSoft, which publishes its billing basis as module based and varying with institution size and connected feeds. 73 Strings publishes no rates, no unit of charge and no line between its software price and its valuation specialist services. 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 wrong with each vendor's security disclosure?
Different failures of the same kind. 73 Strings references a SOC Type II attestation inside a product answer with no trust center or scope, and AlternativeSoft names a standards body without a numbered standard, writing compliant where an audited firm writes certified. Neither documents its security certifications in detail. 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 data boundaries does each leave unstated?
At 73 Strings, whether benchmark and comparable data derives from client portfolios and whether contribution is optional. At AlternativeSoft, what crosses between the manager and allocator sides of the same database, and whether uploaded diligence material is used beyond the engagement it was supplied for.

The liability exposures are specific to what each product produces. A 73 Strings valuation feeds net asset values that management and performance fees are computed from, and the platform openly supports overriding the discount rate and growth assumptions driving that number. Nothing states whether overrides are aggregated, compared against realized exits or disclosed to limited partners, though realized exits make marks uniquely checkable and no back testing is published.
An AlternativeSoft questionnaire answer becomes a representation by a fund manager to institutional investors, no accuracy rate exists for the generation, nothing marks generated text as generated, and no disclaimer confirms the manager remains solely accountable. Both leave model supply chains dark, with no provider named for the components reading unpublished portfolio financials and offering memoranda.
AlternativeSoft's naming of three assistants a client may connect from describes the buyer's tools rather than its own suppliers. Both two sided data boundaries, comparables possibly derived from client portfolios at one and a shared manager and allocator database at the other, are unstated.
