AI MVPs for finance. Built around the audit surface investors and regulators actually inspect.

Downshift ships production-grade AI products for fintech, regtech, wealth, and embedded finance, with SOC 2-aligned controls, immutable audit logs, and the data integrity that survives a real diligence call.

Section 01

The finance engineering wall

Finance founders demo well and lose at diligence. The product works in a screencast. The audit log is missing or unreliable. PII handling is ad hoc. The data model cannot answer the regulator's basic questions: who saw what, when, and why. Every gap becomes a memo from the investor's lawyer.

The fix is to build the audit surface alongside the product, not after it. Immutable logs, append-only event streams, role-based access, idempotent transactions, reconciliations that match the source of truth. None of this is glamorous; all of it is what makes a fintech fundable.

Section 02

What we build for finance founders

Specific product types Downshift has shipped or is set up to ship in finance.

Fintech consumer apps

Banking, lending, savings, investing, and remittance products. Built on a transaction model that reconciles to the cent and an audit log that survives external review.

Regtech and compliance

KYC, KYB, AML, sanctions screening, and reporting tooling. Workflows where every decision is logged with the evidence behind it.

Wealth and advisor tools

Advisor dashboards, client portals, planning calculators, and AI-assisted research. Suitability and disclosures are first-class concerns, not bolted on.

Embedded finance

Cards, accounts, payouts, and financing inside vertical SaaS products. We build on top of regulated providers (Stripe, Unit, Plaid, Marqeta) without hiding their constraints.

AI for financial workflows

Document parsing, statement extraction, fraud and anomaly signals, and assistive tooling for analysts. AI as a productivity surface for humans, not an autonomous decisioning layer for money.

Data integrations

Plaid, Stripe, banking-as-a-service partners, custodians, and accounting systems. The plumbing that turns a finance product from prototype into a real ledger.

Section 03

Immutable audit logs covering every PII read, money movement, and configuration change
Role-based access, MFA, and reviewable access trails
Idempotent payment paths, reconciliation jobs, and ledger-style transaction modeling
Encryption in transit and at rest, secrets management, and key rotation

Finance questions

Is Downshift SOC 2 compliant?

Downshift builds products that are SOC 2-aligned by architecture, not products that have a SOC 2 certificate hanging on the wall on day one. The certification is a process the founder owns once the product is in market; Downshift hands over the architecture, controls, and documentation that make that process tractable.

Do you handle KYC, AML, or fraud?

Yes. We integrate with Persona, Alloy, Sardine, Footprint, Unit21, and similar vendors. The decision is which provider fits the founder's stack and risk profile; the integration, the workflow, and the audit log are what Downshift delivers.

What about money movement?

Downshift builds on regulated providers (Stripe, Unit, Modern Treasury, Plaid, Marqeta, Lithic). The product becomes an interface and a ledger on top of their rails, not a chartered institution itself. This is the cheapest, fastest path from idea to live-money product for most fintech MVPs.

Can you handle our investor diligence pack?

Yes. The architecture, audit log design, vendor agreements, and access controls are documented as part of the build. Founders walk into diligence with a security and integrity story that holds up, not a 'we will fix it after the round closes' promise.
