Best Embedded Finance / BaaSs of 2026

Increase is the pay-per-transaction Banking-as-a-Service platform for builders whose evaluation centers on no monthly minimum plus per-transaction pricing rather than custom-quoted enterprise contracts. Founded 2020 by ex-Stripe engineering, Increase built around the thesis that BaaS should price like Stripe Payments (per-transaction) rather than like enterprise SaaS (custom-quoted minimums); for low-volume builders who do not yet justify a $5K monthly retainer, Increase removes the floor.

Three tiers. Sandbox is free with API-first banking and payments and bank-of-record relationships. Production runs pay-per-transaction with no minimum on entry, including ACH, Wire, RTP, and checks. Enterprise is custom contract with dedicated tech support and SOC 2 audit; typical Enterprise customers run higher monthly volume and want a contract structure rather than per-transaction billing.

The load-bearing wedge is the no-monthly-minimum entry plus the API design from ex-Stripe engineers. Where Unit, Synctera, and Treasury Prime all carry $5K to $10K monthly minimums, Increase lets you ship a banking product before you have product-market fit; for indie builders or pre-seed startups, Increase is the cheapest way to validate a banking workflow. The catch is the per-transaction pricing scales with volume rather than flattening, and the brand recognition is narrower than Unit so procurement teams may push back.

Stripe Treasury is the Stripe-bundled BaaS for SaaS already running Stripe Connect whose evaluation does not justify standing up a second BaaS vendor. Launched 2020 by Stripe Inc., Treasury built around the thesis that platforms already on Stripe Connect should be able to add embedded accounts, cards, and treasury features without taking on a separate BaaS contract; the Goldman Sachs Bank-of-Record relationship is the regulatory perimeter and Stripe owns the bank integration.

Three tiers. Free testing covers Treasury API plus Stripe Connect with bank-of-record (Goldman Sachs and similar). Standard charges 0.5 percent basis points on Treasury balances with no platform fee. Premium support adds the upgrade tier with architectural reviews and a dedicated Stripe team.

The load-bearing wedge is the bundle inside the Stripe stack. Where Unit, Increase, and Treasury Prime sit alongside your existing payments stack, Treasury folds inside Stripe Connect so the Connect onboarding, KYC, and dashboard you already maintain extend straight into banking; for Stripe-Connect-native platforms, this eliminates a vendor relationship. The catch is the lock-in to Goldman Sachs as the single Bank-of-Record and the absence of multi-bank routing that Treasury Prime ships natively.

Column is the API-first nationally chartered direct bank for builders whose evaluation centers on eliminating the middleman entirely. Founded 2020 by ex-Plaid leadership, Column took the unusual route of acquiring an OCC-chartered national bank and rebuilding it as an API-first stack; the result is a BaaS platform where Column is the bank, not the broker, with direct access to the Fed and the payment rails.

Three tiers. Sandbox is free with API-first bank access and direct ACH plus Fed plus Wire calls. Production is custom-quoted at the entry tier with direct bank (no middleman) across lending, accounts, and payments. Enterprise is custom contract with multi-region and OCC charter visibility.

The load-bearing wedge is the OCC charter plus direct rail access. Where Unit, Synctera, and Treasury Prime broker bank-partner relationships and carry the concentration risk those partner banks expose, Column owns the bank itself; for builders worried about Synapse-style middleman collapse risk after 2024, Column moves the regulated perimeter inside the platform you contract with. The catch is the smaller team and the operational maturity gap versus more established partners.

Modern Treasury is the payments and ledger platform for finance and engineering teams whose evaluation centers on reconciliation and ledger primitives rather than full BaaS account-issuance. Founded 2018 in San Francisco, Modern Treasury built around the thesis that the load-bearing piece for high-volume payments operations is the ledger plus reconciliation layer (matching bank statements to internal records and surfacing breaks), not account-issuance.

Four tiers. Sandbox is free with payments, ledger, and reconciliation APIs. Standard is custom-quoted at the entry monthly tier with ACH plus Wire plus RTP. Pro is custom-quoted at the scale tier with multi-bank and multi-currency. Enterprise is custom contract with a dedicated solutions team and SOC 2.

The load-bearing wedge is the reconciliation focus rather than account-issuance. Where Unit, Synctera, and Column issue accounts and cards inside your product, Modern Treasury sits alongside an existing bank relationship and operates the payments orchestration layer; for fintechs and marketplaces moving large volumes that already have bank accounts, Modern Treasury solves the reconciliation problem the bank does not. The catch is it does not issue accounts or cards, so for teams who actually need account-issuance, Unit or Column fits the brief better.

Unit is the mainstream Banking-as-a-Service platform for SaaS teams whose evaluation centers on the broadest BaaS reference base plus Bank-of-Record diligence. Founded 2019 in New York, Unit built around the thesis that any SaaS should be able to offer banking, cards, and payments inside its own product without becoming a bank itself; the platform brokers the bank-partner relationship so the SaaS team owns the user experience and the bank owns the regulatory perimeter.

Four tiers. Sandbox is free with banking, cards, and payments APIs. Production Core is custom-quoted at the entry monthly minimum with bank-partner-of-record. Production Plus is custom-quoted at the scale tier with custom workflows. Enterprise is custom contract with dedicated bank partnerships and SOC 2 plus PCI.

The load-bearing wedge is the breadth of the reference base. Where Treasury Prime routes across multiple banks and Column ships a single OCC-chartered direct bank, Unit ships the SaaS-onboarding playbook most builders actually follow; if you want to launch the same product Ramp or Jasper Health did, Unit shipped the workflow. The catch is the entry monthly minimum is the highest of the cheap options here, and Bank-of-Record concentration sits on Unit-chosen partner banks rather than your own pick.

Synctera is the smart-bank network BaaS for builders whose evaluation overlaps Unit on mainstream-BaaS wedge but adds lending APIs and a smart-bank partner network. Founded 2020 by Peter Hazlehurst (ex-Uber Money), Synctera built around the thesis that BaaS should ship banking, cards, and lending in one platform with a smart-bank partner network rather than separate vendors per product line.

Four tiers. Sandbox is free with banking, cards, and lending APIs on the smart-bank network. Production Standard is custom-quoted at the entry tier with smart-bank-partner-of-record and compliance plus reporting. Pro is custom-quoted at the scale tier with multi-bank, multi-program, and lending plus cards plus accounts. Enterprise is custom contract with dedicated tech, compliance, and bank-charter advisory.

The load-bearing wedge is the lending API plus the smart-bank partner network. Where Unit, Increase, and Stripe Treasury ship banking and cards but require a separate vendor for lending, Synctera bundles lending into the same platform; for fintechs whose roadmap includes credit products beyond debit and accounts, Synctera covers both wedges in one contract. The catch is the brand recognition is narrower than Unit and the entry monthly tier carries similar minimums to Unit without Unit's reference-base depth.

Treasury Prime is the direct bank network BaaS for builders whose evaluation centers on multi-bank routing and direct bank-partner relationships rather than a single Bank-of-Record. Founded 2017 in San Francisco, Treasury Prime built around the thesis that BaaS should not centralize a single Bank-of-Record but instead route across multiple partner banks; the platform brokers the relationship to multiple banks so builders can choose which bank holds the deposits.

Two tiers. Standard is custom-quoted at the entry monthly tier with direct bank-partner network and accounts plus payments API. Enterprise is custom contract with multi-bank routing and white-label compliance tools.

The load-bearing wedge is the multi-bank routing plus the direct bank-partner relationships. Where Unit and Synctera concentrate on a small set of partner banks and Stripe Treasury locks to Goldman Sachs alone, Treasury Prime lets builders pick the bank by routing across the network; for fintechs that want to negotiate deposit pricing or diversify Bank-of-Record concentration, Treasury Prime is the only platform here that ships multi-bank routing as a first-class primitive. The catch is the entry monthly tier is the highest in this lineup and the platform is genuinely targeted at later-stage fintechs rather than greenfield SaaS adding banking.
