Definite
AI agents that turn weeks of bank regulatory filings into auditor-ready receipts.
On the record
Checkpoint: Window closes if Fiserv, FIS, or Workiva announces a regulator-ready reporting agent before Definite gets examiner sign-off on receipts through a live quarterly exam
The call
Definite has a real filing pain and an unbuilt trust layer to fix it, racing core-banking vendors who already ship AI agents into the same banks.
Definite built software that uses AI to help banks fill out regulatory forms that normally take weeks, and then checks the work so auditors will accept it. The problem is that the three giants who already run banks' computer systems, Fiserv, FIS, and Jack Henry, are not sitting still: Fiserv already has its own AI agents and a deal with OpenAI to do similar work, and plans to ship competing features by early 2026. Definite has no customers or proof yet that banks trust its verification system, so it is racing against the clock. The one thing that could save Definite is if it becomes the go-to choice for smaller banks and credit unions that Fiserv does not prioritize, instead of trying to sell to every bank.
Why
01
AI pressure: None apparent. Frontier models like GPT-5 can draft filings but can't verify them; Definite's recomputation layer feeds off models rather than getting replaced by them. Could AI do the core job? Only partly.
02
Bigger players: Fiserv (agentOS platform, OpenAI partnership). Fiserv already runs AI agents for AML and deposit work inside agentOS and could extend that to Call Report automation before Definite lands examiner-tested customers. Could a giant copy it? Yes, easily.
03
What protects it. A versioned rulebook plus tamper-evident receipts aimed at examiners, if Definite locks in community banks and credit unions Fiserv treats as low priority.
What would change this call
Fiserv's agentOS roadmap adds a 'reporting verification' or Call Report automation feature within 12-18 months. Shows the core-banking incumbent can close the gap before Definite gains examiner-validated traction.
Definite announces 2-3 named community bank or credit union design partners completing a live quarterly exam cycle. Shows the regulatory trust layer moat is being validated by real examiners, not just claimed.
Definite publicly commits to a sub-$10B asset community bank/credit union niche versus pursuing any-size banks. Shows a deliberate strategy to stay in segments Fiserv is less likely to prioritize.

Key numbers
- 3-person team, YC S26 batch
- No disclosed revenue or named bank customers yet
- Fiserv's agentOS already runs AI agents for AML/deposits
Named risks
- Pre-revenue with zero named customers weeks after July 2026 launch.
- Core-banking incumbents (Fiserv, FIS) already shipping AI agents that could add comparable verification features within 12-18 months.
- Brand confusion with unrelated, better-funded definite.app (Luabase Inc.) still publishing content through June 2026.
- Regulatory rulebook volatility (UK PRA reforming reporting templates, Jan 2026) could shift the addressable market the product is built around.
- Possible founder/entity data overlap with another YC S26 company, Bylaw, creating unresolved identity confusion.

Questions people ask
- Is Definite profitable in 2026?
- No. Definite is pre-revenue as of July 2026, a 3-person YC S26 team that just launched publicly on July 15, 2026 and is still soliciting bank design partners rather than reporting any signed customers or revenue.
- Could AI replace the work Definite is trying to automate?
- Yes, that is the pitch. Definite's AI agents plus a rulebook-based verification engine aim to turn weeks of manual bank regulatory filing work into hours, though this is a vendor claim unverified by any bank examiner as of July 2026.
- Who is Definite's biggest competitive threat?
- Fiserv, which already shipped agentOS with AI agents for AML and deposit intelligence and formed a strategic partnership with OpenAI in 2026, giving it agentic AI features overlapping Definite's pitch without Definite's traction.
- Who owns Definite?
- Definite is a private company backed by Y Combinator (Summer 2026 batch), founded by Gurshabd Singh Varaich, Mazin Al-Ani, and Farhan Rehman, with no other disclosed investors or ownership stake as of July 2026.
- Does Definite have any paying customers?
- No named customers were disclosed as of July 2026. Definite's own YC launch post explicitly asks readers for introductions to a VP of Finance or Engineering at a partner bank, indicating it is still seeking design partners.
- Is Definite the same company as definite.app?
- No. Definite (usedefinite.com, YC S26, bank regulatory reporting) is unrelated to definite.app, legally Luabase Inc., a Wilmington Delaware data platform founded 2023 that raised a $10M seed round in August 2025.
