Butter (Button Underwriter) Better underwriting. Cheaper acquisition. Tighter securitization. One AI agent across all three. See how →

An underwriter
that reads every page.

Butter watches the Encompass e-folder, applies your guidelines literally, and writes a hyperlinked pre-approval back into the loan file before your UW opens it. Built so your senior UWs do more with less, your CAC drops, and your securitization files arrive cap-markets-ready at underwriting time. If v0.1 doesn't ship in your sandbox in two weeks, Phase 0 is free.

10 days
Phase 0 prove-out · $10K · refunded if it fails

Phase 1 deep build · $100K (vs $250K standard)

Phase 2B steady-state · 100/mo minimum

Your HELOC pre-underwriter · trained on your guidelines
What Ryan, Kim, Firas get from Butter:
You open the loan, decision-ready. The pre-approval is already in the e-folder, every value hyperlinked to its source.
You cite §X.Y in seconds. Every income figure, CLTV, and DTI traces back to the rule that produced it. Hildene-ready audit.
You stop sorting PDFs. Doc triage runs before you log in. Missing files flagged with the cite that called for them.
02What you get

Three places Butter compounds for Button.

Three swimlanes. Each one starts with a doc landing in your e-folder and ends with a number you can hand to a board.

01 · Underwriting

Better underwriting.

Document

Every PDF classified, every gap flagged with §-cite.

Decide

§4-2-6 income, §4-3-7 CLTV, §4-5 AVM applied verbatim.

Deliver

Pre-approval lands in Encompass before the UW opens the loan.

You get

Senior UWs stop sorting PDFs. They open files decision-ready.

02 · Acquisition

Cheaper acquisition.

Reach

Fat-finger reconnect on SSN, DOB, income typos before deny.

Recover

CMO sees which lead segments actually clear UW.

Reallocate

Rates drop, dormant pipeline rescored and surfaced.

You get

Marketing spend lands on loans that close. CAC compresses.

03 · Securitization

Tighter securitization.

Trace

Every value hyperlinks to its source PDF + §-cite.

Stratify

One rule, every loan. Documentation variance closes at UW time.

Securitize

Audit packet ships with the loan, not after.

You get

AAA expected-loss line compresses. Bps your investors keep.

How all these improve securitization bps spreads
Why
Rating agencies price documentation variance into AAA expected loss. Three underwriters reading one 401K co-borrower file three different ways = three different bps outcomes.
How
Butter applies §4-2-6 / §4-3-7 / §4-5-1 verbatim, every time. The rating-agency analyst opens the file, traces the number, finds the rule. No interpretation step.
What
Cleaner stratification at the pool layer. Tighter AAA line. Bps your investors keep.

One agent. Three lanes.
Each compounds into the next.
1 → 2. Better UW drives better CAC.
2 → 3. Better CAC feeds tighter securitization.

03 · bHow Butter integrates with Encompass

Sits inside your stack. Writes to your e-folder. Three integration options.

Butter is not a new tab, not a new tool, not a new training program for your UWs. Butter is a thin agentic layer over the Encompass tenant you already run. It watches the e-folder, runs a pre-approval pass, and writes the answer back. Your underwriter opens the loan and the work is already there.

Where Butter lives in your e-folder.

Two new attachments per loan, written by Butter, named consistently, hyperlinked to source.

Three integration options.

Tom validates the path in Free Week 0 before any $10K commitment. If none work for your IT setup, we re-scope and you owe nothing.

Option A · Preferred

Encompass REST + Document API

Service account in your tenant. Document API v3 for reads, Attachment API for write-back. Standard ICE pattern. Production-ready Day 1.

Native Encompass surface · cleanest auth · scales with volume
Option B · Fallback

Encompass SDK (.NET)

Same data surface, different pipe. Battle-tested. Slower to build than REST. Falls back here if your tenant's REST endpoints are scoped down.

= Identical functionality · longer build · works on legacy tenants
Option C · Last resort

TPO Connect, browser-driven

Functional v1 prove-out only. Used if A and B are both blocked. We re-scope before Phase 0 starts if this is the path.

= Browser automation · v1 only · re-scope required
03 · cThe engine

The whole policy. One tree. Zero black boxes.

Every rule in your guidelines compiles to a node in this tree. 8 phases. 50+ rule families. 298 §-cited decision points. Click any node to see the doc text, the formula applied, and the edge cases. The three places where the doc and verbal disagree are flagged inside the tree and surfaced again in Section 05 below.

Source: Button HELOC UW Guidelines v6.11 · Tom + Claude · Apr 28

If you want to inspect the engine before signing, this is the source of truth. Run your team's read against the tree. Every disagreement becomes a Phase 1 Week 1 alignment with Ryan / Kim / Firas.

04Open questions

Three places where the doc reads one way and earlier conversations pointed another.

We read your guidelines literally before drafting any code. Three places came up where the doc and earlier conversations gave different answers. None are blockers. We flagged them because the prior three vendors didn't, and that's the trust gate. Butter follows the doc until you tell us otherwise. Phase 1 Week 1 is where Sid + Tom sit with Ryan, Kim, and Firas to align the overlay logic that lives in their judgment but not in §X.Y, and codify it into the production engine.

Trust gate
1

401K attribution: doc and verbal disagree

You said (Nashville, Apr 8)

"20% of 401K value, ÷ 12 → monthly income."

§4-2-6-13b says

Asset depletion: (eligible liquid assets − closing costs − reserves − 10% penalty if applicable) ÷ loan term in months.

The two paths produce materially different numbers

For Linda's $300K 401K, the verbal framing yields $5,000/mo; the PDF formula yields $736/mo. Demo math above runs the PDF formula as written ($736/mo, traceable line by line). Phase 1 Week 1 codifies any in-practice overlay with Ryan / Kim / Firas as a written §4-2-6-13b addendum that becomes citable in TPR review and Hildene/Goldman securitization memos.

Butter follows §4-2-6-13b in every demo above. Phase 1 Week 1: align with Ryan / Kim / Firas on whether the verbal 20%-÷-12 rule is overlay practice or supersedes the doc, then codify the live rule into the production engine.
2

AVM count: single, or routed by amount?

You said (Apr 27 call)

"Single AVM. No double-checking. No second AVM pull."

§4-5-1 says

Two AVMs required for $250K–$400K loans (one with FSD ≤ 0.10, or two with FSD ≤ 0.20). Single AVM path for ≤$250K.

Butter routes by loan amount today. Phase 1 Week 1: align with Ryan / Kim / Firas on whether single-AVM-for-all overrides §4-5-1, or §4-5-1 controls. Sample loans 1, 3, 4 take single-AVM path; sample 2 takes double.
3

Avg credit utilization: snapshot or weighted?

You said (Nashville)

"Average credit utilization weighted by payment history, not snapshot bureau pull."

§4-2-4-16 doesn't specify

Section requires "documented utilization analysis" but does not name the calculation method. Implementation is operationally inferred from underwriter practice.

Butter uses payment-history-weighted (what your team does today). Phase 1 Week 1: confirm the method with Ryan / Kim / Firas so the rule is explicit for the next vendor and the next audit.

Phase 1 Week 1 closes all three before production code touches your e-folder.

📌 PATH 4: TINMAN

If you'd rather redeploy Tinman, Nik can introduce you to Vishal Garg @ Better. Note: Better could be a potential competitor, so tread carefully.

Phase 0 + Phase 1 = $110K total, ~3.5 months to production. You keep the code. You run it in your tenant. You hand the audit packet to the analyst Hildene puts on your next deal.

06The roadmap

Phase 0 → Phase 3+. One agent, one ladder, every step optional.

Early bird only.
Phase 0: $10K or $0 if we fail in 10 days.
Phase 1: $100K (60% discount on $250K, 100x.inc/pricing)
Phase 2: Pick your support model (2A DIY or 2B $100/close)

Where Butter expands

Once Butter sits in your stack · scoped per engagement

Five expansion paths. Pick zero, one, or all five. Each is a separate Phase 3+ engagement.

💰

3a · Finance

P&L view per loan for the CFO. Real-time margin, attribution, channel-partner economics.

📞

3b · Point of sale

Borrower feedback agent (chat / voice / email / social AI). Closes file gaps before deny.

📈

3c · Marketing

CMO feedback engine. Which lead segments clear UW, where to reallocate spend.

📊

3d · Securitization

Head-of-Cap-Markets feedback engine. Pre-deal pool review, Hildene/Goldman analyst handoff.

🔁

3e · Multi-product

Scale Butter to DSCR, Bank Statement, HELOAN, Closed-End Second.

Phase 0 starts the day mNDA + Encompass auth land. The $10K clock doesn't start until both. Each phase is an option, not a commitment. You decide whether to step up.

08Compliance

Compliance is the cost of working with cap-markets clients. Cleared so procurement doesn't slow you down.

SOC 2, GDPR, CCPA, TCPA, FINRA all cleared on our end (same as SEI).

🛡
SOC 2 Type II
Annual third-party audit. Same standard as SEI.
🌐
GDPR + CCPA
EU + California consumer privacy compliance.
📞
TCPA-safe
Consent and outreach guardrails. Phase 2 voice paths inherit.
FINRA-aligned
Recordkeeping + audit-trail patterns built in.

Data residency

All Button PII processed inside a Button-dedicated workspace. Inference runs against an enterprise LLM contract that does not retain customer data for training. Standard SOC 2 Type II controls (logging, encryption at rest + in transit, access reviews). Pen test report and SOC 2 letter available on request before contract.

Vendor lock-in protection

All artifacts produced during Phase 0 + Phase 1 (pre-approval files, classification training data, decision-logic specs, integration code) become Button property at end of engagement. If 100x can't continue, Button keeps Butter's logic and routes the operational layer to a successor. This is in the SOW, not just a promise.

Integration architecture moved to Section 04·b — three integration options (REST API · SDK · TPO Connect) live there with the stack diagram.

09The close

Test before you invest.

$10K. Ten days. Working Button inside your Encompass sandbox. Anything we get wrong by Day 10, you walk and pay $0.

Every quarter the documentation tax stays in your files, your CAC compounds, your UWs grind, and your securitization pool ships with avoidable variance. Phase 0 is ten days to find out if that gap closes.

Goes straight to Nik. No CRM, no auto-reply.
