Why Litmus Exists for Fintechs

There is nothing more frustrating than when you have identified your ICP, developed the messaging, launched the targeted campaigns and the market still doesn't know what you do.

Litmus was built to fix that.

With most ICPs not being much more than titles + AUMs, you need better buyer data. Litmus is grounded in patterns observed across 50+ workshops with buyers like yours plus channel behavioral modes to pick the right distribution model so your next message lands perfectly.

NEW Channel Behavioral Modes

Your buyers process the same message differently depending on where they see it. Litmus maps how each persona shifts behavior across four channels.

LinkedIn

Peer-Visibility

They share what makes them look informed. Everything else gets scrolled past.

Website

Due Diligence

Every claim gets matched against what they already know about their own institution.

Thought Leadership

Learning

Open to ideas but hostile to disguised sales. Teach them something they can use tomorrow.

Ads

Interruption

You have two seconds and the highest skepticism of any channel. Specificity is the only thing that earns a click.

Sample Litmus

Rob Castellano
CEO, Community Bank | $7.2B Assets | Fiserv Premier | Birmingham, AL

Career Narrative

Started as a commercial loan officer at 24. Turned around an underperforming market in Tuscaloosa. Joined current bank as EVP of Commercial Banking at 38, became CEO at 48. Grew the bank from $800M to $7.2B through organic growth and four acquisitions. Entire career in Alabama banking.

Education

BS Finance, University of Alabama. MBA, Vanderbilt Owen Graduate School of Management.

  • State-chartered community bank, FDIC-insured
  • $7.2B assets, 47 branches, 820 employees
  • Birmingham metro, Huntsville, Tuscaloosa, Mobile
  • 60% consumer, 30% small business, 10% commercial/CRE
  • Actively evaluating acquisitions in Mississippi and Tennessee
  • President and CEO, 10 years in role
  • Direct approval up to $2M. Board approval above $2M or multi-year over $5M.
  • Signs every technology contract over $500K
  • CIO reports to CFO, not directly to Rob (structural buffer from tech decisions)
  • Board trusts his judgment but increasingly asking about digital strategy
  • Core: Fiserv Premier (on-prem, contract renewal in 8 months)
  • Digital banking: NCR Digital Insight (aging, complaints rising)
  • Lending: Abrigo (recently upgraded from 15-year-old Access database)
  • Cloud posture: Minimal. Skeptical of cloud for banking data.
  • API readiness: Low. No API strategy. Integrations are file-based.
  • Conservative risk tolerance. Has seen two competitors fail from aggressive growth.
  • Gut-instinct decisions tempered by CFO data. Trusts people, not slide decks.
  • Evaluates vendors through peer references. Calls CEO friends before any decision over $500K.
  • Information diet: American Banker, Alabama Bankers Association, peer CEO dinners. Does not use LinkedIn.
  • Will change if inaction is riskier than action. Not motivated by excitement.

Top Challenges

  • Deposit competition: Losing younger customers to Chime and Marcus. Net new checking accounts down 12% YoY.
  • Core contract renewal: Fiserv renewal in 8 months. CFO wants to negotiate harder. Rob isn't sure he has leverage.
  • Talent: Lost best commercial lender to a fintech. IT team averages age 52.

Competitive Anxiety

A $4B competitor in Birmingham launched a slick mobile app with Alkami and is running aggressive digital marketing. Rob's board chair forwarded the competitor's Instagram ad and asked "Why don't we have this?"

  • Active trigger: Fiserv renewal + board pressure converging into first serious tech evaluation in 5 years
  • Budget: $8.5M annually (11% of non-interest expense)
  • Buying committee: CEO (final sign-off), CFO, CIO, CRO, General Counsel
  • Sales cycle: 9-15 months. Rob once took 22 months to select a treasury management vendor.
  • Dealbreakers: No Fiserv integration = dead. No peer references at similar banks = dead.

Language That Resonates

  • "We work with 40 community banks your size across the Southeast."
  • "Here is what First National in Jackson said about their experience with us."
  • "This integrates natively with Fiserv Premier. No middleware required."
  • "You will not need to hire additional staff to manage this."

Language That Repels

  • "Disrupt your legacy infrastructure."
  • "AI-powered" anything without a specific, provable use case.
  • "Move fast and break things."
  • "Our Series C funding..." (Rob doesn't care about your investors; he cares about your P&L)

Objection Patterns

  • "We already have something that does this." (Default: inertia. Show specific capability gaps with dollar impact.)
  • "What happens if your company goes under?" (Resolve with financial transparency and escrow provisions.)
  • "Let me talk to some people first." (This is a buying signal. Offer peer CEO references.)
