What happened
Cities Today reported on 19 October 2026 that Suisun City, with about 100 employees serving 30,000 residents, introduced Polimorphic's AI telephone and web assistant 'Susie' in September 2025 and a dedicated finance hotline in December 2025 for utility-billing calls, which a third-party provider handles. The finance line receives about 1,500 calls a month and resolves about 70% without staff intervention, where 'resolved' means the call did not end in a transfer to a person. Updated vendor figures show 11,659 calls since launch and an estimated 415.3 staff hours saved. The article states these are estimated staff time, not confirmed spending reductions, and measure calls handled without staff, not completed transactions. Susie uses only the city and police websites, is not connected to the Tyler Technologies billing system, and the city has no formal AI policy; the vendor reviews call logs monthly with the City Manager's Office, which has exposed gaps in published web content.
Why it matters
Rare small-city outcome data on an AI phone line, with the article itself flagging the metric definitions, which helps buyers set realistic success measures and spot the governance gap of operating without an AI policy.
Evidence and measured results
Full Cities Today article opened. Figures are attributed to Polimorphic's demand-generation specialist; no city-published dashboard or audit was found.
Limitations and uncertainty
Vendor-supplied numbers in a vendor-sourced feature; resolution metric is lenient; savings are notional capacity, not cash.
Put this evidence to work
Lighthouse Advisory interpretation, grounded in this source. Enriched 2026-10-19; this does not change the original publication date. Each role follows the same checklist so takeaways compare across sources.
Sales
Role takeaway
- Customer problem
- A small staff spends time redirecting routine utility-billing and service calls.
- Stakeholders
- City Manager's Office
- Finance department
- Police department web owners
- Vendor (Polimorphic)
- Billing provider (Tyler Technologies)
- Discovery questions
- How is a 'resolved' call defined and audited?
- What share of calls are really for a third-party provider?
- Does the city have an AI policy?
- Which workflows would need record access next?
- Value hypothesis
- An AI phone line could absorb many direction-only calls; reported savings are estimated capacity, not cash.
- Potential engagement
- Phone-line pilot with written metric definitions and an independent monthly call sample.
- Unsupported claims
- Budget or headcount savings
- Completed transactions
- Answer accuracy
Pre-sales engineering
Role takeaway
- Fit
- Direction and FAQ calls where no account access is needed.
- Architecture and integration
- Voice/web assistant over public city and police websites; analytics; no billing-system connector today.
- Prerequisites
- Accurate public web content
- Call-routing configuration
- Interaction logging
- Constraints
- No integration with Tyler billing
- Workflow phase needs internal-record access
- No city AI policy
- Security
- Keep the assistant off internal records until access controls, logging and a policy exist.
- Proof of value
- Sample calls for correct direction, not just non-transfer
- Track repeat callers within seven days
- Compare staff call minutes before and after
Delivery
Role takeaway
- Work
- Configure assistant, route finance calls, run monthly log reviews, feed gaps into web updates.
- Dependencies
- Vendor customer success team
- City Manager's Office reviewer
- Website content owners
- Ownership
- City Manager's Office (Michael Elm named as review contact).
- Skills and adoption
- Staff read call analytics and turn recurring questions into page fixes.
- Governance checkpoints
- Adopt an AI use policy
- Define metrics before scaling
- Data-access review before workflow automation
- Acceptance criteria
- Proposed: audited correct-direction rate of at least 85% on sampled calls
- Proposed: repeat-call rate tracked and below baseline
- Proposed: policy adopted before any record access
- Risks
- Lenient success metric masks failures
- Vendor-reported outcomes only
- Governance gap as scope grows
Implementation considerations
Lighthouse Advisory interpretation across the operating dimensions a public-sector buyer must settle before this evidence becomes a design. Each note answers the question under its heading for this specific source.
Architecture and integration
What must connect, and where does the AI sit in the workflow?
Voice and web assistant grounded on public city and police web content; no integration with Tyler billing or internal records; analytics on interactions; next phase would need system integration for workflows.
Governance
Who approves, reviews and stays accountable for outcomes?
No formal city AI policy before or after deployment; controls rely on platform safeguards, scope limits and monthly log reviews.
Security and privacy
What data, permissions and controls need testing?
Limited data exposure because no account or internal-record access; future workflow phase would add record access and new controls.
Accessibility and workforce
Who is affected, and what skills or accommodations follow?
Fewer phone interruptions for a small finance team; no staffing cuts described.
Procurement
What should contracts, pricing and exit terms secure?
Vendor deployment configured in about an hour per the vendor; contract and cost not disclosed.
Operating model
Which teams own the service once it runs?
Monthly log reviews turn repeated questions into website fixes; the city is considering AI for application workflows next.
