About this appAI proposal
Dialcheck Ledger checks phone numbers in customer lists and tells you which are valid, which are reachable and which to drop before a campaign or call. Upload a file, paste numbers, or let it re-check a connected list on a schedule.
It is built for marketing agencies, small software teams and CRM admins who clean contact data for several clients or lists. Each run produces a plain report you can send on: how many numbers were bad, why, and how many credits it used.
What is different: a monthly plan with unused checks rolling over for a month instead of expiring bundles, and every run showing its cost beside the sends it avoided. Setup with common automation tools takes minutes, not a developer.

- Why this name
- Dial points to calling, check to validation, and Ledger to the cost record shown for every run.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Bulk and single checks
Upload a CSV, paste a list or check one number. Each result is valid, invalid, risky or unknown, with a reason.
No member yet
Format fixing
Normalises numbers to international format using the country set per list, so local entries are not wrongly rejected.
No member yet
Line type and region
Shows mobile, landline or VoIP and the country, so texts and calls go to the right numbers.
No member yet
Scheduled list watch
Re-check a connected list weekly or monthly and flag numbers that went bad since the last run.

How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Agencies send run report links to clients. Each report shows the product name and a link to run a free check on their own list.
- Do they become customers?
- Report readers are often the list owners and could become customers, but they may only view the report. Test how many click through and start a trial.
- First customers
- Small marketing agencies of 2 to 15 people that run SMS or call campaigns for local-service clients and manage client lists in HubSpot or Go High Level.
- Where to reach them
- Agency communities: Offer free list audits in Go High Level and HubSpot user groups, and share the report as the sample.
- Automation template galleries: Publish ready Zapier and Make templates for validating new leads, with a link back.
- Direct outreach: Message agency owners with a free sample audit of a small list of their own.
- First milestone
- Ten agencies on a paid plan within 60 days, with at least half running a second list in the month after.

RisksAI inference
- DataAccuracy depends on upstream lookup data. If it is no better than existing platforms, there is no reason to switch.
- CommercialPer-check data costs may squeeze margins on flat monthly plans and rollover. Test cost per check before fixing prices.
- RegulatoryPhone numbers are personal data. Uploads need clear retention limits, deletion and a data processing agreement.
- PlatformAutomation tool listings and CRM integrations depend on partner review and API changes.
- CommercialBuyers may see validation as a commodity and choose the cheapest credits. Reports and rollover must prove value.
