LeadLedger

Idea

A dispute-and-spend command center for home service contractors who buy paid leads from Angi, Thumbtack, and Google Local Services Ads. LeadLedger ingests every billed lead, flags the ones that qualify for a credit under each platform's own stated policy, auto-drafts the dispute with evidence attached, tracks each platform's submission deadline, and rolls it all up into one cost-per-booked-job view by source. HVAC, plumbing, roofing, and remodeling contractors run two or more of these platforms at once with no shared view of which one is actually paying for itself.

Market gap

Contractors routinely run Angi, Thumbtack, and Google LSA at the same time, and each platform has its own dispute mechanism, its own deadline, and its own definition of a "bad lead." None of them, and none of the marketing tools built for agencies, unify tracking and dispute filing across all three for the contractor who owns the business.

The timing is sharper than usual right now. Google eliminated its manual LSA dispute flow on July 24, 2024, replacing it with an automated credit system Google itself describes only as "more credits, on average," with no published success-rate data (bluecorona.com). Angi (which now also operates the HomeAdvisor brand under one company) settled with the Vermont Attorney General in October 2025 over deceptive "Certified Pro" marketing (ago.vermont.gov), on top of a 2023 FTC consent order requiring HomeAdvisor to pay up to $7.2 million for misrepresenting lead quality and lead-matching (ftc.gov). Thumbtack's own Trustpilot page sits at "Poor," 2.2 to 2.4 out of 5, with a recurring, specific complaint: refunds are issued only as platform credit, not cash, so a contractor stuck with a bad lead is forced to keep spending on the same platform to ever see the money again. Lead costs have roughly doubled over five to seven years while close rates have fallen, and no one platform's dashboard shows a contractor the one number that matters: which source actually turns into booked, paid work.

Total Addressable Market (TAM)

Bottom-up, anchored to the one figure with a primary source:

• Angi reports approximately 111,000 average monthly active service professionals for Q4 2025 (Angi Inc. 10-K, filed via investor relations).
• Industry comparison content (contractor-facing guides comparing HomeAdvisor/Angi, Thumbtack, Houzz, Porch, Yelp, and Bark side by side) confirms it is standard practice for a contractor to run two or more paid-lead platforms at once, not one.
• Assumption: roughly 40 percent of Angi's active pro base also buys leads from at least one other platform (Thumbtack or Google LSA), putting roughly 44,000 businesses inside Angi's own reported base into the "multi-platform, needs a unified view" segment.
• Thumbtack and Google LSA do not publish a directly comparable active-pro count (Thumbtack's public materials cite projects and dollars paid to pros, not a pro headcount), so this TAM does not add a separate Thumbtack or Google LSA base on top. As a planning range, accounting for contractors whose primary platform is Thumbtack or Google LSA rather than Angi but who are equally multi-platform, a reasonable total addressable population is 80,000 to 120,000 US home service businesses spending on 2+ paid-lead platforms.
• ACV: $79 to $149 per month (tiered by number of connected platforms and lead volume), or roughly $950 to $1,790 per year. Midpoint used below: $1,200.

TAM = 80,000 to 120,000 businesses x $1,200 = roughly $96M to $144M.

SAM: the subset visibly and actively frustrated enough to be searching for a fix, sized off complaint volume (37,000+ Trustpilot reviews for Angi Leads, thousands more for Thumbtack, 1,200+ BBB complaints against HomeAdvisor/Angi). Estimate 25 percent of TAM = 20,000 to 30,000 businesses, or roughly $24M to $36M.

SOM: a realistic year-one target for a 1 to 3 person team selling direct via SEO and content into the communities already complaining (ContractorTalk, r/HVAC, r/Plumbing, r/Electricians) plus a free lead-cost calculator: 250 to 500 paying customers x $1,200 = $300K to $600K ARR.

Monetization strategy

Flat monthly SaaS subscription, billed per business account, tiered by number of connected lead platforms and monthly lead volume. No success fee in the MVP: a flat fee keeps the pitch simple ("stop leaking money on leads you were never on the hook for") and avoids the trust problem of taking a cut of money the contractor still has to fight the platform for.

Pricing strategy

• Starter, $79/month: one connected lead platform, up to 40 leads/month tracked, dispute drafting and deadline alerts, cost-per-source dashboard.
• Growth, $149/month (anchor): up to 3 connected platforms (Angi, Thumbtack, Google LSA), unlimited leads, staff seats, priority alert channel (SMS in addition to email).
• Multi-location, custom: for contractors running more than one branded location or franchise territory, billed per connected location.

Entry point is Starter, since most contractors start by wondering whether their single worst-performing platform is worth keeping; Growth is where the cross-platform cost-per-booked-job comparison, the actual reason to buy, lives, so pricing pushes toward it.

Lead magnet

A free, no-signup "Lead Cost Calculator": a contractor pastes in what they paid for their last 20 leads from any platform and how many turned into booked jobs, and gets back their real cost-per-booked-job and close rate, benchmarked against the industry ranges reported in trade press (for example, the $300 to $475 cost-to-book-a-$1,200-job math and 15 to 22 percent HVAC close rates reported by Astra Results Marketing). The tool ends with "connect your accounts to track this automatically and catch your next bad-lead credit before the deadline."

Competitors

• Angi Leads / Angi (formerly marketed separately as HomeAdvisor, now one company): sells leads and runs its own internal, opaque dispute process with short windows and a track record, per FTC and Vermont AG findings, of overstating lead quality.
• Thumbtack: sells leads, charges automatically on delivery, and issues approved refunds only as platform credit rather than cash.
• Google Local Services Ads (LSA): sells pay-per-lead placements; replaced its manual dispute flow with an automated credit system in July 2024 with no published, independently verified success-rate data.
• WhatConverts: call-tracking and lead-scoring software sold mainly to marketing agencies managing client ad accounts; has a documented, blog-cased LSA dispute-flagging workflow, but it is agency-operated, LSA-only, and not built as a self-serve tool for a contractor to run across Angi's and Thumbtack's form-based leads.

What competitors offer now

Angi, Thumbtack, and Google LSA each offer their own single-platform dispute mechanism: submit a claim through their own portal, wait out their own window (roughly 7 to 14 days depending on platform and lead type), and receive their own decision with no visibility into why a similar-looking lead was approved on one platform and denied on another. None of the three gives a contractor a combined view of what they are spending and winning back across all of them. WhatConverts offers real lead-quality scoring and dispute-flagging, but it is built for an agency's workflow (call recording, transcription, manual scoring rules an ops person configures) and only documented for Google LSA; it does not ingest Angi's or Thumbtack's lead-notification emails or draft dispute submissions for their non-API forms.

What can be done differently to attract customers

Go direct to the contractor, not through an agency, and cover the specific platforms (Angi, Thumbtack, Google LSA) contractors are actually running side by side, not just one. Instead of asking a contractor to configure a scoring model, ship each platform's own published dispute-eligibility criteria (no-answer, wrong trade, wrong service area, duplicate, out-of-budget) as a working default, so the product is useful on day one from an email-forwarding setup, no call-tracking number or CRM migration required. The wedge is the side-by-side cost-per-booked-job report: the single number contractors say in reviews and forums they cannot get from any platform, because no platform benefits from showing it to them.
