For investors & operators
BidFast is a $29/mo tool that turns a 90-second voice note into a branded, legally compliant proposal — before a service operator leaves the job site.
Here's the market, the model, and what it takes to build it.
Top 3 reasons to fund
- ✓ 1.3M solo service operators lose jobs to bigger firms — credibility gap, not price gap
- ✓ Nobody owns AI-native proposal + pricing intelligence for soft trades (cleaning, painting, pest control)
- ✓ 88% gross margin, 8.8:1 LTV:CAC, bootstrappable at $27.5K
Top 3 risks
- ⚠ XBuild ($19M, a16z Jan 2026) expanding from roofing into soft trades — 12–18 month window
- ⚠ Pricing cold-start — crowdsourced flywheel needs onboarding calibration to work at launch
- ⚠ Compliance library costs $13.5K–$30K to build properly — legal review required for 35 states

Market Opportunity
Why now
Housecall Pro (200K+ users) shipped e-signatures in January 2025 but has no AI proposals. XBuild raised $19M from a16z in January 2026 (SiliconAngle, Jan 20 2026) for roofing estimating — validating AI proposals but ignoring soft-service operators (painting, cleaning, pest control). The window for an AI-native soft-service proposal tool is 12–18 months wide before incumbents catch up. Voice AI quality crossed commercial viability in 2024.
Solo Soft-Service Operators (Primary)
One-truck painters, cleaners, pest control, pressure washers. ~800K businesses. Deepest pain — lose $5K–15K jobs to larger competitors because proposals look amateur. Most profitable BidFast target.
Small Crew Operators (2–5 staff)
Need team-level proposal consistency across estimators. Multiple staff, different quality levels. ~500K businesses. Higher ARPU opportunity ($59–99/mo Grow/Team tier).

Voice of the customer
"I go to 3-4 estimates a day — biggest issue is sending proposals on time. I lose jobs because I'm still at home typing it up at 11pm."
— r/Contractor — 340 upvotes, 2025
"My proposals used to look like I typed them on my phone. Clients would compare them to the big company's 4-page PDF and pick them."
— r/PestControl community, 2024
"I didn't even know I needed a 3-day right of rescission notice in California. Almost got sued once."

Competitive Landscape
XBuild (x.build)
AI construction estimating — roofing proposals
Well-funded, site photo analysis, measurement report import (EagleView, Hover, GAF)
Hard construction only (roofing, general construction). No soft-service. No voice-to-scope. No compliance layer. 12–18mo to expand to soft trades per roadmap.
Price source: x.build (no public pricing), SiliconAngle Jan 2026
Proposify
Template-driven proposal software for sales teams
Polished product, good integrations, established brand
No AI scope writing. No voice. No trade pricing. No compliance. Built for sales teams, not field service operators.
Price source: support.proposify.com/hc/en-us/articles/37747171357979-Subscription-plans-and-pricing, 2026
Jobber
Field service management (scheduling, invoicing, quoting)
200K+ users, strong brand in trades, e-signature, app ecosystem
Voice quotes but no AI scope writing. No pricing intelligence. No compliance layer. Priced for growing businesses, not solos.

Product & Technology
Product overview
BidFast is a mobile-first SaaS tool for solo and small-team soft-service operators who lose jobs to larger competitors because their proposals look amateur. Operators talk about a job for 90 seconds, and BidFast generates a branded, line-item proposal with local pricing calibration and the correct state-specific legal disclosures, ready for e-signature on the spot. Plans start at $29/month.
How it works technically
Voice → Whisper transcription (audio deleted post-transcription) → GPT-4o scope extraction with trade-specific prompts → pricing calibration against local market flywheel data → 35-state compliance template injection → branded PDF generation → delivery + e-signature via Hellosign API. AI cost per proposal: $0.52–$1.57 at current API rates (ESTIMATE — derived from GPT-4o token costs + Whisper pricing, March 2026).
Hardest problem to solve
Pricing cold-start: BidFast needs local pricing data to calibrate proposals, but has no data at launch. Solution: mandatory 3–5 question onboarding calibration (trade type, zip code, 3 recent job prices) builds a minimum viable model instantly. Crowdsourced flywheel activates at scale (100+ operators in a metro). RS Means licensing ($15K+/yr) is too expensive for MVP — onboarding calibration is the viable path.
Tech stack decisions
| Layer | Chosen | Rejected | Reason |
|---|---|---|---|
| Voice transcription | OpenAI Whisper | Rev.ai, AssemblyAI | Best accuracy on trade vocabulary; cost-effective at $0.006/min |
| Scope extraction | GPT-4o with trade-specific prompts | GPT-3.5, Claude, open-source | Best accuracy on construction/trade terminology; structured JSON output |
| E-signature | Hellosign API (Dropbox) | DocuSign API, PandaDoc | Best API pricing for embedded signature; no end-user account required |
| PDF generation | Puppeteer/Headless Chrome | pdfkit, jsPDF | Pixel-perfect PDF from HTML template; easiest to brand |
| Backend | Node.js + Supabase | Rails, Django, Firebase | Speed to MVP; Supabase auth + real-time + storage in one |
| Mobile | React Native | Flutter, native iOS/Android | Single codebase, web + iOS + Android; large talent pool |

What we need
We're looking for a trades operator — someone who has run a service business (painting, cleaning, pest control, HVAC) or sold software to that market. You know why proposals matter. You know what solo operators actually use. You have credibility with the audience we're selling to. Optionally: early-stage SaaS experience (0→$500K ARR). Capital experience welcome but not required — the business is designed to be bootstrappable at $27.5K.
