SEATTLE — Seattle-based marketing startup MediaPact launched its direct media buying marketplace in 2026, offering brands and digital publishers a unified platform to automate flat-fee sponsorship deals as artificial intelligence alters traditional web browsing and advertising models. Founded by veteran marketing executive Lacie Thompson, the company aims to eliminate the friction of manual ad buys—such as sponsored articles, newsletter features, and podcast mentions—as marketers look for new ways to gain visibility in an AI-dominated landscape.
The Evolution of Search and Answer Engine Optimization
For more than two decades, digital advertising relied heavily on pay-per-click models and programmatic banner placements designed to capture search engine traffic. However, the rise of generative AI search engines has fundamentally disrupted this funnel by delivering direct answers to user queries on-screen, severely reducing external link clicks.
Industry data indicates that content cited as source material within AI answers converts at 4.4 times the rate of standard digital web traffic. This dynamic is driving an urgent shift toward Answer Engine Optimization (AEO), where brands compete to be referenced inside high-authority editorial sources that AI models crawl and cite.
To remain visible in AI summaries, brands are actively pivoting away from programmatic ad networks and seeking direct placements within trusted editorial publications, established newsletters, and niche media outlets.
Replacing Manual Workflows with Standardized Marketplaces
Despite representing a massive portion of modern marketing spend, flat-fee direct media buying has historically suffered from outdated software infrastructure. Nine out of ten publishers interviewed during MediaPact’s market research reported managing direct sponsorship deals through manual email chains, bespoke PDF insertion orders, and unorganized spreadsheets, often chasing unpaid invoices for up to 60 days.
MediaPact standardizes direct media inventory into a searchable, transparent online platform where buyers can discover creators, negotiate terms, sign digital insertion orders, and process payments in one place. By centralizing the transaction pipeline, the startup replaces multi-week email exchanges with an automated workflow designed to make buying sponsorships as efficient as booking a flight.
AI-Driven Development and Early Market Traction
The creation of MediaPact highlights a broader operational shift in how modern software startups are built. Thompson, who previously led marketing initiatives at major corporations including Expedia, Blue Nile, and New Engen, launched the company without formal computer coding experience or a traditional engineering team.
Using the AI software development tool Claude Code, Thompson independently built and deployed the platform’s entire technology stack, incorporating React, TypeScript, Supabase, and Stripe Connect. The single-employee company, supported by four industry advisors and contractors, raised a $200,000 friends-and-family funding round and has already onboarded prominent digital publishers, including Penske Media, BroBible, and Gadget Review.
Reclaiming Brand Value Over Last-Click Metrics
The startup’s business model directly addresses systemic issues associated with performance marketing and attribution tracking. For years, digital advertisers relied heavily on last-click attribution models, which frequently penalized top-of-funnel media placements in favor of final conversion channels.
MediaPact focuses on flat-fee guaranteed placements, ensuring content creators and publishers receive predictable compensation for their audience size and editorial authority. The platform is seeing early demand from mid-stage consumer brands seeking top-of-funnel audience growth after reaching adoption ceilings on traditional paid social networks like Meta and Google.
Industry Implications and What to Watch Next
MediaPact’s emergence underscores two major trends reshaping the technology landscape: the restructuring of digital marketing driven by AI search behavior and the rise of non-technical founders using AI tools to build commercial B2B software. As generative search tools continue to reduce traditional web traffic, corporate marketing budgets are expected to reallocate heavily toward direct, high-authority publisher partnerships.
Moving forward, industry analysts will watch whether MediaPact can solve the traditional marketplace supply-demand balance by rapidly scaling enterprise buyer adoption. In addition, the platform’s long-term performance will offer a clear benchmark for whether solo founders leveraging AI developer tools can successfully compete against established enterprise adtech providers.
