Vector, a Boston-based contact-level advertising platform, has raised $10M in Series A funding led by SignalFire and HubSpot Ventures. The company de-anonymizes website visitors and ad clickers to create precise, dynamic ad audiences for platforms like LinkedIn, Google, and Meta. The capital will fuel operations expansion and AI platform development, including the new Marketing Control Plane (MCP) for querying campaign data.
Martech Plateaus at 15,505 Tools
The funding arrives as the martech landscape plateaus at 15,505 tools in 2026, up just 0.79% from prior year per ChiefMartec. This signals consolidation, with AI as the key differentiator amid fragmented stacks. Vector's contact-level precision positions it to cut through the noise. Meanwhile, related player Hightouch raised $150M Series D at $2.75B valuation in April 2026.
B2B Ads Miss 98% of Clickers
B2B marketers face anonymous traffic and uncaptured ad clicks, with 98% of clicks going unseen without de-anonymization tools. Traditional account-based marketing (ABM) targets companies, not individuals, leading to inefficient spend in complex buyer journeys. Post-cookie privacy shifts demand first-party signals from site visits, CRM, and ads. Vector addresses this by revealing named contacts from real-time behaviors.
Reveal Turns Ghosts into Buyers
Vector's Reveal product de-anonymizes site visitors and ad clickers, even without conversions, syncing to CRM. Target builds signal-driven audiences across channels, while Bid Agent optimizes bids in real-time for lower CPC. Unlike account-focused players, Vector enables contact-level precision with AI orchestration via MCP. Customers report gains like Goldcast's 17x ROI and 3x CTR.
As Vector CEO Joshua Perk explained:
"The prevailing narrative is that AI will replace marketers. We believe AI makes marketers better, not obsolete."
SignalFire Validates AI GTM Bet
SignalFire, with $3B AUM and AI platform Beacon, led the round alongside HubSpot Ventures, which backs martech ecosystem plays. SignalFire's portfolio includes Tofu and Session AI in B2B GTM, signaling conviction in Vector's contact-level infrastructure. HubSpot Ventures adds SMB demand gen expertise, with exits like Goldcast to Cvent. This duo bridges AI muscle and martech validation.
Varun Ramakrishnan of SignalFire noted:
"The teams that win in B2B GTM are the ones that move faster with better signals."
Martech Scales to $569B Horizon
The martech market stands at $222.53B in 2026, projected to reach $569.34B by 2034 at 12.46% CAGR. Competitors like Influ2 ($13M funded), 6sense ($426M), and Demandbase ($175M+) dominate ABM, but focus on accounts over contacts. Vector carves a niche in dynamic, privacy-compliant ad targeting amid rising state laws.
Air Force Vets Pioneer Precision
Founded in 2022 by former Air Force veterans and Drift sales engineers, Vector brings military-grade precision to B2B ads. Founders Joshua Perk and Nick Masters emphasize contact-level over legacy ABM. Their playbook includes customer playbooks from OpenBrand and Airbyte, proving scalable performance.
MCP Launch Powers Expansion
With the Series A, Vector launches MCP for natural language queries on buyer and campaign data. Funds target product development, hiring in demand gen, and scaling integrations like Clay and HubSpot. Recent traction includes Bid Agent GA with 65% lower CPC claims from beta, plus nominations like Best B2B Martech.
