Spectacle

Spectacle is a marketing attribution and analytics platform that connects ad spend, website activity, product usage, and CRM and billing data into one revenue journey, from the first anonymous visit to a closed-won deal or payment. Marketing teams, growth leads, and agencies use Spectacle to see which campaigns create pipeline and revenue, then send that revenue back to their ad platforms as the signal to optimize on. It is built for B2B companies and long-cycle B2C businesses, such as real estate, education, finance, and insurance, where buyers come back many times before they convert. How it works: one tracking snippet, or server-side Google Tag Manager on your own domain, collects first-party data. Spectacle stitches every touchpoint from anonymous visitor to person, company, deal, and revenue, using the CRM and payment data you already have. Key capabilities: • Multi-touch attribution: compare Linear, First Touch, Last Touch, and U-Shaped models across paid, organic, and AI channels, with revenue by channel, ROAS by campaign, and LTV by cohort. • Journeys that don't expire: there is no lookback window, so a first visit from a year ago still counts toward the deal that closes today. • Company-level attribution: group everyone from the same company into one B2B journey and see the buying committee over time. Lens identifies the companies behind visitors who never fill in a form. • Revenue back to ad platforms: sync CRM stages and revenue as conversions to Google, Meta, and LinkedIn, and build audiences and exclusions from live pipeline. • Funnels and reporting: build funnels from any page or event, break them down by source, keyword, and ad group, and share custom dashboards. Integrations include HubSpot, Salesforce, Microsoft Dynamics 365 (including custom tables), Odoo, Pipedrive, Monday, Zoho, and ActiveCampaign; Google Ads, Meta Ads, LinkedIn Ads, Microsoft Ads, and Reddit Ads; Stripe and Chargebee; GA4, Google Tag Manager, Segment, and a REST API. Spectacle can also host and manage server-side Google Tag Manager for you, with a tracking plan and monitoring of incoming events. Plans start at $99 per month, billed annually, and every plan includes a 14-day free trial with no credit card required. Enterprise adds single sign-on (SAML, OIDC, and SCIM), a service level agreement, and priority support via Slack Connect. Data is hosted in the EU on AWS. ISO 27001 and SOC 2 are in progress.

LeadsStream

Most businesses invest heavily in driving traffic to their website. Few know what to do when that traffic arrives, because they cannot see who is there. LeadsStream changes that. It identifies the UK businesses visiting your website in real time, giving your sales and marketing teams the visibility to act on genuine buying intent before it goes cold. When a prospect lands on your site, LeadsStream matches that visit against the Verified Business Universe, enriches it with company intelligence, including sector, size and contact information, and delivers it directly to your team. The result is a live feed of businesses that have already shown interest, with the verified data needed to act on it. LeadsStream is designed specifically for the UK B2B market. The underlying data is UK-focused, human-verified and continuously maintained, so the intelligence your team acts on is accurate, not approximate. Sales teams use LeadsStream to prioritise outreach around companies actively researching their solutions. Marketing teams use it to understand which campaigns and channels are driving real business interest, not just traffic volume. Managing directors use it to connect website activity to pipeline in a way that was previously invisible. · Real-time identification of UK businesses visiting your website · Verified contact intelligence to support immediate outreach · CRM and marketing automation integration · Built on Market Location's human-verified UK B2B data infrastructure · GDPR and PECR compliant by design If your website is generating interest but your pipeline is not reflecting it, LeadsStream closes that gap.
