What Developing I T does
Developing I T, doing business as Optiseller, is a UK-based SaaS company founded in 2004 and headquartered in Stirling that builds AI-driven data analytics tools for online retailers selling on eBay and other marketplaces. Its core product, the Optiseller Suite, is a unified platform offering 20+ tools organized into modules covering Market Research, Optimisation, Compliance, Reporting, and Analytics, with specialized features such as Aspect finder+ for identifying missing item specifics, Single Listing Review for listing-level KPI insights, and Brand Data Reporting for brand-side marketplace performance. The underlying technology layer comprises AI-Driven APIs built on proprietary algorithms, processing structured listing data and text for predictive analytics, recommendation, and optimization use cases.
Optiseller monetizes through a SaaS subscription model with service tiers including the Growth Programme, Data as a Service, and Brand Reporting, supplemented by higher-touch engagements where dedicated marketplace experts work alongside sellers. The go-to-market is sales-led: prospective enterprise customers are directed to contact sales, while existing users access tools via a self-serve portal at app.optiseller.com. Distribution extends into the eBay Seller Hub through Optiseller Lite, enabling in-marketplace evaluation and optimization.
The company serves three primary customer segments — online retailers, brands, and agencies — and claims a global footprint of 65,000+ users, with 2.3 billion products analyzed since launch and 70 million+ listings reviewed each week. Named enterprise customers displayed as trust signals include Shark, Bosch, Worx, BuyItDirect, Loop, and eBay. Leadership is led by Craig MacCallum, Managing Director and CEO. The company is privately held, has 11-50 employees, and shows no disclosed funding rounds, suggesting a bootstrapped operating profile.

Developing I T competitors and assessment
Company assessmentDirect peers
- InkFrog: Direct eBay-focused listing and template management tool. Highly comparable because InkFrog serves the same eBay seller niche with listing optimisation, design, and analytics — directly overlapping with Optiseller's core eBay use cases.
- ChannelEngine: Multi-marketplace integration and analytics platform. Comparable because it serves the same brands and agencies seeking to optimise product listings and performance across marketplaces, with similar data-driven optimisation positioning.
- Sellbrite: Multi-channel listing and inventory management SaaS for online sellers. Comparable because it serves the same SMB-to-mid-market seller segment with centralised listing tools and marketplace optimisation functionality similar to Optiseller's multi-channel module.
- Zentail: Multi-channel eCommerce management platform for brands and sellers. Comparable because it offers centralised listing management, optimisation, and analytics across multiple marketplaces — overlapping directly with Optiseller's multi-channel listing value proposition.
- Codisto: eBay listing and multi-channel sync tool. Direct comparable because it focuses specifically on connecting sellers to eBay with listing optimisation and synchronisation features that closely parallel Optiseller's listing optimisation capabilities.
Broad incumbents
- Sellercloud: Broader eCommerce operations platform with multi-channel listing, inventory, and analytics. Comparable as a wider-portfolio incumbent offering overlapping marketplace optimisation capabilities, though Sellercloud serves a broader operational scope beyond Optiseller's analytics specialisation.
- Helium 10: Established all-in-one SaaS suite for marketplace sellers (primarily Amazon). Comparable because it offers keyword research, listing optimisation, and analytics — the same core toolkit categories as Optiseller, but focused on Amazon rather than eBay.
- Jungle Scout: Marketplace seller research and analytics platform. Comparable because it provides buyer demand data, competitor analysis, and category insights similar to Optiseller's Market Research module, though concentrated on Amazon.
- Terapeak (eBay Research): eBay's own marketplace research and analytics tool. Highly relevant competitive reference because it offers free/integrated seller analytics directly from the marketplace platform, creating potential overlap with Optiseller's market research and reporting modules.
Emerging players
- SureDone: Multi-channel eCommerce platform with listing, inventory, and analytics modules. Comparable as a smaller-scale player serving a similar SMB-to-mid-market seller base with marketplace optimisation features, though with broader operational scope.
