why Aries Tender
Our team draws on 18,000+ tracked projects, years of structured tender data, and direct transaction experience to assess risk across five dimensions. With no template answers and no bidder relationships to manage, our analysts focus on one thing: giving you a complete, honest picture of what you're buying.
We don't hold project responses, take ownership stakes, or earn fees from bidders. Every assessment we produce is paid for by clients alone. That means when we identify a risk, we report it honestly and completely, and hold no interest in steering you towards any particular project.
Our team has over 60 years cumulatively in the public sector and has facilitated over 55 million notices of submitted bids, which gives us a commercial lens that traditional research organisations simply don't have. We understand how risks materialise at the deal level, where contracts fall apart, and what scrutiny your portfolio will face over time.
Not every transaction warrants the same depth of analysis. Our tiered framework lets you match the level of diligence to the size and complexity of what you're buying, whether that's a rapid automated screen of 200 proposals or an on-site assessment for a ten-year offtake agreement.
Our database spans 18,000+ projects, 23 portals, and years of tender submissions, giving our analysts benchmarks and context that aren't publicly available. When we assess a developer's track record or a methodology's issuance history, we're drawing on data we've built, not borrowed.

Harrow Facilities engaged Aries Tender as an extension of their team to assess tender proposals and shortlist projects as part of their process to identify the best options for their tender response programme.

Yes. Many high-value projects carry no public rating at all, which can rule them out of a buyer's process by default. Because our framework applies to any project where you know the country, developer, and methodology, we can assess unrated projects and open up more competitive options that others would overlook.
Project documentation tells you what a bidder intends, not always what has happened. Our Geo screening tool uses satellite data to check a project's physical characteristics, for example whether forest cover and land use line up with the claims in the project design document. It's a practical way to test a project before you commit, and to spot issues a paper review would miss.
We offer three compliance review levels, and each one builds on the last. Level 1 is a fast, high-level screen that flags red flags early and helps you narrow a shortlist. Level 2 is a desk-based assessment of a project's environmental integrity, covering additionality, greenhouse gas accounting, permanence, external risks, and co-benefits. Level 3 is an in-depth, investment-grade review, including interviews, data room access, and site visits where needed.You can match the work to the transaction rather than paying for more analysis than you need.
We assess a project across five areas: the project itself, the policy environment in the host country, the methodology behind the responses, the developer's track record, and market conditions. Looking at the same areas every time keeps our findings consistent and comparable, whether you're weighing up a cookstoves project in one country or a forestry project in another.
Quality is subjective and hard to compare across very different project types and countries. Risk is measurable. We flag specific, structured risks so you can weigh them against your own risk appetite and make the call yourself. Every finding is backed by its data sources and our analysts' reasoning, so you can audit how we reached a conclusion and justify the decision internally.
Often public tender compliance review comes from organisations that are paid by bidders to cover them, opening up potential for misaligned incentives. We work differently. We hold no project inventory, take no ownership stakes, and we're paid only by our clients, never by bidders. That means our findings reflect the risks in a project, and nothing else. You get a genuinely independent view, much like having your own analyst on the team.
Buying well is only half the job. Risks can emerge after purchase, from policy shifts to changes on the ground, so we can monitor projects over time and alert you to issues that affect responses you already hold. That keeps your portfolio protected well beyond the point of sale.
