ProsperOps leans hard on Convertible Reserved Instances (CRIs) - constantly splitting, merging, and exchanging them to chase coverage on a limited slice of EC2.That trick covers less and less of modern AWS footprints, and it does nothing to mitigate risk on the rest of your stack.
Cloud Capital delivers materially higher, guaranteed savings across your whole bill - commitments placed in your account, full risk protection, and finance-grade forecasts you can defend.
Trusted by




























Cloud Capital helps Finance and Engineering teams cut waste, lower cloud costs, and forecast spend with confidence.

ProsperOps focuses on CRI-driven coverage for a subset of EC2 - coverage that AWS is steadily constraining.
Cloud Capital optimizes commitments across all committable AWS services: EC2, ECS, RDS, ElastiCache, OpenSearch, and more.
Real savings come from your whole estate - not just the slice CRIs can still touch.
Risk
ProsperOps offers optimization—not risk backstop. Outside their CRI game, there is no commitment risk mitigation.
Cloud Capital sets a pre-agreed Guaranteed Savings Rate and takes the full commitment risk across all covered services.
Your savings are contracted, predictable, and protected - not dependent on a bot keeping up.
Savings
ProsperOps’ value drops during architecture changes and re-allocations when CRI coverage stutters.
Cloud Capital runs commitment optimization in parallel with your migration roadmap - and we carry the commitment risk while you refactor.
You do not pause savings just because engineering is changing shape.
Control
ProsperOps builds deep dependency on CRI split-merge-exchange. It works until it does not - then it is messy to unwind.
Cloud Capital places straightforward, portable commitments directly in your payer account with delegated access. You own them. You approve them. You can move them.
Zero black box. Full auditability. No lock-in.

CRI-focused coverage on a subset of EC2
Minimal impact
Optimization only—no commitment risk backstop
CRI coverage can stall or drop
Heavy reliance on CRI split-merge-exchange
ESR-first optimization dashboards
Complex CRI lattice to maintain and unwind
High operational dependency on CRI mechanics
Cloud Capital
Estate-wide optimization across EC2, ECS, RDS, ElastiCache, OpenSearch, more
Volume discounts across all spend, including non-committable
Contracted Guaranteed Savings Rate with full commitment risk protection
We keep optimizing during migrations and carry the risk
Right instrument mix for plan stability, not instrument gymnastics
Driver-based, board-ready forecasts tied to revenue, COGS, and margins
Native commitments in your payer account, full visibility and portability
No lock-in, clean structure, easy to audit and exit
Can we use ProsperOps for CRIs and Cloud Capital for everything else
Yes. If you want to keep a shrinking CRI tactic alive, we can run the rest of your savings and risk protection in parallel - and we will still deliver volume discounts across your whole bill.
How do you compare savings vs ProsperOps
Connect your AWS account read-only and we will produce a side-by-side: total savings uplift, risk coverage, and forecast accuracy at the P&L level.
What happens during a re-architecture
You do not lose savings. We optimize in parallel with your engineering plan and we take the commitment risk while coverage shifts.
Do you actually guarantee savings
Yes. We contract a Guaranteed Savings Rate across covered services, placed directly in your payer account. No clawbacks. No games.
ProsperOps turns CRIs into an optimization game on a shrinking portion of EC2. It is clever, but narrow - and it does not protect you when usage changes or when you step outside CRI-friendly workloads.
DoIT’s Flexsave relies on a banned practice that AWS has publicly stated violates their Terms.If AWS audits, you’re the one left holding the liability. If DoIT pulls their accounts, your “savings” disappear overnight.

Full commitment risk protection across all committable services
Volume discounts even on non-committable spend
Runs alongside migrations so you never miss savings
