01
Product definition sprint
Commercial: fixed and prepaid.
Use when: product intent, feasibility, architecture or
rescue scope is still ambiguous.
Leaves behind: baselined requirements, executable
performance model, partition scorecard, risks, verification
strategy and milestone SOW.
02
Milestone risk-share
Commercial: fixed foundation fee plus a deferred tranche
per evidence gate.
Use when: the outcome is important, bounded and
objectively testable.
Leaves behind: accepted system capability, reproducible
evidence and no single oversized project-end holdback.
03
Acceleration runway
Commercial: fixed program-phase fee covering a named
backlog, delivery cadence and quarterly evidence gates.
Use when: architecture, RTL, firmware and lab priorities
must converge across a sustained product phase.
Leaves behind: accepted increments and predictable access
without converting engineering into an activity ledger.
04
Fractional design authority
Commercial: fixed fee per governed product phase with
evidence-gate bonuses.
Use when: a team needs senior ownership of architecture,
partition, reviews and verification sufficiency.
Leaves behind: governed decisions, risk disposition and a
stronger internal team.
05
Build, operate, transfer
Commercial: setup, operating and acceptance-based
transfer fees.
Use when: CI, regression, emulation, prototyping or
agentic workflows must become durable internal capability.
Leaves behind: stable operations, documentation, training
and transferred ownership.
06
Runway-preserving co-build
Commercial: paid definition and a meaningful cash
foundation, with a capped portion of earned fees deferred to an
objective evidence gate or a defined financing event. Equity or
options can be considered separately.
Use when: a selected funded startup must preserve runway
while closing a consequential, objectively testable product
gate.
Leaves behind: accepted engineering evidence and aligned
economics without using equity as a substitute for delivery
cost. Deferred terms require written legal and tax review.
07
Time and materials
Commercial: billed by the day or hour against an agreed
rate card.
Senior FPGA and embedded engineering delivered against an
agreed rate card, billed by the day or hour with transparent
timesheets. No fixed scope or milestone commitment.
Best for: open-ended or exploratory work, staff
augmentation, and support where the scope is expected to
change.
This is the traditional consulting model.
