REAL COST CALCULATOR

What Obsidian actually costs

Sticker price isn't the real cost. We add implementation, training, and a probability-weighted lock-in penalty.

1500
Obsidian is free-tier. Real cost is the implementation effort ($30K) plus training ($25K for 50 seats) plus your team's time. Total over 3 years: $60K.
Heuristic — uses median industry rates. Negotiate to beat list pricing; the implementation and training estimates assume reasonable rollout.
NEGOTIATION TIMING

When to negotiate Obsidian

Vendor sales pressure is non-uniform — quarter-close, year-end, and post-funding-round are your high-leverage windows.

LOW LEVERAGE75 days to Q3 close

Low pressure window. Reps have time on their side. If you can wait, target the last 30 days of Q3 for materially better economics.

Calendar-quarter heuristic. Vendors on fiscal-year ≠ calendar may shift these windows; ask the rep what their fiscal year-end is.
BUYER'S QUESTION LIST

Take this to your sales call

8 questions vendor sales teams steer around — generated from Obsidian's pricing tier, lock-in profile.

  1. 1
    PRICING
    Obsidian starts on the free tier. What forces an upgrade — specific feature gates, usage caps, or support tier? Give me the realistic monthly bill at small scale.
  2. 2
    CONTRACT
    Auto-renewal: how many days notice is required to terminate, and what happens if we miss the window? Will you commit to a renewal-reminder email at 90 and 60 days?
  3. 3
    MIGRATION
    Data export: what's the complete spec — format, frequency, and what data does the export NOT include? After contract end, how long do we have read-only access?
  4. 4
    MIGRATION
    Implementation runs Same day for basic use; weeks to tune a personal system. Who from your team is included by default, and who do we add at additional cost? Is a CSM assigned?
  5. 5
    FIT
    Connect us with 2-3 reference customers at our company size in your industry — not the case-study list, customers who've been live for 18+ months.
  6. 6
    INTEGRATION
    Obsidian lists 4 integrations including GitHub, iCloud Drive, Readwise. Which of OUR existing tools — bring our list — have you confirmed shipping integration with versus "on roadmap"? Show me the actual status.
  7. 7
    VENDOR
    Track record over the last 18 months: any pricing model changes, executive departures, layoffs, M&A activity, or material customer churn we should know about?
  8. 8
    VENDOR
    If you're acquired or shut down, what's the contractual continuity — source-code escrow, data portability, transition period? Show me the actual clause.

ANTI-DEMO CHECKLIST

What to actually test in the demo

Vendor sales teams script demos to maximize close rate. Here's what they'd rather you not test — derived from Obsidian's lock-in profile.

  1. 1
    PERFORMANCE
    Bring YOUR data, not their demo data. Insist on running the demo workflow against a sample of your real records, files, or queries. If they refuse — that's a signal.
  2. 2
    PERFORMANCE
    Obsidian demo will be built around the happy path. Ask: "Show me what happens when [the most common failure mode in our context]" — make them improvise.
  3. 3
    EDGE CASES
    Push the limits live: largest dataset, longest workflow, most users concurrent. Vendors prep demos for medium loads — your real-world usage might 10x what they show.
  4. 4
    EDGE CASES
    Mobile and offline behavior: how does Obsidian degrade on slow connections, on iPad, in airplane mode? Test in the demo if your team uses these surfaces.
  5. 5
    PRICING
    Find the upgrade triggers. Which features force a paid plan? Which usage limits trigger overage? Get the rep to demo your team hitting each cap.
  6. 6
    INTEGRATION
    Vendors love their integration logo wall. Test the actual depth: pick the 2-3 (GitHub, iCloud Drive-style) integrations you depend on most, and ask the rep to demo a real two-way data sync, not a marketing screenshot.
  7. 7
    INTEGRATION
    API and webhook reality check: rate limits, payload size limits, retry behavior, auth refresh handling. Ask for actual API docs in the demo, not "we'll send those."
  8. 8
    MIGRATION
    Demo the full data export workflow. Even with low lock-in, you want to see how clean the exit looks before signing.
  9. 9
    SUPPORT
    Submit a real support ticket DURING the demo. Use the actual support channel customers use, not the rep's email. Time the response. This is your most honest data point about post-sale reality.
  10. 10
    SUPPORT
    Ask to be connected with a customer in the demo who you can email TODAY (not "we'll arrange a reference call next week"). The vendor's confidence in their references is a tell.
Print it, bring it to the demo call, and check items off as you cover them. The rep noticing you have a list changes the energy.
