01Common complaints

1) If an organization requires extensive third-party validation immediately - Procurement processes that demand abundant independent reviews and peer references may find the current public footprint insufficient. 2) If an organization has strict data-handling rules that prohibit sending content to external AI services - Even if a vendor asserts specific training or data-use policies, some firms disallow external AI processing for client-sensitive data. 3) If the organization is committed to Microsoft 365 Copilot with existing governance and integration - Microsoft Copilot may be sufficient for organizations seeking consolidation with existing Microsoft tooling and governance. 4) If the primary need is deterministic charting and layout rather than generative content - Tools such as think-cell may provide more predictable charting and formatting behavior for deterministic workflows. 5) If the primary requirement is spreadsheet formula generation only - The original Tersho formula generator competes in a commoditized space; alternatives (Copilot, ChatGPT, Excel Formula Bot) may be simpler to evaluate and adopt.

Publicly confirmed limitations

tersho.com site access limitations: During this research run, direct access to tersho.com was blocked due to robots.txt fetching issues, which limited verification of current tersho.com messaging.

Limitations to validate during evaluation (not confirmed)

Quality when applied to highly customized corporate templates.
Offline or disconnected operation: vendor FAQ references offline use, but specifics were not captured in accessible excerpts.
Enterprise admin controls (SSO/SCIM/audit logs) are not clearly documented in publicly accessible sources for this run.

02Why they buy

Unique selling points supported by accessible sources (primarily vendor statements): - Vendor states the product operates directly in PowerPoint with native PPTX support. - Vendor describes on-brand adaptation by learning from prior decks (positioned as a product capability). - Vendor publicly references SOC 2 Type II audits and includes privacy policy details about cross-border transfers and vendor relationships. Where competitors have advantages: - Microsoft Copilot: enterprise distribution, integrated identity and admin controls, and broader vendor stability. - think-cell / Macabacus: established workflows and predictable ROI for slide production tasks.

03Field reports

Review platform availability (Gartner / G2 / TrustRadius)

- Gartner Peer Insights: No Tersho/Slidely product profile was found accessible in this run; Gartner’s site is often gated, and search results did not surface a direct vendor listing. - G2 / TrustRadius / Capterra: No clear TrustRadius or Capterra profile for Tersho or Slidely AI was found in this run. A G2 result for "Slidely" appears to refer to an unrelated product (video/ad creation) and should be treated as a name-collision rather than evidence for this vendor.

Community/social proof (Reddit)

Early reactions to the original Tersho formula tool included user interest and exploratory comments, consistent with initial product launch activity rather than validated enterprise outcomes.
A community post referenced free early access to the current product and suggested the tool can adapt to past presentations; the post appears promotional and not an independent evaluation.

Vendor-published testimonials (Slidely AI website)

The Slidely AI website displays testimonial-style quotes attributed to users. Example excerpts include statements that an initial draft deck required only light edits and that a user experienced quick vendor responsiveness.

Critical note: These are vendor-curated testimonials (not independent review-platform entries). They offer limited evidence and should not be treated as representative without independent validation.

Common themes (limited evidence base)

Where independent reviews are scarce, available signals suggest potential value where speed and formatting consistency are priorities.
Buyers are likely to prioritize PPTX fidelity (preservation of layout) and brand compliance when evaluating the product.
For the older formula tool, novelty was notable early on; competition in the formula-assistance space has since increased.

Public case studies found

No formal third-party case studies were found in accessible sources for Tersho/Slidely AI during this run.

Vendor-website testimonial-style mini cases

Slidely AI’s website presents user quotes describing time savings and vendor responsiveness.

Critical evaluation:

These outcomes are not independently verified, do not provide baseline comparisons, and do not disclose methodology (e.g., how "time saved" is measured, sample size, or user segment).

04Best fit

ICP for the current Slidely AI direction

- Company size: Mid-market to enterprise (organizations ranging from mid-sized to very large), where slide output is a frequent and material deliverable. - Industries: Consulting, technology, finance, professional services, corporate strategy, and sales enablement. - Personas: - Decision makers: Heads of Strategy, consulting partners, RevOps leaders, and IT procurement teams (for add-in approval). - End users: Analysts, associates, and sales teams who create decks. - Pain points: - Excess time spent formatting slides. - Brand and template inconsistencies across decks. - Manual Excel-to-PowerPoint updates that lead to stale numbers. - Strong fit signals: - Organization standardized on PowerPoint. - Repetitive deck workflows and templates. - High cost of associate/analyst time for slide production.

ICP for the original formula tool

Individuals or small teams performing intensive spreadsheet work who require rapid formula drafting or plain-language explanations of formulas.

05The pitch

What the product does (core value proposition)

Based on accessible public sources, Tersho has had two distinct product narratives over time: 1) Original (2022) — Spreadsheet formula AI assistant - A Google Sheets add-on and Excel add-in that converts natural language into spreadsheet formulas and can explain complex formulas. - Distribution via: - Google Workspace Marketplace listing for a Sheets add-on (describes AI to write formulas and to explain formulas). - Microsoft AppSource listing for an Excel add-in (Tersho: AI formulas). 2) Current (2025–2026) — Slidely AI PowerPoint assistant (likely the active focus) - A PowerPoint add-in and workflow that creates and edits slides from natural-language prompts, applies brand formatting rules, formats tables, links Excel data to slides, and performs deck-quality checks (brand/format consistency) and other deck-production automation. - The Slidely AI website and YC profile describe native PPTX support and automated slide creation that positions shapes individually.

Target market and positioning

Tersho (original): individuals and teams working extensively in spreadsheets—analysts, finance/FP&A, operations, and non-technical users who need formulas generated or explained quickly.
Slidely AI (current): professionals and teams that rely on PowerPoint for client- or executive-facing presentations, including consultants, corporate strategy teams, sales, and finance groups.
